Abstract
The technology and equipment were developed for the preparation and burning of suspension coal-water slurry fuel in boiler plants and heat power plants, obtained on the basis of fine dispersed waste coal (filter cakes) of processing plants. The studies were conducted on the basis of filter cakes from "Mine Komsomolets" and "Mine n.a. S.M. Kirov". It is shown that on the basis of these wastes it is possible to prepare suspension coal-water slurry fuel with a solid content up to 56-60%, the required structural and rheological characteristics and lower heat value up to 13 MJ/kg. On the basis of the research results, a working draft for the creation of a pilot technological complex, processing waste coal with the production of coal-water slurry fuel and its combustion in a boiler plant, was developed.
