Abstract
This paper reports the basic experimental result of counterflow diffusion flame in the microwave. Since flames contain ions and charged particles represented by soot, the flame interacts with microwave. The methane-air counter diffusion flame was formed in waveguide of microwave and effect of microwave on the flames was observed. Frequency of microwave is 2.45GHz and output of microwave generator ranges from 0 to 250 W. Application of microwave makes the flame intensity increase and the flame color change. These experimental results indicate that flame temperature increase with the application of the microwave.
