Self-Recuperative & Radiant Tube Burners
UNI-RAD® Radiant Tube Burner
Custom designed furnace burner with plug in reucuperator, custom designed for each customer application.
MAXON's UNI-RAD® Radiant Tube Burner produces an extremely stable and luminous flame that maximizes heat transfer throughout radiant tube furnaces. Flame ignition is maintained by a patented continuous spark system that ensures ignition each and every time without fragile, porcelain ignitors. This patented ignition system enables UNI-RAD® to pulse fire radiant tubes producing longer tube lives for reduced furnace ownership expense. Options are available to operate with preheated combustion air to 1200°F (650°C) to reduce your fuel consumption and operational expenses.
Features & Benefits: • Plasma Type Ignition: Unlike most spark ignited burners, the UNI-RAD Burner provides a zone of ionized air enriched with a small quantity of combustion gas to provide high energy ignition. • Annular Ignition Electrodes: The UNI-RAD Burner does not use a conventional spark plug; instead, the primary air and gas inlet tubes provide the electrical path for the ignition spark. This design feature provides many times the electrode area for extended life and positive burner ignition. • Adjustable Flame Length: The flame length may be tailored to your specific needs by changing the combustion air to ignition air ratios. This simple adjustment allows the burner to obtain optimum tube temperature uniformity over a wide range of firing rates and preheated air temperatures. • Wide Input Range: The unique design of the UNIRAD Burner allows it to operate over a large range of fuel gas inputs. Stability is maintained and flame length is controllable with firing rates ranging from as little as 80,000 Btu/hr input to as much as 700,000 Btu/hr. • Instantaneous Ignition: The burner’s continuous plasma spark provides instantaneous ignition allowing the burner to operate from the Duration Adjusting Type (DAT) output from a Proportional, Integral, Derivative (PID) Control Loop. Please note, continuous sparking is not mandatory with the UNIRAD Burner; intermittent sparking has been tested in several applications. When controlled using the appropriate valving, single point tube temperature variations may be reduced to as little as plus or minus 4° F (2.2°C). Contact Maxon for details. • Flame Supervision: The UNI-RAD Burner may be used in conjunction with IR or UV scanner flame supervision equipment. Contact Maxon for details. • Super Forced Cooling: In applications requiring rapid cooling, the UNI-RAD Burner has been used with secondary cooling manifolds to provide high rates of heat removal using conventional radiant tubes. The UNI-RAD Burner can sustain radiant tube pressure in excess of 10 PSIG (0.7 bars). • Radiant Tube Types: The UNI-RAD System is suitable for use on customer-supplied pressure tubes, negative pressure tubes, and electrified radiant tubes.
