Computational Modeling of Nitric Oxide Formation in Biomass Combustion

Nitric-oxide formation from fuel-bound nitrogen in turbulent non-premixed flames was investigated. The calculations were performed using the k-epsilon model for turbulence and the Eddy Dissipation Concept for turbulent combustion in conjunction with detailed chemistry of the chemical reaction mechanism GRI-Mech 2.11. Comparison with experimental data from the literature showed that the discrepancies for integrated values were negligible, whereas the spreading of the radial profiles for nitric oxide was inaccurate. Furthermore, to illustrate the potential of the model, preliminary simulations of a wood stove were performed.
