The calorific value of a fuel represents the amount of energy released when it is burned. It is measured in megajoules per kilogram (MJ/kg) and is a key factor in determining the efficiency and suitability of fuels for different applications. Below is a comparison of the gross calorific values (GCV) of various types of coal and petroleum-based fuels.
| Fuel Type | Gross Calorific Value (GCV) (MJ/kg) |
|---|---|
| Anthracite Coal | 30-33 MJ/kg |
| Bituminous Coal | 24-30 MJ/kg |
| Lignite Coal | 10-20 MJ/kg |
| Crude Oil | 42-45 MJ/kg |
| Diesel | 44-46 MJ/kg |
| Gasoline | 43-45 MJ/kg |
✅ Coal Variability – The calorific value of coal depends on its carbon content and moisture levels. Anthracite coal has the highest energy content, while lignite coal has the lowest due to higher moisture content.
✅ Petroleum-Based Fuels – Diesel and gasoline offer higher energy efficiency than coal, making them ideal for transportation and industrial applications.
✅ Crude Oil as an Energy Source – Crude oil is highly energy-dense, making it a primary fuel source for refineries, power plants, and industrial processes.
Understanding calorific values helps industries select the right fuel for applications such as:
Power generation (coal-fired plants)
Transportation (diesel, gasoline)
By comparing calorific values, businesses and consumers can make energy-efficient and cost-effective fuel choices.
