2019-11-27 · The steam generated by a boiler is generally wet or at most dry saturated. Super heater is used to increase the temperature of steam above its saturation point, since superheating result in the increase in efficiency and economy of the steam plant.
A boiler is an enclosed vessel that provides a means for combustion and transfers heat to water until it becomes hot water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process.
When water at atmospheric pressure is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gun powder. This causes the boiler to be an equipment that must be treated with utmost care. The boiler system comprises of: a feed water system, steam system and fuel system.
