  • Reduction of PM emissions by highly oxygenated viscous biofuel [Elektronski vir] : use of glycerol in a micro gas turbine
    Seljak, Tine, strojnik ; Katrašnik, Tomaž
    The presented paper focuses on combustion analysis of a highly oxygenated and viscous fuel in an internal combustion micro gas turbine. The goal of the study is to investigate the benefits and ... challenges of utilization of such fuels in engines rather than in atmospheric combustion devices, what is currently the most common approach. While technical difficulty of the proposed approach is rather high, the environmental benefits in terms of NOx emissions and PM emissions are significant as concentrations of both species are significantly reduced and efficiency of conversion to mechanical work is significantly increased. Based on the analysis presented in the study, this effect is attributed to the influence of oxygen content in the fuel, which reduces the formation of NO due to lower nitrogen presence in the flame zone. This altered local air-fuel ratio also supresses soot formation resulting in significantly reduction of PM emissions. Besides these beneficial effects, the influence of highly oxygenated and viscous fuel is also perceivable through higher CO and THC emissions, however results indicate that increasing turbine inlet temperatures and fuel preheating temperatures could reduce also these two species without negatively affecting other pollutants.
