Gross and net calorific value of a fuel will be the same__________________?
Correct answer: C. If its hydrogen/hydrogen compound content is zero
- A. If its ash content is zero
- B. If its carbon content is very low
- C. If its hydrogen/hydrogen compound content is zero
- D. Under no circumstances
Explanation
Gross calorific value includes the heat recovered when water formed from hydrogen condenses, whereas net calorific value excludes this latent heat. They are therefore equal only when the fuel contains no hydrogen or hydrogen-containing compounds.
