    I don't remember what it is for natural but lp gives you about 94,000 btus per gallon where oil you get about 145,000 btus per gallon.

    Those are btu content

    Numbers. Natural gas is 100,000 per therm, which is 100 cu.ft. I think I've seen #2 oil listed at 139,000/gl and LP at 93,000/gl.

    I think what he was asking is if there is an actual difference in the temp of the flame. I don't know the answer to that. Maybe Timmy or someone really smart on that stuff does.

    Gas Flame Temperature

    The Gas Engineers Handbook list a Natural gas Flame as having an average temperature of about 2800 degrees (F). I will have to look up oil flame temp. I will probably ask Alan Mercurio or George Lanthier I am sure they would know. Is there a particular reason you wanted to know?

    Just a little point of info, before mid efficiency and hi efficiency gas systems oil power burners were more efficient than gas atmospheric systems. Why? Simple the oil power burner used a motor therefore it needed less excess air about 20% versus the gas atmospheric needed 40 to 50%. Then again the Gas Power conversion burner installed to replace most oil burners would give about 78 to 80 % Combustion efficincy.

    Another difference is the ultimate CO2 of the two fuels natural gas is 11.7% oil is 15.2% this sometimes causes people to confuse the efficiency concept as gas is typically 8.5% to 9.5% oil can be up around 12 to 13%. they are actually at that point about the same efficiency.

    foggy memory serves, gas flame is around 1700-1800 degrees and oil is 2400-2500 degrees.
