Fluidized bed gasification

The chapter describes the state-of-the-art of fluidized bed gasification of solid fuels, starting from the key role played by hydrodynamics, and its strong correlation with physical and chemical phenomena of the process and operating performance parameters of the reactor. The possible configurations of fluidized bed gasification plants are also assessed, and an analysis of the main methods for syngas cleaning is reported. Finally, the chapter describes some of the most interesting commercial experiences. The analysis indicates that the gasification of biomass and also of municipal and industrial solid wastes appear to be the most interesting sectors for the industrial development and utilization of fluidized bed gasifiers. © 2013 Woodhead Publishing Limited.
