COMPACT AUTOMATIC BURNER – With air and fuel valves mechanically linked and preset to maintain constant air/fuel ratio at all firing rates. FLOOR MOUNTED FAN – Delivers 100% of the combustion air required for burner operation, plus 20% excess air. CAPACITIES – 15 000 000 Btu/hr to 62 500 000 Btu/h HHV from one basic burner. Typical turndown ratio is 4 to 1. Greater hermal turndown ratios are available by operating with a lean air/fuel ratio at lower input rates. CONTROL VARIETY – Building from the basic burner package, three ratio control systems are available: pneumatic (standard), electric (optional), and electronic 8196, 8199, or 8386 Combustion Controller (optional).
RUGGED VERSATILITY AND RELIABILITY – An ultra-stable burner designed to operate with 20% excess air in chambers up to 2000°F and under negative or slightly positive pressures. Cold tight chambers present no problem for thisrugged, low maintenance work horse. Proven reliability while operating with natural gas, or any grade of commercial fuel oil, crude oil, pitch, or refinery bottoms. LOW NOx: By their design the package burners are inherently Low Nox. In conjunction with other NOx reducing features, they are capable of meeting emission limitations for new or retrofit applications in environmentally sensitive installations. However, emission levels will vary from one application to another. Contact your Fives North American Combustion, Inc. Sales Engineer for your specific application.
