      Boiler Efficiency - an overview | ScienceDirect Topics

      The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

      Calculating Boiler Efficiency - Forbes Marshall

      The combustion efficiency of a boiler is the indication of burner’s ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.

          Boiler Efficiency Ratings. Each boiler unit comes with an AFUE (annual fuel utilization efficiency) rating. Higher ratings mean they transfer energy into heat more efficiently, lowering your heating bills and your environmental impact. An AFUE of 90 means 90% of the energy supplied to the boiler transfers into actual heat in the home. High efficiency: AFUE of 90 or higher.
