| Research Abstract |
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.
