ABSTRACT:
There is disclosed a combustion apparatus of a fuel vaporizing type wherein fuel is led to a fuel injector for vaporization and the vaporized fuel is fed to a burner via a gas nozzle for combustion. The combustion apparatus features the provision of a device for removing at a high temperature tar attached in the fuel injector. Preferably, the removal of the tar is accomplished by fuel-empty burning. Therefore, there is no possibility that tar is deposited in the fuel injector, resulting in no faulty or incomplete combustion nor an accident to the combustion apparatus. It is further unnecessary to exchange the fuel injector or a vaporizing core installed therein or clear the interior of the fuel injector. The combustion apparatus demands only the fuel-empty burning device for the removal of tar with high temperature heating and is of simple and low cost structure. Controls are further provided for keeping constant the temperature of the fuel injector during fuel-empty burning. This provides an effective way to avoid an overheated state of the fuel injector itself and destruction of a heater or other constituting components, ensuring power savings in empty-free burning.
