NAO - Flare Pilots with Gas Burner Technology

NAO continued improving our pilot design, i.e., in the late 1970`s with a few simple advancements to our pilot windshield, we tested and proved our pilots rain and windproof for windspeeds of 250 MPH (400 Km/Hr).

Later work in steel plants (blast furnaces) and especially the coke ovens with their extremely dusty, dirty, sticky tar environment lead to further features to prevent "fallout" from fouling or plugging the pilot piping and venturi.  These new features added for the steel mills proved such an improvement that they were added to all flare pilots.

One example of NAO flare pilot performance was at a major refinery in Mexico, the plant had replaced their old "Brand X" flare tip with  a new NAO high performance smokeless flare tip with dual ignition pilots. When they started the ignition control panel for the first time, all three (3) pilots light up and were proven by thermocouples green lights in about 10 seconds.

The operators could NOT BELIEVE this speed, since the old "Brand X" flamefront ignitor took them several hours of adjusting the  gas/air and 3 ways valves to light the three pilots.  Since the plant was still shutdown for plant maintenance, one operator climbed to the top of the 225` tall derrick and confirmed that all the pilots were burning.  The plant has now added the dual ignition requirement to their flare specifications as a standard.

NAO flare  pilots are available in standard sizes and lengths of 1 1/4" diameter CONSERVATION PILOT, 2" diameter HEAVY DUTY PILOT and 3" HIGH CAPACITY or EXTENDED LENGTH PILOT with the venturi at distances of 400`.
