Maximum Combustion Air Temperature
300°F (149°C). For higher temperatures use TJPCA (Datasheet 206).
Flame Detection
Flame rods can be used with all combustors, natural gas, and
operating temperatures up to 2,200°F (1,204°C).
UV scanners can be used with all combustors, any fuel listed below,
and up to the maximum operating temperature.
Fuel

• All information is based on laboratory testing in neutral (0 "w.c., 0 mbar) pressure chamber. Different chamber conditions may affect
the data.
• All information is based on standard combustor design. Changes in combustor will alter performance and pressures.
• All inputs based upon gross calorific values and standard conditions; 1 atmosphere, 70°F (21°C).
• Eclipse reserves the right to change the construction and/or configuration of our products at any time
without being obliged to adjust earlier supplies accordingly.
• Plumbing of air and gas will affect accuracy of orifice readings. All information is based on
generally acceptable air and gas piping practices.

Emissions correction factor for medium velocity combustor is
1.20. Emissions data based on, on-ratio control firing at 15%
excess air corrected to 3% O2.
Emissions from the burner are influenced by:
• Fuel type
• Combustion air temperature
• Firing rate
• Chamber conditions
• Percent of excess air
