Abstract
In a once-through steam generator, a separating bottle (25) is inserted between the evaporator (22) and the superheater (23). To purify the water/steam circuit, a greater quantity of water than is necessary is conveyed through the evaporator (22) via a feed pump (20). The water quantity is measured in such a way that wet steam enters the separating bottle (25). This water fraction, together with all the impurities contained therein, is separated in said bottle and is drawn off via a blowdown line (29). On the occasion of overfeeding, a conditioning agent is metered to the water, in order to reduce the volatility of the substances to be separated.
