FIELD: heating equipment.
SUBSTANCE: invention relates to heat engineering and can be used in heat exchanger (1) operating on condensing boiler gas. Heat exchanger (1) equipped with appropriate tank (2), at least one tube bundle (3), at least one temperature sensor (4), at that, bundle (3) of tubes is formed by coil helically wound around central axis and forming corresponding number of turns limiting combustion chamber (300), and has first end (31), which serves as inlet for heated heat transfer medium, and second end (32), which serves as outlet for heat transfer medium, and partition (5) adapted to divide combustion chamber (300) into first detector chamber (310) and second condensing chamber (320), characterized in that baffle (5) is disk-shaped element with outer profile (51) of spiral shape, equipped with layer of insulating material (50); baffle plate (5) can be screwed along turns of tube bundle (3) to adjust and vary dimensions of chambers (310, 320).
EFFECT: disclosed is boiler heat exchanger.
