600MW燃煤机组锅炉熄火延迟跳机的分析处理

Analysis and treatment of the delayed tripping of the boiler in the coal-fired power plant

锅炉熄火延迟跳机即是当锅炉发生熄火事故时,据当时锅炉发生熄火的原因、性质决定是否解列机组运行;若此时对机组安全运行已存在威胁或机组已无法继续运行,则解列机组,确保机组安全,若还未对机组安全造成威胁或机组还可以继续运行,则利用锅炉蓄热带极低负荷继续运行,立即恢复锅炉系统运行,不解列机组。

Boiler flameout delay tripping is when the boiler flameout of the accident,according to the reason and the nature of flameout,decide whether to make column unit operation; if at this time to the safe operation of the unit has been in existence for threats or unit has been unable to continue running. Then make column unit,ensure the safety of unit,if it has no threat to the unit security or unit can also continue to run,then make it run using the boiler heat storage with very low load,and restore the boiler system operation,puzzled column unit.
