Kerosene burner for home use boiler has the merit in economic cost. However, it is no easy to burn the Kerosene fuel as gaseous fuel. Therefore, Kerosene fuel is forced to heated or sprayed in order to vaporize and be mixed with the air. The heating type burner is superior to the other type burner, in the instant ignition, wide turn-down ratio, easy control of turn-down, and so on. On the other hand, the heating type burner consumes a lot of electric power during heating process ransing from 300 to 1000W.The objective of this research is to reduce the electric power for vaporing the Kerosene fuel during combustion by using strong thermal network in the burner. That is, a ceramic plate with very large pores to reflux the thermal radiation from flame upstream in order to vaporize the fuel. A burner with the ceramic plate was constructed, and the characteristics of the new-type burner were experimentally investigated.It is demonstrated as follows :(1) It has become possible to eliminate the electric power to heat and vaporize the Kerosene fuel during combustion.(2) The temperature difference across section become very small ranging within 30 degree K.(3) The ratio of reflux of heat from the flame after porous plate to the fuel seems to be 2 % of the total combustion heat.(4) The technique of ignition by using ultrasonic atomizer is promised to make ignition time short.

煤油燃烧器用于家庭使用锅炉的经济成本有价值。但是，将煤油燃料作为气态燃料并不容易。因此，煤油燃料被迫加热或喷洒，以使其蒸发并与空气混合。加热型燃烧器优于其他类型的燃烧器，在瞬间点火，宽的转下比例，轻松控制转盘等等。另一方面，加热型燃烧器在加热过程中消耗了大量电力，从300W到1000W。这项研究的目的是通过在燃烧器中使用强烈的热网络，以减少在燃烧过程中蒸发煤油燃料的电力。也就是说，一个带有非常大孔的陶瓷板，可以从上游火焰中流动热辐射，以使燃料蒸发。构建了带有陶瓷板的燃烧器，并对新型燃烧器的特性进行了研究。它被证明如下：（1）可以消除电力以在燃烧过程中加热并蒸发煤油燃料的电力。（2）（2）在30级范围内的燃料中的温度差异很小。 （4）使用超声雾化器的点火技术被承诺使点火时间短。
