ABSTRACT:
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.
