PURPOSE: To permit stable combustion of fuel for a long period of time as well as suppress the formation and accumulation of tarry substances by a method in which metal oxides are adsorbed on part of a fuel vaporizing portion consisting of a porous material, e.g., ceramic fibers, etc., and the grain size of the oxides is made smaller than the pore diameter of the fuel vaporizing portion.
CONSTITUTION: A main wick 1 is made of a mixture of a ceramic fiber of a silica-alumina system, for example, and a polyacrylate, and an upper suction wick portion 2 connected to the lower part of the main wick 1 is made of a woven cloth of glass fibers, etc. Also, a lower suction wick portion 3 is made of a woven cloth of cotton, etc. In this case, metal oxides 5, together with anhydrous silicic acid, are dispersed and adsorbed in the fuel vaporizing portion 4 formed at the upper part of the main wick 1, and the grain size of the metal oxides 5 is made smaller than the main pore dieameter of the fuel vaporizing portion 4, whereby permitting the metal oxides 5 to be dispersed and adsorbed easily in the fuel vaporizing portion 4 and the capillary diameter of the fuel vaporizing portion 4 to be made smaller. Thus, fuel can be effectively sucked up to the surface of the fuel vaporizing portion 4.
