    Abstract
  • Experiments were conducted to study the combustion performance of a triple swirler combustor with no dilution holes at different inlet airflow velocities and fuel-air ratios. The results show that the ignition fuel-air ratio increases from 0.0115 to 0.0174 with the growing inlet airflow velocity, while the lean blowout fuel-air ratio varies little and most of these values are below 0.005; at the same fuel-air ratio, the slower inlet airflow velocity means the higher combustion efficiency; the combustion efficiency is above 0.895 at all experimental conditions, and the outlet temperature distribution factor is about 0.1 at the state of high fuel-air ratio; in full consideration of all combustion performance, the experiment results have proved the feasibility of canceling dilution holes for high fuel-air ratio combustors and several technology innovations mentioned here in.
