Study On The Configuration Mode Of Feed Water Pump And Small Machine Of High-grade Direct Cooling Unit

Lu Feng

[Abstract]Feed water pump is the most important equipment in the power plant，and its function is to deliver the saturated water in the deaerator to the boiler.The configuration of feed pump and the performance of feed pump group not only affect its own safety and economy，but also determine whether the unit can operate safely and economically for a long time. For the high-level direct cooling unit，the optimal configuration scheme of the feed pump is proposed based on the layout characteristics of Jinjie Phase III.
