Fire and explosion protection of these coal grinding systems is challenging due to the high quantity of coal processed and the number of fire and explosion incidents per kiln in the 1990s was almost exactly twice that of the previous decade. ... (ES) Safe Fuel Grinding Safety considerations when purchasing a stand-alone coal mill grinding ...
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

In various industrial settings, such as coal grinding in cement plants, the risk of fires and explosions is ever-present. To mitigate these dangers, emergency inertisation is employed as a safety measure. This process involves introducing an inert gas into an enclosed potentially explosive environment to displace oxygen, thereby inhibiting the exp
