Study Notes
Chemical Fuels
- The main constituent of chemical fuel for domestic and industrial purposes is Hydrocarbons.
Classification of Fuels
- Fuels are classified into two categories: Natural Fuels and Artificial Fuels, based on whether they occur in nature or are prepared.
Calorific Values
- The formula used for calculating both Gross and Net calorific values is: Q = (m × ΔHc) / M, where Q is the calorific value, m is the mass of the fuel, ΔHc is the heat of combustion, and M is the molecular weight of the fuel.
Fuel Properties
- The measure of a fuel's resistance to knocking in internal combustion engines is Octane Rating.
Petroleum Refining
- The refining process of crude petroleum to produce liquid fuel is Cracking, which involves the breakdown of large molecules into smaller ones.
