Description: As a renewable and environmentally friendly energy source, biomass and its combustion for heat and power generation are gaining an increasingly important role worldwide. The physical and chemical properties of biomass fuels are significantly different with coals, giving rise to challenges in design and operation of biomass-fired burners and boilers. The objective of this 3-day PhD course is to provide a presentation on biomass fuels: the combustion and modeling. The course will cover most of the key issues: (1) solid biomass feedstock & fuel analysis; (2) gas combustion chemistry and various tools for its analysis, from stoichiometry, equilibrium, kinetics to mixing; (3) traditional coal combustion – different conversion processes, main technologies, general modeling strategy and key modeling issues; (4) biomass fuels: differences with traditional coals and their implications in combustion and modeling; (5) different biomass combustion technologies used in the power industries (e.g., grate-firing and suspension firing): problems and solutions; (6) new sub-models associated with biomass combustion, e.g., advanced tracking of large, non-spherical biomass particles in suspension-firing furnaces, advanced modeling of intra-particle conversion processes in large, non-spherical biomass particles, deposition modeling; (7) computational fluid dynamics (CFD) modeling of biomass combustion in suspension-firing systems and in grate-firing systems: strategies and tips, cares to be taken, implementation of new models, etc.; (8) a number of demos, from fundamental chemical kinetic calculation to advanced implementation of new biomass-related sub-models in CFD simulation of complicated biomass combustion systems; (9) practice, test and demo of biomass combustion in a modern 400 kW grate-fired boiler test-rig. The course is aimed at recent graduates and professional combustion or power engineers who have but only have a limited experience in this field.
