<p>PURPOSE:To prevent the remained fuel in a fuel supply nozzle from being carbonized at the time of intermission of a burner device by cooling the top of the nozzle by air for a fixed time after the intermission of the burner device. CONSTITUTION:When a fuel pump 13 and an ignition plug 12 are operated by the operation of a drive circuit 21, a solenoid valve 16 is opened to operate a burner device 3. In a fuel supply nozzle 10 of the burner device 3, a fuel passage 9 is surrounded by a primary-air passage 22, which is opened to a discharge port 11 of the fuel passage 9 in its downstream end and connected to an upper- stream-side air passage 17 in its upper stream end. Besides, an air supply device 23 is provided to supply air to the top of the fuel supply nozzle 10 for a fixed time during the operation of an engine after the intermission of the burner device 3.</p> |
