ABSTRACT:
A first partial flow of an H.sub.2 -air-steam mixture is passed through a first channel and recombined by contact with a first channel wall having a catalytic coating. In addition to the first partial flow, a second partial flow of the mixture is passed through a second channel having a second channel wall and is ignited by being fed past preferably metallic ignition elements being heated to the H.sub.2 ignition temperature upon reaching or exceeding an ignition limit. Under these circumstances, heat liberated during the catalytic reaction in the first channel is at least partially transmitted to the second channel for the purpose of preheating it. The novel process functions both at the lower and at the upper ignition limit and recombines even at unignitable H.sub.2 concentrations. A device with which the process can be carried out is also described.
