Solar thermal power system has evaporation process for steam turbine plants running in day-night cycle in two working directions

摘要

The system has the evaporation process for its steam turbine plants running in a day-night cycle in two working direction. An easily evaporated fluid, e.g. H2O/NH3, is heated, evaporated and superheated by day in a solar radiation receiver (1). The steam drives a turbine (4). The relieved steam is then condensed in a condenser (5) and the condensation heat is stored in a heat store (8).
