Kiln Flush: Scaffolding Board Fire
COUNTRY OF ORIGIN
ACCIDENT / INCIDENT DETAILS
A fire occurred in scaffolding boards erected on the kiln burner floor.
The scaffolding was erected so that part of it was above the cool air inlet to the duct taking hot kiln air to the raw mill.
Late in the day, the kiln was restarted after earlier being shut down. The kiln flushed and a surge of hot kiln gas and dust vented back through the inlet pipe. The fire was not observed when it occurred; the effects were discovered when the contractor attended the site during the following morning.
