STEAM GENERATOR Russian patent published in 2007 - IPC F22B27/08 F28D7/02 

FIELD: power engineering, chemical industry.

SUBSTANCE: invention is designed for generation of steam. Proposed steam generator has cylindrical housing, coil and coaxial insert. Longitudinal ring channels between housing and coil and between insert and coil differ in section, first one exceeding section one, and are formed to provide maximum intensification of heat exchange, and insert is made sectional. Pitch of coil turns is made minimum possible to guarantee clearance between adjacent turns. Surfaces of housing and insert forming longitudinal ring channels can be made profiled. Housing of steam generator can be thermally insulated.

EFFECT: increased efficiency of heat exchange.
