In this paper, a microwave plasma burner for generating an enlarged high-temperature and large-volume plasma
flame by injecting methane gas into the microwave plasma
torch was presented. The air microwave plasma torch explosively
burned out the hydrocarbon fuel by high atomic oxygen density.
It was observed that the volume of the plasma-burner flame was
more about ten times than that of the plasma-torch flame, showing
an expanded burner flame.
