Fuel Efficiency
Fuel Efficiency
Efficiency of a fuel is measured by its calorific value. Calorific value is the amount of heat produced by the complete burning of 1 kg of fuel. Hence, calorific value of fuel is expressed in kilo joule per kg (k J/kg). A fuel with higher calorific value is considered as an efficient fuel. When a fuel is burnt, some of the energy produced is given off as waste heat, which cannot be used for cooking or other purposes. Till the date no furl device is known to exhibit 100% efficiency.
Following are the some of the important characteristics of ideal fuel:-
1. It should have high calorific value.
2. It should have a moderate rate of combustion and should release heat in a controlled manner.
3. It should be fairly cheap and easily available.
4. It should be safe to handle, store, and transport.
5. It should not cause pollution on burning.
