point of combustion. In the air-conveyed direct-fired coal pulverizing system, used extensively in the industry today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment. Hence there is the continual danger of fires and, under certain conditions, explosions.
The coal sample, as received from the field, consists of 3 to 15 kg of material that first is reduced to a particle size of 2 to 4 mm (5 to 10 mesh) in a jaw crusher. This crushed material is then divided into three splits. The first split is forwarded to a laboratory for standard ultimate and proximate analyses.
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.

Bench scale laboratory tests were used to determine the effectiveness of gaseous, liquid and solid fire extinguishing agents. Liquid/ solid
Pulverizer housing or burner lines are glowing red; Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs." A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.
