DETAILED DESCRIPTION

Aspects and implementations of the present disclosure are directed to a flameless heater system. Flameless heaters are used to provide heat in harsh and potentially hazardous environments, such as oil fields or grain drying. Flameless heaters operate in environments that include volatile gasses that may be ignited by an ignition source, such as a spark or an open flame. The use of flameless heaters in such environments reduce the risk of explosions or uncontrolled fires by providing heat without the use of an ignition source.

One example of a flameless heater system utilizes an internal combustion engine to drive a fluid based heat generator. The heat generator shears a fluid, causing the fluid to heat. The heated fluid is then circulated through hoses using an engine-driven pump to a storage tank. The heated fluid is then transferred from the storage tank to a fluid-to-air heat exchanger, where the heat is extracted from the heated fluid. Another example of a flameless heater system utilizes an internal combustion engine to drive a fan while moving magnets to create heat.

However, the delay between the startup of a conventional flameless heater and the ability to produce full capacity heated air flow is considerable. At the time of startup, the engine block and fluids are cold, and time is needed to warm the engine block and engine fluids to operating temperatures. Furthermore, while the engine block and fluids are warming, an air mover is distributing air from the heater assembly, effectively cooling the engine block. Also, without having the ability to regulate the flow of hydraulic fluid, more time is needed for the fluid to reach operational conditions. Accordingly, a conventional flameless heater system that takes a considerable amount of time to reach operating temperatures may not be suitable for time dependent heating purposes.

Embodiments of the present disclosure address the issues of conventional flameless heater systems by implementing systems and controls to reduce the time needed to generate heated air produced by a flameless heater system. By utilizing an independent heating system, thermal energy may be produced from converting energy provided by an energy source. The use of an independent air system allows for the flow of to be controlled to hamper the air's ability to cool the engine block before operating temperatures are reached. The use of an independent hydraulic system allows the flow of hydraulic fluid to be controlled to lessen the fluid's ability to cool the engine block before operating temperatures are reached. Additionally, by using both an independent speed system and an independent braking system, engine loading may be controlled to adjust the engine's power output. The use of an independent temperature system allows temperatures in various locations of the flameless heater system to be controlled to local, remote, and telemetry-based user parameters. The result is an improved flameless heater system that generates heat, improving the performance of the flameless heater system, and allows the flameless heater system to be used in various processes, where a conventional flameless heater system may take too long to adequately preform its function.

In embodiments, flameless heaters may be placed in different operating conditions that require the same air flow rate but at a much different static pressures. The control system can adjust the rotational speed of a fan to achieve the same airflow over a range of static pressures by increasing or reducing the output of a hydraulic motor. Thus once the user selects the desired air temperature for the heater outlet air, the control system can maintain that temperature despite a host of changes in operating conditions, such as inlet air temperature, static pressure demand, fuel burn rate, etc., further improving the performance of the flameless heater system.

FIG. 6 depicts a flow diagram of a method 600 for controlling a flameless heater system in accordance with implementations of the present disclosure. In embodiments, various portions of method 600 may be performed by control system 190 of FIGS. 1-2.

With reference to FIG. 6, method 600 illustrates example functions used by various embodiments. Although specific function blocks (“blocks”) are disclosed in method 600, such blocks are examples. That is, embodiments are well suited to performing various other blocks or variations of the blocks recited in method 600. It is appreciated that the blocks in method 600 may be performed in an order different than presented, and that not all of the blocks in method 600 may be performed.

At block 610, a control system (e.g., processing device 802) receives parameters (e.g., temperatures, velocities, pressures, distances, engine RPM, fuel burn rate, etc.) associated with a flameless heater. In embodiments, the control system may receive the temperature from one or more temperature sensors of a flameless heater system. In an embodiment, the temperature may correspond to a temperature of a volume of space that is being heated by the flameless heater system. For example, the temperature may correspond to the temperature of a room being heated by the flameless heater system. In some embodiments, the control system may receive the velocity from one or more air sensors of the flameless heater system. In embodiments, the velocity may correspond to a speed of the volume of space that is being targeted by the flameless heater system. In some embodiments, the control system may receive the velocity from one or more hydraulic sensors of the flameless heater system. In embodiments, the velocity may correspond to a speed of the fluid that is being targeted by the flameless heater system. In an embodiment, the control system may receive the velocity from one or more speed sensors of the flameless heater system. In embodiments, the velocity may correspond to a speed of rotating structure that is being targeted by the flameless heater system. In some embodiments, the control system may receive the engine power output from one or more braking sensors of the flameless heater system. In embodiments, the power output may correspond to the engine fuel burn rate that is being targeted by the flameless heater system.

At block 620, the control system determines if the parameters received at block 610 satisfy a threshold. In embodiments, one threshold may correspond to a temperature value. In embodiments, the temperature may satisfy the threshold if the temperature is greater than or equal to the threshold. For example, if the threshold is 72 degrees and the temperature received at block 610 is 75 degrees, then the temperature satisfies the threshold. In some embodiments, the temperature may satisfy the threshold if the temperature is less than or equal to the threshold. For example, if the threshold is 72 degrees and the temperature received at block 610 is 68 degrees, then the temperature satisfies the threshold. In an embodiment, multiple thresholds may be used to create a range of temperatures. For example, a first threshold may be used that specifies a temperature less than or equal to 65 degrees satisfies the first threshold and a second threshold may be used that specifies a temperature greater than or equal to 75 degrees satisfies the second threshold. Accordingly, if the received temperature is outside of the specified temperature range (e.g., is less than or equal to 65 degrees or greater than or equal to 75 degrees), then the temperature satisfies the threshold.

In some embodiments, another threshold may correspond to a velocity value. In embodiments, the velocity may satisfy the threshold if the velocity is less than or equal to the threshold. In an embodiment, the velocity may satisfy the threshold if the velocity is greater than or equal to the threshold. For example, if the threshold is not to exceed 5 feet per second and the velocity received at block 610 is 2 feet per second, then the velocity satisfies the threshold. In some embodiments, the velocity may satisfy the threshold if the temperature is greater than or equal to the threshold. For example, if the threshold is 10 feet per second and the velocity received at block 610 is 12 feet per second, then the temperature satisfies the threshold. In an embodiment, multiple thresholds may be used to create a range of velocities. For example, a first threshold may be used that specifies a velocity less than or equal to 3 feet per second satisfies the first threshold and a second threshold may be used that specifies a velocity greater than or equal to 15 feet per second satisfies the second threshold. Accordingly, if the received velocity is outside of the specified velocity range (e.g., is less than or equal to 3 feet per second or greater than or equal to 15 feet per second), then the velocity satisfies the threshold.

In some embodiments, another threshold may correspond to an engine loading value. In embodiments, the engine loading value may satisfy the threshold if the braking system's output is less than or equal to the threshold. In an embodiment, the engine loading value may satisfy the threshold if it is less than or equal to the threshold. For example, if the threshold is not to exceed a set distance measured between the pivoting magnet arm and the rotating structure and distance received is less than the threshold, then the loading value satisfies the threshold resulting in less breaking output and greater engine loading. In some embodiments, the loading value may satisfy the threshold if the distance is greater than or equal to the threshold. For example, if the threshold is to exceed a set distance measured between the pivoting magnet arm and the rotating structure and distance received is greater than the threshold, then the loading value satisfies the threshold resulting in more breaking output and less engine loading. In an embodiment, multiple thresholds may be used to create a range of loading values. For example, a first threshold may be used that specifies a distance measured between the pivoting magnet arm and the rotating structure satisfies the first threshold and a second threshold may be used that specifies a larger distance measured between the pivoting magnet arm and the rotating structure satisfies the second threshold. Accordingly, if the received loading value is outside of the specified distance range (e.g., is less than one distance or greater than or equal to a larger distance), then the engine loading satisfies the threshold.

In some embodiments, multiple thresholds may be used for other parameters. For example, the control system may utilize a temperature threshold corresponding to a temperature value and a velocity threshold corresponding to a velocity value. In embodiments, the threshold may be provided via a user interface of the control system. In some embodiments, the threshold may be provided via a temperature regulating device, such as a thermostat.

In embodiments, other thresholds may correspond to a pressure, an engine RPM, or a fuel burn rate value. If the temperature, velocity, pressure, engine RPM, and fuel burn rate satisfy their respective thresholds, at block 630 the control system adjusts the heat output of a heating system and/or the velocity output of an air, hydraulic, speed system and/or the engine power output of a breaking system of the flameless heater system. For example, if the temperature received at block 610 is too high (e.g., is greater than the threshold at block 620), then the control system may decrease the heat output of the heating system or choose to modify the engine power output through the braking system. In another example, if the temperature received at block 610 is too low (e.g., is less than the threshold at block 620), then the control system may increase the heat output of the heating system. The control system would also have the option to support the increase in heat output by reducing one or more fan speeds, controlled by the air system, or reducing the flow of hydraulic fluid, controlled by the hydraulic system.

In embodiments, if the velocity of hydraulic fluid is too high, then the control system may determine to decrease the velocity output of the hydraulic system by opening, closing, or throttling one or more valves within the flameless heater system. In another embodiment, if the velocity of hydraulic fluid is too low, then the control system may determine to increase the velocity output of the hydraulic system by activating one or more pumps within the flameless heater system. In embodiments, if the velocity of air is too high, then the control system may determine to decrease the velocity output of the air system by reducing the speed of one or more fans within the flameless heater system. In some embodiments, the one or more fan speeds may be reduced to zero. In another embodiment, if the velocity of air is too low, then the control system may determine to increase the velocity output of the air system by activating one or more fans within the flameless heater system.

If the control system determines the temperature, velocity, pressure, engine RPM, and/or fuel burn rate do not satisfy their respective thresholds, at block 640 the control system determines to not adjust parameters associated with the respective systems of the flameless heater system.

FIG. 7 is a block diagram that illustrates an example of a telematics system 700, in accordance with an embodiment of the present disclosure. The telematics system 700 may include a control system 710 of a flameless heater system 100, as previously described with respect to FIGS. 1-4. The control system 710 includes a processing device 720 that executes a telematics component 729. In embodiments, the control system 710 may be operatively coupled to a data store 730 and a client device 750 via a network 740. In some embodiments, the data store 730 may reside in the control system 710.

The network 740 may be a public network (e.g., the internet), a private network (e.g., a local area network (LAN) or wide area network (WAN)), or a combination thereof. In one embodiment, network 740 may include a wired or a wireless infrastructure, which may be provided by one or more wireless communications systems, such as a wireless fidelity (WiFi) hotspot connected with the network 740 and/or a wireless carrier system that can be implemented using various data processing equipment, communication towers (e.g. cell towers), etc.

The client device 750 may be a computing device, such as a personal computer, laptop, cellular phone, personal digital assistant (PDA), gaming console, tablet, etc. In embodiments, the client device 750 may be associated with a technician for the flameless heater system 100.

The data store 730 may be a persistent storage that is capable of storing data (e.g., parameters associated with a flameless heater system 100, as described herein). A persistent storage may be a local storage unit or a remote storage unit. Persistent storage may be a magnetic storage unit, optical storage unit, solid state storage unit, electronic storage units (main memory), or similar storage unit. Persistent storage may also be a monolithic/single device or a distributed set of devices.

In embodiments, data store 730 may be a central server or a cloud-based storage system including a processing device (not shown). The central server or the cloud-based storage system may be accessed by control system 710 and/or client device 750. Parameters from the flameless heater system 100 may be transmitted to the data store 730 for storage. In embodiments, upon receipt of the parameters, the data store 730 may transmit the parameters to client device 750. In some embodiments, the parameters stored at the data store may be accessed by client device 750 via a user interface. For example, the data store 730 may generate a graphical user interface (GUI) to present the parameters of the flameless heater system 100 to client device 750. In embodiments, client device 750 may provide adjustments to one or more parameters of the flameless heater system 100 to the data store 730. In some embodiments, upon receipt of the adjustments, the data store 730 may transmit the adjustments to the parameters to control system 710. In some embodiments, the adjustments to the parameters may be accessed by control system 710 via a user interface.

In embodiments, telematics component 729 may transmit parameters of a flameless heater system to client device 750. Telematics component 729 may receive, from client device 750, one or more adjustments to one or more parameters of the flameless heater system.

FIG. 8 illustrates a diagrammatic representation of a machine in the example form of a computer system 800 within which a set of instructions, for causing the machine to perform any one or more of the methodologies discussed herein, may be executed. In alternative embodiments, the machine may be connected (e.g., networked) to other machines in a local area network (LAN), an intranet, an extranet, or the Internet. The machine may operate in the capacity of a server or a client machine in a client-server network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a personal computer (PC), a tablet PC, a web appliance, a server, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein. In one embodiment, computer system 800 may be representative of a server configured to control the operations of flameless heater system 100.

The exemplary computer system 800 includes a processing device 802, a user interface display 813, a main memory 804 (e.g., read-only memory (ROM), flash memory, dynamic random access memory (DRAM)), a static memory 806 (e.g., flash memory, static random access memory (SRAM), etc.), and a data storage device 818, which communicate with each other via a bus 830. Any of the signals provided over various buses described herein may be time multiplexed with other signals and provided over one or more common buses. Additionally, the interconnection between circuit components or blocks may be shown as buses or as single signal lines. Each of the buses may alternatively be one or more single signal lines and each of the single signal lines may alternatively be buses.

Processing device 802 represents one or more general-purpose processing devices such as a microprocessor, central processing unit, or the like. More particularly, the processing device may be complex instruction set computing (CISC) microprocessor, reduced instruction set computer (RISC) microprocessor, very long instruction word (VLIW) microprocessor, or processor implementing other instruction sets, or processors implementing a combination of instruction sets. Processing device 802 may also be one or more special-purpose processing devices such as an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a digital signal processor (DSP), network processor, or the like. The processing device 802 is configured to execute processing logic 826, which may be one example of system 100 as shown in FIG. 1, for performing the operations and blocks discussed herein.

The data storage device 818 may include a machine-readable storage medium 828, on which is stored one or more set of instructions 822 (e.g., software) embodying any one or more of the methodologies of functions described herein, including instructions to cause the processing device 802 to execute a control system (e.g., control system 160). The instructions 822 may also reside, completely or at least partially, within the main memory 804 or within the processing device 802 during execution thereof by the computer system 800; the main memory 804 and the processing device 802 also constitute machine-readable storage media. The instructions 822 may further be transmitted or received over a network 820 via the network interface device 808.

The machine-readable storage medium 828 may also be used to store instructions to perform a method for device identification, as described herein. While the machine-readable storage medium 828 is shown in an exemplary embodiment to be a single medium, the term “machine-readable storage medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) that store the one or more sets of instructions. A machine-readable medium includes any mechanism for storing information in a form (e.g., software, processing application) readable by a machine (e.g., a computer). The machine-readable medium may include, but is not limited to, magnetic storage medium (e.g., floppy diskette); optical storage medium (e.g., CD-ROM); magneto-optical storage medium; read-only memory (ROM); random-access memory (RAM); erasable programmable memory (e.g., EPROM and EEPROM); flash memory; or another type of medium suitable for storing electronic instructions.

The preceding description sets forth numerous specific details such as examples of specific systems, components, methods, and so forth, in order to provide a good understanding of several embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that at least some embodiments of the present disclosure may be practiced without these specific details. In other instances, well-known components or methods are not described in detail or are presented in simple block diagram format in order to avoid unnecessarily obscuring the present disclosure. Thus, the specific details set forth are merely exemplary. Particular embodiments may vary from these exemplary details and still be contemplated to be within the scope of the present disclosure.

Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiments included in at least one embodiment. Thus, the appearances of the phrase “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”.

Additionally, some embodiments may be practiced in distributed computing environments where the machine-readable medium is stored on and or executed by more than one computer system. In addition, the information transferred between computer systems may either be pulled or pushed across the communication medium connecting the computer systems.

Embodiments of the claimed subject matter include, but are not limited to, various operations described herein. These operations may be performed by hardware components, software, firmware, or a combination thereof.

Although the operations of the methods herein are shown and described in a particular order, the order of the operations of each method may be altered so that certain operations may be performed in an inverse order or so that certain operation may be performed, at least in part, concurrently with other operations. In another embodiment, instructions or sub-operations of distinct operations may be in an intermittent or alternating manner.

The above description of illustrated implementations of the invention, including what is described in the Abstract, is not intended to be exhaustive or to limit the invention to the precise forms disclosed. While specific implementations of, and examples for, the invention are described herein for illustrative purposes, various equivalent modifications are possible within the scope of the invention, as those skilled in the relevant art will recognize. The words “example” or “exemplary” are used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the words “example” or “exemplary” is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X includes A or B” is intended to mean any of the natural inclusive permutations. That is, if X includes A; X includes B; or X includes both A and B, then “X includes A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. Moreover, use of the term “an embodiment” or “one embodiment” or “an implementation” or “one implementation” throughout is not intended to mean the same embodiment or implementation unless described as such. Furthermore, the terms “first,” “second,” “third,” “fourth,” etc. as used herein are meant as labels to distinguish among different elements and may not necessarily have an ordinal meaning according to their numerical designation.
