给水量对机组热力性能影响的近似计算
摘要
电厂母管制高压给水流量分配由给水管路阻力特性决定
与机组负荷没有必然的对应关系。给水量变化对机组性能影响计算比较复杂
给水量对机组热力性能影响的近似计算是在加热器抽汽放热和给水吸热热平衡式基础上
补充加热器传热方程式
利用弗留格尔公式和实测隔离工况下机组性能曲线的一种计算方法
Abstract
Based on thermal balance between extraction steam and feed water in feed-heaters
using the flugel formula and measured performance curves under isolated conditions and added heat transfer equations
an approximate caculation method is given to determine the effect of feed water flow on thermal performance of generating unit.
