A fuel is considered good or desirable when it has a low ignition temperature and generates a significant amount of heat. It reflects it high in its calorific value. Ideal fuels should be easy to store, leaving behind ash after they are burned and quickly combust. They are inexpensive , readily available and do not emit any harmful smell. While burning can be easily carried and can be regulated.
A good fuel should have the following characteristics.
