Ignition events remaining within the coal pipe created only weak pressure rise, while ignition events within a simulated pulverizer volume created explosions exceeding 70 bar gage (1015 psig). These experiments showed that explosion characteristics depend on dust concentration, ratio of pulverizer volume to coal pipe area, as well as coal type.
Explosibility of coal dust has been studied in laboratories, in explosion galleries and in an experimental coal mine. The data and results obtained from the tests showed that finely pulverized coal dust has a lower explosive limit of 0.035 to 0.08 ounces per cubic foot.
The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination. However, due to the flammable and explosive characteristics of pulverized.
To increase awareness of float coal dust explosion hazards in the mining industry. Background In underground coal mining, dust is produced at the face, at conveyors, at transfer points, and by the normal movement of workers and machines. The coarse coal dust particles settle rapidly. However, the fine coal particles remain airborne much longer, and.
The coal mill is operated as an air-swept mill and “blows” directly into the combustion zone of the steam boiler, via a pipeline connection. In case of an explosion, normally as consequence of ignition within the mill chamber, there will be explosion propagation towards the boiler. The combustion “cloud” will propagate to where it finds.

Ture easier to ignite and, once ignited, likely to detonate and cause an explosion. RECENT INDUSTRY TRENDS Industry trends which could increase the probability of fires and explosions in coal pulverizing systems are l. The increased use of coal by utilities which have no prior pulverized coal.
Dust explosion, static electricity, spontaneous combustion, and high-temperature materials passing through the filters can cause fire or explosion. The bag filters used for coal mills pose the highest fire or explosion risks in cement plants due to the minute size of the crushed coal. Electrostatic Precipitators. If coal dust or other explosive.
