Design and Operation of a 6. 0 Inch Fluidized Bed Gasifier for Rice Hulls
This paper shows the performance and operating characteristics of a fluidized bed gasification reactor utilizing ground rice hulls as feed material. Basic experiments elucidating the thermochemical and fluidization characteristics were performed to provide data for the design and operation of a 6. 0 inch diameter gasifier. The reactor was constructed and tested. The product gas rate, the char and tar production rate and the exit gas composition were measured at various bed temperatures, rice hull feed rates and air velocity. The optimum operating conditions were obtained with reaction temperatures of 1300 to 1500 F, an air to feed ratio of 12 to 14 SCF per pound of rice hulls, a rice hull feed rate near 30 to 40 lbs/hr and a superficial air velocity of 2. 0 to 2. 5 ft/sec.
