Pilot Investigation on Mechanical Stirred and Pneumatic Drying of Bagasse with Boiler Flue Gases

Abstract:

A novel system of mechanical stirred and pneumatic drying of bagasse with boiler flue gases was developed and experimented on pilot scale in a sugar mill. Investigation was performed on factors affecting the dried bagasse moisture content, the drying efficiency of the dryer, and the pressure drops of both the dryer and the separating cyclone. Optimal operating conditons were found to be stirring speed 40 rpm, throughput of the pilot dryer 1000 kgh-1, and flow rate of flue gases 4500 kgh-1. The pressure drops of the dryer and the cyclone were less than 100 Pa and 250 Pa respectively. The novel system was superior to conventional dryers on both the drying efficiency and the power demand by the induced fan.
