FIELD: heat engineering.
SUBSTANCE: heating device comprises shell housing, combined coaxial surfaces, such as cylindrical surface and shell, two rows of axially aligned pipelines which provide gases to flow through the perforated face to the perforated plug, and ring space for flowing gas. Ring heat-resistant seals are interposed between the inner surface and outer side of the coaxially combined surfaces. The outer surface of the coaxially combined shell is provided with ring fins and axial stiffening members. The outer side of the shell housing is connected with the ring members secured to the coordinating supports. The surface of the shell housing is provided with welded members which are used in assembling the heating device. Fastening members are used for securing the face and flange to shell housing. The cylindrical surface is bounded with the perforated face and flat face which are fixed at the axis by axial stiffening members.
EFFECT: enhanced efficiency and expanded functional capabilities.
