Description
This work presents the results of an experimental campaign investigating the behavior of an industrial burner operated with simulated Exhaust Gas Recirculation (EGR). EGR is recreated by diluting standard air with CO2, and tests are performed at ambient pressure using natural gas as fuel.
Burner characterization has been performed in terms of emission measurements both in standard conditions and with CO2 vitiated air. Flame topology has been studied with OH* chemiluminescence, evaluating the effect of fuel split and CO2 addition.
CO2 addition has been found to trigger thermoacoustic instabilities up to a certain threshold, therefore limiting the EGR operability window.
