The major hazards involved in this type of power plant are fire and explosion hazards. If the boiler is not maintained properly or any deviation of operation from the original process occurred, then there might be risk of explosion [8, 9].One of the best examples of boiler explosion is which happened at NTPC Unchahar coalfired power plant on November 1, 2017, which was a newly commissioned ...

Like the EVN, the IV8 flameless explosion vent provides an explosion protection solution for process vessels inside a building or areas where standard explosion venting is unsafe. When an explosion occurs, the explosion vent opens, allowing the explosion pressure and flame through a flame arrestor which cools the gases and quenches the flame.

Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shockresistant. NFPA requires coal mills to be good for 50 PSI.
