The unit has an emergency trip, what is the matter with it?
机组事故跳闸，出了什么问题？
It is because of the overfeed of the water into drum
是因为汽包满水
tube burst 爆管
coal jamming 堵煤
pulverized coal deposits 积粉
too low drum water level 汽包水位过低
high pressure in the furnace 炉膛压力高
tripping of the draft fans 风机跳闸
damage of water wall tube 水冷壁管损坏
would you please describe the water-gas circulation process to us?
请你说一下水汽循环过程好吗？
OK，I’ll start from here. The feedwater coming from machine room enters the economizer at the bottom of the rear pass and then goes through this exchanger to the drum.
好吧，从这儿开始。从汽机房来的给水线进入后烟道底部的省煤器，再经过这个交换器进入汽包。
The downcomers convey the water from the drum to the lower ring distribution header.
下降管将从汽包来的水流送入下部环形集箱。
