Full conversion of 500 kW pulverized coal rig to 100% torrefied biomass firing.. Torrefied biomass combustion slower, may lead to higher gas exit temperatures. • Cofiring at 50% thermal share reduces SO X and NO X substantially.. Airstaging will reduce NO X during (co)firing of torrefied biomass even further.. Smart biomasscoal blends will ameliorate operational issues such as slagging.
