Abstract

The invention relates to a method for operating a steam power plant, particularly a combined cycle power plant (10), which comprises a gas turbine (11) an a steam/water cycle (20) with a heat recovery steam generator (16), through which the exhaust gases of the gas turbine (11) flow, a water-cooled condenser (21), a feedwater pump (26) and a steam turbine (17, 18, 19), whereby a cooling water pump (22) is provided for pumping cooling water through said water-cooled condenser (21), and evacuating means (25) are connected to said water-cooled condenser (21) for evacuating at least said water-cooled condenser (21) The inventive operating method is related to a shut down and start-up of said power plant (10) after said shut down and comprises the steps of: a) shutdown of the steam turbine (17, 18, 19) and gas turbine (11) and/or a combustor (13) of said gas turbine (11); b) restoration of a good vacuum within the condenser (21) by using said evacuating means (25); c) stopping said cooling water pump (22) of said water-cooled condenser (21) and said evacuating means (25), and filling up at least said condenser (21) with steam up to slightly above atmospheric pressure; d) controlling the pressure with a flow of said cooling water; e) after a certain shut-down period starting the cooling water pump (22) just before start-up of the plant (10); f) starting the plant (10).
