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 steam power plant is suggested having, parallel to the low-pressure passage (VW1 to VW2), a heat reservoir (A) which is loaded with preheated condensate in weak-load times. This preheated condensate is taken from the heat reservoir (A) for generating peak-load and inserted downstream of the low-pressure preheater passage (VW1 to VW2) into the condensate line that contacts the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.
摘要翻译： 建议蒸汽动力装置与低压通道（VW1至VW2）平行，具有在弱负载时加载预热冷凝物的蓄热器（A）。 该预热的冷凝物从蓄热器（A）取出，用于产生峰值负荷，并将其插入到低压预热器通道（VW1至VW2）的下游，进入与给水容器（8）接触的冷凝管。 因此，可以在不大幅度地改变蒸汽发生器（1）的锅炉的加热输出的情况下，在宽范围内快速地控制发电厂的发电。 因此，根据本发明配备的蒸汽发电厂可以以更大的负载变化进行操作并且还提供更多的控制能量。

This preheated condensate is taken from the heat reservoir (A) for generating peak-load and inserted downstream of the low-pressure preheater passage (VW1 to VW2) into the condensate line (19.2) resp. the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.

摘要： The feedwater preheating system includes a feedwater tank and a constant volume recirculation pump. The feedwater tank is adapted to store the feedwater. The feedwater tank includes feed and return lines. The feed line is adapted to feed the feedwater to the HRSG, and the return line enables returning of the feedwater into the feedwater tank. The return line precludes a control valve, and is configured to the feedwater tank to reduce component loss while feedwater recirculation. The constant volume recirculation pump is configured in the feed line to recirculate the feedwater between the HRSG and the feedwater tank. The pump is capable of recirculating the feedwater at constant speed and volume to reduce heat loss while feedwater recirculation, as against the prior art feedwater preheating systems.
