Fuel gas production in a bubbling fluidized bed biomass gasifier

This dissertation combines the practical and theoretical aspects of atmospheric bubbling fluidized bed (BFB) biomass gasifiers through the integration of - operational experience from the gasification of thirty-nine biomass fuels (mono-fuels and mixed-fuels) using a laboratory-scale BFB gasifier, - a step-by-step design methodology of a BFB gasifier, and - a kinetic model incorporating both fluid dynamics and chemical reaction kinetics, which is validated with experimental data from BFB biomass gasifiers of different scales (laboratory-, pilot- and demonstration-scale). It provides a platform for an enhanced understanding of a sustainable production of hydrogen- and carbon-monoxide-rich fuel gases from gasification of woody and non-woody biomass in atmospheric bubbling fluidized bed gasifiers.
