Abstract
A method and apparatus for drying solids such as bark, peat, wet coal or the like utilizes waste heat recovered from a rotary kiln. Solids are dried by simultaneously using both the radiation heat of the shell surface of the kiln and the heat of hot flue gases being discharged from the kiln. The solids are dried in a drying space which is defined by the shell surface of the rotary kiln and a jacket surrounding at least part of the shell surface of the kiln. Flue gases from the rotary kiln are passed with solids through the drying space. The kiln may be used for combusting lime.
