pulverizer fire and explosions

The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fires. In most cases, pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air. Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire. The pyrite removal chute should be inspected often to ensure rejected material is removed from the under bowl area. Stoppage of pyrite chute flow can cause debris and-or coal to back-up into the primary air ducting.

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. Mill puffs most often originate in the under bowl area and can cause very destructive damage to the primary air ducting.

Mill puffs or explosions can be very dangerous resulting in serious damage to the pulverizer system or injury to personnel. When conditions that promote mill puffs are evident, personnel should promptly make correction actions and avoid the immediate area around the pulverizers.

Pulverizer airflow is adequate to facilitate stable transport of coal without settling in the burner line (>3,500 Fpm) but not excessively high to provide an abundant source of air for combustion in the presence of an ignition source. Ignition sources could be smoldering coal in the classifier, pulverizer or raw coal in the high temperature under bowl area.

All efforts must be taken to prevent coal from accumulating or settling in any of the pulverizer components. Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite. Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below the feeder are crucial. Hot smoldering or burner raw fuel anywhere in the pulverizer system is considered serious. Raw coal that is allowed to spill into the under bowl (air inlet) section and is allowed to accumulate will be exposed to high temperature (usually 500F or higher) and will eventually smolder and begin to burn. It is imperative that raw coal spillage into the under bowl area be prevented. When raw coal spillage is observed, immediate action should be taken.
