Calculation of Boiler Efficiency by Indirect Method: Boiler efficiency is estimated by the calculation of various losses in the boiler. The fuel analysis is normally made on the basis of proximate analysis and the proximate analysis can be converted to ultimate analysis.View More
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.View More
ASME PTC-4 – Indirect Method: Stack Loss Method This method approximates the stack losses of a boiler to estimate boiler efficiency. Parameters The parameters needed to calculate this method are given below. These data are calculated during source testing. 1. Stack temperature (T Stack) 2. Dry oxygen in flue gas (O 2,Dry,%) in percentView More

Direct Method. efficiency (η) = Heat Input/Heat …View More
There are two methods to determine boiler efficiency: direct method and indirect method. In this study, the efficiency of a fluidized bed boiler having a steam production capacity of 462000 kg/hView More
Boiler Efficiency by indirect method = 100 Œ (L1 + L2 + L3 + L4 + L5 + L6 + L7 + L8) 1.7.2 Measurements Required for Performance Assessment Testing The following parameters need to be measured, as applicable for the computation of boiler effi-View More
It is calculated by dividing the boiler output (in BTUs) by the boiler input (in BTUs) and multiplying by 100. The actual input and output of the boiler are determined though instrumentation and the data is used in calculations that result in the fuel-to-steam efficiency.View More
(3.65) Indirect method boiler efficiency = 100 – (HL1 + HL2 + HL3 + HL4 + HL5 + HL6 + HL7)View More
Thus, The Boiler Efficiency by indirect method = 100 "“ (L1+L2+L3+L4+L5+L6+L7+L8) Formula: Boiler Efficiency % = 100 "“ (L1+L2+L3+L4+L5+L6+L7+L8) Inorder to estimate the losses, Theoretical (stoichiom etric) air fuel ratio and excess air supplied are to be determined first.View More
Jan 14, 2015 · Unburnt losses in bottom ash (Carbon) Boiler Efficiency by indirect method = 100 - (L1 + L2 + L3 + L4 + L5 + L6 + L7 + L8) 6. This is also known as ‘input-output method’ due to the fact that it needs only the useful output (steam) and the heat input (i.e. fuel) for evaluating the efficiency.View More
There are basically two methods to calculate the efficiency of boiler, direct method and indirect method. Both the methods give different values as direct method does not consider any losses whereas indirect method gives the result by calculating all the losses.View More
This paper compares two methods for calculating boiler efficiency using test data obtained from the Boardman Coal Plant. The two test methods are ASME PTC 4’s Energy Balance Method …View More
The indirect efficiency of a boiler is determined by finding out the specific losses taking place in a boiler and then deducting the sum from 100%. This process involves getting out the dimensions of all the assessable losses taking place in a boiler by separate measurements.View More
