Abstract
A conventional pulverized coal-fired furnace is supplied fuel at two different levels. The raw coal is classified into a stream of relatively pure coal ground to conventional fineness for burners at the lower level, and a stream of very finely divided coal with a large, heavy mineral content for burners at the higher level.
