ABSTRACT:
A method of drying wet coal fines smaller than 28 mesh in size employs both a vibrating fluidized bed type dryer and a coal fired burner for supplying hot drying gases to the dryer. A regenerative separator is interposed between the coal fired burner and the fluidized bed type dryer to satisfactorily remove particle matter from the gases without unacceptable pressure losses. Hot gases exhausted from the fluidized bed type dryer are also cleansed to remove particulate coal particles which are used as fuel for the coal fired burner.
