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 Cm) Nextel paper target LabView Machine vision module

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

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 frames. Save data as.AVI movie format

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

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

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

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

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

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.
