HEAT EXCHANGER Russian patent published in 2007 - IPC F22D1/32 

FIELD: power engineering, applicable in heat-exchange apparatuses of regenerative system, heat supply systems intended for water heating due to superheated steam heat.

SUBSTANCE: the heat exchanger has a case with a steam inlet connection, distributing chamber with heated water inlet and outlet pipe connections, tube system with partitions placed under the distributing water chamber, an additional water chamber with a tube plate and an additional tube system above it is installed in the bottom part of the case. Heated water inlet and outlet pipe connections are installed on the additional water chamber, the pipe connection of water outlet from the additional water chamber is connected by an external pipe-line to the heated water inlet connection on the distributing water chamber, a separating partition with holes and a water lock is installed between the tube systems in the heat exchanger case, and the condensate outlet pipe connection is installed on the case above the additional tube plate.

EFFECT: reduced "working" of the tube plates, which results in an enhanced reliability and economical efficiency of the heat exchanger.
