Abstract
In a sloped tower type airborne drying and heating apparatus, a bulge or a neck is provided at at least one location in the inner wall of a sloped pipe for the purpose of reducing in a range of 3 to 50% the cross-section of a flow path in the pipe. Coal charged into the pipe is smoothly conveyed through the sloped pipe without dwelling in the lower portion of the pipe cross-section and thus effectively dried and heated.
