Condensation of Water Vapour in Combustion

Water vapour is a byproduct of combustion, and its presence in the products of combustion affects the calorific value of the fuel. When water vapour is present in the products of combustion and is condensed to the initial temperature of the fuel, the higher calorific value of the fuel is achieved.

Explanation:

- When water vapour is condensed to the initial temperature of the fuel, the latent heat of vaporization is released, which increases the total heat released during combustion.
- This additional heat released due to the condensation of water vapour contributes to the higher calorific value of the fuel.
- The energy content of the fuel is calculated based on the total heat released during combustion, which includes the heat released from the condensation of water vapour.
- Therefore, when water vapour is condensed to the initial temperature of the fuel, the higher calorific value of the fuel is obtained.

In conclusion, the higher calorific value of fuel occurs when water vapour present in the products of combustion is condensed to the initial temperature of the fuel. This condensation process releases additional heat, contributing to the overall energy content of the fuel.
