摘要

对石门电厂 2 0 0 3年 7月 4日的一次全炉膛灭火保护动作对全炉膛灭火保护逻辑进行分析

认为原逻辑中存在层运行信号相互屏蔽

而且油层无火判断条件不合适等现象

提出优化全炉膛灭火保护逻辑

将油层无火判断条件由 2 /4无火改为 3/4无火

Abstract

The outfire protection lo gi c

for overall furnace outfire protection in Shimen Thermal Power Plant that act ed on 7/4/2004

is analyzed in this paper. The electric power enterprise standard and the design principle used by CE company are employed in the analysis. It is pointed out that there exist mutual screen between different layers messages an d inappropriateness of the judging criterion for no fire on the oil layer. An op timal scheme is proposed for the overall furnace outfire protection logic

in wh ich the judging criterion for no fire on the oil layer is evaluated to 3/4 no fi re from 2/4 no fire.
