API-AF Burner

  •  
  • Introduction
  •  

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.

  • Burner Control & Monitoring
  •  
Parallel/full metering firing rate control: any Preferred controller, including our new BurnerMate Light.Oxygen sensor: Model “ZP” In-Situ sensor, reliable zirconia oxide detector.Monitoring: SCADA/Flex remote monitoring and control system.Instruments: Standard and optional equipment available.

  • Additional Options
  •  

Draft control, drum level control, low fire fuel changeover, dual/redundant flame scanning, smoke opacity monitoring and alarm, atomizer post purge capability, flue gas temperature indication alarm, emergency boiler shutdown. Note: NOx performance depends on furnace geometry and heat release rate. Lower NOx emissions are attainable by introducing FGR.
