摘要

华能上海石洞口第二电厂超超临界660 MW机组给水泵汽轮机(小机)为ND(Z)84/79/07型变转速凝汽式汽轮机

采用弹簧基座

可满足主机在各种工况运行时对给水的要求。总结了小机的特点及运行中存在的问题

并对小机的优化运行提出了建议。

Abstract

The ultra-supercritical 660 MW unit in Huaneng Shanghai Shidongkou Power Plant no.2 has been equipped with a turbine-driven feed-water pump

the small turbine of which is a ND(Z)84/79/07 type condensing steam turbine with variable speed

and adopting a spring foundation

it can satisfy the requirements of feed-water pump under different operating conditions of the main unit.The features of small turbine for the feed-water pump

as well as problems existing in its operation have been summarized up

and recommendations for operation optimization of the said small turbine for feed-water pump being put forward.
