INTRODUCTION

Combustion is a process of rapid exothermic oxidation, in which a fuel burns in the presence of oxygen with the evolution of heat and light.

Aim of combustion is to get the maximum amount of heat from a combustible substance in the shortest time. Most of the combustible substances are enriched with carbon and hydrogen. During combustion they undergo thermal decomposition to give simpler products, which are oxidised to CO2, H2O, etc.,

C + O2 → C O2 ; Exothermic

H2 + 1/2 O2 → H2O ; Exothermic.

Since the above reactions are exothermic, large quantity of heat is given out.
