Nitrogen is considered as temperature reducing diluter. Almost 79% of air which is not oxygen is nitrogen. Rapid fuel oxidation results in large amount of heat. The process of combustion can be completely carried out only in the presence of adequate amount of oxygen. The heat of combustion is defined as the quantity of heat released in combustion of a fuel with oxygen.ĢH2 + O2 -> 2H2O + 28922 kcal/kg of hydrogen The heat of reaction is the quantity of heat exchanged between a system and its surroundings during a chemical reaction at a specified temperature. This energy is associated with the chemical bonds and intermolecular attractions. The actual reaction taking place due to combustion can be written down Fuel + O2 -> Product + Heatĭue to the combustion of fuel and air, heat energy is generated where the internal energy of the fuel species is the chemical energy. The combustion process is always exothermic and it liberates heat. The main products of the combustion process are carbon dioxide and water. It is a reaction between the fossil fuels such as coal or natural gas and oxygen.
