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

to a global coal production of around 3.7 Gt in 1999, coal use in power and heat stations amounted to 2.3 Gt whereas the non-metallic minerals industry, which includes cement production, used only about 0.5 Gt (IEA, 2001). The Clean Coal Centre has therefore published more reviews on power generation, including the co-utilisation of coal with other
