  • 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 …

  • COAL HANDLING SAFETY

    removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted. The Millwatch system is installed near the classifier and can detect the CO emitted from any hot inclusions within the ...

  • Fire and Explosion Prevention in Coal Pulverizing Systems

    Industry trends which could increase the probability of fires and explosions in coal pulverizing systems are: l. The increased use of coal by utilities which have no prior pulverized coal experience. 2. The increased use of lower rank, higher volatile content coals. 3. The increased use of control room electronic data gathering and retrieval systems which display only digital, rather than ...

  • Coal dust - Wikipedia

    Coal dust suspended in air is explosive—coal dust has far more surface area per unit weight than lumps of coal, and is more susceptible to spontaneous combustion. As a result, a nearly empty coal store is a greater explosion risk than a full one. The main attempts at prevention include using safety lamps, adding stone dust coffers to mine galleries to dilute the coal dust, watering workings ...
