[0002] In the current energy field, hydrogen, as a clean and efficient energy carrier, has attracted much attention because it produces almost no pollutants during its combustion process. The combustion reaction of hydrogen has high energy density and fast reaction rate, and is suitable for a variety of industrial applications. However, traditional hydrogen combustion methods usually rely on open flames, which not only poses potential safety hazards, such as fire and explosion risks, but also in some application scenarios, open flame combustion is difficult to achieve precise temperature control and energy release regulation. To this end, another method is provided in the current energy field, that is, hydrogen is converted into electrical energy through a fuel cell, and the electrical energy is then converted into thermal energy through an electric heater. However, this method converts hydrogen energy into electrical energy and then into thermal energy. During the multiple conversions, the high loss leads to low conversion efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, Figure 1 It is a structural schematic diagram of a hydrogen fireless combustion system provided by an embodiment of the present invention, and the hydrogen fireless combustion system includes: an air volume module, a flow module 2, a pipeline 3, a first hydrogen sensor 4, a hydrogen combustion reaction module 5, a temperature sensor 6, a second hydrogen sensor 7, and a control module 9. The air volume module includes a fan 1 and an air volume control module 8.

[0035] The air volume module is used to deliver air to the hydrogen combustion reaction module 5. Specifically, the air can be delivered to the hydrogen combustion reaction module 5 by the fan 1, and the air volume control module 8 controls the amount of air delivered by the fan 1 to the hydrogen combustion reaction module 5.

[0036] The flow module 2 is used to control the flow rate of hydrogen delivered to the hydrogen combustion reaction module 5. The flow module 2 can be any device capable of controlling the flow rate of hydrogen, such as an electronically controlled mass flow controller (MFC, Mass Flow Controller), an electronic proportional flow control valve (Electronic Proportional Flow Control Valve) and the like.

[0037] The pipeline 3 is used to transmit the air and hydrogen transmitted by the fan 1, and output the high-temperature air to the outside when the hydrogen combustion reaction module outputs the high-temperature air.

[0038] The first hydrogen sensor 4 is used to detect the hydrogen content in the hydrogen combustion reaction module 5 and act on the adjustment of the flow module 2;

[0039] The second hydrogen sensor 7 is used to detect the hydrogen content in the high-temperature air output by the hydrogen combustion reaction module 5, and acts on the adjustment of the flow module 2; the first hydrogen sensor 4 and the second hydrogen sensor 7 can use the same sensor or different types of hydrogen sensors, which can be selected according to actual needs. For example, it can be an electrochemical hydrogen sensor, a thermal conductivity hydrogen sensor (Thermal Conductivity Sensor), a semiconductor hydrogen sensor (Semiconductor-based Sensor), a catalytic combustion hydrogen sensor (CatalyticCombustion Sensor), an optical hydrogen sensor (Optical Hydrogen Sensor), a solid-state battery hydrogen sensor (Solid State Battery Sensor) and any other hydrogen sensor.

[0040] The temperature sensor 6 is used to detect the preheating temperature in the hydrogen combustion reaction module 5 and acts on the start-up of the flow module 2 and the air volume module. The temperature sensor 6 can be any temperature sensor capable of high temperature detection, such as a thermocouple sensor (Thermocouple), a platinum resistance temperature detector (RTD, Resistance Temperature Detector), an infrared temperature sensor (Infrared Thermometer / Pyrometer), an optical fiber temperature sensor (Fiber Optic Temperature Sensor) and the like. Specifically, the thermocouple sensor can be a K-type thermocouple (nickel-chromium-nickel-silicon), a J-type thermocouple (iron-copper-nickel), an R-type and S-type thermocouple (platinum-platinum-rhodium), etc. The infrared temperature sensor can be a short-wave infrared sensor or a long-wave infrared sensor, which can be selected according to actual needs.

[0041] The above-mentioned hydrogen combustion reaction module 5 is used to combine hydrogen with oxygen in the air under the action of the above-mentioned flameless combustion catalytic substance to release heat and water. The above-mentioned hydrogen combustion reaction module can be a closed space constructed of materials such as stainless steel, ceramics, quartz glass, etc., and realizes flameless combustion of hydrogen in the above-mentioned closed space. The above-mentioned hydrogen combustion reaction module may have an air inlet and an air outlet. The above-mentioned air inlet is used to input hydrogen and air into the hydrogen combustion reaction module, and the above-mentioned air outlet is used to output high-temperature air.

[0042] The control module 9 is used to control the entire hydrogen fireless combustion system. The control module 9 can be constructed by any control chip, for example, it can be any one of an MCU chip (such as STM32, ESP32, ATmega, etc.), a DSP chip (such as TMS320 series), an FPGA chip (such as Xilinx Spartan series, Intel Cyclone series), a PLC controller (such as Siemens S7 series, Allen-Bradley series), a PID control chip (such as AD5933), etc.

[0043] Specifically, the control module 9 is connected to the flow module 2 , the first hydrogen sensor 4 , the hydrogen combustion reaction module 5 , the temperature sensor 6 , and the second hydrogen sensor 7 , respectively.

[0044] The above-mentioned control module 9 is also connected to the controlled end of the above-mentioned air volume control module 8, and is used to send an air volume control instruction to the above-mentioned air volume control module 8 to adjust the air volume to the hydrogen combustion reaction module. The control end of the above-mentioned air volume control module 8 is connected to the above-mentioned fan 1, and is used to adjust the air volume output by the above-mentioned fan according to the above-mentioned air volume control instruction.

[0045] like Figure 2 As shown, Figure 2 1 is a flow chart of a method for hydrogen combustion without fire provided by an embodiment of the present invention, comprising:

[0046] 201. When the preheating temperature of the hydrogen combustion reaction module reaches the preheating temperature range, a start instruction is sent to the air volume module and the flow module, so that the air volume module injects air into the hydrogen combustion reaction module, and the flow module injects hydrogen into the hydrogen combustion reaction module.

[0047] In an embodiment of the present invention, the above-mentioned hydrogen fireless combustion method can be applied to the above-mentioned hydrogen fireless combustion system, and specifically can be applied to the control module of the above-mentioned hydrogen fireless combustion system. After the above-mentioned hydrogen fireless combustion system is started, if the control module does not find that the system is abnormal (that is, the system operates normally), the hydrogen combustion reaction module will be powered on for preheating. During the above-mentioned preheating process, the preheating temperature in the above-mentioned hydrogen combustion reaction module can be continuously detected by the above-mentioned temperature sensor until the above-mentioned preheating temperature reaches the above-mentioned preheating temperature range, and a start-up instruction is sent to the air volume module and the flow module. After receiving the above-mentioned start-up instruction, the above-mentioned air volume module and the above-mentioned flow module can continuously inject air and air into the above-mentioned hydrogen combustion reaction module.

[0048] Specifically, the preheating temperature range may be 180 degrees Celsius to 250 degrees Celsius. Within the preheating temperature range, the fireless combustion catalytic substance can react better with hydrogen to improve the thermal energy conversion efficiency of hydrogen fireless combustion.

[0049] It should be noted that after the power is turned on for preheating and the preheating temperature is reached, there is no need to turn on the power for preheating again, because during the process of the reaction between the fireless catalytic combustion material and the hydrogen, both are in a hot state.

[0050] 202. When the flow module injects hydrogen into the hydrogen combustion reaction module, the hydrogen content in the hydrogen combustion reaction module is continuously detected, and the flow module is adjusted based on the hydrogen content until the hydrogen content reaches the target content value, and then the adjustment is stopped.

[0051] In the embodiment of the present invention, when the flow module injects hydrogen into the hydrogen combustion reaction module, hydrogen and air will be mixed in the pipeline of the hydrogen fireless combustion system, so the hydrogen content can be detected in the pipeline at the air inlet of the hydrogen combustion reaction module, and specifically, the first hydrogen sensor can be used to continuously detect the hydrogen content in the pipeline at the air inlet of the hydrogen combustion reaction module. The flow module is adjusted according to the hydrogen content until the hydrogen content reaches the target content value, and the adjustment is stopped.

[0052] Specifically, the target content value may be 4%. When the hydrogen content accounts for 4% of the total air ratio, the fireless combustion catalytic substance can react better with hydrogen to improve the thermal energy conversion efficiency of hydrogen fireless combustion.

[0053] More specifically, when the hydrogen content is greater than the target content, the hydrogen flow rate input to the flow module can be adjusted downward, and when the hydrogen content is less than the target content, the hydrogen flow rate input to the flow module can be adjusted upward.

[0054] 203. When the oxygen content reaches the target content value, a preset fireless combustion catalytic substance is injected into the hydrogen combustion reaction module so that the fireless combustion catalytic substance catalyzes the hydrogen in the hydrogen combustion reaction module to achieve fireless combustion of hydrogen.

[0055] In an embodiment of the present invention, the above-mentioned flameless combustion catalytic substance can be a complex containing platinum metal, palladium metal and aluminum oxide, specifically Pt-Pd / AlxOx. When the hydrogen content reaches the target content value, Pt-Pd / AlxOx can be injected into the hydrogen combustion reaction module. Under the action of Pt-Pd / AlxOx, hydrogen combines with oxygen in the air to release a large amount of heat and water. During the entire reaction process, hydrogen only acts as a catalytic reaction and will not burn with an open flame. The high-temperature heat heats the air, and the water is evaporated into water vapor by the high temperature.

[0056] Specifically, the injection of the above-mentioned fireless combustion catalytic substance can be done manually, or a catalytic substance injection module can be set up separately to inject the fireless combustion catalytic substance into the hydrogen combustion reaction module when the target content value is reached.

[0057] Alternatively, the above-mentioned flameless combustion catalytic substance may be pre-installed in the above-mentioned hydrogen combustion reaction module, and the above-mentioned hydrogen flameless combustion may be achieved by opening and closing the air inlet of the above-mentioned hydrogen combustion reaction module. Specifically, when the hydrogen content at the above-mentioned air inlet reaches the above-mentioned target content value, the above-mentioned air inlet may be opened to allow the mixed gas to enter the above-mentioned hydrogen combustion reaction module and react with the pre-installed flameless combustion catalytic substance to achieve the above-mentioned hydrogen flameless combustion. Conversely, when the hydrogen content at the above-mentioned air inlet does not meet the above-mentioned target content value, the above-mentioned air inlet may be closed.

[0058] Under the action of the above-mentioned flameless combustion catalytic substance, the above-mentioned hydrogen combustion reaction module can output high-temperature air with a temperature exceeding 300 degrees Celsius through the pipe at the air outlet. It can achieve efficient heat energy conversion. By accurately controlling the preheating temperature and gas flow, efficient flameless combustion of hydrogen is achieved. The control of the preheating temperature ensures the optimal activity of the catalyst, and the precise injection of hydrogen and air ensures the stability and efficiency of the combustion process. The automated control of the overall system reduces the complexity of manual operation and improves the reliability and safety of the combustion process.

[0059] In an embodiment of the present invention, when the preheating temperature of the hydrogen combustion reaction module reaches the preheating temperature range, a start instruction is sent to the air volume module and the flow module, so that the air volume module injects air into the hydrogen combustion reaction module, and the flow module injects hydrogen into the hydrogen combustion reaction module; when the flow module injects hydrogen into the hydrogen combustion reaction module, the hydrogen content in the hydrogen combustion reaction module is continuously detected, and the flow module is adjusted based on the hydrogen content until the hydrogen content reaches the target content value, and the adjustment is stopped; when the oxygen content reaches the target content value, a preset fireless combustion catalytic substance is injected into the hydrogen combustion reaction module, so that the fireless combustion catalytic substance catalyzes the hydrogen in the hydrogen combustion reaction module to achieve the fireless combustion of hydrogen. When the preheating temperature of the hydrogen combustion reaction module reaches the preheating temperature range, the flow module and the air volume module are started, so that air and hydrogen are injected into the hydrogen combustion reaction module, and when the hydrogen content reaches the target content value, the fireless combustion catalytic substance is injected into the hydrogen combustion reaction module, so as to achieve the fireless combustion of hydrogen. By precisely controlling the preheating temperature, the injection flow of air and hydrogen, and real-time monitoring and adjustment of the hydrogen content, an efficient and stable fireless combustion process can be achieved to improve the safety and conversion efficiency of the hydrogen energy to heat energy process.

[0060] It is understandable that in the specific implementation of the present application, related data such as startup instructions and temperature control adjustment instructions are involved. When the embodiments in the present application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data and the collection, use and processing of energy such as hydrogen need to comply with relevant laws, regulations and standards of relevant countries and regions.

[0061] It should be noted that the hydrogen fireless combustion method provided in the embodiment of the present invention can be applied to computers, servers and other equipment that can perform hydrogen fireless combustion.

[0062] Optionally, after the step of allowing the flameless combustion catalytic substance to catalyze the hydrogen in the hydrogen combustion reaction module to achieve the flameless combustion of the hydrogen, the high-temperature air generated by the hydrogen combustion reaction module during the hydrogen flameless combustion process can also be detected; when there is hydrogen content in the high-temperature air, the flow module is adjusted until the adjustment is stopped when there is no hydrogen content in the high-temperature air.

[0063] In an embodiment of the present invention, after the fireless combustion catalytic substance in the hydrogen combustion reaction module catalytically reacts with hydrogen, high-temperature air will be output to the gas outlet of the hydrogen combustion reaction module. At this time, the high-temperature air generated at the above-mentioned gas outlet can be detected by the above-mentioned second hydrogen sensor. When there is hydrogen content in the high-temperature air, the flow module is adjusted until the adjustment is stopped when there is no hydrogen content in the high-temperature air. Under normal circumstances, when there is hydrogen content in the high-temperature air, it means that the hydrogen has not been completely reacted. At this time, it is usually caused by the high hydrogen content at the air inlet. Therefore, the hydrogen flow rate delivered by the above-mentioned flow module to the above-mentioned hydrogen combustion reaction module can be lowered. The complete combustion of hydrogen in the high-temperature air is ensured by the monitoring of the second hydrogen sensor and the automatic adjustment of the flow module. Not only the combustion efficiency is improved, the emission of unburned hydrogen is reduced, and the environmental protection performance is improved, but also the waste of hydrogen is avoided, and the economy and safety of the hydrogen fireless combustion system are enhanced.

[0064] Optionally, after the flameless combustion catalytic substance catalyzes the hydrogen in the hydrogen combustion reaction module to achieve the flameless combustion of the hydrogen, when a temperature control adjustment instruction is received, a temperature control adjustment ratio can be determined based on the temperature control adjustment instruction; and the flow module and the air volume module can be adjusted simultaneously based on the temperature control adjustment ratio so that the hydrogen combustion reaction module outputs a temperature corresponding to the temperature control adjustment instruction.

[0065] In an embodiment of the present invention, the temperature control adjustment instruction may include a target temperature. Assuming that in the default state, the high-temperature air output by the hydrogen combustion reaction module is 300 degrees Celsius, which cannot meet the actual use requirement of 350 degrees Celsius, the 350 degrees Celsius can be used as the target temperature, and the temperature control adjustment instruction is generated. The temperature control adjustment instruction is provided to the control module. After receiving the temperature control adjustment instruction, the control module can determine the temperature control adjustment ratio according to the temperature control adjustment instruction, and adjust the flow module and the air volume module at the same time according to the temperature control adjustment ratio.

[0066] It should be noted that since the adjustment of the above-mentioned flow module and the above-mentioned air volume module is adjusted simultaneously through the above-mentioned temperature control adjustment ratio, after the adjustment, it can still be ensured that the hydrogen content meets the target content value. At the same time, due to the increase in hydrogen flow and air flow, the temperature of the above-mentioned high-temperature air can be increased accordingly.

[0067] Furthermore, if the temperature of the high-temperature air needs to be lowered, the corresponding temperature adjustment ratio can also be calculated, and the hydrogen flow rate and the air flow rate can be simultaneously lowered according to the temperature adjustment ratio based on the flow module and the air volume module.

[0068] It is understandable that the response of the temperature control adjustment command and the synchronous adjustment of the flow and air volume modules enable the hydrogen fireless combustion system to flexibly respond to different temperature requirements and ensure that the combustion process is carried out at the optimal temperature. Through the improvement of flexibility, the adaptability and versatility of the hydrogen fireless combustion system are further improved, meeting the combustion requirements in different application scenarios, and enhancing the practicality and market competitiveness of the hydrogen fireless combustion system.

[0069] Optionally, the hydrogen fireless combustion system also includes a first hydrogen sensor, a second hydrogen sensor and a temperature sensor; the first hydrogen sensor is used to detect the hydrogen content in the hydrogen combustion reaction module, and acts on the adjustment of the flow module; the second hydrogen sensor is used to detect the hydrogen content in the high-temperature air output by the hydrogen combustion reaction module, and acts on the adjustment of the flow module; the temperature sensor is used to detect the preheating temperature in the hydrogen combustion reaction module, and acts on the startup of the flow module and the air volume module.

[0070] In an embodiment of the present invention, the hydrogen fireless combustion system used in the hydrogen fireless combustion method may further include a first hydrogen sensor, a second hydrogen sensor and a temperature sensor. The temperature sensor may be any temperature sensor capable of high temperature detection, such as a thermocouple sensor (Thermocouple), a platinum resistance temperature detector (RTD, Resistance Temperature Detector), an infrared temperature sensor (Infrared Thermometer / Pyrometer), an optical fiber temperature sensor (Fiber Optic Temperature Sensor) and the like. Specifically, the thermocouple sensor may be a K-type thermocouple (nickel-chromium-nickel-silicon), a J-type thermocouple (iron-copper-nickel), an R-type and an S-type thermocouple (platinum-platinum-rhodium), etc. The infrared temperature sensor may be a short-wave infrared sensor or a long-wave infrared sensor, which may be selected according to actual needs.

[0071] The first hydrogen sensor and the second hydrogen sensor may be the same sensor or different types of hydrogen sensors, which may be selected according to actual needs. For example, they may be any hydrogen sensor such as an electrochemical hydrogen sensor, a thermal conductivity hydrogen sensor, a semiconductor-based sensor, a catalytic combustion hydrogen sensor, an optical hydrogen sensor, or a solid state battery hydrogen sensor.
