Abstract
An apparatus for heating low rank coal having a processor with transverse baffles. Coal is introduced into the top of the processor and passes through the processor by gravity. Heated relatively inert gas is introduced into the processor and flows through the coal, heating the coal and removing moisture from the coal. The temperature of the heated process gas, the size of the coal, the size of the inlet and outlet openings of the processor and the rate of flow of the coal are selected for optimum efficiency.
