摘要

以国华定洲发电厂二期超临界2×660MW直接空冷机组为例

分析2台机组在化学清洗、冷/热态冲洗、精处理投运、空冷凝汽器热态冲洗及整套启动过程中汽水品质的控制要点。由于采取有效的控制措施

2台机组的汽水品质在整套启动带负荷阶段即达到运行机组的要求

从而较大程度地提高了设备运行的安全性。

Abstract

Taking two supercritical 660 MW direct air cooing units in Hebei Guohua Dingzhou Power Plant as the example

the steam-water control points during the chemical cleaning

cold/hot state washing

polishing operation

hot state washing of air cooling condenser and the entire startup process were discussed.Because of the effective control measures

the steam-water quality of the above two units met the requirements during the startup with load process

which indicated the operation safety of the equipments was significantly enhance.
