• 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
