摘要： A system and method for warmkeeping a steam generator such as a sub-critical steam generator is disclosed. Water extraction piping extracts water from a component of one of the water fill circuits of the sub-critical steam generator. A deaerator heating system having an inventory tank of water mixes the extracted water with the water in the tank, and heats the mix of water to a predetermined temperature level to generate heated deaerated feedwater. Feedwater piping forwards the heated deaerated feedwater at the predetermined temperature level from the deaerator heating system to the water fill circuits of the sub-critical steam generator. The water extraction piping, the deaerator heating system and the feedwater piping operate cooperatively to warmkeep the water fill circuits in accordance with the predetermined temperature level while the sub-critical steam generator is in the unfired stand-by mode of operation.

摘要： A method for preheating untreated water in a power plant having a water/steam circuit, the power plant has a steam producer, a steam turbine, and steam lines, of which at least some connect the steam producer to the steam turbine, wherein untreated water for producing deionized water is heated by means of wastewater from the water/steam circuit and the wastewater is added to the untreated water in order to heat the untreated water. A power plant is adapted for preheating untreated water by the method.

摘要： A throttle device for varying the pressure of a fluid in a plurality of parallel outlets includes a fluid collector having at least an internal chamber, an inlet and a plurality of outlets for the fluid, and a control element displaceably mounted in the internal chamber of the fluid collector and comprises a plurality of orifices, the cross-section of which can be varied by a relative movement of the control element in relation to the fluid collector. The control element is a sleeve, wherein the orifices are disposed in the sleeve such that they correspond to the outlets of the fluid collector, wherein between the sleeve and the fluid collector seals are provided, such that in a region between of an outside surface of the sleeve and an inside surface surrounding the internal chamber of the fluid collector no fluid communication takes place between the orifices of the sleeve.
