Abstract
A method for flexibly operating a nuclear power plant with a waste heat steam generator that operates according to the forced-flow principle and that has heating surfaces of different stages of the waste heat steam generator, the heating surfaces being arranged in the flue gas channel, is provided. In order to increase the output, a mass flow of the feedwater flowing through the heating surfaces is increased while almost simultaneously activating a supplementary firing arranged in the flue gas channel of the waste heat steam generator.
Claims3
A method for the flexible operation of a power plant with a waste heat steam generator that works according to a once-through principle and has a plurality of heating surfaces of various stages of the waste heat steam generator arranged in a flue gas duct, wherein to increase power at approximately the same time as an additional firing, arranged in the flue gas duct of the waste heat steam generator, is brought on-line, a mass flow rate of the feed water flowing through the plurality of heating surfaces is increased.
