  The Harris Products Group Fuel Gas Cost Analysis
The Harris Products Group Fuel Gas Cost Calculator uses known or calculated BTU values of the different fuel gases to estimate cost. It will calculate costs of fuel and oxygen required to burn the given amount of fuel gas at average flame intensity. It calculates only for preheat gases when cutting and the assumption is made that the amount of oxygen used for actual cutting will remain the same for all gases. BTUs and Oxy-Fuel ratios are calculated averages.
             
        BTU / FT3 Avg. O2 to Fuel Ratio Lbs. / Gallon FT3 / Lb.    
1 Acetylene 1470 1.5:1 - 14.6
2 Butane 3374 4.0:1 4.7 6.4
3 Propylene 2371 3.0:1 4.35 9.03
4 Propane 2563 4.0:1 4.2 8.66
5 Natural Gas 1000 2.0:1 4.28 23.6
