HEAT EXCHANGER Russian patent published in 2010 - IPC F28D7/00 

FIELD: heating systems.

SUBSTANCE: heat exchanger includes housing with bank of heat exchange tubes fixed in tube sheets, feed water supply tube, feed water header, superheated steam header, electric cable for magnetohydrodynamic pump; it is equipped with shell located inside bank of heat exchange tubes; at that, tube sheet of superheated steam header is fixed in series of shell, feed water supply tube is located coaxially and with a gap relative to shell with possibility of thermal expansion towards feed water header.

EFFECT: heat exchanger design of the proposed type allows increasing heat exchange intensity, uniformity of temperature field in cross section of tube bank, operating reliability owing to possibility of moving tube bank at thermal linear expansions.
