2. Energy The various sources of energy can be listed as follows: 1.Fossil fuels 2.Nuclear fuels 3.Hydel energy 4.Sun(Solar energy) 5.Wind(Wind energy) 6.Tidal energy 7.Geothermal energy 8.Biomass and bio-fuels

3. Energy from fossil fuel

4. Classification of fuel Solid Liquid Gaseous Natural fuels Artificial fuels

5. Solid Natural Artificial  Wood  Peat  Lignite coal  Bituminous cool  Anthracite cool  Cock  Char coal  Briquettes coal  Pulverized coal

6. wood It is natural fuels and most commonly used as a domestic fuels. In some case it is used as industrial fuel for boiler furnace. The disadvantages of using wood as a fuel are its large moisture content and lower gross calorific value.

7. Coke is produced by reducing volatile matter of bituminous coal. It is hard,brittle and porous. it consists of carbon, mineral matter with 2%sulphur and small quantities of hydrogen, nitrogen and phosphorus. It is smokeless and clear fuel.

8. Liquid Natural Artificial  Petroleum  Gasoline  Diesel  Light diesel oil  Kerosene  Heavy fuel oil  Alcohol  Tar  Shale oil

9. Petrol It is lightest and most volatile fuel. It is mainly used for light petrol engine. Petrol comes out at 65 c to 220c by distillation of crude oil.

10. It is important by product obtained during manufacturing of coal gas. When it is redistilled, important fuel like benzene is produced.

11. Gaseous Natural Artificial  Natural gas  Liquefied Natural Gas (LNG)  Petroleum gas  Producer gas  Coal gas  Coal-over gas  Blast furnace gas  LPG  CNG  Sever gas  Water gas

12. Natural gas It consists of mainly methane and with small quantities of ethane, propane and hydrocarbon. It is found in upper part of petroleum field, under the earth ‘s surface. It is used for domestic and industrial heating.

13. LPG is colorless petroleum gas. It is natural derivative of both natural gas and crude oil. The main component gases of LPG are propane and butane or a combination of these two constituent.

14. Natural fuels  They occur in nature.  They are also known as primary fuels.

15. Artificial fuels  They are prepared by further processing of primary fuels.  They are also known as secondary fuels.
