  1. Oil Burner optical flame analysis The International Aircraft Materials Fire Test Working Group March 5-6 2003 Atlantic City NJ.

  2. International Aero IncFire protection laboratorySupports these Regulatory Agencies and Industry Groups

  3. Quicker and improved burner calibration • Optical machine vision flame analysis • 1.2 μm IR camera • BT Rig adapter frame • 24” x 24” (60.96 Cm X 60.96 Cm) Nextel paper target • LabView Machine vision module

  4. Test set up • I/R Camera • Frame • Burner • Paper & holder

  5. Test set up After burner calibration IAW Test method Camera is aligned to center of cone / fuel nozzle Install Nextel paper and re align burner to impinge on the paper at the same location as the insulation on burn through device. Pre heat burner and rotate on to Nextel paper start video recording for 200-300 frames. Save data as .AVI movie format

  6. Post recording processing • Intel P2 400Mhz or higher • LabView and Capture software required • Evaluation is internet capable

  7. Numerical averaging • Video shot through a #10 welding glass to attenuate the iridescence from the Nextel paper • Short wave length IR camera • 30 Frames per second (30fps) • Each frame is 300 X 300 pixels • Each pixel has a value of 0-256

  8. Evaluation Instrument • Virtual device

  9. Select file to interpret • Pull down menu

  10. Pre recording alignment • Turn on cone marker • Align to cone photo

  11. Select video and process • Select from file • Annotate photo • Start • Save Data • Save photo

  12. photo of burner value can be saved and sent in for review • Changes can be studied • Burners can be matched

  13. Pre and Post image adjustments • Different way to look at the flame • Temperature range adjustments

  14. Determine if there is really a difference in lab burners • Measure with a micrometer • cut with a AX • numerical value for each burner each cal

  15. Future work • Calibrate the IR image to more accurate temperature measurements • Validate the test method • develop a burner value using the method and collect data from the BT labs.

  16. Mapped demo • 600 hours to develop refine • Can be run as a stand alone or over the internet • Easy and cheap setup ($300-500 • Repeatable • Requires licensed software
