Abstract
An auxiliary steam generator system for a power plant, comprising a water-steam circuit, which has a condensate line and a feed-water line, wherein a condensate pump is connected in the condensate line and a feed-water pump is connected in the feed-water line, and wherein a pressure accumulating vessel is connected between the condensate pump and the feed-water pump, and wherein a feed-water take-off line is connected to the water-steam circuit at a branch-off point after the pressure accumulating vessel is provided. The feed-water take-off line is connected to the pressure accumulating vessel and a heating device is connected in the feed-water take-off line.
Claims16
An auxiliary steam generator system for a power plant, with a water-steam cycle, comprising a condensate line with one end connected to a pressure accumulating vessel, a compensating line and a feed-water line, wherein a condensate pump is connected into the condensate line and a feed-water pump is connected into the feed-water line, and wherein the pressure accumulating vessel is connected between the condensate pump and the feed-water pump, and wherein a feed-water extraction line is connected at a branch point to the water-steam cycle downstream of the pressure accumulating vessel, wherein the compensating line connects the condensate line into the feed-water extraction line and the feed-water extraction line is connected to the pressure accumulating vessel, and in that a heating device is connected into the feed-water extraction line.
A method for auxiliary steam generation in a power plant process with an accumulator which is connected into a water-steam cycle and into which condensate from the water-steam cycle is delivered, and the condensate is stored, mixed and degassed in the accumulator, and the condensate is then discharged from the accumulator as feed water;
- and a partial flow of the discharged feed water is extracted, wherein the partial flow is electrically heated during a heating process, and the heated partial flow is fed back into the accumulator.
