Drying, devolatilization and char combustion of a single highly wet biomass particle in a fluidized bed has been studied. In the present work three different biomass fuels are considered including bagasse, manure and robinia. An experimental program has been carried out using a bench scale fluidized bed combustor. The combustor is made of quartz glass, which is electrically heated. Duration of volatiles release and that of char combustion have been recorded by nicked eye and gas analysis. The effect of operating parameters (bed temperature, fuel particle size, oxygen concentration) and particle characteristics has been investigated. A simplified mathematical model of heat-transfer controlled pyrolysis has been developed to understand the experimental date. The model predictions are in a good agreement with the experimental results. The model can be used to estimate the devolatilization times in other combustion systems. Kinetic parameters of char combustion are obtained, based on the measured burnout times and simple model considerations.
