No. 6 fuel oil has a combustion value of 151,300 - 155,900 Btu/US gallon.
approx. 140,000
btu per pound * pounds per gallon OK, it sounds as if you know the value of fuel in oil btu per pound.Now find out how much a gallon of fuel oil weighs and multiply the btu value x that weight in pounds and that is the value per gallon. Or simply, diesel fuel is #2 fuel oil which contains 140,000 btu per gallon.
#2 fuel oil = 140,000 btu/gallon. Psi does not matter.
About 115K BTU per gallon.
#2 fuel oil = 140,000 btu per gallon/10 =14000 btu X 2 =28000 btu
Natural gas= 1000 btu per cubic ft, propane =2500 btu per cubic ft and #2 fuel oil = 140,000 btu per gallon. Check the availability & prices in your area and you can figure your answer.
