FIRE AND EXPLOSION PREVENTION IN COAL PULVERIZING SYSTEMS by THOMAS F. ROBINSON, Manager-Product Development Group Fuel Burning Engineering RILEY STOKER CORPORATION WORCESTER, MASSACHUSETTS INTRODUCTION The safety record and availability history of coal pulverizing systems in the electric utility industry is com- mendable.
Dust Explosion Prevention A dust cloud of flammable concentration can be produced in industry either by design or by chance. For example, lean-phase pneumatic transfer systems handling flammable dust have an almost continual dust cloud present. In processes such as the filling and emptying of dust containers a dust cloud of flammable concentration is produced transiently.

Explosion Protection for Coal Mills in Power Plants. In the filter the coal dust is dispersed and can be ignited as well. Therefore the filter has to be protected by vacuum resistant bursting discs such as the ODV and EDP, which protect the filter against excessive pressure in case of an explosion. The quantity of vents depends on the filter size (volume) and pressure resistance.
