Verfahren und Einrichtung zur Gewinnung von Wasser bei einer Kraftwerksanlage

摘要

The gas turbine exhaust gas (15) water condensation system (1) has a vessel (10) with a pipe carrying the exhaust gas running through it. The exhaust gas may enter the vessel at a temperature of 98 degrees C. - A heat pump (21) with an evaporator (30) cools the exhaust pipe below its dew point of 43 degrees C, down to e.g. 40 degrees C. Condensed water (25) is separated from the exhaust gas and may be fed to a steam boiler. A condenser (35) at the output end of the vessel heats the exhaust gas back above the dew point to e.g. 90 degrees C.
