Lean ignition and blow-off behaviour of butyl butyrate and ethanol blends in a gas turbine combustor

This paper reports the experimental study on lean ignition (LI) and lean blow-off (LB) behaviour of butyl butyrate-based biofuels in a gas turbine combustor. The butyl butyrate-based biofuels were formulated (butyl butyrate–ethanol blends with the volume percentage of ethanol 0, 10%, 30%, 50% respectively, named BE-0, BE-10, BE-30, BE-50). The aviation kerosene RP-3 was also tested as a reference fuel. A combustor of an aero-engine was...
