    • Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control of global warming. Flexible operation of CO2 capture and compression equipment will increase the competitiveness of power plants (1 ) designed for CO2 capture and compression and will allow earlier introduction of this kind of plants. The main objective of the present invention is to improve the plants frequency response characteristics by taking advantage of the additional flexibility, which can be realized by controlling the power consumption of the CO2 capture and compression system. One particular aim is to provide a power reserve for under- frequency events without deloading the plant (1 ) to part load. This is achieved by an operating method, in which the power consumption of the CO2 capture system is used to control the net output (D) of the plant (1 ). Besides the method a plant (1 ) designed to operate according to this method is subject of the present invention.

    • 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.
