Abstract:

The present invention relates to an apparatus for generating flames and more particularly to the microwave plasma burner for generation of high-temperature plasma flame by injecting gaseous, liquid or solid-powder hydrocarbon-fuels into plasma generated by microwaves. The invention provides a compact and portable apparatus for generating plasma flame. The apparatus includes a magnetron, an electrical power supplier, a waveguide system, a microwave power monitering system, stub tuners, a discharge tube, a gas supply system, a plasma ignitor and a fuel supply system. The method and apparatus is described for generation of a large volume of high-temperature plasma by injecting gaseous, liquid or solid-powder hydrocarbon-fuels into the microwave plasma torch to decompose the hydrogen and carbon containing fuels, and to mix the resultant gaseous hydrogen and carbon compounds with air or oxygen gas, instantaneously generating a large volume of high-temperature flames.
