Abstract: In a steam power plant, a first cooling circuit includes a condenser for condensing steam and a first pump for pumping a first cooling fluid through the condenser in order to cool the condenser. A third cooling circuit is a closed cycle cooling circuit that utilizes a second cooling fluid for cooling down at least one component that is different from the condenser. A second cooling circuit includes a heat exchanger that thermally couples the first cooling fluid and the second cooling fluid and utilizes the first cooling fluid in the heat exchanger for cooling down the second fluid and further includes a second pump for pumping the first cooling fluid through the second cooling circuit independently from an operation of the first pump.

Abstract: A system and method for reducing a velocity deficit from an aerodynamic body is disclosed. An air jet is injected into an ejector mixing chamber in the aerodynamic body. The air jet creates a suction effect in the ejector mixing chamber, which suctions boundary layer air from a perforated surface in at least one side of the aerodynamic body into a plenum chamber and into the ejector mixing chamber. The air jet ejects the boundary layer air and the air jet from a trailing edge slot of the ejector mixing chamber. Suctioning the boundary layer air and ejecting the boundary layer air and the air jet from the trailing edge slot reduces a velocity deficit on a trailing edge of the aerodynamic body. The reduced velocity deficit and the suctioning of boundary layer air reduce noise, turbulence, blade stress, and blade deformation.

Abstract: A run-up method for a solar steam power plant is proposed. In the run-up method an auxiliary steam is used to generate seal steam for a steam-turbine of the power plant. The auxiliary steam is produced by a heat-exchanger-system that is to provide, during a subsequent power-mode, overheated steam for driving the steam-turbine.
