# Boiler Efficiency Indirect Method

## vacuum water boiler t6

The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.

## water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

## Boiler Efficiency Indirect Method Related Information 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 ## Direct and Indirect efficiency in boilers

Direct and in There are two for calculation:- Direct Method Indirect Method Direct is quick method Following Data needs to be collected :- Excess Air supplied (EA) = O2% / (21-O2%) X 100 i Percentage heat loss due to dry flue gas ## (PDF) A CASE STUDY FOR CALCULATION OF BOILER

Boiler efficiency is determined by using indirect method and is calculate d as follows: (1) consist of a ## Boiler Efficiency Calculation by Indirect Method

Boiler Efficiency by Indirect Method = 100 - (L 1 + L 2 + L 3 + L 4 + L 5 + L 6 + L 7 + L 8) = 100 - (788 + 344 + 591 + 029 + 258 + 025 + 011 + 177) = 100 - 2223 = 7777% ## Boiler Efficiency Calculation by Indirect Method

· Indirect Method of Testing: ADVERTISEMENTS: In this method the efficiency can be obtained by substracting the heat loss fractions from 100 Boiler efficiency = 100 (L 1 + L 2 + L 3 + L 4 + L 6 + L 7 + L 8 ) Where L 1 = Loss due to dry flue gas
