Pulverise Boiler Coal Ball Tube Mill Explosion

Fire and Explosion Prevention in Coal Pulverizing Systems

2018-2-1  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
