Reducing the Fuel-Bound Nitrogen Conversion to NO in an Air-Staged Combustion of a Synthetic Biomass-derived Gas

B. Adouane, W. De Jong, J.P. Van Buijtenen & G. Witteveen
Fuel bound nitrogen (FBN) content in the biomass-derived LCV (Low Calorific Value) gas compromises the neutral aspect of biomass gas regarding CO2 emissions. These because the FBN once in the combustion chamber will mainly form NO. Many approaches are applied to reduce the conversion of FBN to NO; these approaches could be applied upstream of the combustion chambers, like wet scrubbing or downstream using selective or non selective catalytic reduction, or optimizing the combustion process...
