In oxy-fuel combustion, pyrolysis is crucial for solid fuel conversion. This chapter presents experimental data on pyrolysis products from various biomasses (including minority species), forming one of the most comprehensive biomass pyrolysis data sets. Multiple setups (TG, fluidised bed, drop tube, heated strip reactors) cover a wide range of conditions, with design optimisations and discussions of advantages (e.g. reduced secondary reactions) and limitations (kinetics vs. transport). Since biomass is often modeled as cellulose, hemicellulose, and lignin, single first-order kinetics for these components under flash pyrolysis complement TG data. With walnut shells, superposition works only at slow heating rates, while higher rates demand extended modelling. Temperature strongly influences primary gas products, and residence time affects secondary distribution. The data also support more sophisticated kinetic schemes that describe the devolatilisation of biomass on the basis of its detailed chemical structure.

摘要

In oxy-fuel combustion, pyrolysis is crucial for solid fuel conversion. This chapter presents experimental data on pyrolysis products from various biomasses (including minority species), forming one of the most comprehensive biomass pyrolysis data sets. Multiple setups (TG, fluidised bed, drop tube, heated strip reactors) cover a wide range of conditions, with design optimisations and discussions of advantages (e.g. reduced secondary reactions) and limitations (kinetics vs. transport). Since biomass is often modeled as cellulose, hemicellulose, and lignin, single first-order kinetics for these components under flash pyrolysis complement TG data. With walnut shells, superposition works only at slow heating rates, while higher rates demand extended modelling. Temperature strongly influences primary gas products, and residence time affects secondary distribution. The data also support more sophisticated kinetic schemes that describe the devolatilisation of biomass on the basis of its detailed chemical structure.
