In actual practice, two methods are commonly used to find out boiler efficiency, namely direct method and indirect method of efficiency calculation. Direct efficiency. This method calculates boiler efficiency by using the basic efficiency formula-η=(Energy output)/(Energy input) X 100.
Read MoreNov 24, 2016 · 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. 12 important things should know during boiler walk down check up
Read MoreIndirect Method. Direct method: Direct method is quick method for boiler efficiency calculation, In this method, Percentage of total heat output vs heat input is calculated to establish boiler performance. Boiler Efficiency = Heat output / Heat Input X 100. Or Boiler Efficiency = Q X (h3 – h1) / (q X GCV) X 100. Where Q = Qty of steam generated.
Read MoreAug 29, 2017 · The calculation of boiler’s fuel efficiency boiler should consider the consumption amount of fuel used, so it is very appropriate to be used as a point of boiler economic analysis. Direct Method. There are two popular methods for calculating the fuel efficiency of the boiler; the direct method and the indirect one.
Read MoreBoiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
Read MoreBoiler Efficiency Calculation by Direct Method. How do you calculate boiler efficiency by direct testing method? Direct Method Testing or Input Output Method. The direct method testing is also sometimes referred to as input-output method. This method estimates the boiler efficiency using the heat added to the steam and the gross heat in the fuel.
Read MoreUnderstanding Indirect Boiler Efficiency. Indirect Efficiency Calculation & BS845. The method most standards (including IS8753, BS845 etc.) follow is the indirect efficiency calculation method. In this method, each loss is individually calculated, and the sum of these losses is then subtracted from 100 to give efficiency %.
Read MoreIn real practice, two techniques are usually used to find out boiler performance, namely direct method and indirect method of efficiency calculation. Direct efficiency This is also recognized as the input-output method because it requires only the valuable output like steam and the heat input for estimating the boiler efficiency.

The Indirect Method Testing/Loss Method L1. Loss due to dry flue gas (sensible heat) L2. Loss due to hydrogen in fuel (H2) L3. Loss due to moisture in fuel (H2O) L4.
Read MoreThe following article will guide you about how to calculate boiler efficiency by indirect method. Definition of Boiler Efficiency: The boiler efficiency is defined as the ratio of heat actually used for producing steam in a certain period to the heat supplied in the furnace during the same period.
Read MoreBasically Boiler efficiency can be tested by the following methods: 1) The Direct Method:Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) The Indirect Method:Where the efficiency is the difference between the losses and the energy input. 1.6 The Direct Method Testing 1.6.1
Read MoreApr 15, 2020 · The values of boiler energy efficiency at partial load obtained using boiler loss calculation, and indirect method (90.98%, 91.91%, 91.84%) and direct calculation using the developed thermodynamic model (91.47%, 91.64%, 91.55%) are presented in Table 15. In both cases, the highest efficiency value was obtained for the middle boiler load (Load
