Problems solved by technology

However, in the actual use process, the fuel-air ratio of hydrogen is low, and most of the heat generated by hydrogen catalytic combustion will be taken out by the exhaust flow. Therefore, there are technologies that cannot effectively use the heat in the exhaust flow and improve the efficiency of the hydrogen catalytic burner as much as possible. question

Description

technical field [0001] The invention belongs to the technical field of hydrogen catalytic combustion, and in particular relates to a direct exhaust hydrogen catalytic combustion heat supply device. Background technique [0002] At present, energy is the most important element in human economic activities, and is closely related to the survival and development of human society. With the increase of fossil fuel consumption, its reserves are decreasing day by day, and the resources are facing the problem of depletion. Hydrogen is a clean energy source, which can be used to generate electricity through fuel cells (FC) or hydrogen internal combustion engines (ICEs), or directly burned to generate heat for heating. The use of hydrogen combustion to obtain heat energy is an important way in the process of hydrogen energy utilization. The combustion of hydrogen is divided into flame combustion and catalytic flameless combustion. Flameless catalytic combustion using hydrogen has t...
