Boiler Efficiency: Introduction and Calculation Method ...

In practice two common methods are used to determine boiler efficiency ie direct and indirect methods of efficiency calculation. Direct efficiency. This method calculates the efficiency of the boiler by using the basic efficiency formula- = (Energy output) / (Input energy) X 100 To calculate the efficiency of the boiler by this method we divide the total energy output from the boiler by the total energy input given to the boiler

Methods for Calculating CHP Efficiency | Combined Heat and ...

Jul 16 2020 · Typical boiler efficiencies are 80 percent for natural gas-fired boilers 75 percent for biomass-fired boilers and 83 percent for coal-fired boilers. The calculation of effective electric efficiency is the CHP net electric output divided by the additional fuel the CHP system consumes over and above what would have been used by a boiler to produce the thermal output of the CHP system.
