Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill startup, 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

Davis and Orban (1995), in a study of low and high volatile bituminous coals, attributed the segregation to both rank (and inherent HGI) differences and to the grinding behavior of the maceral assemblages, independent of coal rank. Mill power consumption in blends tends to follow the power consumption for the harder coal (Conroy et al., 1989).
