FIELD: thermal power engineering.
SUBSTANCE: invention relates to thermal power engineering and allows the use of medium metamorphism coals as a highly reactive solid fuel in systems for oil-free firing of boilers equipped with a muffle pre-furnace, or in other devices when highly reactive fuels based on medium metamorphism coals are required. The coal-based solid fuel mixture contains Kuznetsk coal grade D, to which highly reactive components are added, such as semi-coke obtained by gasification of brown coal, or pine sawdust, or Borodino brown coal grade 2B, in the following ratios, wt.%: Kuznetsk coal brand D 75-50, highly reactive components 25-50.
EFFECT: increasing the reactivity of Kuznetsk coal grade D.
