［摘要］給水泵是發(fā)電廠中最為重要的設(shè)備之一，其功能是將除氧器內(nèi)的飽和水輸送給鍋爐。給水泵配置及給水泵組運行的性能優(yōu)劣不僅影響其自身的安全性和經(jīng)濟性，而且決定了機組是否能長期安全穩(wěn)定運行。對于高位布置直冷機組，文章依托錦界三期布置特點提出給水泵最優(yōu)配置方案。

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.
