OSTI ID:5542157
An improved method is described for drying particulate low rank coal in a fluidized bed. The improvement comprises fluidizing the coal above a first portion of a gas flow distributor using a hot fluidizing gas and fluidizing the coal above a second portion of the gas flow distributor with a recycle gas stream at a temperature less than about 200/sup 0/ F. The second portion of the gas flow distributor is located near the coal discharge from the coal drying zone to cool overheated coal particles.
