くる上で大きな貢献をなしている。 FIG. 5 is an enlarged sectional view of the heater 5 used as the air heating device shown in FIG. This heater 5 is composed of a heater element 18 whose main component is barium titanate, has numerous ventilation holes inside through which combustion air passes, has a thin electrode coating on the front and back surfaces, and has an electrode cover. It is fixed at 19. This electrode cover 19 is provided with a lead wire 20 that supplies electricity to the heater element 18, and heats the combustion air sent from the blower device 4. This heater element 18 has a property that its electrical resistance is small at low temperatures and becomes large at high temperatures.
Therefore, when electricity is applied to the heater 5, a large current flows because the electrical resistance is small in the initial stage, the temperature of the heater 5 rises very quickly, and the electrical resistance rapidly increases due to the temperature rise of the heat generated by the heater 5. Become. Therefore, when comparing the time required for the temperature rise of the heater 5 to reach its peak with a conventional heater, in the heater 5 of this embodiment, a large current flows at the beginning, so it rises quickly to a high temperature, and furthermore, when the temperature reaches a high temperature, the electrical resistance decreases. Since the temperature is large, it is difficult for current to flow, and since it has self-temperature control, there is no need to provide a temperature detection means for temperature control, making a major contribution to the creation of inexpensive and economical combustion machines.

ルギーに貢献できる。 FIG. 6 is a front sectional view of an FF type oil hot air heater showing another embodiment of the present invention. Combustion air is taken in from the blower 4 and sent to the heater 5 via the air supply/exhaust heat exchanger 21. The combustion air taken in from this blower unit 4 is heated indirectly (no mixing occurs) with combustion gas from the heat exchanger 9 which is discharged outdoors via the air supply/exhaust heat exchanger 21, and is further heated by the heater 5.
The impregnated body 3 is heated to a temperature of about 250° C. or higher to vaporize the kerosene, and when it passes through the impregnated body 3, the kerosene contained in the impregnated body 3 is vaporized and burned in the combustion chamber. The combustion gas is then discharged to the outside of the main body 6 through the heat exchanger 9, the heat exchange header 22, the heat exchange pipe 23, and the air supply/exhaust heat exchanger 21. This heater 5 is replaced by a heater element 18 whose main component is barium titanate as shown in FIG.
When combustion air heated by the air supply/exhaust heat exchanger 21 is introduced, the electric resistance value of the heater element 18 increases, the current value flowing to the heater 5 decreases, and power consumption is saved, leading to energy saving. . It also lowers the temperature of the combustion gas discharged from the air supply/exhaust heat exchanger 21 (increases the heat exchange rate).
This also increases the combustion efficiency of the combustion machine, contributing to energy savings.

However, metals such as nickel and iron, or those with a catalytic action by metal compounds thereof, are not preferred because they generate tar components. In this respect, alumina and silica are convenient because they are like catalyst carriers and have little catalytic action.

できる。 Furthermore, as shown in FIG. 10, if a fixing plate 28 such as a metal net is provided on the upstream side of the impregnated body 3 and the downstream side of the flame port plate 13, turbulence will be generated in the heated combustion air, causing impregnation. Since the body 3 is heated evenly, the kerosene contained in the impregnated body 3 is uniformly vaporized over the entire area of the impregnated body. Furthermore, a stable flame larger than the holes 17 of the flame port plate 13 can be formed downstream of the flame port plate 13.

When the impregnated body 3 is impregnated with electricity and the heater 5, which has barium titanate as a main component and has self-temperature control, is energized, the heater 5 rapidly reaches a high temperature and current becomes difficult to flow. Then, the combustion air is sent to the heater 5 by the blower 4, and this heater 5
Heat the kerosene to a temperature of about 250°C or higher to vaporize it, and then heat the flame port plate 13 provided at the same position as the hole 2 of the impregnated body 3.
through hole 17. When the heated combustion air passes through the impregnated body 3, since the impregnated body 3 is composed of fibers whose main components are alumina and silica, the bulk specific gravity and heat capacity are small, and the temperature of the combustion air is reduced. The kerosene contained in the impregnated body 3 is uniformly vaporized and ignited by the electrode 10 to burn without lowering the temperature. In the oil hot air heater shown in FIG. 2, the air and combustion gas heated in the combustion chamber are sent into the room by the heating fan 11 to heat the room.
