ABSTRACT:
A method and apparatus for drying wet coal granules or particles by introducing a liquid petroleum or coal derivative into the wet granular material, either before feeding into a dryer, or while it is fed, or at some point along the dryer cylinder embodying my prior patent 3,401,923. Thus the danger of explosion or obnoxious dust resulting from dry coal is eliminated and the calorific value of the coal is greatly increased. A modification of the air lock shown in my prior U.S. Pat. No. 3,401,923 is also made for improving the passage of heated particles into the housing.
