摘要

结合某超临界600MW机组带炉水循环泵内置式起动系统的锅炉给水控制系统实例

在对全负荷范围给水调节过程分析的基础上

介绍了采用蒸发器吸热量及其焓增控制燃水比、分离器出口焓值校正燃水比、一级减温器温降校正给水流量的典型四回路给水控制系统及其工作原理。

Abstract

Combining with concrete example of a boiler feed-water control system in the start-up system with built - in boiler water circulatory pump for one 600 MW supercritical unit

and based on analysis of feed-water regulating process in the full load range

a typical four-loop feed-water control system and its working principle have been presented

the said system controls fuel/water ratio by using heat absorption and enthalpy increase of the evaporator

and corrects fuel/water ratio by using the enthalpy value at outlet of the separater

as well as correcting feed-water flow rate by using the temperature decrease of the first-stage desuperheater.
