Mill Inerting Systems Presentation to the ASBCUG

Mill internal temperatures are generally high enough somewhere to ignite any type ofcoal. Some bituminous coals ignite in the range of 315° to 350°F. All of these systems can be effective in reducing the risk of mill fire/explosion or limiting damage (explosion suppression systems). Each has strengths and weaknesses.

Coal pulverizer inerting and fire extinguishing system

In accordance with the mode of operation of such a bowl mill, the coal, which enters the bowl mill, is pulverized by virtue of the coaction of the grinding rollers with the grinding table. After being pulverized, the coal particles are thrown outwardly by centrifugal force whereby the particles are fed into a stream of air that is entering the bowl mill. The stream of air, which now contains pulverized coal particles,
