Abstract The use of biomass as an energy source is getting more attention not only as a renewable energy source but also for reducing the CO2 foot print of electrical energy production. One of the primary problems with utilizing biomass, in particular low grade biomass, in industrial processes is flame stabilization and burnout of the fuel. Biomass particles cannot be economically ground to the fine particle size typical of coal combustion, creating problems for conventional burners, such as biomass flame instability and incomplete combustion. Air Liquide/BYU is developing an oxy-enhanced biomass combustion technology that can improve biomass combustion performance by introducing oxygen to the burner without substantial geometric changes. The impact of oxygen injection in a swirl-stabilized burner on flame ignition and particle burnout was investigated by measuring LOI, flame imaging, flame intensity, and flame temperature. The results showed that a small amount of oxygen enrichment (less than 25% overall oxygen enrichment) can stabilize the biomass flame and produce ash closer to complete combustion. NO emission were also monitored and oxygen injection can be used to improve flame stabilization and burnout without increasing NO formation.
