The use of biomass and wood waste solids and sludges as fuel is often hampered by their low heating values and the presence of bound nitrogen that result in inefficient combustion and high NOx emission. Cofiring supplemental fuel through auxiliary burners helps with improving the combustion effectiveness and NOx reduction, but the benefits are limited to the fractional heat input of the auxiliary fuel. Demonstration tests have shown over 60% reduction in NOx, CO and VOC emissions, and a 2% increase in boiler thermal efficiency using only 8 to 13% natural gas
