In practice, the more dangerous condition is an ignition source, i.e., a fire, within the coal pulverizing or conveying equipment. Fires are generally caused by accumulations of powdered coal brought to temperatures above their ignition temperature, either by hot air flowing over the deposit or by the deposit laying out on a hot surface.
Fire Fighting Coal Mill. Fire Fighting Equipment and Methods. The mine's fire prevention and fire fighting plan is designed to reduce the opportunity for a fire starting, and should one occur, to limit the extent of its destruction. The damage resulting from a fire can be minimized through adequate fire protection.
Since fire-fighting systems are so critical, the designs and arrangements of such systems should be carefully evaluated for compliance with the ABS requirements by the designer and ABS Engineering staffs. These Guidance Notes have been developed to assist in a better understanding of the ABS requirements for such

MILL COAL FEED IR BURNERS CLASSIFIER Figure 5 Ball Mills Suggestions for Enhanced Fire Detection on Double Ended Ball Mills The ball mill is a slow speed mill and has two primary areas where coal pockets can exist and create fires: the inlet/ outlet ductwork and the classifier. In a ball mill the raw fuel and the primary air are mixed prior
Fire fighting agents suppress fire by separating the liquid fuel from the air (oxygen) it needs to burn. ... cools, and insulates a fire. It is especially effective in fighting fires in coal mines, power generation (coal bunkers), tyre and rubber factories, timber mills, paper warehouses, structures and forest fires.
The EPRI project studied four fire detection methods: carbon monoxide monitoring, oxygen monitoring, temperature monitoring and infrared detection. Their performances are com- pared using the three basic mill systems. In addition, the effects of variations in operating conditions and coal reactivity are included. get price
