Like rotary dryers, fluidized-bed dryers are also used commercially. One of the distinguishing differences is that fluidized-bed dryers offer better heat transfer characteristics as a result of higher contact between the drying medium and coal, leading to lower energy consumption compared to a rotary drum dryer.
Nov 26, 2001· In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat required for the vaporization of the water. To promote gas–solid contact, most direct heat dryers have flights, placed parallel along the length of the shell, which lift solids and make them rain across the section of the dryer Fig. 1 ).
