  1. FUEL

  2. DEFFINATION • It is a comastable substance having carbon as the masor constituent which is the proper burning profiles a large quantity of heat. That can be used economically for domestic and industrial purposes. • Example-coal, wood, .P.G gas

  3. CLASSIFICATION OF FUEL • Depending on origine fuels are two types. • primary fuel or Natural fuel • secondary fuel or Derived fuel.

  4. PRIMARY FUEL OR NATURAL FUEL • These are the fuels obtend from the nature • Example-Wood, Coal, Natural gas etc.. • SECONDARY FUEL OR DERIVED FUEL • These are the fuels obtend by the purification of natural fuels • Example-Petrol, Diesel, L.P.G gas, Coke etc.. • Depending upon the fiscal states, fuels are three types. • Solid fuel • Liquid fuel • Gaseous fuel

  5. PRIMARY FUEL OR NATURAL FUEL • These are the fuels obtend from the nature • Example-Wood, Coal, Natural gas etc.. • SECONDARY FUEL OR DERIVED FUEL • These are the fuels obtend by the purification of natural fuels • Example-Petrol, Diesel, L.P.G gas, Coke etc.. • Depending upon the fiscal states, fuels are three types. • Solid fuel • Liquid fuel • Gaseous fuel

  6. LOWER CALORIFIC VALUE OR NET CALORIFIC VALUE • It is the amount of heat liberated during the combustion of the fuel only • HIGHER CALORIFIC VALUE OR GROSS VALORIFIC VALUE • It is the sum of the heat liberated during the combustion and pulling of the combustion products to room temp. • Unit of calorific value. • Cal/gm---------------- kcal/kg • Cal/cc----------------- kcla/m3

  7. CHARATARASTICS OF A GOOD FUEL • A fuel should have high carbon content. • A high calorific value. • Low volatice matter. • Low moisture contained. • It should be of low cust. • It should be easily transformable • It should produce ash
