Abstract

PURPOSE:To widen the breadth of adjusting the quantity of combustion and to improve assembly characteristic by providing a first flange substantially shielding by the bottom surface a flow control region formed between the first flange and an inner flame cylinder, and a second flange for dividing the flow control region into a plurality of parts and making the outer diameter of the second flange part larger than the outer diameter of the first flange part. CONSTITUTION:In a case where the exposure height of a wick 1 is lowered and the quantity of combustion is reduced, an unburnt gas which has flowed into an upper flow control region 22a is almost burnt by a flame supplied to a combustion chamber 8. Therefore, there are almost no unburnt gas components in the upper flow control region 22a positioned upward of the flame. Air discharged through air holes 11 and vent holes 13 which are located upper than the flame is clean, and the waste gas characteristic (CO/CO2) is not deteriorated. Accordingly, it is possible to turn down the quantity of combustion to a considerably lower value and this increases the combustion adjustment of width. Further, since the flange parts 21a, 21b and 21c of the flow control part 21 other than the lowermost stage flange 21a are set to have a diameter smaller that of said flange part 21a, the assembly work within the inner flame cylinder can be smoothly carried out.
