FIELD: production of coal-containing fuel; preparation of briquettes (granules) for furnace units of minor and medium heat power engineering. ^ SUBSTANCE: fuel (briquette, granule) contains 47.5-52.5% of culm, 28.5-31.5% of coal screenings and 19-21% of sawdust. Fuel thus produced is cheaper than similar fuels due to utilization of coal output wastes and wood-working process wastes without binding materials; fuel possesses high heat of combustion of coal; slag forming is excluded; finely-dispersed ash may be used as mineral fertilizer. ^ EFFECT: enhanced efficiency.
