  • Boiler Efficiency Calculation by Indirect Method | Thermodynamics

    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.Get Price
