Coal Mill Safety

Coal mill systems and their safety have taken a back seat for decades. Of course, where there is not a focus on explosion protection, the supplier can create systems that are really dangerous. There are numerous suppliers all over the world, but particuarly in Asia, that do not understand the safety principles and, some might say, don’t particularly want to.

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 shock-resistant. NFPA requires coal mills to be good for 50 PSI.

2018. 6. 7.  It is important to remember that a mill fire, whether it be flaming, smoking or smoldering coal inside the mill means a mill explosion could be occur at any time. Any burning or smoldering material inside the mill can evolve into an explosion because they provide an ignition source if the air to fuel (coal) ratio is elevated or higher than desired.

Coal dust Wikipedia

2021. 7. 29.  Coal dust suspended in air is explosive—coal dust has far more surface area per unit weight than lumps of coal, and is more susceptible to spontaneous combustion.As a result, a nearly empty coal store is a greater explosion risk than a full one. The main attempts at prevention include using safety lamps, adding stone dust coffers to mine galleries to dilute the coal dust, watering workings
