Abstract
A liquid fuel combustion apparatus for evaporating and vaporizing kerosene, gas oil or like liquid fuel by heating, admixing air with the vaporized fuel in a specified ratio and burning the resulting gaseous mixture in a combustion unit. The vaporizer for the liquid fuel comprises a liquid fuel drawing-up member (15) made of a heat-resistant porous body (8) or heat-resistant inorganic fiber fabric (9) for drawing up the liquid fuel, and a heat generating member (6) including coating layers (22, 23) of heat-resistant metal, heat-resistant alloy or heat-resistant metallic oxide for giving heat to the drawing-up member. To prevent formation of tar-like substances, a catalyst is preferably deposited on the surface of the drawing-up member and/or on the surface of the heat generating member. Further preferably, the outer periphery of the heat generating member (6) is in contact with the drawing-up member (5). The apparatus assures stable combustion over a prolonged period of time and is useful as a heater, kitchen range or the like.
