摘要

浙江国华宁海发电厂(宁海电厂)二期超超临界2×1000 MW机组参照国外已有的大容量超超临界机组给水泵配置经验

结合起动运行要求

提出并采用了取消电动给水泵(电泵)的配置方案。通过对超超临界1000 MW机组无电泵起动模式的分析

认为新建机组采用无电泵配置是可行的

但须是具有3台以上机组的电厂。

Abstract

In the light of existing installation experiences of large-capacity ultra-supercritical units from abroad

and combining with the requirements in start-up and operation of ultra-supercritical 1 000 MW units

a tentative idea of eliminating motor-driven feed-water pumps for ultra-supercritical 2×1000 MW units in second-phase project of Zhejiang Guodian Ninghai Power Plant has been put forward.Through analysis of start-up mode without motor-driven feed-water pump for ultra-supercritical 1 000 MW unit

it is believed that the installation mode without motor-driven feed water pump is feasible for newly constructed units

however

it is necessary to have more than three units in one power plant.
