Commercial Burners – Dual Fuel

Carlin Combustion Technology, Inc. the industry's technological leader in oil and gas, residential and commercial burners, controls and ignitors.

Commercial Burners – Dual Fuel

6.0 to 11.2 GPH Oil
840 to 1600 MBH Gas

 
The 702GO advanced combination gas/oil burner features Carlin’s adjustable combustion head assembly for unmatched fuel/air mixing, smooth light-offs and quiet running. The automatically-closed air damper and low-high-low step modulation improves efficiency by closer matching the output to the demand and reduces stand-by losses.
  • Simple adjustments of the air shutter and combustion head, set with Carlin’s easy-access screw adjustment.
  • Blower access cover allows full view of blower compartment.
  • Burners use the same air handling parts for all firing rates.
  • Burners use standard components, including Carlin electronic ignitor and standard primary controls.
  • Jacob’s ladder electrode tips for wide spark pattern and reliable ignition.
  • Low-high-low step modulation, using low-and high-fire oil valves and nozzles and butterfly gas valve with motorized air damper. Requires high fire control on boiler by others.
  • Positive ignition, stable operation, and compact flame. Gas pilot ignition for gas/spark ignition for oil.
  • Compact flame for maximum versatility.
  • Insensitive to draft or moderate back-pressure variations.
  • Can operate in forced draft applications up to 0.60 inches w.c. positive overfire pressure.
  • High resistance to pulsation.
  • Excellent performance when tested in appliances that do not use refractory combution chambers.
  • Rugged cast aluminum hoursing.
