解决燃气锅炉缺水事故的方法
The ways to solve gas boiler water shortage accident
1 symbol:
1.1 a low water level alarm **s.
1.2 the water gauge instructions, local water level gauge to reduce or can't see the water level.
1.3 water flow abnormal is less than the steam flow (when the water wall tube or economizer tube damage instead)
1.4 severe water shortage, the main steam temperature is high.
1象征：
1.1发出低水位报警信号。
1.2各水位表指示降低，就地水位计降低或看不到水位。
1.3给水流量不正常的小于蒸汽流量（当水冷壁管或省煤器管损坏时相反）
1.4缺水严重时，主汽温升高。
Two reasons:
2.1 water supply automatic failure.
2.2 improper monitoring water level or wrong operation.
2.3 water supply valve failure.
2.4 water level gauge instructions on the high side, wrong operation.
2.5 the feed water pump failure, feed water pressure drop.
2.6 discharge door serious leakage, water wall, economizer tube blasting.
2原因：
2.1给水自动失灵。
2.2监视水位不当或误操作。
2.3给水阀门故障。
2.4水位计指示偏高，发生误操作。
2.5给水泵故障，给水压力下降。
2.6排污门严重泄漏，水冷壁、省煤器管爆破。
3 water treatment:
3.1 when a low water level alarm **s, check the water gauge and relevant meter, to make the right judgment.
3.2 such as water supply, automatic failure should manually and increase the water supply and contact thermal processing, such as drainage work
Shall be immediately stopped.
3.3 if the water pressure is low, should improve water supply pressure, at the same time decrease the steam pressure or lower water temperature.
3.4 if the above measures is invalid, should immediately report the long-term value, reduces the boiler load.
Such as the steam drum water level continues to fall to 3.5-300 - mm, delay of 1 second, MFT protection action, according to emergency boiler stop processing.
3.6 after cause water shortages have been eliminated by comprehensive examination think boiler no damage, slow water according to the value of long order to ignition.
3缺水的处理：
3.1当发出低水位报警信号时，应查看水位表和有关表计，做出正确判断。
3.2如给水自动失灵，应改手动并加大给水并联系热工处理，如有排污工
作应立即停止。
3.3若给水压力低，应提高给水压力，同时适当降低汽压或降低给水温度。
3.4如采取上述措施无效，应立即汇报值长，降低锅炉负荷。
3.5如汽包水位继续下降到-300mm，延时1秒，MFT保护动作，按紧急停炉处理。
3.6缺水原因查明消除后，经全面检查认为锅炉无损坏时，按值长令缓慢上水重新点火。
