In the catalytic combustion of H2 and O2 in a recombination reactor, the gases are fed alternately to the reactor via inlet valves which are designed such that they always open at one internal pressure P1 of the reactor, but close at different internal pressure p2/H<2> or p2/O<2>, so that the admitted rates of H2 and O2 are in a ratio of 2:1. The initial filling of the reactor with one of the gases (for example H2) as a purging gas and the first feeding of the other gas (O2) at a rate exceeding the equivalence to the first gas have the consequence that, during the subsequent recombination, residue of the fed gas remains, which in turn is overcompensated by the next gas feed and is recombined with overstoichiometry of this gas. The constant repetition results in a continuous gas consumption which, in its course in time, oscillates between an overstoichiometry of O2 and an overstoichiometry of H2. <IMAGE>
