FIELD: manufacturing technology.

SUBSTANCE: invention describes a method for producing a solid fuel, comprising the steps of preparing the suspension by mixing powdered low-grade coal and oil; evaporating moisture contained in the suspension by heating and separating the suspension obtained after the evaporation stage into a solid material and a liquid, wherein the evaporation stage includes the steps of heating suspension in the first circulation path and heating the heated suspension in the second circulation path, which is different from the first circulation path, and the process steam, formed at the evaporation stage, is used as a heat carrier for any one of the preheating stages and a heating stage, and the steam introduced from the outside is used as a heat carrier for another stage.

EFFECT: technical result of this method of producing solid fuels is that when producing solid fuels from low-grade coal, moisture can be evaporated efficiently, contained in the suspension, by increasing the efficiency of heat transfer.
