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

Determination of boiler efficiency Standards There are two main standards used for definition of boiler efficiency. Of those, the German DIN 1942 standard employs the lower heating value (LHV) of a fuel and is widely used in Europe. The American ASME standard is based on higher heating value (HHV).

### Direct and Indirect efficiency in boilers

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.

### Boiler Efficiency Calculation by Indirect Method

*As an example: A natural gas fired boiler's flue gas was measured on a wet basis to be 6% O 2 and 9% CO 2, the corrections would be: % O 2, dry basis = %, wet basis x F = 6% x 1.15 = 6.9%

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

### Boiler efficiency by loss Method - SlideShare

Sep 05, 2020 · 4) Deduct your existing boiler efficiency of 80% from the new boiler efficiency of 85% to calculate the efficiency improvement, in this case 20%. 5) Multiply your annual fuel bill by the efficiency improvement % to get your fuel saving figure: £800 x 0.05 = £40 saving per annum.

### Boiler Efficiency - an overview | ScienceDirect Topics

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
