Abstract

The invention discloses a self-heating type hydrogen-oxygen catalytic burner and a self-heating start method. The self-heating type hydrogen-oxygen catalytic burner comprises a gas mixing chamber, anair pipeline and a hydrogen pipeline, wherein the air pipeline and the hydrogen pipeline are perpendicularly arranged in the gas mixing chamber. An air pipeline fire barrier and a hydrogen pipeline fire barrier are arranged in the air pipeline and the hydrogen pipeline correspondingly, a cellular catalytic burning chamber rolled by a catalytic plate is arranged below the gas mixing chamber, and agas distributor is connected between the gas mixing chamber and the catalytic burning chamber. The hydrogen-oxygen catalytic burner is applicable to heating, safe and reliable, the self-heating function is particularly applicable to field application, mixed gas is introduced in according to the ratio of hydrogen to nitrogen being 2:3-3:2, the temperature can reach 160 DEG C or above after 3-6min,and self-heating start is achieved; and when hydrogen reacts with air, the hydrogen volume ratio is controlled to be 10% or below, combustion tail gas with different temperatures is obtained by controlling the mixed gas flow and the hydrogen volume ratio so as to be used for different heating occasions.

Description

technical field [0001] The invention belongs to the field of hydrogen energy application, in particular to a self-heating hydrogen-oxygen catalytic burner and its self-heating starting method. Background technique [0002] Hydrogen has the advantages of green and pollution-free, high mass energy density, renewable, and abundant resources. It is considered as a green energy in the 21st century and has great application potential. Researches on the production, storage, transportation and application of hydrogen are in full swing around the world, in order to gain an advantage in the future technology field and new energy competition. [0003] Heating is one of the important applications of hydrogen. However, hydrogen combustion has the disadvantages of fast combustion, high temperature, easy tempering, and great safety hazards. Therefore, hydrogen combustion for heating has not been widely promoted. The complete combustion of hydrogen and oxygen at a lower temperature under t...
