METHOD FOR PREHEATING FEED WATER IN STEAM POWER PLANTS, WITH PROCESS STEAM OUTCOUPLING

摘要

A system for supplying feed water for an evaporator in a water-steam circuit has a condenser for condensing steam to obtain water that can be supplied with steam from a turbine installation. A degasification device for degasing condensate is coupled to the condenser such that a first portion of the condensate of the condenser can be fed to the degasification device. The heat exchanger is coupled to the condenser such that a second portion of the condensate of the condenser can be fed to the heat exchanger, the heat exchanger being coupled to a supply line such that feed water can be fed to the heat exchanger. The heat exchanger is configured such that the feed water can be heated using the second portion of the condensate. The heat exchanger is coupled to the degasification device such that the heated feed water can be fed to the degasification device.
