      Boiler Efficiency: Introduction and Methods of Calculation

      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 …

      BOILER EFFICIENCY GUIDE - Cleaver-Brooks

      key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

      The calculators use the specific heat capacity of water of 4186 J/kg/°C (Joules per kilogram per degree Celsius). The heat capacity is largely constant in the temperature range that the calculators work (34-210°F or 1-99°C). It is the way it is taught at school. For practical purposes, it should be precise enough.
