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.
