Computational fluid dynamics (CFD) model for domestic biomass heating systems with a special emphasis on CO and CO₂ emissions.

The conversion of biomass is described using a bed model approach which is considered to be an arrangement of three layers: drying layer, pyrolysis layer and char layer.

The fuel release conditions are provided by these layers via a set of mixture fractions.

The model is applied to analyze the design of a commercial wood log stove with a nominal thermal capacity of 10 kWt.

The simulation results revealed a considerable potential for stove geometry optimization and emissions reduction.
