WATER STEAM REHEATER Russian patent published in 2009 - IPC F22D1/32 

FIELD: heating.

SUBSTANCE: invention relates to the field of power engineering and is to find application in vertical heat exchanger water steam reheaters of feed heating and heat supply systems designed for delivery of water due to steam condensation and steam condensate depression on the heat exchange surface tubes. Proposed is a vertical water steam reheater that contains a water chamber with heated water inlet and outlet nipples, a housing with a heating steam inlet nipple and steam condensate outlet and a tubular system. The casing installation reserves some tubes of the above system to act as a condensate chiller when heated water is supplied into them. Condensate supplied from the container into the chiller becomes discharged therefrom through the hydraulic gate positioned next to the condensate chiller on the side opposite to that of the condensate outlet nipple installation on the housing. The lower part of the hydraulic gate vertical sheets is positioned next to the tube plate below the condensate level. Over the condensate outlet nipple between the housing and the chiller casing butt sheet there is a horizontal separating partition mounted.

EFFECT: maintenance of condensate depression provided for by the integrated chiller which improves cost-efficiency and reliability of the reheater operation.
