Spray Combustion Characteristics and Emissions of Biomass Fast Pyrolysis Liquid (Bio-Oil) in a Swirl Stabilized Burner

Biomass fast pyrolysis liquid (or bio-oil) is a cellulose based alternative fuel with the potential to displace fossil fuels in stationary heat and power applications. To better understand the combustion behaviour and emissions of bio-oil, a 10 kW spray burner was designed and constructed. The effect of swirl, ignition source energy, atomization quality, air/fuel preheat and equivalence ratio on the stability and emissions of bio-oil spray flames was investigated. Since the fuel is not fully...
