A first partial flow (f11) of the H2-air-steam mixture (f1) is passed through a first channel (R) and recombined by contact with a first channel wall (r1) having a catalytic coating. In addition to the first partial flow (f11), a second partial flow (f12) of the said mixture is passed through a second channel (z) having a second channel wall (r2) and, in that case, is ignited by being fed past, preferably metallic, ignition elements (z, z1, z2, z3) heated to the H2 ignition temperature on reaching or exceeding the ignition limit. Under these circumstances, the heat liberated during the catalytic reaction in the first channel (R) is, at least partially, transmitted to the second channel (z) 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 H2 concentrations. - A device with which the process can be carried out is also described.
