ABSTRACT:
Apparatus and method for the pulverization and burning of solid fuels, such as coal, that provides for introducing relatively coarsely divided solid fuel into the lower part of an upstanding, closed housing for impact crushing therein, and for carrying the fuel fines upwardly through a turbulent zone defined in the housing between rotating spiders that include widely spaced radial blades that are oppositely angled to generate opposing air flows to further pulverize the entrained fuel fines autogenously by attrition. The entrained fuel fines in the rising column of air are then discharged from the housing into a burner for the pulverized solid fuel.
