摘要:

凝汽器结垢是电厂循环水处理中较为常见的问题。凝汽器严重结垢会影响冷凝效果,端差上升,真空度下降,从而影响机组出力,供电煤耗上升等。通过对某公司凝汽器运行状况监测和凝汽器内部情况检查,分析凝汽器结垢的原因,制定了凝汽器的物理清洗和循环水加药方式优化等综合治理方案,在清除凝汽器结垢的同时,有效减缓凝汽器结垢,提高凝汽器真空,为凝汽器长期有效地高效率运行提供保障,从而提高发电机组运行效率。

Abstract:

Condenser scaling is a common problem of circulating water treatment in power plants.The scaling of condenser will seriously affect the condensation effect,increase the terminal temperature difference and decrease the vacuum degrees,which affects the output of units,and coal consumption for power supply.Analyzing condenser scaling by monitoring the operation status and inspecting the internal condition of condensers in a company,causes for scaling are given.In view of the reasons,comprehensive treatment such as physical cleaning and dosing recirculating water are formulated.Removing the scaling of condenser and effectively mitigating the process of scaling can improve the vacuum of condenser,which provides guarantee for the longterm effective and efficient operation of condenser and generator set.
