Abstract

An experimental study was performed to investigate the stabilization mechanism of inner flame in a double-flame cooktop burner. Several hypotheses were made on CO emission and unstable mechanisms, such as concentration and flow effects. Flow characteristics and flame structure were observed by PIV (Particle Image Velocimetry) and OH PLIF (Planar Laser Induced Fluorescence) measurements respectively. We also could found that internal recirculation of exhausted gases and flow dynamics such as turbulent intensity, strain rate and vorticity were very important in stabilizing the inner flame. To design the high-efficiency and environment-friendly double cooktop burner, CO emission and thermal efficiency must be optimized under circumstances such as regulation limits, customer’s needs and so on.
