FIELD: heating liquids, gases and production of steam in power engineering. SUBSTANCE: heat carrier liquid flows from supercharger 1 to jet apparatus 5. Flue gases from furnace 21 are directed to jet apparatus 5 where the following processes occur: mixing, contact heat exchange, condensation of steam and deposition of solid particles. In separator 9, gas is separated and is evacuated into atmosphere through branch pipe 12. Heat transfer from gas and from heat-transfer agent to product to be heated is effected in heat exchangers 16 accompanied by sprinkling and overheating. Pressure is reduced in steam generator 39 after injector 40. Product being heated boils and gets cooled down due to evaporation and then it is directed to superheater 27. Steam is directed to steam superheater 30 through branch pipe 41. Superheated steam is delivered through branch pipe 32. EFFECT: enhanced efficiency. 6 cl, 1 dwg
