摘要： 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 including a burner main body having a peripheral wall and a bottom wall, at least one of the walls of the burner main body being formed with air intakes, an inwardly projecting flange provided on an upper portion of the peripheral wall of the burner main body, gas-air mixture tubes downwardly extending through the flange and arranged at a given spacing, a waste gas main pipe disposed under the burner main body, waste gas branch pipes extending upward from the waste gas main pipe, and gas nozzles mounted on the upper ends of the waste gas branch pipes respectively and positioned at the lower ends of the gas-air mixture tubes. The waste gas forced out from the nozzles ascends the interior of the mixture tubes along with the surrounding air and the gas-air mixture jets out from the tubes. When the mixture is ignited and burned, the swirling air currents produced above the flange support the combustion.

摘要： 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.

摘要： A ground flare comprising a furnace body in the form of a tubular wall having a circular or polygonal cross section and a bottom open over the substantially entire bottom area and a multiplicity of burners arranged at the opening of the bottom of the furnace body. Each of the burners comprises a gas nozzle and a gas mixing tube having an open lower end with the upper end of the gas nozzle positioned therein and a substantially cylindrical inner surface. Most suitably for the prevention of black smoke and vibration, the gas mixing tube has an inside diameter 2 to 5 times the inside diameter of the gas nozzle and a length 5 to 10 times the inside diameter of the tube. Flame transfer plates provided between the upper ends of the gas mixing tubes serve to greatly reduce the number of pilot burners which otherwise would be needed.

摘要： A conduit for feeding a combustible waste gas to a ground flare is divided into a plurality of branch pipes each connected to burners of the ground flare. A stop valve is mounted on each of the branch pipes except the first pipe and provided with a limit switch for detecting the closing of the valve. A pressure detector is mounted on each of the branch pipes except the last pipe. The valve on each branch pipe opens in response to an opening signal from the pressure detector on the preceding branch pipe and closes in response to both a closing signal from that pressure detector and a signal from the limit switch on the valve on the following branch pipe, whereby the number of branch pipes used for feeding the waste gas is controlled in accordance with variations in the feed of waste gas.
