PROCESS AND DEVICE FOR OPERATING THE WATER-STEAM CIRCUIT OF A THERMOELECTRIC POWER STATION

摘要

A process is disclosed for operating the water-steam circuit of a thermoelectric power station, for example a steam power station, a heating or combined heating and power station, with a condensate pre-heating section (20), a steam generator (30) and a steam turbine (10) with condenser (12) and subsequent condensate preparation unit (14) arranged dowstream, with at least one condensate pump (16) upstream thereof. Steam tapped from the steam turbine (10) and/or from a steam overheating (32) is applied on the prepared condensate in the pre-heating section (20), thus heating it before it is supplied to the steam generator (30). The condensate is preprocessed before it reaches the pre-heating section (20) and need then not be degassed while it flows through the pre-heating section (20).
