Abstract
This paper discusses the development of user defined FLUENT™ sub models to improve the
modelling capabilities in the area of large biomass particle motion and conversion. Focus is put on a
model that includes the influence from particle size and shape on the reactivity by resolving intra-particle
gradients. The advanced reaction model predicts moisture and volatiles release characteristics that differ
significantly from those found from a 0-dimensional model partly due to the processes occurring in
parallel rather than sequentially. This is demonstrated for a test case that illustrates single particle
conversion patterns. The improved model will impact the simulation capabilities of biomass fired boilers
in the areas of thermal conditions, NOx formation and particle deposition behaviour.
