Unfortunately this has happened before at a plant in Europe. It is usually asociated with heating the kiln on gas and demonstrates that it is critical to have the flame detection working and operators properly trained to not purely rely on the instrumentation.
If you can provide pictures to info@cemnet.com I think this episode is worthy of a full description in ICR, which I would be happy to co-write if you can agree to that.
Hey Friends,
I am really sorry for this accident but don't you agree with me most of big accidents happen at night (or night shift)!!!

Very good information for us, thank you.
I have been in gas firing since last 15 years in cement. sorry to say but,
-first it's a system failure, not operators mistake
- the total practise followed is absolutely wrong, unsafe.
-standard operating procedure was not there.
- the process interlocks are not correct.
- I am not surprised with this accident, it was obvious with the practise followed. but happy to know that there was no fatality.
You should not allow gas flow without ph fan running.
Please avoid manual torch, I know pilot does not work all the time, ask FCT they have exceleent technology for cement burner pilots.
very high low or high pressure at smoke box should trip gas flow
the rate of temp decrease should trip gas flow.
there should be 2 flame sensors
the gas should be started from burner plateform after lookind flame inside (pilot), not from CCR.
etc.
Hi Nail,
Could you send me the detail accident report I wanna share with the plants since I could have been asked the source.
