A plasma-assisted combustion (PAC) test platform for annular combustor fan-shaped test piece was developed to validate the feasibility of using PAC actuation to enhance annular combustor performance. Comparing experiments between conventional combustion (CC) and PAC were conducted where combustion efficiency, flue gas emissions, and outlet temperature distribution were measured. The performance of present method under different combustor excessive air coefficients were also evaluated. Compared with the test results of CC of fuel-rich, approximate stoichiometric ratio and fuel-lean kerosene/air mixtures, when PAC actuation was exerted with applied voltage of 10.1 kV, combustion efficiencies increased by 1.32, 1.52, and 2.03%, respectively; CO emissions reduced 43, 103, and 48 ppm, respectively; outlet temperature distribution coefficients decreased by 23.06, 22.04, and 11.46%, respectively; NO x emission from fuel-rich mixture combustion reduced 20 ppm, whereas it increased 41 and 5 ppm, respectively, for approximate stoichiometric ratio and fuel-lean kerosene/air mixtures; radial temperature distribution coefficients decreased by 25.71 and 22.50%, respectively, for fuel-rich and approximate stoichiometric ratio mixtures; however, it increased by 3.24% for fuel-lean mixture. The results lead to potential directions for the future optimization of kerosene-fueled aero-engine when using plasma-assisted combustion devices to enhance annular combustor performance.
