Abstract
A rotary coal feeder having a casing with a rotatable shaft having a plurality of blades defining pockets for feeding coal therethrough. The blades rotate about a hollow core and heated air passes through the core to keep the blades warm and prevent coal from sticking thereto. A chamber at the bottom of the feeder casing also has heated air passing through it to assist in drying the coal. The air exiting from the core and the chamber is directed into the coal stream.
