North American Oxy-Fuel Jet Burners
FUEL/OXYGEN REQUIREMENTS
The 5010-J burner is designed for glass and aluminum melter requirements of no water cooling and low oxygen supply pressures. Benefits of oxygen/fuel firing are faster melting, low NOx emissions, and smaller volume of combustion gas which permits a smaller bag house when required. There are two burner sizes: the -J1 has four different capacity nozzles available and the J3 size has 7 nozzles. OPERATION A high velocity luminous flame is produced by this concentric pipe burner. Fuel flows through the center passage while low velocity oxygen flows through the outer annulus. The fuel tube can be easily removed from the back of the burner for inspection. An oil model is available. The 5010-J burner dœs not have a standard pilot or spark electrode. The burner can be ignited with a torch or inserted when the furnace temperature exceeds 1400°F. FLAME SUPERVISION The burner has a rear connection that can accept a UV scanner. The connection is not available with oil models. Contact North American for application information. If a flame supervision system is not used, the burner should only be operated after the chamber temperature is above 1400°F.
Burner models operate on natural gas (5010-J) or oil (5011-J). Contact North American for oil model details. Required pressures for oxygen and gas are listed in the data table on page two. Because required oxygen pressure is so low, optional balancing orifices are requried to evenly distribute oxygen to all burners in a zone. Use of the orifice will raise required oxygen pressure to approximately one psig. MOUNTING The burner is available with either a fixed welded flange, or an adjustable set-screw held flange, for holding packing between the burner and furnace wall. The welded flange location should be specified at time of order. An optional mounting adapter allows angled or straight installation. Specify angle when ordering. COOLING REQUIREMENTS The burner is cooled by oxygen and fuel flows during operation. However, if the burner is going to be exposed to a hot furnace while not in operation, it must be pulled from the furnace. An air cooled mounting is available for special high temperature applications. Consult North American for details.
