ABSTRACT:
A gas flare is described which includes a vent stack for combustion air having a first end and a second end. A gaseous fuel cyclone chamber surrounds the vent stack. The cyclone chamber has an interior wall conterminous with the vent stack and an exterior wall spaced from the vent stack. The cyclone chamber has a narrowing defining an access opening adjacent the first end of the vent stack. A gaseous fuel injection ring surrounds the first end of the vent stack with fuel nozzles extending into the access opening of the cyclone chamber. Gaseous fuel is fed into the cyclone chamber for thorough mixing prior to combustion. An igniter is positioned above the first end of the vent stack. Gaseous fuel flowing under pressure from the cyclone chamber creates a venturi effect drawing air up the vent stack to form a mixture of air and gaseous fuel which is ignited by the igniter. A combustion air passage communicates with the second end of the vent stack. The combustion air passage follows a circuitous route passing along the exterior wall of the cyclone chamber adjacent the first end of the vent stack such that cool combustion air passing through the combustion air passage draws heat from cyclone chamber to reduce heat build up adjacent the first end of the vent stack.
