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

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/
