Abstract: PURPOSE: To surely ignite flame-retardant gas mixtures burner even when oxygen content in exhaust gas is small, by providing a baffle barrier at a specified distance measured from a nozzle's jetting port in nozzle's jetting direction of a fuel jetting nozzle, with the baffle barrier extending in the direction almost perpendicular to the center axis of the fuel jetting nozzle. CONSTITUTION: With the help of pilot flame in a first zone 2a, the gas mixtures in a second zone 2b in a combustion chamber burns with sure. The gas mixtures in the second zone 2b contains the exhaust gas of an internal combustion engine introduced through an inlet 10 as its main fuel. The oxygen content of the exhaust gas, the amount of exhaust gas, and the flow rate of exhaust gas fluctuate largely dependent on the operation condition of the internal combustion engine. A baffle barrier supports mixture of fuel and exhaust gas in the second zone 2b of the combustion chamber 2 by the turbulence of flow generated in the gas mixtures by the baffle barrier 5. During combustion operation of a burner 1, the baffle barrier 5 is heated red, and the heat radiated from the baffle barrier 5 increases inverse-flame ability of the flame at a root zone of the flame based on position of the baffle barrier 5. Thus, a stable flame is maintained even when the exhaust gas of low oxygen content comes in through the inlet 10.

Abstract: PURPOSE: To improve an ignition performance of a burner provided with an ignition device for a mixture air which is difficult to ignite such as an exhaust gas of an internal combustion engine by providing an auxiliary ignition device in which an air supplying device is connected with the ignition device. CONSTITUTION: A burner 1 for the combustible disposition of exhaust gases of an internal combustion engine whose oxygen content changes has a fuel supplying device 4 that has a fuel line and a fuel spraying nozzle and is provided with an auxiliary ignition burner 2 unitedly. The auxiliary ignition burner 2 consists of an ignition device 5, a fuel supplier 6 and a compressed air supplier 3 and the compressed air supplier 3 is installed at a vehicle compressed air system which has an air blower and so forth in a row. Fuel is supplied to each fuel supplying devices 4, 6 by an operation of a fuel pump 8 through diverged pipes and solenoid valves 9, 9a installed at a halfway of each divided pipes are controlled by a controlling device 7 together with the ignition device 5.
