    Efficiency Terms used to qualify efficiency in the context of a boiler include simply efficiency, boiler efficiency, thermal efficiency, combustion efficiency and fuel-to-steam efficiency. The terms, Efficiency and Boiler Efficiency, by themselves are, essentially, meaningless since they must be qualified in order to understand their significance.

    Non-condensing boilers typically have efficiency ratings that range from 80% to 88%, while those of condensing boilers are usually above 88%. To qualify for an ENERGY STAR® certification from the Environmental Protection Agency and U.S. Department of Energy, oil-fired boilers must exceed 87% AFUE and gas-fired boilers must exceed 90% AFUE.

  • Steam Boiler: What Is It? How Does It Work? Types Of

    Oil steam boilers operate on the same principles as gas boilers; oil is ignited in the combustion chamber instead of gas. The burning oil heats the exchanger that heats the water. Oil steam boilers can reach an efficiency of over 90%.

  • 1.4 Natural Gas Combustion

    Depending on a number of factors including coal properties, boiler efficiency typically ranges between 87% and 89% while firing coal. The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal
