恒运电厂5号机抽汽供热改造

Modification of unit 5 steam turbine to extracting and supplying heat unit in Hengyun Power Plant

介绍将高压单缸凝汽式汽轮机改造为抽汽供热式机组的设计思路及施工改造过程。对改造中出现的新问题进行了分析并提出解决办法。改造后 ,机组抽气直接供给热网 。

The device thoughts and modification progress that modified one cylinder with high pressure,condensing steam turbine to a extraction and supplying heater ones are introduced. New problems during this modification are analyzed and the ways to solve them are presented. As a matter of fact , the steam turbine is successfully modified to be an extracting and heat unit which can supply heat directly to network with a high social and economic efficiency.
