Presentation Transcript
slide1
Round Robin II Calibration/Test Results
  • Impact of Burner Tab and Intake Duct on Calibration/Test Results
  • Variations in Burner Air Turbulators Discovered
slide2
Round Robin II Calibration Requirements
  • Air Intake Velocity: 2150 +/- 50 ft/min
  • Thermocouple Rake Temperatures: 1850+/- 100oF
  • Heat Flux: 16.0 +/- 0.8 Btu/ft2 sec
slide3
Round Robin II Recommended Burner Configuration
  • Igniters @ 10:00 Position
  • 1 Tab in Top Left Position
  • Static Disc In Draft Tube
  • 3.75-Inch Distance from Nozzle Tip to Turbulator
slide4
Round Robin II Material Combinations:

1) 2 Layer 0.60 lb/ft3 Fiberglass

2) 1 Layer Nextel Ceramic Paper/2 Layer 0.42 lb/ft3 Fiberglass

3) 2 Layer 0.60 lb/ft3 Curlon

4) 1 Layer TTI Felt/1 Layer 0.42 lb/ft3 Fiberglass

4 Burner Configurations:

No Tab/With Duct (NTWD)

No Tab/No Duct (NTND)

With Tab/With Duct (WTWD)

With Tab/No Duct (WTND)

slide32
Tab/Intake Duct Test Conclusions

Burner Calibration Influenced More From Tab Than Duct

Test Results Influenced More From Burner Set-up Than Calibration

No Tab = Temp Calibration = Quicker Failure Time
