Abstract:
A burner assembly comprising an outer tubular member, an inner tubular member extending within the outer tubular member to define a flow passage, an inlet located at one end of the flow passage for receiving fuel into the flow passage, an outlet located at the other end of the flow passage for discharging the fuel, a splitter disposed in the flow passage for splitting up the fuel discharging from the outlet so that, upon ignition of the fuel, a plurality of flame patterns are formed, an enclosure extending around the outer tubular member and having an inlet for receiving air, the enclosure directing the air towards the outlet for mixing with the fuel discharging from the outlet to support the combustion, and a vane supported on the outer tubular member for stabilizing the flow of the air, the vane comprising a frustro-conical wall tapered radially inwardly in a direction towards the outlet so that a portion of the air impinges on the inner surface of the wall, the vane being spaced from the outer tubular member to define an annular gap therebetween so that a portion of the air passes through the annular gap and impinges against the vane before passing towards the outlet, and so that the remaining portion of the air passes from the register, over the vane and towards the outlet.
