The internal temperature field of the hydrogen-oxygen recombination reactor has a uniform temperature distribution while avoiding local hot spots.

Description

technical field [0001] The invention relates to the field of hydrogen energy application, in particular to a hydrogen-oxygen composite reactor. Background technique [0002] Heating is one of the important applications of hydrogen. However, hydrogen has an extremely wide explosion limit of 4.0-75vol%, a flame speed of 2.7m / s, and a flame temperature close to 2000°C. Therefore, hydrogen combustion has a wide combustion range, fast combustion speed, and extremely high temperature. High temperature, easy tempering, and high potential safety hazards, so hydrogen combustion heating has not been widely promoted. In 1974, Sharer et al. discovered that hydrogen and oxygen could react completely on the surface of the catalyst at room temperature and release heat. This reaction is called hydrogen-oxygen recombination reaction, which has the characteristics of low temperature and no flame. [0003] There are many studies on the principle of hydrogen-oxygen recombination reaction, and ...
