化燃料と空気との混合促進を主とした絞り部５を配し。BACKGROUND OF THE INVENTION Conventionally, this type of oil combustor is a vaporizing cylinder made of a molded material in which a heater 4 for heating and vaporizing liquid fuel (kerosene, etc.) is embedded in a part of the cylinder with a bottom, as shown in Fig. 3. 1, a fuel injection nozzle 2 facing inward from the outside side of the vaporization cylinder 1, and a throat part 3 disposed on the concentric outer periphery of the nozzle 2 for ejecting combustion air. A constriction section 5 is arranged above to promote mixing of the vaporized fuel and air that have flowed in.
その上方に設けた炎孔部６により可燃混合気を燃焼に至

あった。From this configuration, when using liquid fuel such as kerosene, the vaporizer cylinder 1
A part of the heater 4 is equipped with a temperature detection element to control the heating of the heater 4 or to create optimal fuel vaporization conditions.For example, in the case of kerosene, it measures the temperature of the vaporization surface of the vaporizer cylinder 1 facing the nozzle 2 and the bottom surface near it. The temperature was controlled at around 250°C.
しかし変質化した灯油や、異種油混入の灯油を使用した
場合、２５０℃前後の最適条件では適正な気化が望めず
、タール化してしまう恐れがあるため２５０℃＋αとし
て、２８０℃前後でその対処を行なっていた。However, when using altered kerosene or kerosene mixed with different types of oil, proper vaporization cannot be expected under the optimal conditions of around 250℃, and there is a risk that it will turn into tar. was doing.

いる。A vaporizer tube 1 made of a molded material in which a heater 4 for heating and vaporizing liquid fuel (white kerosene in this example) is embedded in a part of the bottomed cylinder, and a side surface of the vaporizer tube 1 that faces inside from the outside. It has a nozzle 2 for ejecting fuel, and a throat part 3 disposed concentrically on the outer circumference of the nozzle 2 and ejecting combustion air, and one of the nozzles 2 is supplied with fuel by a pump,
A blower (not shown) is connected to one side of the throat portion 3. A constriction part 5 is disposed above the vaporization cylinder 1 to mainly promote mixing of the vaporized fuel and air that has flowed in, and the air mixture that rises through the constriction part 5 is directed by a rectifying member 7 made of wire mesh or punched metal. The flame flows through the central opening of the cylindrical flow divider plate 8 to the outer periphery and is combusted through the flame hole 6. A cap 9 is provided on the upper surface of the flame hole 6 to close it off.
また気化筒１の底面には本発明の銅系材料の金網１０が
備えである。なお、具体的には次のいずれかの構造を備
えている。Further, the bottom surface of the vaporizing cylinder 1 is provided with a wire mesh 10 made of a copper-based material according to the present invention. Specifically, it has one of the following structures.
（イ）銅系材料の金網１０を気化筒１の底面に載置する

However, since the kerosene particles that always hit the surface facing the nozzle 2 of the vaporizer tube 1 are prevented from suddenly scattering by the uneven surface of the wire mesh 10 on the bottom, they reach the flame hole section 6 through the constriction section 5 etc. and are burned. There is no occurrence of red fire.
