the waste gases from ESP to rotary kiln is a fluidized bed dryer, a gas-gas heat exchanger for preheating feed coal and air a return duct to carry the waste gases back to chimney. Design of fluidized bed dryer using CFD (ANSYS) is proposed in this present work.
Thermal coal dryers and drying systems utilizing vibrating fluid bed units Conventional (Non-Vibrating) Fluid Bed Thermal Dryers with In-Bed Heat Exchangers Conventional fluid bed thermal dryers with in-bed heat exchangers are used for increased thermal input, for higher evaporative
The fluid bed dryer has been designed for the specific requirements of drying a 6 mm x 0 (¼" x 0) feedstock of anthracite culm and occasional intermittent feeds of anthracite silt. The feed moisutre of the culm ranges between 16 and 18 per cent by weight and is approximately 24 per cent for the silt.
ized unit operations with few difficulties. Most fluidized-bed combustors and fluidized-bed pyrolysis units use coal powders with Group B characteristics. Slugging occurs when the walls of the fluidized bed stabilize the bubbles such that the bubbles push the solids upward in the unit. Group B …
