"Today's valve replacement is like
pulling a tooth from a tiger’s mouth.
The'tiger' is our gasifier, and the'tooth' is the Lv14005B faulty valve
After the failure of the Lv14005B valve, after a joint consultation with three units of gasification, electrical instrumentation, and maintenance, it was decided to replace the valve and pull out the "bad tooth"
.
During this period, in order to maintain continuous production of the gasifier, the black water in front of the valve has been temporarily cut to the V1048 settling tank
In the wind and rain, they were busy and orderly in accordance with the plan and many careful "desktop" deduction steps, carefully removing the peripheral "components
.
" The operator of the gasification branch processed the valves of the relevant pipelines in place, and the Lv14005B valve was cut out; the electrical personnel then removed the gas source device on the valve
At about 6 pm, all the related parts around the "teeth" were isolated, and the maintenance personnel followed closely.
The high-hanging inverted chain was like a large "surgical forceps", which could remove the "bad teeth" steadily, accurately and quickly.
Pull out the burner
.
At 9:30 in the evening, the new valve arrived in place
.
Following the pull back of the chain to the furnace mouth, a new "tooth" was smoothly inserted into the gasification furnace mouth, and the "tooth" replacement operation was a success
