초록 ▼

A burner assembly is provided for combining oxygen and fuel to produce a flame. The burner assembly includes a burner block including a combustion chamber and a nozzle discharging an oxygen and fuel mixture into a first stage region formed in the combustion chamber. First stage oxygen is supplied to the first stage region in the combustion chamber to combine with the oxygen and fuel mixture discharged into the first stage region by the nozzle. Second stage oxygen is also delivered to a downstream second stage region in the combustion chamber in sequence through an oxygen delivery tube, a flow regulator plate, and then an oxygen-conducting passage formed in the burner block. The flow regulator plate has a fixed-diameter oxygen-flow orifice having an internal diameter that is less than the internal diameter of the oxygen delivery tube to meter the flow of second stage oxygen discharged into the second stage region so as to apportion oxygen flow between the first and second stage regions.

A burner assembly for combining oxygen and fuel to produce a flame, the burner assembly comprising a burner block formed to include a combustion chamber having an inlet opening and an outlet opening, a plurality of oxygen-discharge ports around the outlet opening of the combustion chamber, and oxygen-conducting means for conducting oxygen through the burner block outside of the combustion chamber to the plurality of oxygen-discharge ports, a nozzle including means for discharging an oxygen and fuel mixture into the combustion chamber formed in the burner block, means for fixing the nozzle adjacent to the burner block to position the discharging means at the inlet opening of the combustion chamber so that a primary combustion zone is established in the combustion chamber between the inlet and outlet openings, means for supplying oxygen to the combustion chamber through the inlet opening so that the oxygen supplied by the supplying means mixes with the oxygen and fuel mixture discharged by the nozzle in a first stage region inside the combustion chamber to produce a combustible mixture that can be ignited to define a flame having a root portion in the combustion chamber and a tip portion outside the combustion chamber, and means for delivering oxygen into the oxygen-conducting means formed in the burner block so that it passes through the oxygen-discharge ports and is ejected into a downstream second stage region containing a portion of the flame and lying outside the combustion chamber to supplement oxygen supplied to the first stage region inside the combustion chamber by the supplying means, the delivery means including at least one oxygen-delivery tube formed to include a passageway therein communicating oxygen into the oxygen-conducting means formed in the burner block, the at least one oxygen-delivery tube having a first internal diameter, the delivery means further including a flow regulator plate formed to include a fixed-diameter oxygen-flow orifice having a fixed second internal diameter less than the first internal diameter the flow regulator plate being positioned relative to the at least one oxygen-delivery tube and with its orifice sized to regulate oxygen flow through the fixed-diameter oxygen-flow orifice with respect to the flow through the oxygen-conducting means formed in the burner block.
