### Direct and Indirect efficiency in boilers

The formula to calculate thermal efficiency is as follows: η= (Energy Output)/ (Energy Input) x 100 Total energy output is divided by energy input and multiplied by 100 to get percentage. This is the number that you see advertised by the boiler manufacturers.

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 (h2 – h1) / (q X GCV) X 100 Where Q = Qty of steam generated.

### Calculator: Boiler Efficiency | TLV - A Steam Specialist

According to boiler manufacturer ZBG, the thermal efficiency of hot water boiler is the ratio of the total output water heat and the boiler fuel heat. Through measure and calculate boiler heat losses, to acquire the thermal efficiency, this is negative equation way, that is, Qr=Q1+Q2+Q3+Q4+Q5+Q6 KJ/Kg.

### Boiler Efficiency: Introduction and Methods of Calculation

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.
