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.

Auxiliary steam generator system for a power plant

A steam generator comprising a combustion chamber having funnel-shaped side walls in the bottom area thereof and an encircling wall formed from a plurality of steam generator pipes through which a flow medium can flow, wherein there area as little temperature differences as possible in the flow medium at the output of the steam generator pies. The steam generator pipes are, more particularly, arranged in the lower section forming the funnel-shaped side walls such that they are exposed to heat in as homongenous a manner as possible. According to the invention, the diameter of a number of steam generator pipes in the region of the funnel shaped side walls is different from that in the region of the encircling wall.
