Abstract In this study, a 60 kWth capacity swirl stabilized fuel flexible combustor utilizing flow-blurring injector is developed for industrial applications, by scaling-up a small scale system that has been produced and experimentally tested by our research group. A major advantage of the novel combustor is that it can efficiently and cleanly burn nontraditional fuels such as glycerol. The combustor development process was conducted in three stages. In the first stage appropriate criteria were selected to design and manufacture the liquid fuel injector, swriler and combustion enclosure. In the second stage, experiments were conducted to investigate combustion performance with diesel and vegetable-oil. Flame photographs and emissions measurements showed robust performance characterized by blue flames, and stable combustion with low emissions. In the third stage, experiments were conducted to investigate combustion of glycerol fuel. Results show a general trend of lower CO and NOx levels at higher ALRs, replicating the performance of the small scale injector. Most importantly, clean combustion of fuels with widely different physical and chemical properties has been demonstrated in the same system without the need for costly upstream fuel-processing steps.
