| Abstract: | The design and operation of feed-water system of 350 MW import unit are introduced.Some problems on steam distribution mechanism of feed pump turbine and feed-water regulation are analyzed in detail.Through transforming the feed-water system,the operation security and flexibility are improved.Boiler feed mode is proposed to optimize during startup and shutdown period,turbine-driven feed pump instead of motor-driven feed pump is used to control boiler feed-water,the economy of units is improved. |
