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.
