ABSTRACT:
A process and system are disclosed for drying coal in a fluidized bed wherein the heat necessary for drying is provided by partial combustion of the coal in the bed. Proper control of the reaction parameters, particularly reaction temperature, provides an acceptably high drying rate along with an acceptably low production of pollutants in the off-gases. A particular embodiment of the invention provides for cooling of the dried coal by mixing such dried coal with an additional stream or additional streams of undried coal.
