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

A Brief History of Dust Explosions ASTM International

(Although a dust explosion could have occurred several centuries earlier, for example in a boat transporting grain from Egypt to Greece, the first recorded dust explosion occurred in an Italian flour mill in 1785.) In Europe, coal mining became an important industry and the dangers from explosions of fire damp (methane) were quickly recognized.
