Abstract
The present invention relates to a vortex type furnace for burning powder. The furnace includes a first body, at least one air-supply pipe for generating a vortex, and at least one powder-supply pipe for feeding powder to be burned in said first body. The first body includes an elongated combustion chamber of a polygonal, elliptical, or circular cross section. The first body has an axis therealong, an ignition burner at an end thereof, and an exhaust port at another end thereof. The air-supply pipe generates a vortex around the center axis in the first body. The air-supply pipe, which opens at the internal peripheral surface of said furnace, is disposed quasi-tangentially or generally colinear with the internal peripheral surface of said first body. The powder-supply pipe, which opens at the internal surface of said first body, is disposed to be spaced apart from said air-supply pipe.
