Sep 23, 2009 · Boiler Efficiency calculations Efficiency is a very important criterion in Boiler selection and Design. Efficiency figure depends upon the type of boiler as well as on the type of fuel and it's constituents. For example, efficiency of a Bagasse fired boiler is about 70% where as that of oil fired boilers is about 85 %.

Read MoreBoiler Efficiency - Boiler efficiency is the percentage of the total absorption heating value of outlet steam in the total supply heating value. Cycle Efficiency - Cycle Efficiency is a ratio that measures the effectiveness and productivity of the production process by comparing the value added time with the total production time. Turbine Efficiency - Turbine Efficiency is the ratio of actual

Read MoreDec 03, 2020 · Boiler efficiency(n)=[{Qx(hg - hf)}÷q×GCV]×100 . Where, hg = enthalpy of saturated steam in kcal/kg of steam. hf = enthalpy of feed water in kcal/kg of water. The fuel calorific value may be gross or net or accordingly, the efficiency reported is referred to as efficiency on GCV or NCV basis. Let's take a example, Example:-

Read MoreCalculating boiler efficiency There are two different means of calculating the boiler efficiency: The direct method and the indirect method. 12 Direct method In the direct method, the boiler efficiency is directly defined by the exploitable heat output from the boiler and by the fuel power of the boiler: φoutput η= (14) φinput where φ
