User manual MAXON LV AIRFLO M BULLETIN

[. . . ] Low air stream oxygen levels can be tolerated without a need to add primary combustion air to the system. Modular burner design provides burner assembly configurations and total heat release for maximum application flexibility. [. . . ] LV-NP1 AIRFLO® burner with its gray iron body and #321 stainless steel mixing plates is the most economical choice for a raw gas burner system for fresh air heating with low heat release per lineal foot and outlet temperatures up to 540°C. LV-3G AIRFLO® burners have gray iron bodies and #321 stainless steel mixing plates. Four different versions are available, either for raw gas burner applications or those requiring a partial air/gas premixture system and/or outlet temperatures up to 540°C. LV-4D AIRFLO® burners have a ductile iron body and #310 stainless steel mixing plates for applications with outlet temperatures up to 815°C. LV-5D AIRFLO® burners complement their ductile iron bodies with Hastelloy-X mixing plates for use in applications with up to 930°C outlet temperature requirements. LV-5B AIRFLO® burners have an aluminum bronze body casting with Hastelloy-X mixing plates for use with applications requiring up to 930°C outlet temperatures. For upstream process air temperature up to 565°C. Typical burner data Fuel: natural gas at 15°C with 10. 9 kWh/Nm3 HHV - sg = 0. 6 [1] Combustion air: 15°C - 21% O2 - 50% humidity - sg = 1. 0 [1] Stated pressures are indicative. Actual pressures are a function of air humidity, altitude, type of fuel and gas quality.

Refer to "Specifications of LV AIRFLO burners" for gas differential pressures to be used with alternative gas drillings. [. . . ] If correctly used within the performance limits as described on page 4-21. 4-7, both CO and NOx will remain far below the limits as determined in most standards.
