FIELD: fire heat-power engineering; power engineering. SUBSTANCE: method of burning solid fuel includes thermal preparation of fuel through burning high-reaction fuel; after burning high-reaction fuel, two-phase fuel-and-gas suspension is obtained which is directed to boiler furnace for complete combustion with part of secondary air. Other part of secondary air is directed to zone of mixing the gas suspension thus obtained with combustion products of high-reaction (initiating) fuel at angle relative to axis of translational motion of gas suspension forming area of intensive mixing of gas suspension, combustion products of high-reaction fuel and secondary air. EFFECT: improved quality of burning fuel. 1 dwg
