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+/- 100 o F Heat Flux: /- 0.8 Btu/ft 2 sec Air Intake Velocity: /- 50 ft/min

Round Robin II Recommended Burner Configuration 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/ft 3 Fiberglass 2) 1 Layer Nextel Ceramic Paper/2 Layer 0.42 lb/ft 3 Fiberglass 3) 2 Layer 0.60 lb/ft 3 Curlon 4) 1 Layer TTI Felt/1 Layer 0.42 lb/ft 3 Fiberglass
