Abstract

The characteristics of laminar premixed CH4CO/air opposed-jet flames are experimentally and numerically investigated. The premixed flames are operated at a fixed stoichiometric condition with various fuel mixtures of CH4 and CO. The flame structures are calculated using the SPIN code coupled with multi-component transport model and GRl-Mech 3.0 chemical kinetic mechanisms, while the PREMIX code is employed to investigate the laminar burning velocity. Results show that the measured and calculated flame front positions are in excellent agreement. The calculated flame structures suggest that the premixed CH4/CO/air flames can be categorized into CH4-like or CO-like flames, according to the spatial distribution of CO concentration. In addition, the calculated maximum laminar burning velocity of the premixed CH4/CO/air flames is found when the volumetric CH4 concentration is about 10-20% in fuel mixtures.
