DOUBLE-PRESSURE TYPE CONDENSER, AND CONDENSATE REHEATING METHOD

摘要

Provided is a multi-pressure condenser for heating the condensate of a low-pressure condenser (10) with the steam in high-pressure condensers (20, 30), thereby to improve a plant efficiency. A heat transfer tube (61) is introduced into the condensate produced in the low-pressure condenser (10), thereby to feed the inside of the heat transfer tube (61) with the vent gas of a deaerator (2), so that the condensate and the vent gas of the deaerator (2) may perform a heat exchange to heat the condensate.
