Steam Generator, well known as boiler is an equipment designed to boil liquid to steam. Steam is produced by means of transferring of heat to water and combustion, this is provided by an enclosed vessel acknowledged as a boiler. The usable steam or hot water under pressure is intended at transferring the heat to a process. Heat is transferred to a process water used as a reduced medium. Volume of water increases about 1,600 times when it is heated, the force produced is just about equivalent as that of an explosive of gunpowder. At this point the boiler becomes really dangerous machinery that has to be used with carefulness. Evaporation arise about when a liquid is heated up to a vaporous phase.
