1. See Design Guide 205 for more information about typical fuel composition and properties
• 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.

Emission 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
For estimates of other emissions, contact Eclipse.
