Abstract
A flare burner comprises a stack conduit, a plurality of gas distributing conduit extending radially from the stack conduit, and a plurality of gas supersonic gas nozzles connected to the gas distributing conduit. The stack conduit supplies flare gas to each of the gas distributing conduits, with gas communication therebetween. In one embodiment, the nozzles are directly connected to gas distributing conduit and in another embodiment the nozzles are connected to the gas distributing conduits via vertically extending burner conduits. The gas discharged through the supersonic nozzle flows at a supersonic velocity. The length of the burner conduits attached to the same gas distributing conduit becomes progressively shorter as the burner conduits are positioned further away from the stack conduit. In the embodiment where the nozzles are directed connected to the gas distributing conduits, the gas distributing conduits are angled and both ends of the gas distributing conduits are connected to the stack conduit to permit gas to flow from both ends.
