Abstract

The article presents the results of experimental studies of thermal processes in combustion and evaporation chambers of an experimental hydrogen-oxygen steam generator with a thermal capacity up to 25 MW developed at the Joint Institute for High Temperatures of the Russian Academy of Sciences (JIHT RAS). The studies have shown that the design of the mixing element has a significant effect on the heat fluxes in the combustion chamber. The effect of several designs on heat fluxes near the fire wall and on the completeness of the combustion of hydrogen in oxygen have been investigated experimentally. The result of experimental study of thermal processes in a hydrogen-oxygen-steam generator with a thermal capacity of up to 25 MW allowed estimating the real heat fluxes and correction factors for the calculations.
