The present invention relates to an apparatus for recycling fly ash having a quantum energy generator therein, and more particularly to an apparatus for recycling the fly ash generated after burning coal in thermal power plants, which is the combustion wastes generated from the thermal power plants, etc., into construction materials such as cement substitutes, environment-friendly cover materials, etc. by burning and removing unburned pulverized coal out of the fly ash through the thermal electrons discharged from a thermal decomposition process at a high temperature, the thermal electrons and electric charges discharged from a high-voltage discharge process, as well as at least one electrochemical reaction out of dissociation, excitation, oxidation and reduction, and removing a glassy membrane coated on fly ash particles through an elastic collision between the fly ash particles and the charged particles including electrons, ions or the like, and thermal electrons, thereby solving the problems raised so far, such as a decrease in compressive strength, etc. caused by containing unburned pulverized coal in the fly ash and when recycling the ash derived from a glassy membrane coated on a surface of ash particles.
The fly ash is a particle of micrometer size (μm) generated during a combustion process of coal in thermal power plants producing electricity, and this particle may contain various oxides such as silicon dioxide (SiO2), calcium oxide (CaO), sodium oxide (Na2O), magnesium oxide (MgO), potassium oxide (K2O), barium oxide (BaO), alumina (Al2O3), iron (Fe2O3), etc. as well as carbon residues (pulverized coal).
The fly ash has been used for many purposes as an additive for various materials. For example, when being mixed with lime and water, the fly ash forms a cementitious composition having properties very similar to those of Portland cement. Due to this similarity, the fly ash may be used to replace a part of cement in concrete.
In case of manufacturing concrete by using the fly ash, the amount of cement used may be reduced and thus the amount of carbon dioxide generated from a process of manufacturing cement as well as the cost of manufacturing may be reduced as much as the amount of cement used is reduced. Furthermore, it is also possible to achieve an effect of improving performance, such as more convenient construction due to an increase in fluidity, better long-term strength, more chemical durability and the like.
However, when using the fly ash as an admixture of concrete, the fly ash is subject to quenching treatment at a high temperature (1300° C.) during a generation process thereof, and thus materials such as silicon dioxide (SiO2), calcium oxide (CaO), magnesium oxide (MgO), barium oxide (BaO), aluminum oxide (Al2O3), etc. are condensed into a spherical shape and formed as a glassy membrane on a surface of particles, thereby obtaining latent hydraulic property, which may not directly react with water in itself. Further, this glassy membrane has a property of being destroyed when being exposed to an alkali environment and thus induces a hydration reaction through an alkali stimulant such as NaOH, KOH and Ca(OH)2.
To solve such problem, however, in case of using a strong basic material as a substitute material for the alkali stimulant, there is a risk of causing a corrosion in contact with a worker's skin and construction costs are also increased as an expensive material.
Further, the fly ash has unburned pulverized coal (dust coal) therein, and the unburned pulverized coal refers to an amorphous carbon particle which remains unburned after incomplete burning inside a boiler of a thermal power plant. If the fly ash entraining a large amount of unburned carbon is used as a substitute material for cement, it is necessary to add a large amount of air entraining and water reducing agent (AE) to secure an equal slump and there also occurs a problem of deteriorating performance such as a decrease in durability, etc.
If fly ash is added to concrete, preferred characteristics of cement are provided, but the unburned carbon in the fly ash may fail to sufficiently entrain air in concrete. Thus, to control an amount of air entrained in a process of mixing and depositing concrete, a surfactant is added to a concrete mixture to stabilize an air void system.
As described above, there is a demand for providing a method and system for treating the fly ash better, which may overcome difficulty of mixing a bulk of the fly ash with a liquid treatment agent.
Further, there is a need for providing a method and system for manufacturing uniform fly ash, which does not require a drastic change in a current method for manufacturing and treating fly ash, thereby minimizing investment costs for carrying out the former method accordingly.
To treat fly ash above, Korean Registered Patent No. 10-1801530 (Apparatus for treating coal ash and treatment method for coal ash using the same) discloses a method for collecting exhaust gas discharged from a boiler of a coal-fired thermal power plant to separate such gas into raw gas including ash content and sulfur compounds, preparing sulfuric acid by using the separated sulfur compounds, allowing the prepared sulfuric acid and the ash content to come into contact with each other to make a mixture, separating slurry and liquid extract from the mixture, and drying the separated slurry and the liquid extract, and this invention does not mention any technique for treating unburned pulverized coal out of fly ash and removing a glassy membrane coated on a surface of the fly ash.
Korean Patent Publication No. 10-1547959 (Method for collecting unburned carbon from bottom ash using a corona discharge type electrostatic screening method) provides a technique in which unburned carbon is collected and separated by particle size in order to recycle the bottom ash reclaimed in coal ash generated after burning coal in a thermal power plant into construction materials, etc., crushed and floating impurities are removed to improve screening efficiency, a sieving separation is performed to concentrate a content of unburned carbon, iron powder is separated by applying a magnetic field of 2000 gauss to the bottom ash with concentrated unburned carbon, and the bottom ash with the iron powder separated therefrom is subject to a corona discharge type electrostatic screening so as to collect unburned carbon from the bottom ash. This technique may not remove the glassy membrane of bottom ash particles.
Korean Patent Publication No. 10-1514124 (Method for removing unburned carbon from fly ash using plasma) provides a technique in which 1.2 g of fly ash is dispersed inside a chamber in a plasma treatment process, an oxidant such as oxygen (O2), vapor (H2O), mixed fluid (O2+H2O) of oxygen and vapor, etc. are added thereto, a pressure inside the chamber is reduced to 0.5 torr, and the resulting fly ash is heated to 150° C. and subject to plasma treatment so as to remove the fly ash up to less than 1%. This technique has problems of reducing the pressure to 0.5 torr inside the chamber, continuously consuming the oxidant, and not removing a glassy membrane of the surface of fly ash. Further, this device is too complicated to be enlarged and requires high investment and maintenance costs.
As described above, the conventional techniques for treating the fly ash collected from the gas of coal burned during a process of thermal power plants have been insufficient in terms of treatment efficiency due to the aforementioned problems, but nothing has been presented as an specific alternative to treat the fly ash in a large quantity while securing safety and durability.

Method for Power Supply
If the first and second heating members 311 and 312 of the quantum energy generator 310 are wound in opposite directions to each other to form a solenoid coil shape and the DC power generated from the DC power suppliers 311a and 312a is supplied thereto, the heating members may generate heat while magnetic fields are generated at an angle of 90 degrees with respect to a direction of current flow. Then, heating may be carried out at 500° C. or higher so that the surfaces of the heating members 311 and 312 and the first and second negative electrodes 321 and 322 may receive energy enough to overcome a work function of a material (metal) and thus to discharge thermal electrons from the surfaces thereof. Further, the surfaces of the first and second negative electrodes 321 and 322 are to be sufficiently heated at 500° C. or higher so that the unburned pulverized coal out of the fly ash coming into contact with the surfaces may be heated at an ignition point (500° C. or higher) or higher to cause a combustion reaction, in which such unburned pulverized coal is naturally burned under an oxygen atmosphere (oxygen in aid contained in the fly ash).
The first negative electrode 321 may receive power from the DC power supplier 321a and the second negative electrode 322 may receive power from the DC power supplier 322a.
A + terminal at an output side of the DC power supplier 321a may be connected to the first negative electrode 321, a − terminal at an output side thereof may be connected to a − terminal at an output side of the DC power supplier 311a for the first heating member 311, a + terminal at an output side of the DC power supplier 322a may be connected to the second negative electrode 322, and a − terminal at an output side thereof may be connected to a − terminal at an output side of the DC power supplier 312a for the second heating member 312, so that the thermal electrons discharged by heating at a high temperature the surfaces of the first and second heating members 311 and 312 of the quantum energy generator 310 may be accelerated toward the first and second negative electrodes 321 and 322 by electrical attraction.
Further, to increase an accelerating force of the thermal electrons discharged from the first and second heating members 311 and 312, a voltage at an output side of the DC power suppliers 321a and 322a for the first and second negative electrodes 321 and 322 is to be increased by an amount of voltage selected from a range of 1 to 10 KV compared to an output voltage of the DC power suppliers 311a and 312a for the first and second heating members 311 and 312 of the quantum energy generator 310.
The surfaces of the first and second heating members 311 and 312 of the quantum energy generator 310 are to be heated at a high temperature so that the thermal electrons discharged therefrom are added and accelerated with an increase in electrical attraction as much as an amount of a potential difference supplied to the first and second negative electrodes 321 and 322 and the thermal electrons may be discharged from the surfaces of the negative electrodes 321 and 322 in a collision process with the first negative electrode 321 and the second negative electrode 322, respectively. The surfaces of the first and second negative electrodes 321 and 322 are to be heated at 500° C. or higher so that the unburned pulverized coal out of the fly ash coming into contact with the surfaces may be naturally burned under an oxygen atmosphere (oxygen or ionized oxygen ions in air contained in the fly ash) and may be removed while generating carbon monoxide (CO) or carbon dioxide (CO2) through a combustion reaction.
Further, the first positive electrode 331 may receive power from the DC power supplier 331a and the second positive electrode 332 may receive power from the DC power supplier 332a.
A + terminal at an output side of the DC power supplier 331a may be connected to the first positive electrode 331, a − terminal at an output side thereof may be connected to a − terminal at an output side of the DC power supplier 321a for the first heating member 321, a + terminal at an output side of the DC power supplier 332a may be connected to the second positive electrode 332, and a − terminal at an output side thereof may be connected to a − terminal at an output side of the DC power supplier 322a for the second negative electrode 322, so that the thermal electrons discharged from the surfaces of the first negative electrode 311 and the second negative electrode 312 may be accelerated in a direction of the first and second positive electrodes 331 and 332 by electrical attraction.
Further, to increase an accelerating force of the thermal electrons discharged from the first and second negative electrodes 321 and 322 by electrical attraction, a voltage at an output side of the DC power suppliers 331a and 332a for the first and second positive electrodes 331 and 332 is to be increased as much as an amount of voltage selected from a range of 1 to 10 KV compared to an output voltage of the DC power suppliers 321a and 322a for the first and second negative electrodes.
In addition, the thermal electrons, which are discharged from the surfaces of the first and second negative electrodes 321 and 322 due to a potential difference between the DC power suppliers 321a and 331a and between the DC power suppliers 322a and 332a, may be accelerated in a direction of the first and second positive electrodes 331 and 332 as much as an amount of electrical attraction increased, thereby increasing an intensity of elastic collisions with the fly ash particles passing through a fluid passage formed between the first negative electrode 321 and the first positive electrode 331 and between the second negative electrode 322 and the second positive electrode 332, so that it may become more easier to remove main components of the glassy membrane coated on the surface of the fly ash particles, which include materials such as silica, or silicon dioxide (SiO2), sodium oxide (Na2O), calcium oxide (CaO), potassium oxide (K2O) and zinc oxide (ZnO), magnesium oxide (MgO), barium oxide (BaO), alumina (Al2O3), etc.
Furthermore, each magnetic field generated in a direction of 90 degrees with respect to a direction of current flow caused by the current flow of the first and second heating members 311 and 312 of the quantum energy generator 310, which are wound in opposite directions to each other, may extend retention time of thermal electrons discharged from the surface of the first negative electrode 321 and accelerated toward the first positive electrode 331, may extend retention time of thermal electrons discharged from the surface of the second negative electrode 322 and may be accelerated toward the second positive electrode 332, and may increase a number of elastic collisions with the fly ash particles passing through a fluid passage formed between the first negative electrode 321 and the first positive electrode 331 and between the second negative electrode 322 and the second positive electrode 332, thereby improving a rate of removing a glassy membrane from the surface of the fly ash particles, so that the magnetic fields generated from the first and second heating members 311 and 312 of the quantum energy generator 310 may be overlapped and extinguished, and quantum energy generated in a zero magnetic field state may be irradiated to activate thermal electrons, thereby further improving the rate of removing a glassy membrane from the surface of the fly ash.
An amount of the thermal electrons discharged may be increased as the negative electrodes 321 and 322 are heated at a higher temperature, as a current density is increased, and as a material of the negative electrodes 321 and 322 includes a metal having a less work function energy.
Thus, a material of the negative electrodes 321 and 322 used in the present invention may include at least one selected from molybdenum (Mo: 4.36-4.93 eV), titanium (Ti: 4.33 eV), tungsten (W: 4.32-5.22 eV), manganese (Mn: 4.1 eV), carbon compound (C: 5.0 eV) and compounds such as iron (Fe: 4.67-4.81 eV), etc., which have a less value of the work function (electron volt: eV).
If DC power is supplied from the DC power suppliers 311a and 312a to the first and second heating members 311 and 312 of the quantum energy generator 310, pre-wound in opposite directions to each other, while the fly ash remained after filtering out the fly ash particles having a particle size of 50 μm or more as well as impurities through a granularity separator (not shown) is transported through a feeder 200 to a fluid passage formed between the first negative electrode 321 and the first positive electrode 331 and between the second negative electrode 322 and the second positive electrode 332, which are installed at one side of the inside of the housing 301, a magnetic field may be generated in a direction of 90 degrees with respect to current flow to heat the first heating member 311, so that thermal electrons may be discharged from the surface thereof. Then, when a potential difference is given between the DC power supplier 311a for the first heating member 311 and the DC power supplier 321a for the first negative electrode 321, and when a potential difference is given between the DC power supplier 321a for the first negative electrode 321 and the DC power supplier 331a for the first positive electrode 331, the thermal electrons discharged from the surface of the first heating member 311 may be accelerated in a direction of the first negative electrode 321, while the thermal electrons generated from the surface of the first negative electrode 321 may be accelerated in a direction of the first positive electrode 331, thereby hitting the fly ash particles containing air, when passing through a fluid passage formed between the first negative electrode 321 and the first positive electrode 331. Then, the constituent molecules of air in the fly ash particles, which include oxygen molecule (O2), vapor (H2O), nitrogen molecule (N2) and sulfur oxide (SOX), may be dissociated to generate oxygen ion (O), hydrogen proton (H+), hydroxyl ion (OH−) and nitrogen ion (N), remove sulfur oxide (SOX) and nitrogen oxide (NOX) through an oxidation and reduction reaction with the generated oxygen ion (0) and hydrogen proton (H+), so that the unburned pulverized coal out of the fly ash may come into contact with the surfaces of the negative electrodes 321 and 322 heated at 500° C. or higher and may be heated at 500° C., which is an ignition point of carbon (C), or higher, and naturally burned under an oxygen atmosphere (oxygen in air contained in the fly ash) to generate carbon monoxide (CO) or carbon dioxide (CO2) through a combustion reaction, thereby primarily removing the unburned pulverized coal, and combustion reaction formulas thereof are as shown in the following formulas 1, 2 and 3.

Further, carbon dioxide (CO2) generated from removing the unburned pulverized coal out of the fly ash particles through the combustion reaction above may be allowed to react with main components of the glassy membrane coated on the fly ash particles, which include calcium oxide (CaO), sodium oxide (Na2O), magnesium oxide (MgO), potassium oxide (K2O) and barium oxide (BaO), in a process of elastic collision between the fly ash particles and the thermal electrons discharged from the surfaces of the negative electrodes 321 and 322 heated, thereby generating carbonates such as calcium carbonate (CaCO3), sodium carbonate (Na2CO3), magnesium carbonate (MgCO3), potassium carbonate (K2CO3), barium carbonate (BaCO3), etc., so as to primarily remove the glassy membrane coated on the fly ash particles, and the chemical reaction formulas thereof are as shown in the following reaction formulas 1, 2, 3, 4 and 5.

As shown above, the carbonates may be generated to remove the glassy membrane, but a main component of the glassy membrane, which includes silicon dioxide (SiO2), may react with carbon at a high temperature of 1700° C. or higher, and thus may not be removed in the thermal decomposition part.
Further, to improve an efficiency of treating the fly ash, at least one selected from catalytic materials such as barium oxide (BaO), strontium oxide (SrO), calcium oxide (CaO), etc. may be applied to promote the release of thermal electrons from the surfaces of the negative electrodes 321 and 322 at a high temperature.
At least one selected from titanium dioxide (TiO2), rhodium (Rh), platinum (Pt), palladium (Pd), ruthenium (Ru), zinc (Zn), zirconium (Zr), hafnium (Hf), vanadium (V2O5), niobium, tungsten (W), iron (Fe), ruthenium oxide (RuO2 and RuO4), rhodium oxide (Rh2O3), copper oxide (CuO), zinc oxide (ZnO), zirconium oxide (ZrO2), silicon dioxide (SiO2), titanium oxide (TiO2), hafnium oxide (HfO2), aluminum oxide (Al2O3), vanadium oxide (VO and V2O3), niobium oxide (Nb2O5), tungsten oxide (WO), manganese (Mn) and iron oxide (FeO) may be applied on the surfaces of the first and second positive electrodes 331 and 332, thereby improving an efficiency of treating materials such as carbon monoxide (CO), nitrogen oxide (NOx), sulfur oxide (SOC), etc., which are already contained in the fly ash or are generated during a treatment process.
Further, a magnetic field generated by a flow of current in the second heating member 321 of the quantum energy generator 310, which is wound by the same method, may accelerate by electrical attraction the thermal electrons discharged from the surface heated at a high temperature in a direction of the second negative electrode 322, and may accelerate by electrical attraction the thermal electrons generated from the surface of the second negative electrode 322 in a direction of the second positive electrode 332, thereby hitting the fly ash particles passing through a fluid passage formed between the second negative electrode 322 and the second positive electrode 332.
In general, the thermal electrons generated from the first and second heating members 311 and 312 and the first and second negative electrodes may be subject to Lorentz Force (F) caused by distribution of an electric field vector (E) and a magnetic field vector (B) as shown in the following Equation 1.
F=q(E+v×B) [Equation 1]
Here, v is a velocity vector of a thermal electron.
At that time, a thermal electron having a very small mass has a very small radius of rotation caused by Lorentz Force, and thus comes to move “along with a magnetic line of force” and this phenomenon is called a magnetic confinement of an electron.
Further, the first heating member 321 and the second heating member 322 may be wound in opposite directions to each other, so that the directions of current flowing to the heating members 321 and 322 may be formed opposite to each other and magnetic fields generated according to the current flow may be disposed to work in opposite directions to each other, and thus the magnetic fields may be overlapped and canceled out at the center of the inside of the housing 301, that is, at an area where the first and second positive electrodes 331 and 332 of the fluid passage may be installed to come into surface contact with each other. In this case, an overall magnetic field may become zero. In fact, however, subtle energy (hereinafter, SE) may occur.
This SE is called Scalar energy, Non-Hertzian or the like as quantum energy, but is commonly called quantum energy.
The quantum energy generated as above may act as an additional energy source to activate thermal electrons and promote a dissociation action of gas-phase materials out of the fly ash, thereby improving an efficiency of treating the fly ash.
Further, the sources of the DC power supply 311a and 312a, which supply power to the first and second heating members 311 and 312 of the quantum energy generator 310, may refer to the first and second DC power suppliers 311a and 312a having a function of controlling the current of power supply therein, which may be one selected from a single-phase voltage source inverter (MPCC: model predictive current control) or a DC-DC converter, which is a combination of a PWM (pulse width modulation) control mode and a PFM (pulse frequency modulation) mode. If DC power is supplied from the first and second DC power suppliers 311a and 312a to the first and second heating members 311 and 312, the heating members 311 and 312 may generate heat to heat the first negative electrode 321 and the second negative electrode 322, which are installed to be spaced apart from each other, at an absolute temperature of 500° C. or higher, thereby discharging thermal electrons from the surfaces thereof. A set temperature may be adjusted through a control circuit input in a pre-programmed control panel 600 and a heating value of the heating members may be adjusted by controlling a current of DC power supplied to DC power suppliers 311a and 312a as shown in [Equation 2].
H=0.24 I2Rt [Equation 2]
Here, H is calory (Kcal/h), I is current (A), R is resistance of a conductor (ohm), and t is a current carrying time (Sec).
Further, an intensity of magnetic field (magnetic flux density) may be adjusted as shown in [Equation 3].

Here, B is an intensity of magnetic field, k is a magnetic constant (K=2×10−6 Tm/A), T is a number of coil windings, and I is current.
Further, an intensity of Lorentz Force may be adjusted as shown in [Equation 4].
F=BIl [Equation 4]
Here, F is Lorentz Force, I is current, and l is a length of coil.
Further, the intensity of magnetic field may be used to adjust an amount of quantum energy generated at a zero-magnetic field state in which magnetic fields are overlapped between the first heating member 311 and the second heating member 312.

When a high voltage generated from the high-voltage generator 413 may be applied to the discharge electrode 411 and the ground electrode 412 through the conducting wire 414 to start discharge between the two electrodes 411 and 412, a gap control may be performed by using a gap-adjusting device (not shown).
Further, coating may be performed with a least one selected from catalytic materials for promoting release of thermal electrons from the surfaces of the discharge electrode 411 and the ground electrode 412, such as barium oxide (BaO), strontium oxide (SrO), calcium oxide (CaO), etc., and mixed with at least one selected from titanium dioxide (TiO2), rhodium (Rh), platinum (Pt), palladium (Pd), ruthenium (Ru), zinc (Zn), zirconium (Zr), hafnium, vanadium (V2O5), niobium, tungsten (W), iron (Fe), ruthenium oxide (RuO2 and RuO4), rhodium oxide (Rh2O3), copper oxide (CuO), zinc oxide (ZnO), zirconium oxide (ZrO2), silicon dioxide (SiO2), titanium oxide (TiO2), hafnium oxide (HfO2), aluminum oxide (Al2O3), vanadium oxide (VO and V2O3), niobium oxide (Nb2O5), tungsten oxide (WO), manganese (Mn) and iron oxide (FeO), which remove materials such as nitrogen oxide (NOx), sulfur oxide (SOx), volatile organic compounds (VOCS), etc.
If the control panel 600 supplies power to the driving motor 416, the driving motor 416 may be rotated, so that the discharge electrode 411 and the ground electrode 412 may be rotated to engage with each other while being spaced apart from each other. The air pressurized from the air feeder 440 may be sprayed through the spray nozzle 446 onto the discharge electrode 411 and the ground electrode 412 which are rotated to form an air void between the fly ash particles while being mixed with the fly ash particles introduced between the two electrodes 411 and 412. If power is supplied from the power suppliers 421a and 422a to the first heating member 421 and the second heating member 421 of the quantum energy generation unit 420 installed inside the discharge electrode 411 and the ground electrode 412 while being insulated from each other, a magnetic field may be formed at an angle of 90 degrees with respect to a direction of current flow to generate heat, so that thermal energy may be transferred in a thermal conductive manner. If a high voltage generated from the high-voltage generator 413 is applied to the discharge electrode 411 and the ground electrode 412 while heating the discharge electrode 411 and the ground electrode 412 at 500° C. or higher, discharge may be started between the two electrodes 411 and 412 to form an electric field-electron energy (5 eV-5 KeV) band, which is larger than 5.0 eV, which is a value of work function of silicon dioxide (SiO2), 1.6 eV, which is a value of work function of calcium oxide (CaO), 4.7 eV, a value of work function of magnesium oxide (MgO), and 5.0 eV, which is a value of work function of alumina (Al2O3), which are the main components of the glassy membrane out of the fly ash.
Thus, the glassy membrane covering the surface of the ash particles may be removed through at least on electrochemical reaction out of dissociation, excitation, oxidation and reduction in a discharge process during a process of elastic collision between fly ash particles and charged particles including electrons, ions or the like, and thermal electrons discharged from the surfaces of the two electrodes, and the magnetic fields generated by a current flow to the first heating member 421 and the second heating member of the quantum energy generation unit 420 may extend retention time of thermal electrons and increase a number of elastic collisions between fly ash particles and thermal electrons to improve an efficiency of removing the glassy membrane.
In a state in which the thermal electrons are discharged from the surfaces of the two electrodes 411 and 412 heated at a high temperature, the fly ash with the unburned pulverized coal primarily treated in the thermal decomposition part 300 may be introduced between the two electrodes 411 and 412, which are rotated in opposite directions to each other, then come into contact with the surfaces of the two electrodes 411 and 412, then heated at 500° C., which is an ignition temperature of the unburned pulverized coal, or higher, and then naturally burned under an oxygen atmosphere (oxygen or ionized oxygen ions in air contained in the fly ash), so that the unburned pulverized coal may be removed while generating carbon monoxide (CO) or carbon dioxide (CO) through the combustion process. Alternatively, the combustion reaction may be progressed by spark or flame generated during the discharge operation between the discharge electrode 421 and the ground electrode 422, so that the unburned pulverized coal may be removed while generating carbon monoxide (CO) or carbon dioxide (CO2).

In addition, if power is supplied from the first power supplier 421a and the second power supplier 422a to the first and second coils 421 and 422 of the quantum energy generator 420, a magnetic field may be generated at an angle of 90 degrees with respect to a direction of current flowing in each coil due to coils 421 and 422, which are wound in opposite directions to each other. For example, a magnetic field generated from the first coil 421 may be formed in a direction of the second coil 422 and a magnetic field generated from the second coil 422 may be formed in a direction of the first coil 421. Thus, a magnetic field generated from each of the coils 421 and 422 at a center distance between the first coil 421 and the second coil 422, which is seemingly up to a center distance between the discharge electrode 411 and the ground electrode 412, may extend retention time of thermal electrons and electric charges discharged from the surfaces of the two electrodes 411 and 412 in a high electric field energy band formed during a discharge process in the two electrodes 411 and 412, thereby increasing a number of elastic collisions between the fly ash particles passing through a fluid passage formed between the discharge electrode 411 and the ground electrode 412 and charged particles including electrons, ions or the like, and thermal electrons, which are generated from the discharge process of the two electrodes 411 and 412, so as to improve a rate of removing the glassy membrane coated on the fly ash particles. Then, magnetic fields generated from the first coil 421 and the second coil 422 at a center distance between the discharge electrode 411 and the ground electrode 412 are overlapped and extinguished, so that the quantum energy generated in a zero energy state may be irradiated to activate the thermal electrons discharged from the surfaces of the two electrodes 411 and 412, and the charged particles including the electrons, ions or the like, thereby further improving an efficiency of treating the fly ash.
Further, the sources of the power supply 421a and 322a, which supply power to the first and second heating members 421 and 422 of the quantum energy generator 420, may refer to the first and second power suppliers 421a and 422a having a function of controlling the current of power supply therein, which may be one selected from a single-phase voltage source inverter (MPCC: model predictive current control) or a DC-DC converter, which is a combination of a PWM (pulse width modulation) control mode and a PFM (pulse frequency modulation) mode. If power is supplied from the first and second power suppliers 421a and 422a to the first and second heating members 421 and 422, the first and second heating members 411 and 412 generate heat to heat the discharge electrode 421 and the ground electrode 422, which are installed to be spaced apart from each other, at a temperature of 500° C. or higher, thereby discharging thermal electrons from the surfaces thereof. A set temperature may be adjusted through a control circuit input in a pre-programmed control panel 600 and a heating value of the heating members may be adjusted by controlling a current of power supplied to power suppliers 411a and 412a as shown in [Equation 5].

Further, the intensity of magnetic field may be used to adjust an amount of quantum energy generated at a zero-magnetic field state in which magnetic fields are overlapped between the first heating member 411 and the second heating member 412.
In addition, a heating value of the first and second coils 421 and 422 of the quantum energy generator 420 may be adjusted to heat the surfaces of the discharge electrode 411 and the ground electrode 412 of the high-voltage discharge unit 410, which are installed to come into surface contact with the first and second coils 421 and 422 outside while being insulated from each other, at 500° C., which is an ignition point of the unburned carbon out of the fly ash, or higher, so that the unburned carbon may be heated at 500° C., which is an ignition temperature, or higher, while passing in contact with the two electrodes 411 and 412, and naturally burned under an oxygen atmosphere and the unburned pulverized coal may be removed while generating carbon monoxide (CO) or carbon dioxide (CO) through the combustion reaction. Alternatively, the unburned pulverized coal may be removed in such a way that the combustion reaction is progressed by spark or flame generated between the discharge electrode (421) and the ground electrode (422) during the discharge operation while generating carbon monoxide (CO) or carbon dioxide (CO2), or the unburned pulverized coal may be removed at the same time due to the combustion reaction caused by a natural ignition under an oxygen atmosphere and the combustion reaction by an ignition source generated by a discharge reaction.
If the control panel 600 supplies AC or DC power to the first coil 421 and the second coil 422 of the quantum energy generator 420, which are wound by a plurality of winding times in opposite directions to each other, Lorentz Force may work in a direction of magnetic field and current flow, which are opposite directions to each other at an angle of 90 degrees to current flow, and the first coil 421 and the second coil 412 may generate heat to heat the discharge electrode and the ground electrode, which are installed at a certain interval up to a temperature input in a control circuit of the pre-programmed control panel.
If the discharge electrode unit 410 is heated up to a set temperature, the driving motor 416 may be driven by receiving power from the control panel 600, and then a high voltage generated from the high-voltage generator 413 may be applied to the discharge electrode 411 and the ground electrode 412 to start an arch discharge between the two electrodes, thereby forming a high electric field energy band.
Further, the high-voltage discharge may be performed through arch discharge, corona discharge, glow discharge and spatter discharge, preferably arc discharge.
The arc discharge may refer to a state of weakly ionized plasma including electrons, ions or neutral gas atoms, and most of the particles are neutral gas atoms including the same number of electrons and ions. In plasma, electrons are relatively lighter than other particles, and thus move at a fast speed in an electric field, thereby obtaining a large amount of energy per unit time, and thus those electrons transfer energy in an elastic or inelastic collision form with other particles. Due to the elastic collision, particles may obtain energy and thus a temperature thereof is raised, while particles may be ionized and excited to a higher energy level due to the inelastic collision. This phenomenon is called the phenomenon of continuity and luminescence of arc discharge.
A phenomenon of line broadening may refer to a case in which a gas particle moving in a plasma state causes a deformation in a radiation spectrum in inelastic collision with disturbing particles. In this case, a profile of radiant rays may be determined depending on a frequency of collisions, a density and velocity of particles, etc. As a distance from a surrounding atom is decreased, a degree of disturbance thereof may become larger. In a high-voltage discharge arc, a main line broadening may occur due to collision broadening caused by disturbing of transition energy levels caused by direct collision between a light source, an excited atom and other disturbing particles. Types of collision broadening may be classified into stark line broadening caused by collision with charged particles including electrons, ions or the like, resonance line broadening, which is caused in case a colliding particle is a particle such as an excited particle, and Van der Waals line broadening caused by collision with other types of neutral atoms.
If this collision broadening is caused by collision between atoms, such collision broadening may be dependent on a pressure of gas, and line broadening caused by collision with charged particles may be dependent on input current.
Plasma may be generated in such a way that electrons are accelerated by a high electric field to ionize molecules of gas. Energy for ionization may be called breakdown voltage and may amount to 5 eV-5 KeV in air. Radicals excited at a high energy state without being ionized may be generated a lot in plasma, thus causing various chemical reactions.

Arch discharge may have a feature in that a voltage is decreased and current is increased when starting discharge unlike glow discharge or corona discharge, particularly in that thermal electrons are discharged from the surfaces of the two electrodes 411 and 412 as a role of the negative electrodes through heating of the two electrodes 411 and 412.
The electrons may obtain energy while moving at a high speed within the arc discharge area, and may transfer energy by causing an elastic collision with other particles. At that time, a temperature of particles may be increased, and particles may become ionized and excited to a high energy level through an inelastic collision, thus causing arch discharge continuously.
Further, during the occurrence of arch discharge, electrons and thermal electrons may move between the two electrodes 411 and 412 at a fast speed and the particles having obtained a large amount of energy per unit time may be subject to elastic collision so as to obtain energy. At that time, high-temperature heat may occur. This temperature thereof may amount to about 3,000 to 6,000° C. Further, the particles may be ionized and excited to an energy level in an inelastic collision, which occurs after an elastic collision, and light (flame) may be generated in the process of resolving excitation.
The first and second coils 421 and 422, which are wound in opposite directions to each other, may be installed inside the discharge electrode 411 and the ground electrode 412, and then the first and second coils 421 and 422 may generate heat to heat the discharge electrode 411 and the ground electrode 412, thereby promoting the release of thermal electrons from the electrodes. Then, a magnetic field may be applied to confine the thermal electrons in a discharge area, thereby extending retention time thereof, increasing a number of elastic collisions with fly ash particles passing through the discharge area, dissociating gas-phase materials such as oxygen (O2), nitrogen (N2), vapor molecule (H2O) and sulfur oxide (SOX), which form air contained in the fly ash, so as to remove air pollutants contained in the fly ash through an oxidation and reduction reaction with the generated oxygen ion (O), nitrogen ion (N), hydrogen proton (H+), hydroxyl ion (OH−), sulfur oxide (SOX) and nitrogen oxide (NOX).
Further, in a process of elastic collision between fly ash particles and charged particles including electrons, ions or the like, and thermal electrons, which are discharged from the two electrodes 411 and 412 through the generation of a field-electron energy (IE, eV), which is larger than a value of work function of the main components of the glassy membrane covering the surface of fly ash in the two electrodes 411 and 412 heated at a high temperature in a high electric field area, which includes 5.0 eV for silicon dioxide (SiO2), 1.6 eV for calcium oxide (CaO), 4.7 eV for magnesium oxide (MgO), 1.1 eV for barium oxide (BaO), and 5.0 eV for alumina (Al2O3),

To that end, with regard to a voltage at the input and output sides of the power supplier 412a for the discharge electrode 411 and the ground electrode 412, it is required that a field-electron energy (1E, eV) capable of cleaving a covalent bonding of oxygen molecule (O2) is 12.0857 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of water molecule is 12.621 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of hydrogen molecule (H2) is 15.4259 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of sulfur dioxide (SO2) is 12.349 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of sulfur trioxide (SO3) is 12.8 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of nitrogen oxide (NO) is 9.2542 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of nitrogen dioxide (NO2) is 9.586 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of nitrous oxide (N2O) is 12.889 eV or more, a field-electron energy (1E, eV) capable of cleaving a covalent bonding of carbon monoxide (CO) is 14.014 eV or more, and a field-electron energy (1E, eV) capable of cleaving a covalent bonding of carbon dioxide (CO) is 13.777 eV or more. After the molecules are dissociated, it is necessary to have a dissociation energy for cleaving an inter-atomic covalent bonding, which includes 414 KJ/mol or more for C—H bonding, 389 KJ/mol or more for N—H bonding, 348 KJ/mol or more for O—H bonding, 163 KJ/mol or more for N—N bonding, 146 KJ/mol or more for O—O bonding, 253 KJ/mol or more for Cl—F bonding, 293 KJ/mol or more for C—N bonding, 201 KJ/mol or more for N—O bonding, 190 KJ/mol or more for O—F bonding, 242 KJ/mol or more for Cl—Cl bonding, 351 KJ/mol or more for C—O bonding, 272 KJ/mol or more for N—F bonding, 611 KJ/mol or more for C═C bonding, 837 KJ/mol or more for C═C bonding, 615 KJ/mol or more for C═N bonding, and 799 KJ/mol or more for C═O bonding.

In case of A.C and D.C voltages, a voltage at an output side may be appropriately selected from a range of 1 KV to 500 KV considering field conditions and throughputs. In case of A.C voltage, a frequency may be appropriately selected from a range of 60 to 50 KHz considering field conditions and throughtputs.

A material of the brush for the dedusting unit 430 may include any material which is not deformed in an environment of high temperature and is wear resistant, and may include a material which is available in the market.
A revolution per minute of the dedubsting units 431a and 431b may be the one selected from a range of 50 to 300 RPM.
Further, an anti-dust plate 403 extending from one side of the housing 401 may be installed at a lower part of the brush 431 for the dedusting unit 430 to collect dust eliminated from the brush and discharge the collected dust to a discharge port.

The fly ash discharged after being finally treated in the electrochemical reaction part 400 may be temporarily stored in the hopper 501. If the motor 506 is driven while feeding the air compressed by the blower 503 to the discharge pipe 504 at the same time, and if the motor-operated valve 502 installed at the lower part of the hopper 501 is open while driving the screw 505 in the discharge pipe 504 connected to a shaft of the motor 506, the fly ash fed into the hopper 501 may be fed into the discharge pipe 504. If the motor 506 is driven along with the compressed air fed from the blower 503, the screw 505 connected to a shaft of the motor may be rotated. If the fly ash introduced in the discharge pipe 504 is fed into the storage tank 506, the fly ash floating in the tank 507 by an air pressurized introduced from the blower 503 may be collected in a filter medium of a filtered dust collector 508, and then exhausted into the air.
