An apparatus for incinerating a waste gas comprises a combustion furnace main body having a peripheral wall and a hearth and a plurality of flare burners disposed on the hearth. Each of the flare burners includes a burner main body having a peripheral wall and a bottom wall, a waste gas main pipe provided under the burner main body, water gas branch pipes extending upward from the waste gas main pipe and each having a vertical zigzag passage in an intermediate portion thereof, gas nozzles mounted in the upper ends of the waste gas branch pipes respectively and positioned inside the peripheral wall of the burner main body, a steam main pipe extending through the waste gas main pipe and projecting upward through the bottom wall of the burner main body, steam branch pipes extending upward from the steam main pipe, and steam nozzles mounted on the upper ends of the steam branch pipes respectively and positioned close to the gas nozzles. When the waste gas forced out from the gas nozzles is ignited and burned, the free carbon in the flame and the steam forced out from the steam nozzles undergo water gas reaction, permitting the gas to burn smokelessly.
