Example Direct Method Boiler Effeciency Calculation

Boiler Efficiency

Boiler efficiency may be indicated by Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses

Boiler Efficiency Calculation by Indirect Method | …

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. ADVERTISEMENTS: L 2 = Loss due to hydrogen in fuel. L 3 = Loss due to moisture in fuel. L 4 = Loss due to moisture in air.

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.
