摘要

给出一种新颖的凝汽器后水室连通管优化设计方案

将汽机房平台柱子通过低流阻翼形套管

直接穿过凝汽器后水室连通管

使得双背压凝汽器后水室之间连通管实现了直通连接

解决了双背压凝汽器后水室连通管常规设计占地大、管线长、弯头多

阻力大的弊端

不仅有利于主厂房的布置

还可节省60 t钢材用量

年降低厂用电610MWh。同时还给出了优化设计的计算模型和计算公式。

Abstract

This paper describes a new optimized design scheme for the connecting pipes of condenser rear water chambers. In this proposal

the columns of turbine house passes through the connecting pipes of condenser rear water chambers via low resistance alary casings so that the double pressure condenser rear water chambers can be directly connected by the pipes with short pipeline

less elbows and low resistance. It is not only good for the turbine house arrangement

but also can save 60 tones of steel comsumption and reduce the auxiliary power 61× 104 kWh. Moreover

this paper provides the calculating model and relevant formulas.
