Abstract

Experimental studies have been carried out to determine the energy and technical characteristics of composite fuels from coal grade 3B (Balakhtinskoye deposit), fine waste and flour from the milling industry. An effective concentration of 50% / 50% composite fuel has been established without the addition of a flour component, in which the combustion heat is reduced by less than 8%, with the flour component added up to 15%, the heat of combustion further decreases less than 2% of the heat of combustion of homogeneous coal. At the same time, the ash content is reduced to 11%, the yield of volatile components remains at the concentration level of the composite fuel of coal and wood. It is established that this component composition of three types of fuel is suitable for the formation of fuel briquettes suitable for burning in furnaces of small power boilers.
