基于机力塔风机相同运行条件下调整循环水流量对汽轮机组影响的分析

Study of the Influence of Adjusting Circulating Water Flow on Turbine Unit Based on the Same Operating Condition of Turbine

凝汽器真空是汽轮机运行中的重要参数,其数值的大小对汽轮机的运行安全经济性及调节性能都有很大的影响。影响凝汽器真空的原因是多方面的,在换热面积一定的情况下,主要有汽轮机排气量、循环水流量、循环水入口温度等。针对同等冷却风机运行条件下调整循环水流量对汽轮机组经济性的影响进行了分析。

Condenser vacuum is an important parameter in the operation of steam turbine.The value of condenser vacuum has great influence on the operation safety,economy and regulation performance of steam turbine.There are many reasons that affect the condenser vacuum.Under the condition of a certain heat exchange area,there are mainly steam turbine exhaust,circulating water flow,circulating water inlet temperature and so on.This paper analyzes the influence of adjusting circulating water flow rate on the economy of steam turbine unit under the same cooling fan operation condition.
