摘要

以华电邹县发电厂1000 MW超超临界机组直流锅炉为例

介绍和分析了配有炉水循环泵内置式汽水分离器起动系统的锅炉水位控制策略。分离器储水罐水位控制与汽包水位控制有相似之处

但过程更为复杂。探讨了超超临界机组在热工控制上的技术特点。

Abstract

Taking ultra-supercritical once-through boiler of 1000 MW unit in Huadian Zhouxian Power Plant as an example

the strategy of water-level control in boiler with start-up system having internally positioned steam-water separater for allocated boiler-water circulating pump has been presented and analysed.The water-level control in water storage tank of the separator is similar to that in boiler drum

but the process is more complicated

thus

an approach to the technical features of thermal power control for ultra-supercritical units has been carried out.
