摘要

介绍了华能浙江分公司玉环电厂(华能玉环电厂)超超临界1000 MW汽轮机过载补汽技术。采用过载补汽技术

在额定工况以下补汽阀未开启时机组经济性有很大提高

并具备调频能力。在额定工况以上

补汽阀开启时

因节流机组经济性下降。

Abstract

The technology of additionally supplying steam at overload to ultra-supercritical 1000 MW steam turbine in Yuhuan Power Plant has been correspondingly presented.Adopting said technology

the economic behavior of said unit has been greatly enhanced in case without opening the supplementary steam valve below rated operating condition

and having capability of regulating frequency;but the economic behavior of said unit is decreased due to throttle at the time of opening the supplementary steam valve after rated operating condition.
