1000MW机组给水系统管径优化选择

Optimum selection on pipe diameter of feed water system for 1000 MW units

介绍了浙江国华宁海电厂二期2×1 000MW扩建工程给水系统管径优化的情况,对高压给水管道管径优化进行了详细的计算和分析,在对给水系统管径的多方案进行技术经济比较后,给出了优选出的低压给水管道、高压给水管道以及给水再循环管道的规格。

This paper introduces the optimum selection on pipe diameter of feed water system for Zhejiang Guohua Ninghai Power Plant Phase Ⅱ 2 × 1 000 MW Extension Project. After advised calculation and analysis, comparing deferent schemes of pipe size of feed water system technically and economically, the optimized pipe specifications have been selected for low- pressure pipe, high- pressure pipe and recirculation pipe in the feed water system.
