Duct burners - LV AIRFLO® 4 - 21. 4 - 2 E - m - 11/10 Product description Series LV AIRFLO® principle 1) Fresh air 2) Gas 3) Hot air MAXON Series LV AIRFLO® burners are designed for heating process air in motion. An iron or aluminum bronze body which serves as the gas manifold is drilled to discharge the fuel gas between diverging mixing plates. The entire burner assembly is mounted inside a process air duct directly in the air stream being heated. [. . . ] Carefully controlled mixing plate aeration patterns give progressive mixing, superior cross-ignition and flame retention across the entire burner assembly length. The Series LV AIRFLO® burner burns clean and odor-free with low levels of NOx production. Correctly sized process air ducts and the resulting duct static pressure drop across the burner are the keys to successful operation. Normal capacities vary widely with the application and the duct pressures. The fuel used and the design velocities will affect the burner turndown. Modular design permits the burner shape and total heat release to match the application needs. Performance data varies depending upon temperature of air upstream and downstream of the burner assembly, the percentage of oxygen (by volume) in the passing air stream, and the allowable duct static pressure drop across the Series LV AIRFLO® burner. www. maxoncorp. com combustion systems for industry Maxon reserves the right to alter specifications and data without prior notice. All rights reserved. Duct burners - LV AIRFLO® 4 - 21. 4 - 3 E - m - 11/10 Available product sizes Several varieties of Series LV AIRFLO® burners are offered. The flame length and flame aspect are highly dependent upon factors such as process air velocity and process air oxygen content. Refer to "Specifications of LV AIRFLO burners" for more information. [5] Stated process air pressure drop across the burner should never exceed the specified range in this table. In some specific applications, the process air pressure drop range could be even more narrow. www. maxoncorp. com combustion systems for industry Maxon reserves the right to alter specifications and data without prior notice. All rights reserved. Duct burners - LV AIRFLO® 4 - 21. 4 - 4 E - m - 11/10 Applications Series LV AIRFLO® burners are designed for stable, efficient, raw gas operations in air streams with relatively low duct velocities. Duct static pressure drops may be as low as 0. 5 mbar or up to 6. 2 mbar. Elevated air stream temperatures approaching the Series LV AIRFLO® burner can be as high as 565° C. Reduced oxygen levels as low as 12% (by volume) are tolerated without a need to add primary combustion air. [. . . ] For applications with low oxygen levels, a partial premixture must be added through the system. Typical applications include thermal incinerators, cogeneration, spray dryers, hot air generators with variable flows, rotating drum dryers and calciners. 1) LV AIRFLO® burner 2) Combustion chamber 3) Gas pipe train 4) MAXON shut-off valves 3500 kW hot air generator with 9 ft LV-4D AIRFLO® burner to be used for the production of titanium dioxide www. maxoncorp. com combustion systems for industry Maxon reserves the right to alter specifications and data without prior notice.
