Abstract

In this work, a simplified description of combustion and nitrogen oxides chemistry based on 12 components was implemented in a 1.5D model framework with the aim to compare the results with ones earlier obtained with a detailed reaction scheme. Heterogeneous chemistry is given by the same models as in the earlier work but the homogeneous and catalytic reactions have been taken from other literature sources. A simulation of combustion of bituminous coal in the Chalmers 12 MW boiler is conducted and the results are compared with the results obtained earlier with the detailed chemistry description and with measured O2, CO, NO and N2O profiles. The simplified reaction scheme produces equally good results as earlier obtained with the more elaborate chemistry description.
