Experiments were conducted on a triple swirler combustor at fixed atmospheric pressure. Firstly the triple swirler combustor model and experimental system were designed

and then experiments were conducted to study the effect of inlet airflow velocity

inlet temperature and fuel-air ratio on the combustion performance

including flow drag performance

ignition performance

lean blowout performance and combustion efficiency performance. Results show that: the triple swirler combustor can be ignited successfully and operated stably at all experimental cases

and inlet airflow velocity has little effect on the ignition performance; the total pressure loss coefficient increases with inlet airflow velocity increasing while the flow drag coefficient decreases non-linearly with the increasing of inlet airflow velocity

and the inlet airflow has not been at the full development state; as inlet airflow temperature increases

the ignition performance and lean blowout performance become better and the combustion efficiency improves.
