- Calculation Of Boiler Efficiency

In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where, Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency. The indirect efficiency of a boiler is calculated …

Learn MoreThe efficiency of a firetube boiler is not a mysterious calculation. High efficiency is the result of tangible design considerations incorporated into the boiler. Reviewing some basic design differences from one boiler to another can provide you with valuable insight on expected efficiency performance.

Learn MoreBoiler Efficiency. Boiler efficiency includes the calculation of sensible heat losses (in boiler flue gases and ash), which are dependent on coal composition, excess air levels and temperatures at boiler inlet and airheater outlet. From: The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013.

Learn MoreJul 04, 2020 · Then calculate the Boiler efficiency. Consider ambient air, flue gas out let temperature are 30 and 150 °C respectively, humidity in ambient air is 0.02 kg/kg of dry air. From the given data, boiler efficiency can be calculated from indirect method.

Learn Moremajor factor that could significantly affect the boiler efficiency is the basic boiler design. A particular boiler design can be produced to be more efficient with some creativity in calculating the efficiency, as there is room for interpretation for its calculation. (Fig. 1) shows the fire tube boiler gas flow. The following are the key

Learn MoreIndirect 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.
