Table A.3 Gas Gun Press. Drop vs. Burner Heat Input
• Pressure drops for natural gas, 1,000 Btu/SCF gross, 0.6 specific gravity.
• Pressure drop should be taken as differential between the chamber and gas gun
pressure tap.
Gas Gun Pressure Drop ("w.c.)*
Note:
Fuel pressure drop curves should be used as a guide for setting up
burner. It is recommended to use a direct fuel flow measurement
(orifice plate or flow meter) for calculating actual fuel flows.
