3Quicker 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
4Test set up
- I/R Camera
- Frame
- Burner
- Paper holder
5Test 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
6Post recording processing
- Intel P2 400Mhz or higher
- LabView and Capture software required
- Evaluation is internet capable
7Numerical 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

9Select file to interpret
10Pre recording alignment
- Turn on cone marker
- Align to cone photo
11Select video and process
- Select from file
- Annotate photo
- Start
- Save Data
- Save photo
12photo of burner value can be saved and sent in
for review
- Changes can be studied
- Burners can be matched
13Pre and Post image adjustments
- Different way to look at the flame
- Temperature range adjustments
14Determine if there is really a difference in lab
burners
- Measure with a micrometer
- cut with a AX
- numerical value for each burner each cal
15Future 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.
16Mapped 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
