Method of converting a system generating saturated steam, having at least one steam turbine group, and power station converted in accordance with the method

摘要

A system (1) generating saturated steam is replaced by at least one gas turbine set (29, 30, 31, 36), at least one waste-heat boiler (32) and at least one back-pressure steam turbine (37). The back-pressure steam turbine (37) is coupled to the gas turbine set (29, 30, 31, 36), which back-pressure steam turbine is supplied by the steam generated in the waste-heat boiler (32). The exhaust steam of the back-pressure steam turbine (37) is supplied to the saturated-steam medium-pressure steam turbine (4).
