NOTES:
1. Capacities based on Natural Gas with HHV of 1034 Btu/ft
3
, (Standard), and LHV of 10.21 kWh/nm
3
(Metric)
0.59 S.G., and a stoichiometric ratio of 9.74:1 with burner firing into chamber under no pressure at 10% excess
air.
2. Air and fuel flows based on STP operating conditions at sea level and industry standard air and gas piping
practices.
3. Gas inlet pressure given for reference only and should not be used for measuring fuel flow to the burner.
4. Flame lengths measured from end of the combustion tile.
5. Burner is suitable for use on gaseous fuels other than Natural Gas and with combustion air other than ambient
temperature, consult Hauck.
