PURPOSE:To magnify ejection total areas and to effect vaporizing combustion effective ly for a large capacity of mixing gases by a method wherein heating of a vaporizing body is accomplished efficiently and exactly. CONSTITUTION:Forced air is sent to a vaporizing body 16 and an ejection chamber 11 and is pressed into a gas chamber 10 while it is ejected from an ejecting flame hole 7 and a sub-ejecting flame hole 19 into a combustion body 1; at the same time, other force air is ejected from the ejecting chamber 11 and a cold air ejecting path 17 toward a circular ignition wall 18. In case fuel oil is supplied to the vaporizing body 16, it is effused from a opening end part toward the circular ignition 18 and is ignited to effect unevaporating combustion. According to this method, the whole of the vaporizing body 16 comes to a vaporization generation temperature, whereby, the fuel oil supplied is evaporated and becomes the mixing gas with the forced air, thus, it is ejected by the ejecting holes 7 at constant pressure from the gas chamber 10 to burn. A part of the mixing gas is ejected and is burnt down from the sub-ejection flame hole 19 of the ignition wall 18 and the vaporizing body 16 is heated, therefore, the mixing gas is generated on a large scale continuously. The vaporizing combustion of the large capacity may be effected in the combustion board body 5 having many ejecting areas.
