2.1 INTRODUCTION
Any material that can be burned to release thermal energy is called a fuel. Most familiar fuels consist primarily of hydrogen and carbon, called hydrocarbon fuels. Hydrocarbon fuels exist in all phases; some examples are coal, gasoline, and natural gas. Fuels are the materials which ignite in presence of oxygen and produce heat. The heat energy is then converted into various forms of energy. The different types of fuels like liquid, solid, and gaseous fuels are available for firing in boiler’s ...
