The present invention relates to a method and a device with fuel for combustion that is used in the sectors of industry, canteen and power plant, in particular, relates to an energy-saving, efficient and environment- friendly fuel-combustion method and device.
Currently, for the existing fuel burners, during the operation, the fuel is sent by a pipe to the furnace (or devices), which is ignited and then directly burns in the furnace. The common defect of such fuel burners is: more than 50% of the valuable fuel has not yet reached the complete combustion before being discharged to the living space, which contains the thermal radiation, carbon dioxide, nitrogen dioxide, carbon monoxide, nitrogen oxides and sulfides etc. that form the main cause of acid rain, resulting in the leading culprit, blamed for the damages to the human living environment, or even the root that endangers the human life. Therefore, the author has designed many utilities, which have been granted with the patents, including patent No. ZL200520144552.6 as a utility model with the title “an energy-saving fuel burner”, patent No. ZL200620012784.0 as a utility model with the title “an energy-saving fuel burner”, patent No. ZL200620137252.X as a utility model with the title “a fuel heat flow generator”, and patent No. ZL200620157779.9 as a utility model with the title “fuel liquid phase converter”, intended to solve the aforesaid problems, but they are not perfect.
The object of the present invention: as a more complete solution to all of the aforesaid burner defects, the present invention provides an energy-saving complete combustion method and the relevant burner.
A fuel-combustion energy-saving method, characterized in that: the combustion method is:
1> An input port lets the fuel enter into the furnace, where the fuel is ignited to bring forth the incomplete combustion:
2> Another input port is used for adding the supplementary fuel to the furnace, which is mixed with the early-coming fuel in the furnace that is burning to bring forth the complete combustion;
3> The burning fuel experiences the phenomenon of cracking, gasification and expansion, but it is restrained in the furnace for compression, resulting in the fusion reaction for the purpose of perfect combustion;
4> Synchronized with the above steps, the air taken from the furnace side wall is mixed with the burning fuel in the furnace, which makes the heat generated in the furnace is erupted due to the combustion.
An embodiment of claim/method of the non-thermal-radiation fuel burner, comprising a furnace configured with a hearth inside that consists of a shell with multiple through-holes, while the hearth contains the primary combustion chamber, secondary combustion chamber and blocking chamber; and the primary combustion chamber is divided into the lower/upper shells or multiple shells, between which there are through-holes as the connection channel; the shells are distributed with plural through holes, which form the channel that connects the secondary combustion chamber; the secondary combustion chamber is a compartment formed by the hearth and the shell of the primary combustion chamber and separation plate with plural through-holes on the shell; the blocking chamber consists of the sealing plate of the furnace and the separation plate, while the sealing plate is provided with the flame holes which are relevant to the air flow holes provided in the separation plate and sealing plate, and while the air flow holes connects the secondary combustion chamber and the blocking chamber.
Said hearth is provided with two input ports, one connects the low end of primary combustion chamber, and the other connects the low end of the secondary combustion chamber.
Said primary combustion chamber is provided with an igniter inside.
There is an air channel between the said furnace and hearth.
Said the lower shell of the primary combustion chamber (21) consists of two or more support legs.
Said support legs are provided with multiple through holes.
The beneficial effects of present invention
Two fuel ejection ports are used for the present invention, one input port allows to sustain the ignition point and temperature in the furnace after the fuel is fed and ignited, meanwhile, it allows the fuel fed through the other fuel input cracked more rapidly and split instantly, resulting in more complete combustion of the fuel. The present invention is mainly composed of the primary combustion chamber, secondary combustion chamber and blocking chamber, allowing the fuel combustion in the furnace to bring forth continuous repeatedly cracking, differentiation, gasification, expansion and compression, so the fuel molecules experience fusion reaction to release the inherent energy completely; with the complete combustion, the hot flame is generated, which however will not release thermal radiation, but reduces the generation of various harmful gases.
A fuel-combustion energy-saving method, where the combustion method is:
1> An input port lets the fuel enter into the furnace, where the fuel is ignited to bring forth the incomplete combustion:
2> Another input port is used for adding the supplementary fuel to the furnace, which is mixed with the early-coming fuel in the furnace that is burning to bring forth the complete combustion;
3> The burning fuel experiences the phenomenon of cracking, gasification and expansion, but it is restrained in the furnace for compression, resulting in the fusion reaction for the purpose of perfect combustion;
4> Synchronized with the above steps, the air taken from the furnace side wall is mixed with the burning fuel in the furnace, which makes the heat generated in the furnace is erupted due to the combustion.
An embodiment of above method of the non-thermal-radiation fuel burner is shown in
The lower shell of the primary combustion chamber 21 consists of two or more support legs 212 that are provided with plural through-holes 51.
The following is a more detailed description in combination with the non-thermal-radiation fuel burner and the principle.
During the operation, fuel is sent in the primary combustion chamber 21 through the input port 9, and the igniter 10 is activated, then the flame maintains the basic combustion temperature and ignition point in the combustion chamber to bring forth the preliminary incomplete burning, so that the fuel in the combustion chamber experiences continuous cracking and gasification; at the same time, oil is supplemented to the secondary combustion chamber 22 through another input port 9, which is heated by the flame due to the fuel burning in the primary combustion chamber 21, and is mixed with the air taken from the air flow through-holes 8 in the sealing plate 7, so the fuel experiences instantaneously cracking and gasification to bring forth the intermediate complete combustion; then the fuel enters the blocking chamber 23; since the sealing plate 7 of the blocking chamber 23 is provided only with the flame holes 71 that allows the flame flows out the furnace body 1, the fuel cannot erupt out the furnace body 1 instantly, but blocked in the furnace body 1, so the fuel that is burning in the furnace body experiences further continuous repeated gasification, compression, and cracking to produce more thorough fusion, so that the inherent energy of the fuel ingredients is converted into thermal energy and then released, and so there is no radiation to carry out the energy from the bright flame, which achieves advanced and perfect combustion. Finally, the flame erupts from the flame holes in the sealing plate 7 of the blocking chamber 23, so the erupted flame carries with only the high temperature, while the radiation is thoroughly eliminated—if the hand is placed near the flame, it still feels cool without being scalded.
It is informative from above description, the non-thermal-radiation fuel burner allows more perfect and complete combustion, which is unlikely to extinguish even at the small feeding rate of 20 mlS/min under the enclosed condition. The releasable temperature is as high as 1350° C. The energy consumption rate is 50% lower than the similar devices, or even better, while the emission of harmful gases is greatly reduced, which even can simplify the gas catalytic transformation procedure to allow a clean heat recovery.
