FIELD: heat engineering.
SUBSTANCE: invention relates to heat engineering and can be used in fluidized bed boilers. Proposed is heat exchanger (10) with a fluidized bed of fluidized bed boiler (12), herewith the heat exchanger comprises front wall (16) adjacent to the fluidized bed boiler, rear wall (18) opposite to the front wall, and two side walls (60, 60′), herewith the walls are formed as water-pipe panels, inlet hole (24) located in the first section of the upper part of the heat exchanger for supply of hot particles from the fluidized bed boiler into the heat exchanger, heat transfer surfaces (34) for heat extraction from the particles and outlet hole (36) located in the second section of the upper part of the heat exchanger for return of cooled particles as an overflow from the heat exchanger back into the fluidized bed boiler, where the heat exchanger includes partition wall (26) between first (38) and second (40) sections of the upper part of the heat exchanger, herewith the partition wall runs from the front wall to the middle section of the heat exchanger, and the partition wall is formed by bending the boiling pipes at least from one side wall (60, 60′) of the heat exchanger.
EFFECT: technical result is reduction of the heat exchanger dimensions.
