Fire Detection Methods for Coal Pulverizer Systems

produce smoldering fires. A major problem of grinding subbituminous coals is a high probability of burning coal being fed into the mill from storage. This event will upset detection devices and can be misinterpreted by operators. System configurations determine the devices that are necessary for proper fire monitoring of the pulverizer system.

Coal Mill - an overview ScienceDirect Topics

Mill outlet temperature control for bowl mill and tube mill. 5.1.4.1 Objective The outlet temperature of the coal mill is maintained at desired point so that the coal delivered from the mill is completely dry and achieves the desired temperature. Also, in case of high temperature at the mill outlet, cold air is blown in to reduce the risk of fire.

Pulverizer - Wikipedia

The pulverised fuel continues its journey towards the coal burners for combustion. The coarse particles rejected in the classifier are returned to the mill for another cycle of grinding. In order to avoid excess sweeping of coal from the mill, only part of the primary air, directly proportional to the boiler load demand, is passed through the mill.
