Gasification characteristics of biomass wastes in fluidized bed gasifier

With high efficiency and compactness, the circulating fluidized bed (CFB) gasifer has become more important and promising. Several kinds of biomass waste have been experimented with on the bench-scale CFB gasifier. Study focused on the gasification characteristics of biomass wastes in CFB. It has been found that temperature of the gasifer is determined by the equivalence ratio (ER) and that the composition of fuel gas varies with the ER. The product gas is influenced by a second reaction and residence time. The experimental results also indicate that the CFB gasifier is suitable for different kinds of biomass and can operate over a broad range of operating conditions.
