The burning techniques are used in numerous regions from the heating furnace, the gas turbine and the boiler to the small burning receptacles. Retaining stable combustion is an important burning technique for using effective energy. In recent years, it is reported that a small flame (which is called micro flame) is formed on the tip of nozzle in atmospheric pressure. This flame has some characteristics of combustion that are different from the ones of conventional diffusion flame. On the other hand, the combustion method using the low temperature plasma at atmosphere pressure attracts attention and has been studied. It is reported that the optical emission measured at the discharge area between the electrodes shows that the plasma has CH radical. It is possible to enhance plasma-assisted combustion with these radicals. In this study the micro flame for methane, hydrogen and fue gas diluted with nitrogen is formed by using the burner nozzle whose various inner diameters are less than 1mm. for diffusion combustion, premixed combustion and plasma-assisted combustion. The flame configuration and the stability limit of diffusion combustion are compared with these of plasma-assisted combustion in the case of micro flame.
