This report shortly describes the performed studies and the results of the project ‘Improved bio-CFD simulations’. The project objectives were to improve biomass particle conversion models such that they can be used in CFD calculations of biomass flames, and to provide better predictions of biomass particle conversion in PF boilers. Project activities have included development of biomass particle devolatilisation models, performing drop tube devolatilisation experiments with particles from 0.6 to 1.5 mm, performing a comparison of inflame measurements and CFD modelling of a 30 MWth wood bio-dust flame and conducting a short review of the industrial implications of the conducted wood particle conversion studies.
