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.

Cyclone furnace

The present invention relates to combustion devices such as incineration furnaces and the like, and in particular, relates to combustion devices which include a combustion gas cooling device by means of which slag, combustion by-products and the like are rapidly cooled and thereby converted to nonadhering fly ash. By converting slag to nonadhering fly ash, the accumulation of slag in downstream exhaust processing equipment is diminished, and hence, the necessity of halting the operation of the combustion apparatus in order to remove the accumulated slag is eliminated, thereby improving the efficiency of operations.
