•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/
