STEAM TURBINE CONDENSER Russian patent published in 2001 - IPC

FIELD: steam turbines. SUBSTANCE: proposed condenser has shell, water chambers and tube bank located between them. Water chambers are provided with one or more partitions forming separate passages for tube bank, organizing several passes of cooling water flow or passing two separate flows through two parts of condenser. Partition is provided with controllable damper; when this damper is open, by-pass of two-pass of cooling water may be made, thus reducing rate of water flow through tube bank or ensuring operation of two separate parts of condenser at delivery of water be one circulating pump. Beside that, condenser may be additionally provided with one more damper made in form of check valve; when circulating pump working for given water chamber is switched off, inlet hole of this chamber will be automatically closed. EFFECT: simplification of cooling water piping system; enhanced efficiency of control of such system. 4 cl, 1 dwg
