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.
