Verfahren zum Kondensieren des Abdampfes einer Turbine im Dampfkraftwerk

摘要

A method of condensing the turbine exhaust at a power plant, characterized in that the turbine exhaust is introduced into a direct-contact type condenser which works under a vacuum condition and is condensed by its direct contact with cooling water. Mixed water of the cooling water and condensed water is drawn out of said condenser, a part of the mixed water is cooled by an air-cooled heat exchanger and is further cooled by a heat exchange with liquefied gas down below a temperature corresponding to the degree of vacuum of said condenser for circulation and use as cooling water for said condenser. The remainder is returned to the feed water system of the boiler and the gas vaporized by the afore-mentioned heat exchange is used as boiler fuel.
