Methods of burning solid fuel mixtures in power plants (review)

The paper presents one of the most accessible ways to transition to resource-saving and environmentally safe generation of heat and electricity by coal-fired thermal power facilities, which consists in burning fuel mixtures. A review of the existing experience in the transfer of existing heat engineering equipment both in Russia and abroad is carried out, the main difficulties in the process of burning solid fuel mixtures are described in detail. The most effective mixtures in terms of their environmental performance are obtained on the basis of coal and biomass with its addition in terms of heat content of no more than 20 %. The combustion remains one of the most complex and unexplored processes, and during the joint combustion of several solid fuels, additional interactions occur that affect the main combustion characteristics, therefore, the paper separately considers the methods for studying the combustion process and equipment for experimental combustion of solid fuel mixtures.
