Detailed Chemical Kinetics Modelling of NOx Reduction in Combined Staged Fuel and Staged Air Combustion of Biomass

E. Houshfar, T. Løvås & Ø. Skreiberg
Fuel and air staging are used to study the potential for reduction of NOx emissions from biomass fuelled reactors. The two well-known methods to reduce NOx emissions in a combustion process by primary measures are air-and fuel staging. Air staged reactors use primary air injection in the fuel bed, and a secondary air injection in the combustion chamber. A rich combustion in the first stage (close to stoichiometric condition) gives the maximum conversion of fuel-N...
