FIELD: boiler engineering. SUBSTANCE: boiler for burning low-grade solid fuel at higher economical efficiency has furnace chamber with burner device which is connected with fuel heat treatment reactor by means of gas line. Fuel heat treatment reactor is connected with heat exchanger for cooling the coke-ash residue fed to air flow furnace by means of screw feeder. Air flow furnace is connected to cyclone for cleaning the combustion products of ash. One ash line of cyclone is connected with reactor and other ash line is connected to heat of last heat exchanger is connected to feed water pipe line and its outlet is connected to inlet of heat exchanger used for cooling the coke-ash residue whose outlet is connected with boiler economizer. EFFECT: high economical efficiency. 1 dwg
