Water vapor/exhaust steam condensation method for thermal power plant, involves supplying steam flow from condenser to deaerator in which feed water is heated by partial steam flow, parallel to heating of condensate in warming stage

摘要

The method involves supplying a turbine exhaust steam to an air-cooled condenser (3). Condensate extracted in the condenser is heated in a heating stage, before supplying to a tank, where the condensate is heated by the exhaust steam flow. Partial steam flow escaping from the condenser is supplied to a deaerator (8) in which cold additional feed water is heated by the partial steam flow, parallel to the heating of condensate.
