| 摘要 |
<p>The invention relates to a feedwater supply arrangement in a steam generator, preferably in a waste-heat boiler of a combined cycle power plant having at least one waste-heat boiler which is equipped with a high-pressure system and with a low-pressure system which in each case can be supplied from at least one feedwater vessel (container) (10) and whose feedwater pump lines (trains of pipes) (26 to 31) are respectively designed with three-fold redundancy. Said feedwater pump lines (26 to 31) have pumps (32, 33) with an electric drive motor (35). In each case, one pump (32) for the low-pressure system and one pump (33) for the high-pressure system have a common drive motor (35). <IMAGE></p> |
