Boiler = Efficiency Parameters to be monitored for the calculation of boiler efficiency by direct method are: 1. Quantity of steam generated per hour (Q) in kg/hr. 2. Quantity of fuel used per hour (q) in kg/hr. 3. The working pressure (in kg/cm2(g)) and superheat temperature (oC), if …Learn More
The following formula is used to calculate the direct efficiency of a boiler. E = [ Q * (H-h) / (q*GCV) ] * 100. Where Q is the quantity of steam generated (kg/hr) H is the enthalpy of steam (Kcal/kg) h is the enthalpy of water (Kcal/kg) GCV is the gross calorific value of the fuel (kcal) q is the quantity of fuel (kg) Boiler Efficiency Definition. Boiler efficiency is defined as the percentage of input energy that a boiler …Learn More
Aug 26, 2011 · The efficiency on a lower heating value (LHV) basis increases slightly from 91.44% at 25% load to about 60% load and then tapers off. To determine burner duty, divide the boiler duty by the efficiency. Using a performance sheet obtained from a boiler supplier, one can get an idea of the fuel consumption at any load.Learn More
A typical condensing boiler has a thermal efficiency of 92-95%, in comparison to non-condensing boilers which typically have efficiencies of around 85%. These higher efficiencies are achieved by using the waste heat in the flue gases to preheat the water entering the boiler.Learn More

The efficiency formula has been used to calculate the boiler efficiency as follows (BEE, 2005; Patro, 2016): (3.63) η = ( output ) / ( input ) × 100 Direct efficiency calculation ( BEE, 2005 ; Patro, 2016)Learn More
A generally accepted "rule of thumb" is that about 5% of boiler input capacity can be recovered with a properly sized economizer. A higher percentage can be recovered with a Flue Gas Condenser, assuming there is enough cold water to condense all of the flue gas that is available. The calculations to determine the efficiency of condensing economizers are complex.Learn More
This answer assumes that you have enough instrumentation around the boiler to do all the calculations. Heat input: fuel flow rate and heating value (use LHV) Heat recovered: steam flow rate, pressure and temperature leaving the superheater, and enLearn More
