TECHNOLOGICAL HEATER Russian patent published in 2005 - IPC

FIELD: the invention is intended for heating liquids, gases and their mixtures and may be used in various sectors of industry.

SUBSTANCE: the heater has a burner, a vertically installed house-tube heat exchanger shielded at least with two belts of bayonet chimneys with ring-shaped gaps and interior tubes which are connected via replacement sockets with collectors of output and input of environment. They are installed in the lower part of the heater. A generator is installed in the ring-shaped gap. Directly beyond the ring supporting bayonet chimneys and limiting the combustion zone with a partition a cowl is installed. It is fulfilled in the shape of a hollow cylinder coaxial with the casing of the heat exchanger and the chimney and placed in the paraxial part of the heater unengaged with tubes. The nose of cone of the cowl is inverted to the side of the burner so that ring-shaped area between the cowl and the casing full of tubes develops a cavity of convective section. At that before entering into the chimney the indicated section ends with openings which are located on equal distances to diameter of the cowl and oriented against spaces between bayonet chimneys of interior belt of matrix of the heat exchanger.

EFFECT: provides increasing performance reliability and effectiveness of the heater.
