Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of heating devices, and in particular relates to a heating device based on hydrogen catalytic combustion technology and a use method thereof. Background Art
[0002] Hydrogen is considered an ideal energy source due to its high energy density and low carbon emission characteristics. Hydrogen does not directly produce pollutants such as carbon dioxide, sulfur dioxide and smoke during combustion, so it has been widely used in the preparation of chemical raw materials, mobile travel, power generation, and industrial and household heating.
[0003] As a way of energy utilization, direct combustion of hydrogen has the advantages of being clean and environmentally friendly, but it also has some disadvantages and shortcomings: (1) Safety: Hydrogen is highly flammable and explosive. When mixed with air, it may burn or explode within a concentration range of 4% to 75%. The direct combustion and explosion range of hydrogen is relatively wide, and the flame of hydrogen combustion is difficult to observe. It is light blue and almost invisible in daylight, which increases the difficulty of monitoring and responding to fires.
[0004] (2) Heat utilization efficiency: Hydrogen burns quickly, and its flame propagation speed is 7.72 times that of gasoline. This may lead to local high-temperature areas and local oxygen-rich areas in the combustion chamber, making the reaction heat control strategy extremely complex and difficult to implement. The heat generated by hydrogen flame combustion is concentrated and easily produces local high temperatures, resulting in low heat utilization efficiency.
[0005] (3) Hydrogen flashback: When hydrogen burns, the flame propagation speed is relatively fast, which greatly increases the risk of flashback in premixed combustion. The main factor causing flashback is that the flame propagation speed in the boundary layer exceeds the incoming flow speed. This requires accurate prediction of boundary layer flashback during the design phase, which makes research and development difficult and difficult to implement.
[0006] (4) Nitrogen oxide emissions: The only pollutant generated by hydrogen combustion is thermal NO x The main factors affecting its generation are the combustion zone temperature, oxygen concentration and combustion residence time. Flame combustion will inevitably produce local high temperature areas and local oxygen over-concentration areas, which are very important for inhibiting thermal NO x The generation of is extremely unfavorable.
