The accidents with Shell furnaces that I have experienced
Thread Content
I joined the construction site in 2007 to carry out various installation tasks and learn relevant skills, and I was involved in multiple start-up and shutdown processes. I am now sharing the various accidents I have experienced with everyone. 1. During the heating of the hot air furnace, an explosion occurred, causing the chimney cover to fly off. 2. Full closure of the recirculation air vent valve caused the S1103 explosion-proof plate to crack. 3. Smoldering in the V1205 high-pressure coal storage tank during shutdown (the handling procedure prevented the incident from escalating). 4. During operation, one set of the fly ash filter backflush valves stopped functioning; they were restored to service after the fault was resolved without shutting down the plant. 5. Slag skimmer chain broke N times. 6. To be continued. . . . . . . . Rest first before going to work tomorrow
A few words on that as well: burner nozzle leakage, damaged burners, high pressure difference in the gasification furnace (leaks in the pipes inside the furnace), oxygen tube explosions, etc
Explosion of the coal powder pipeline \ Explosion of the pressure-proof plate in the coal powder bin. What is the current status of the slag removal machine in question? Is the chain broken, and what measures have been taken?
If a problem occurs, is it due to issues during the construction process or problems in usage?
I’m not sure what you mean by an oxygen tube exploding; I look forward to a detailed explanation! !
1. The burner was damaged during startup. 2. Coal mill powder leakage ； 3. S-1307: Shutdown due to high pressure difference ； 4. P-1301 stops while the other one does not stop automatically ； 5. The slag skimmer is damaged; slag discharge will now be done on-site ； 6. Severe dust accumulation; shutdown due to temperature exceeding 18°C ； 7. Shutdown due to low water flow for adjustment, etc
1. Coal dust leakage has resulted in poor hygiene in the plant area； 2. The coal grinder during testing causes vibrations that are extremely severe ； 3. The slag skimmer experienced n chain breaks, with n emergency repairs carried out ； 4. The vibration level of the quench gas compressor was high, forcing it to shut down ； 5. The spiral feeder got stuck due to reverse rotation; emergency repairs were carried out overnight ； 6. The limestone feeder keeps getting “stuck” over and over again, and has to be “restarted” repeatedly” ； . . . . . . . Endless stories of black and white!
