5
Lower Calorific Value
• It is defined as
• “the net heat produced ,when a unit quantity of the fuel is
completely burnt
...
Calculation of Net calorific value
Net calorific value=gross calorific value-latent heat of water vapours
Ncv=Gcv-weight o...

Theoretical Calculation Of Calorific Value
Dulong’SFormula :
• If both hydrogen and oxygen are present, it may be
assumed ...

Let us discuss few multiple choice questions
• Que1.Agood fuel possess:
a. Net calorific value
b. Lower calorific value
