A process is described for upgrading powdered coal to improve the usefulness thereof as a fuel for internal combustion engines which consists of: (a) pressureleaching 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 the ...

  • A Comparison of Three Types of Coal Pulverizers

    A Comparison of Three Types of Coal Pulverizers

    As the flat grinding table rotates, coal is gradually forced out towards the edge where it passes underneath the rollers. When the ground material leaves the edge of the table, it is met by an upward high velocity stream of hot primary air which then dries and carries the pulverized coal through the classifier. Properly sized product leaves the mill and is transported through coal .
