How to Calculate Boiler Efficiency By Direct Method - YouTube. 29 Apr 2020 Boiler efficiency = Heat output/ Heat input Or Boiler efficiency = [Q x (hg- hf)/ q x GCV] x 100 Where, Q = quantity of steam generated per hour (Kg/. Boiler Efficiency Calculation !Simple and easy method. - YouTube.

Read MoreIn 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.

Read More7/10/2020 · Using direct method we can calculate the boiler efficiency using below formula. In this method we do not consider various losses of energy in boiler process. Where, m = steam generation (kg/h), H g = Enthalpy of steam (kcal/kg), H l = Enthalpy of feed water (kcal/kg), W = Coal feed rate (kg/h), GCV = Gross calorific value (kcal/kg)

Read MoreDirect 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.
