FIELD: gaseous heat carriers.
SUBSTANCE: body contains a pipe with a longitudinal cavity, a wall with an outer surface, an outer wall of a tubular shape with end sections, located relative to the pipe with the formation of a coaxial cavity, an inlet pipe for the coolant and an outlet pipe for the coolant, fixed to the outer wall of the tubular shape with end sections and communicated with coaxial cavity, vertical posts fixed to the outer surface of the wall of a horizontally oriented pipe. The body is equipped with two multilayer bellows. One of them is located between one of the end sections of the outer wall of the tubular shape and one of the vertical posts and is fixed to the latter, and the other is located between the other end section of the outer wall of the tubular shape and the other vertical post and is fixed to the latter. The inlet pipe for the coolant, the outlet pipe for the coolant, multilayer bellows, the outer wall are installed with the possibility of performing oscillatory radial and reciprocating movements relative to the wall. Vertical struts are fixed to the outer surface of the wall with the possibility of receiving vibrational radial and reciprocating movements from multilayer bellows and providing joint vibrational radial and reciprocating movements with the wall with the outer surface of the horizontally oriented pipe.
EFFECT: increased service life of the device by increasing the time of formation of deposits on the surfaces of steel parts, compensation for thermal expansions and elongations of the elements of the device for the case when the temperature of the gaseous heat carrier at the point of supply is 650°С.
