FIELD: power engineering.
SUBSTANCE: tube shell, in which there is an inner collector to remove condensate and made in the form of a tube with a slot. Two steel strips welded along both long and one of short sides and forming a spiral channel. Short ends of strips that are not welded to each other are welded to the collector's tube wall. A steel corrugate sheet installed in the spiral channel to form channels for air blowing, corrugations of which are parallel to the axis of the spiral formed by steel strips. A nozzle for input of the oxygen-hydrogen mixture and its discharge from the spiral channel attached to the spiral formed by steel strips and a flange with pins.
EFFECT: invention makes it possible to increase the permissible pressure in the air cooler channel.
