<p>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.</p> |
