Question

3. Why are gaseous fuels considered better than liquid
or solid fuels.
​

Answer 1

Answer:

The calorific value of gaseous fuels is more than solid and liquid fuels. When a gaseous fuel burns, it gives off a great deal of energy. Unlike other solid and liquid fuels it does not leaves any ash. Gaseous fuels produce very little air pollution.

Answer 2

Answer:

Explanation:

Calorific value is defined as the amount of heat energy produced on complete combustion of 1 kilogram of fuel. It is expressed in a unit called kilojoule per kg. The higher the calorific value of a fuel, the more is its efficiency.  

The calorific value of gaseous fuels is more than solid and liquid fuels. When a gaseous fuel burns, it gives off a great deal of energy. Unlike other solid and liquid fuels it does not leaves any ash.  

Gaseous fuels produce very little air pollution. Due to the above reasons, gaseous fuel is always better than solid and liquid fuels.
