Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

vertical mills, typically at the classifier outlet. Silowatch is used to monitor coal stored in silos and pulverized fuel bins. The detector monitors the carbon monoxide concentrations inside the mill, silo or bunker. A rapid rise in the concentration indicates combustion is underway, so preventative action can be taken before a fire starts or an

The wet coal is fed into a pulverizer along with hot gases drawn from the firing hood. The hot gas temperature is controlled by bleed air. The coal or coke is simultaneously dried and ground in the hot-air swept pulverizer. The pulverizer can be a hammer mill, ring-roll mill, or a ball mill type.

Coal Mill Safety. VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe.

Pulverized coal can be substituted for coke at nearly a 1:1 and can replace 25 - 40% of coke traditionally used in furnaces (USEPA, 1995). Pulverized coal injection is used world- wide to reduce coke use and, thus, coke emissions (Chatterjee, 1995). ' Pulverized coal injection may affect the final steel products.
