Abstract (en)
[origin: WO2013005071A1] 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.
