Mathematical modeling of heat transfer processes of coal waste combustion in a chamber of automated energy generating complex

Abstract

The automated energy generating complex allows to obtain heat energy from water coal-water slurry fuel (WCF) that is a mixture of fine coal particles from coal enrichment wastes with water. The mixture under the pressure is blown into the swirl chamber through special sprayers. The received heat energy is used in different ways. One of the important issues is to estimate the heat losses through the walls of this chamber. In this research paper we solved the boundary problem of mathematical physics to estimate the temperature of fields in the walls of the swirl chamber. The obtained solution allows us to estimate the heat losses through the walls of the swirl chamber. The task of mathematical physics is solved by a numerical finite-difference method. The methods of solving this problem can be used in the calculation of temperature fields and evaluation of heat losses in other thermal power units.
