Coal

Coal is a hard rock which can be burned as a solid fossil fuel. It is mostly carbon but also contains hydrogen, sulphur, oxygen and nitrogen. It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.

DSS055: Coal Mill Safety In Cement Production Industries With Vincent

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.

Coal Mill

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.

Pulverizer Fire and Explosions

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

Raw Coal Spillage Or "Pyriting"

The sketch below illustrates the location where "throat" velocity must be 7,000 Fpm to prevent raw coal spillage. Pulverizer throats that are too wide will have a correspondingly low vertical velocity jet, which contributes to coal rejects and fires. Objectionable quantities of coal rejects are shown to the left.
