【考案の詳細な説明】 （産業上の利用分野） 本考案は、液体燃料特に灯油を気化させて燃焼させる
式の気化式燃焼器に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a vaporization type combustor that vaporizes and burns a liquid fuel, particularly kerosene.

よっても加熱されるようにしたものは知られる。(Prior Art) Conventionally, an electric heater for heating the liquid fuel flowing in the fuel supply pipe is provided in a part of a fuel supply pipe for supplying a liquid fuel to a burner to constitute a vaporizer, and the vaporizer is heated by fuel heat of the burner. Also known are those which are also heated.

気化部の温度を制御するようにしたものは知られる。In this type of vaporization type combustion apparatus, if the temperature of the oil supply pipe constituting the vaporization section becomes too high, fuel is carbonized in the oil supply pipe, which causes liquid clogging in the oil supply pipe. There is a defect. Therefore, it is known that the temperature of the vaporizing section is detected by a thermistor, and the electric heater is controlled thereby to control the temperature of the vaporizing section.
（考案が解決しようとする課題） しかし、該サーミスタは耐熱温度が低く、300℃前後

ーナの火炎が一定しないなどの不具合がある。(Problem to be Solved by the Invention) However, the thermistor has a low heat-resistant temperature, and cannot directly measure the temperature of the vaporizing portion, which is around 300 ° C. For this reason, it is necessary to detect the temperature of a relatively low temperature point remote from the vaporizing section to control the temperature of the vaporizing section, so that a response delay occurs in the detected temperature, thereby causing the fuel to evaporate. There is a problem in that a waving phenomenon occurs, and the flame of the burner burning in response to the phenomenon is not constant.
