    摘要: To cover peak loads an auxiliary circuit having a water store which can be charged from the main circuit is connected to the main circuit of a thermal power station. The stored energy carrier is expanded by throttling, whereupon the vaporous part performs work in a peak-load turbine or in part of the main turbine, which is designed for this purpose, while the unvaporized part is returned to the main circuit in such a way that the low-pressure bleed points of the main turbine are relieved and the output of the main turbine is thus increased. The water store is preferably fed with condensate from the reheater.

    摘要: An arrangement for storing energy to cover peak-load conditions and serve as a stop-gap reserve in steam power plants. A live steam generator is connected to a steam turbine, and a storage vessel is provided with a steam cushion volume and a water content volume. The water content of the storage vessel is connected, on the one hand, to a single-or multi-stage secondary steam generator which is connected, in turn, on the steam side to the turbine by a working steam line. A hot-water return line connects the secondary steam generator on the water side to the feed water line and/or a compensation vessel connected to the feed water line. The steam cushion volume of the storage vessel is connected, on the other hand, by a steam line, to a point of the main steam cycle of the plant which is upstream of the entry point of the working steam line. In particular, the steam cushion is connected to the live steam line. The secondary steam generator may be in the form of one or several flash tanks or heat exchangers. It also may consist of several superheaters through which hot water flows.
