SPECIFICATIONS
I ntegral fans provide 100% combustion air to these nozzle-mix burners. Oil atomizers are of the tip emulsion design, using steam or compressed air as the atomizing medium. Oil must be delivered to the nozzle at viscosities below 100 SSU.
Basic Light Oil Burner consists of the three basic sections described above, with the following equipment: a manually positioned and lockable firing rate control lever, a Sensitrol Oil Valve with linkage assembly, and a flange mounted oil atomizer assembly. Refer to Table 2 for oil and atomizing medium pressure/flow requirements. Specify this burner arrangement for oils up to and including #4 grade. Basic Heavy Oil Burner is similar to the light oil burner except atomizer, Sensitrol Oil Valve, and oil piping are sized and arranged to accommodate heavy oil or crude oil. Oil temperature is maintained electrically within the burner through four low wattage cartridge heaters: one within Sensitrol valve body, two in heater blocks attached to oil tube, and one in a heater block attached to the nozzle. The hinge assembly is fitted with a hot oil return valve (shown in the photograph). This burner is recommended for all heavy oils, including blended grades. Basic Dual-Fuel Burner is similar to oil burner except provision is made for burning either gas or a pre-selected grade of oil. A dual-fuel burner fitted for heavy oil permits use of any grade, ranging from diesel through very heavy #6. Flame Supervision and Control. There is a long list of optional accessories that can be added to the basic burners described above. In many applications of this burner, the combustion chamber is below 1400° F. Electronic flame supervisory systems are strongly recommended. Such systems are offered by North American and others. A specially designed system is available for boilers. Your local North American sales engineer can help select burner accessories required to make a firing system that will be reliable, efficient, and safe to operate.
The ruggedly constructed burners consist of three basic sections.
Front Section. A heavy cast iron mounting plate, with slotted mounting holes, fitted with a high strength castable burner tile rated for service up to 2600°F. A carbon steel or 304 stainless steel tile support jacket is available as an option. Center Section. A circular gas plenum with bottom gas inlet, a combustion air diffuser, a connection for a spark-ignited premix gas pilot (for natural gas or propane), and a threaded boss to accommodate a flame rod. Rear Section . Hinge-mounted includes blower motor, impeller, intake guard, a large reinforced glass observation port, provisions for mounting a flame detector, the flange-mounted oil atomizer, and the manual or motorized firing rate control. An accurate linked valve ratio control is provided by a compact arrangement of linkage rods and swivels that connect the internal main air proportioning shutters with a butterfly gas valve and/or a Sensitrol Oil Valve. Fuel oil enters the Sensitrol Oil Valve via a swivel type joint mounted on the hinge. Basic Gas Burner consists of the above three sections fitted with a manually positioned and lockable firing rate control lever (shown in burner photo) and a butterfly gas valve with linkage assembly. Refer to Bulletin 6140 for main and pilot gas accessories.
