A preliminary study on the criterion for opposed jet flame stabilization is reported. The experimental investigation consists of the measurement of flame blowoff by means of premixed lean liquefied petroleum gas and the temperature distribution. The criterion for flame stabilization has been obtained. It is correlated with main stream velocity V _m, mass flux ratio of jet to main stream F , internal diameter of jet nozzle d _J and equivalent ratio of fuel-air Φ . The stabilization character of opposed jet flame is described as a well-stirred reactor, and the critical zone acts as a strong ignition source to maintain flame stabilization. A criterion for flame stabilization by theoretical analyses is in good accordance with experimental results.
