Abstract

This research project focused on the study of the fluidization characteristic of biomass in a 0.28m-ID Plexiglas circulating fluidized bed. The velocity distribution and voidage distribution under fast fluidization were examined. The performance of a 1 MWe Circulating Fluidized Bed Gasifier (CFBG) for power generation, in operation in Jiedong City, Guangdong Province, China, with a diameter of 2.0 m and a total height of 8.5 m, was also analyzed. The operation temperature was found to have a strong impact on gas efficiency, conversion of carbon, gas productivity, and gas composition. About 60.1-81.8% gas efficiency and 56.2-92.7% carbon conversion can be achieved when the temperature was about 630-1042 for sawdust. The successful operation of the 1 MWe CFBG demonstration plant for power generation showed CFB as a reactor for biomass gasification presenting a bright future.
