Steam Generator, well known as boiler is a tool designed to vaporise liquid to vapour. Hot water or steam is produced by means of transfer of heat to water and combustion, this is provided by an enclosed vessel acknowledged as a boiler. The functional steam or hot water under pressure is used for transferring the heat to a process. Heat is transferred to a process using water as a cheap medium. The volume of water upsurges about 1,600 times when it is boiled, the force produced is practically the similar as that of an explosive of gunpowder. At this point the boiler becomes really hazardous equipment that has to be used with caution. Evaporation come about when a liquid is heated up to a vaporous phase.
