Datasheet 205-4 Eclipse ThermJet Burners - Eclipse …

1 1. See Design Guide 205 for more information about typical fuel composition and properties All information is based on laboratory testing in neutral (0 " , 0 mbar) pressure chamber. Different chamber conditions may affectthe 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 timewithout being obliged to adjust earlier supplies accordingly.

2 Plumbing of air and gas will affect accuracy of orifice readings.
