Burning of methane-oxygen mixture in the environment of overheated steam of atmospheric pressure

The relevance of the research is caused by necessity of making highly effective power-generating units on one of the directions, providing working out of a construction of the steam superheater and production engineering of steam overheat up to temperatures above 800 °С of the supercritical pressure before the immediate steam feeding into a turbine. The operation purpose: examination of the influence of enthalpic metering characteristics of a gas mixture (CH4+O2) close to stoichiometric composition, and feebly overheated steam of atmospheric pressure on the temperature of the reacting medium (products of combustion in the environment of steam), and also on qualitative and quantitative composition of a steam-gaseous intermixture over the range of metering characteristics of stable and resistant to burning. Research techniques. The authors used proved measurement techniques of all parameters of process in the automated mode of gathering and processing of the primary information: temperature, pressure, charge, composition of a gas condensed phase. The flowing method of concentration measuring of products in real time mode with a margin error ±5 % was also used.
