A Novel Burner for Investigating End-Gas Effects of Transient Flame-Wall Interaction

Abstract

This paper presents the progress of the characterisation of a novel burner to investigate exhaust carbon monoxide emissions from premixed flames undergoing quenching and transient flame-wall interaction. The axisymmetric, atmospheric, fully premixed, forced laminar burner is designed to investigate the quenching behaviour as the flame oscillates. A speaker in the plenum induces these oscillations, and a cooled central tube quenches the inner portion of the flame. An emissions bench is used to accurately measure the end-gas CO and other species of interest. This enables systematic investigation of the contribution of CO emissions produced as a result of transient flamewall interaction, relati..
