• APPENDIX 1 MEASURING BOILER EFFICIENCY

    App 1-7 HHV is the higher heating value, hg is the enthalpy in Btu/lb of water vapour at 1 psi and the flue gas temperature (FGT) in °F, and hf is the enthalpy of water at the combustion air temperature (CAT) in °F. hg can be determined from steam tables or from the equation hg, Btu/lb = 1055 + (0.467 x FGT). hf can also be determined from steam tables, or from the simple relationshipLearn More

  • Pellet fuel - Wikipedia

    The energy content of wood pellets is approximately 4.7 – 5.2 MWh/tonne (~7450 BTU/lb), 14.4-20.3 MJ/kg.. High-efficiency wood pellet stoves and boilers have been developed in recent years, typically offering combustion efficiencies of over 85%. The newest generation of wood pellet boilers can work in condensing mode and therefore achieve 12% higher efficiency values.Learn More

  • Natural Gas Vs Fuel Oil Vs Propane: The Furnace/Boiler

    Apr 05, 2018 · That means, there are 1 million Btu in every 11 gallons of propane. As there are 150,000 Btu per gallon of fuel oil, there are 1 million Btu in every 6.66 gallons of fuel oil. So, in order for fuel oil to be cheaper than natural gas, the price of a gallon of fuel oil must be 33.33 percent of the price of one million Btu of natural gas.Learn More

    residual No. 6 oil with No. 2 heating fuel in a 50/50 mix, and has a heating value of approximately 146,000 Btu/gal. No. 4 oil is normally used in industrial and commercial boilers, as well as in marine vessels. Because No. 4 distillate is made using residual and distillate fuels, it possesses some qualities of both fuel types.Learn More
