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
