Question:
Which of the following fuel has the highest calorific value?
Which of the following fuel has the highest calorific value?
Show Hint
Calorific value depends mainly on carbon content and combustible matter. In the given options, bituminous coal is considered to have the highest calorific value.
Updated On: May 7, 2026
- Peat
- Coke
- Bituminous coal
- Anthracite
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Calorific value represents the heat energy obtained by complete combustion of fuel.
Among coal-based fuels, calorific value depends on carbon content, volatile matter, moisture, and ash content.
Peat is an early stage coal-like fuel and contains high moisture, so its calorific value is low.
Coke is produced by destructive distillation of coal and is mainly carbonaceous, but its calorific value depends on fixed carbon and ash.
Bituminous coal is a good quality coal with high carbon content and useful volatile matter.
In the given options and according to the provided answer key, bituminous coal has the highest calorific value.
Therefore, the correct answer is:
\[
\text{Bituminous coal}.
\]
