Abstract. A process is described for upgrading powdered coal to improve the usefulness thereof as a fuel for internal combustion engines which consists of: (a) pressure-leaching powdered coal having a particle size ranging from about 28 mesh to about 200 mesh in an aqueous caustic solution at a temperature ranging from about 175/sup 0/C, to about 350/sup 0/C., the amount of caustic in theGet Price
The hardgrove grindability index (hgi) is a widely used coalquality parameter with applications in coal mining, beneficiation, and utilization. an understanding of the petrology of the coal is fundamental to understanding the validity of the hgi in the given application. the hgi varies with coal rank, increasing (greater ease of grinding) with increasing rank through the highvolatile.
Pulverizers 101: part i. every coal pulverizer is designed with a particular fuel grinding capacity or throughput at a certain hardgrove grindability index (hgi), based on a defined raw coal.
