Abstract: A combustion supporting device is provided to use with a combustion furnace. The combustion supporting device includes a cone body, a tubular member, a frusto-conically shaped member, a base plate and a supporting portion. An upper end of the tubular member is connected to the cone body. The tubular member defines a plurality of gas holes around an upper portion thereof. The frusto-conically shaped member defines an insertion opening thereon. The diameter of the insertion opening corresponds to the outer diameter of the tubular member. A lower portion of the tubular member is passing through the insertion opening and received in the frusto-conically shaped member. The base plate defines a hole corresponding to the tubular member. The base plate is connected to a bottom of the frusto-conically shaped member. The hole communicates with a lower opening of the tubular member. The supporting portion is connected to the base plate.

Abstract: A combustion furnace includes an inner shell, an outer shell, a gas inlet piping and a flame inhibiting cover. The inner shell defines a receiving cavity therein. The inner shell defines a plurality of first gas holes around the periphery of a top portion thereof. The inner shell defines a gas inlet hole at a bottom thereof. The outer shell encloses the inner shell such that a gas flowing space is defined between the inner shell and the outer shell. The gas inlet piping has an opening formed at one end thereof, and the gas inlet piping communicates with the gas flowing space. The flame inhibiting cover is atop the outer shell and the inner shell, and a lower flange of the flame inhibiting cover is below the first gas holes.
