Fuel diversity and reduction in pollutant emissions are driving the increased utilization of CO2 neutral biomass. Effects of operating conditions, such as bed temperature; excess air ratio; and secondary to primary air ratio on emissions of NOx, SO2, and CO for burning different blends of wheat straw and Salt Range coal under fast fluidized bed conditions in a pilot scale test facility, are reported in this study. Emissions of NOx were found to decrease with an increase in wheat straw ratio and secondary to primary air ratio. SO2 and CO emissions were observed to decrease with an increase in excess air ratio and wheat straw ratio.
