Advanced Performance Inject-Aire
Two designs - One solution
The Advanced Performance Inject-Aire Low NOx Burner (API) produces an exceptionally stable flame at all firing rates. Capable of firing natural gas, light oil, heavy oil, digester gas, ethanol, and more, the API-AF offers a wide range of fuel burning capability. Our engineers specifically designed this burner speed up installation, reduce space requirements, and facilitate maintenance when needed. The API burner incorporates VFD for control of FD fan speed, resulting in significant electrical reductions, regardless of the type of fuel burned.
Capacity – 4 MMBTUH – 120 MMBTUH
Fuel – Natural gas, #2-#6 Oil, specialty fuels
NOx Levels – 30 PPM for Natural Gas
Turndown – 10:1 for Natural Gas; 8:1 for #2 oil
Recommended Boiler Type- Firetube, Flextube, Firebox, Cast Iron Sectional, Watertube
Recommended Use – Commercial or Industrial

Controls
The AP burner comes completely integrated with Preferred's BurnerMate Universal flame safeguard and combustion controller. It features:
-Variable speed drive control for the FD fan and oil pump motor.
-Dual scanner inputs for fault-proof redundant flame scanning.
-Integrated first out annunciator for easy trouble-shooting.
-Parallel positioning combustion control with oxygen trim using the Preferred ZP line of in-situ oxygen analyzers.
-Recommended Boiler Type- Firetube, Flextube, Firebox, Cast Iron Sectional, Watertube
-Recommended Uses (commercial or industrial) – Commercial or Industrial
Fuel Variety: No 2 through No 6 Fuel Oil, and/or natural gas.
Advanced Design: our engineers specifically designed this burner to eliminate field errors, reduce space requirements, and facilitate maintenance when needed.
Model Options: two models are available: RF is designed for larger capacities and allows for the fan to be placed remotely; the AF is designed for smaller applications and ease of maintenance.
