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 Enter the number 1-5 from the table above for the Current Fuel Gas: Enter the number 1-5 from the table above for the Proposed Fuel Gas: Background Data Enter current fuel gas volume per month FT3 Enter current fuel gas cost per 100 FT3 Enter current oxygen cost per 100 FT3 Determine Proposed Fuel Gas Cost Per 100 FT3 Enter proposed fuel gas price per lb, price per gallon OR price per 100 FT3 (enter only one value below) Proposed price per lb.: Proposed price per 100 FT3: Proposed price per gal Proposed price per 100 FT3: Proposed price per FT3: Proposed price per 100 FT3: Current Fuel Gas Volume Per Month Proposed Fuel Gas Volume Per Month FT3 / Month FT3 / Month Current Fuel Gas Cost Per Month Proposed Fuel Gas Cost Per Month Per Month Per Month Pre-Heat Oxygen Volume Per Month Proposed Pre-Heat Oxygen Volume Per Month FT3 / Month FT3 / Month Pre-Heat Oxygen Cost Per Month Pre-Heat Oxygen Cost Per Month Per Month Per Month Current Proposed Fuel Gas Fuel Gas PH Oxygen PH Oxygen Total Total Monthly Savings: Annual Savings: Cost will be automatically calculated using values from the gas table at the top of the form as well as entered values. Remember that oxygen costs for actual cutting are not considered in the calculations.
