  • Calculating Boiler Efficiency - Forbes Marshall

    Indirect Efficiency. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%. This method involves finding out the magnitudes of all the measurable losses taking place in a boiler by separate measurements. All these losses are added and subtracted from 100% to find out the final efficiency.

  • How to calculate boiler efficiency by Direct Method

    Nov 24, 2016 · There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) Boiler Efficiency by Indirect Method: Where the efficiency is the difference between the losses and the energy input.

    • What is the Difference Between Direct and Indirect Fired

      Indirect fired heaters are just like your home oil or gas burning furnace with a chimney. With propane or natural gas heating units, the flame is contained in a burn chamber which heats a “heat exchanger”. The cooler air passes over and around the heat exchanger, thus heating the air.
