Abstract

PURPOSE:To carry out the adjustment of combustion power by constituting an air circulation passage leading from the inner part of a with guide cylinder via the inner part of a combustion cylinder to a combustion chamber, and forcibly supplying air into the combustion chamber via the air circulation passage by means of a blower. CONSTITUTION:A blower 24 is activated by supplying power, air beneath a fuel storage tank 1 is introduced into a wick guide cylinder 2 via an air feed port 22 and air is forcibly supplied into a combustion chamber 15 from small holes 13 via an air circulation passage 18. When the rotational speed of the blower 24 is increased to increase the air flow rate under a combustive condition, the amount of air forcibly supplied into the combustion chamber 15 is increased, and a large amount of air is blasted to a wick 4. Thus, vaporization of the fuel is promoted, and the amount of a vaporized gas increases to form a strong combustion power. Further, conversely, when the rotational speed of the blower 24 is decreased to turn down the blast air flow rate, the amount of air blasted to the wick 4 decreases. Thus, the vaporization of the fuel from the wick 4 decreases to form a weak combustion power. In this manner, by controlling the amount of the blast air flow rate of the blower, the combustion power can be controlled rapidly and precisely.
