    • A fossil fuel fired power plant (PP) can provide an improved dynamic response by means of condensate stop and optionally with indirect firing. The power plant (PP) having a water steam cycle comprises six condensate preheaters (21 -26) arranged in series for the preheating by heat exchange with steam extracted from the steam turbines (7-10). Steam extraction lines (23'-26') have a quick-action valve (23"-26") able to stop the extraction steam flow, whereby the additional steam flowing through the turbines enables a large load increase up to 10% within a short time of 10 seconds. In case of a coal-fired power plant (PP), the power plant (PP) comprises a supply silo (45) for pulverized coal that enables a quick increase in supply rate of coal to the boiler (1 ) and of the firing rate. This allows the load increase to be maintained over a longer time period.

    • A feedwater heater (14) in a heat recovery steam generator (A,B) lies within a flow of hot exhaust gas. The feedwater heater (14) converts subcooled feedwater into saturated feedwater water, the temperature of which is only lightly above the acid dew point temperature of the exhaust gas so that corrosive acids do not condense on coils (18) of the feedwater heater (14). Yet the temperature of the saturated feedwater lies significantly below the temperature of the exhaust gas at the coils (18), so that the coils (18) operate efficiently and require minimal surface area. Pumps (26, 28, 30) elevate the pressure of the saturated feedwater and direct it into an economizer (64, 90) where, owing to the increase in pressure, the water is again subcooled. The economizer (64, 90) elevates the temperature still further and delivers the higher pressure feedwater to evaporators (34, 70, 78) that convert it into saturated steam that flows on to the superheaters (50, 78, 84). Higher pressure pegging stem admitted to the feedwater heater (14) controls the pressure - and temperature - of saturated steam and water in the feedwater heater (14).
    • 热回收蒸汽发生器(A,B)中的给水加热器(14)位于热废气流中。 给水加热器(14)将过冷的给水转化成饱和给水水,其温度仅轻微地高于废气的酸露点温度,使得腐蚀性酸不会在给水加热器(14)的线圈(18)上冷凝, 。 然而,饱和给水的温度明显低于线圈(18)处的废气温度,使得线圈(18)有效地工作并且需要最小的表面积。 泵(26,28,30)提升饱和给水的压力并将其引导到节能器(64,90)中,其中由于压力的增加,水再次被过冷。 节能器(64,90)进一步升高温度并将较高压力的给水输送到蒸发器(34,70,78),蒸发器将其转化成饱和的蒸汽,其流过过热器(50,78,84)。 给水加热器(14)中允许的较高压力的夹紧杆控制给水加热器(14)中饱和蒸汽和水的压力和温度。
