PURPOSE:To freely control the rate of consumption of kerosene from the maximum heating output time to the minimum output time immediately before extinguishing of flame, without generating soot or offensive odor, by providing a metallic wire, of which temperature of oxidative-catalytic action is comparatively low, between the inner and the outer cylinders of a kerosene stove. CONSTITUTION:A metallic wire is fitted to the lower part of a combustion cylinder in such a manner that the ventilating resistance is comparatively small, heating capacity is small, the wire is not directly contacted with an inner and an outer cylinders, and heat transfer loss is small. The wire is made of an alloy, such as nickel, chrome, iron, copper, or the like, of which temperature of oxidative-catalytic action is comparatively low. Single alloy wires of comparatively small diameter, twisted into a stranded wire, rolled up to a coil of which external diameter is about 50-70% of the distance between the inner and the outer cylinders, stretched out into the shape of a ring with pitches of 5-10mm., is fitted to the lower part of a combustion cylinder with a nichrome wire, or the like, being not closely contacted with the external surface of an inner cylinder. With such an arrangement, the consumption rate of kerosene can be controlled freely from the maximum heating output to the minimum immediately before extinguishing of flame, without generating soot or offensive odor, in a kerosene stove. |
