Calculate industrial boiler efficiency Thailand

When buying boilers, many customers are concerned about boiler efficiency and boiler price. So how do we calculate the boiler efficiency?

In actual practice, two methods are commonly used to find out boiler efficiency, namely direct method and indirect method of efficiency calculation.

Direct efficiency
This method calculates boiler efficiency by using the basic efficiency formula-
η=(Energy output)/(Energy input) X 100
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 by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%. This method involves finding out the magnitudes of all the measurable losses taking place in a boiler by separate measurements. All these losses are added and subtracted from 100% to find out the final efficiency. Blow down valve is kept closed during the procedure. This method should be implemented as per the norms provided in BS845 standards. The losses calculated include stack losses, radiation losses, blowdown losses etc.

Of course, the specific values need to be calculated based on detailed information. More than information calculate industrial boiler efficiency Thailand, please consult ZBG online customer service.
