EXPERIMENTAL INVESTIGATION OF ELECTRICAL CONDUCTIVITY OF PRODUCTS OF COMBUSTION, STIMULATED BY SOLID PARTICLES,

Abstract

An experimental study was carried out on the electrical conducitivity of the products of combustion of methane with oxygen-enriched air in the presence of solid particles of various substances. This question merits attention in connection with the use of MHD electric power generators. By artificially introducing solid particles it was found possible to improve the electrophysical properties of the working gas. Solid particles transported from the combustion chamber may be present in the duct of an open-cycle MHD generator working with the products of coal combustion. In addition, when there are sufficiently large temperature reductions in the rear part of the duct, particles may form through the condensation of combustion product volatiles directly into the solid phase. The experiments showed that the introduction of particles stimulates the electrical conductivity of the products of methane combustion which, without particles, are non-conducting. The dependence of electrical conductivity on gas temperature and on particle size and the relative mass flow rate of the particles was studied. (Author)
