Title:
CONDENSER WITH SEPARATE HOTWELL
Document Type and Number:
Japanese Patent JPH01193698
Kind Code:
A
Abstract:
PURPOSE:To enable minimization of T/G support, simplification of an indoor layout, and piping and equipment related to a condenser, by placing a hotwell separately as a condensate tank and by connecting a condenser and the hotwell with a piping and a pump. CONSTITUTION:A condenser 1 is placed under a turbine 2 and a condensate ditch 9 is provided at the lowermost part of the condenser. The condensate tank 3 has a constitution being connected to the condensate ditch 9 by a piping 10 and a pump 11. A steam discharged from the turbine 2 heats up a feed water through a feed water heater 6, moves to a cooling pipe 7 and arrives at the bottom of the condenser 1 after being cooled down and condensed to water. The bottom surface of the condenser 1 is inclined for the condensate to flow into the ditch 9. The condensate stored in the ditch 9 is sucked to the condensate tank 3 by the pump 11 connected with the piping 10. A hotwell which store the condensate temporarily, is used as the condensate tank 3 separated from the condenser 1, and is connected to the condenser 1 by the pump 11. As the result, the condenser 1 can have a structure as lower as a height of the hotwell therefore a smaller sized T/G support can be applied.
