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.

Boiler Efficiency Calculation by Indirect Method

The boiler efficiency also serves as an indication of the boiler performance and is obviously independent of the quality of the fuel. The above equation does not take into account the heat lost in the unburnt fuel. The loss has to be subtracted from the denominator for more accurate results. Indirect Method of Testing: In this method, the efficiency can be obtained by substracting the heat loss fractions from 100. Boiler

efficiency. Boiler efficiency, in the simplest terms, represents the difference between energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units will result in substantial fuel savings.
