SURFACE HEAT EXCHANGER Russian patent published in 2006 - IPC F22D1/32 

FIELD: power engineering.

SUBSTANCE: surface heat exchanger comprises housing with the branch pipe for supplying steam and discharging condensate, water chamber with branch pipes for inflow and outflow of water to be heated, tubular system, and built-in cooler of the condensate provided with the horizontal baffles and vertical walls. The pipes whose bottom ends is in communication with the openings in the vertical side of the condensate cooler are mounted upstream of the branch pipe for discharging condensate. The openings are arranged under the level of condensate in the housing. The top end is connected with the openings in the bottom horizontal baffle of the prime condensate flow in the cooler.

EFFECT: enhanced efficiency and reduced cost.
