    Abstract
  • Combustion performance experiment was conducted for three-stage swirler of lean premixing and prevaporizing (LPP) low emission combustor with single dome. In order to investigate the effects of different fuel air ratios, inlet air mass flow rates, inlet air temperatures and positions of pilot atomizer on the combustion performance of combustor outlet, and the outlet temperature profile, combustion efficiency and pollutant emission rules of combustor were obtained. The experiment results show: (1) emission of NOx increases with the fuel air ratio increasing, and the combustion performance of dome A is better than that of dome B; (2) at the same fuel air ratio, if inlet air temperature increases or inlet air mass flow rate decreases, pollutant emission raises correspondingly; (3) position of pilot atomizer has effect on the combustion performance of LPP low emission combustor.
