Logic Problem Analysis of Overall Furnace Outfire Protection in Shimen Thermal Power Plant
Zhuo Gang · Hunan Electric Power · 2004
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.
