Abstract
The formation of NOx from combustion of biomass fuels has been
investigated. Samples of wood and straw with an average nitrogen
content of 0.04 and 0.4 % mass respectively were burned in a
laboratory scale batch fixed bed reactor at 570 °C and 832 °C. The
flue gas was analyzed for O2, NO, CO and CO2. High oxygen
concentrations in the feed gas resulted in significant non
fuel-NOx formation. Despite the large volatile content in biomass,
NO from char combustion can make up a significant fraction of the
total NO formed. The net NO formation increases with increasing
nitrogen content in the fuel and increasing O2 concentration, but
decreases with increasing NO concentration in the feed gas.
Moisture in the feed gas strongly reduces the overall CO outlet
concentration, but does not affect the NOx formation significantly.
