DSS055 Coal Mill Safety In Cement Production Industries

Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill which therefore needs to be explosion pressure and shock-resistant. NFPA requires coal mills to be good for 50 PSI.

Fire Detection Methods for Coal Pulverizer Systems

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 to entering the mill and initial drying of the surface moisture is completed. With this condition AT monitor-

Mill Inerting and Pulverizer/Mill Explosion Mitigation

flaming smoking or smoldering coal inside the mill means a mill explosion could be occur at any time. • Any burning or smoldering material inside the mill can evolve into an explosion because they provide an ignition source if the air to fuel (coal) ratio is elevated or higher than desired.

Fireproof and explosive-proof measures for coal grinding mill

2. Pulverized coal would be transformed into explosive compound while hovering in the air for long. The explosion limit varies from coal by coal. The lowest limit is 45g / m3 and the highest limit is 2000g / m3 which is quite large. The explosion is strongest when the intensity is at 300 400s / m3.

Fire and Explosion Prevention in Coal Pulverizing Systems

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
