PURPOSE: To provide a burning device having a wide burning control range and excellent comfortableness by means of promoted fuel mixing to shorten and make uniform the length of final fire flames by a method wherein air supply at the final burning stage is distributed in two stages nd supplied uniformly and a high velocity air is mixed with unburnt gas rising up in the upper part of a burning chamber.
CONSTITUTION: Air flowing from a secondary air hole 14 and being indicated by the arrow a1 is first mixed with unburnt gas rising up in a burning chamber 8 and next, a sufficient amount of air flowing from an air hole 13 through a stream smoothening cylinder 15 as indicated by the arrow a is supplied from the gap between the upper end of the cylinder 15 and a flame smoothening plate 16. Air supply to the fire flames f is distributed in two stages as indicated by the arrows a1 and a2 and air necessary for burning is able to be sufficiently supplied and mixed. Further, as the upper part of the cylinder 15 is projecting above the chamber 8 at the outside of an inner flame cylinder 6, a high velocity air is able to be mixed with unburnt gas rising up in the upper part of the chamber 8 and promoted fuel mixing enables the final fire flames f to provide stabilized blue flame burning and hence, the length of the flames f is able to be shortened.
