Economic Analysis of Feed water Pump Configuration Scheme of High-grade Direct Cooling Unit Cui Guang-lan

［Abstract］After comprehensive comparison，it is considered that the current large unit using steam feed pump scheme is better than the electric feed pump scheme.For the high layout direct cooling unit，based on the characteristics of Jinjie phase III layout，the steam feed pump + direct discharge scheme has the lowest investment and the best economic benefit.

［Keywords］high layout of direct air cooling；feed water pump configuration；economic and technical comparison

給水泵組作為發(fā)電機組的重要輔機，其配置方式的優(yōu)劣不但影響到熱力系統(tǒng)的安全性和經(jīng)濟性，而且對電廠的投資以及投資商的增減也有較大影響［1］。（剩余1820字）
