Superheaters and reheaters are used where only dry steam is required in a process/machines such as Turbines. Any moisture content in a steam in such cases happens to degrade or corrode the machine thereby affecting its average operating life. So, superheater converts low-quality steam to high quality for end users.Superheaters can be used in a steam engine where absolute dry steam is needed to prevent wear and tear of engine parts.There are following types of superheaters: radiant superheater,...

The Boiler Replacement Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to drysteam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latentheat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase itsenthalpy.It is composed of superheater tubes or reheater tubes, tube/pipe support, elbow pipe,etc....

Tubular preheaters consist of straight tube bundles which pass through the outlet ducting of the boiler and open at each end outside of the ducting. Inside the ducting, the hot furnace gases pass around the preheater tubes, transferring heat from the exhaust gas to the air inside the preheater. Ambient air is forced by a fan through ducting at one end of the preheater tubes and at other end the heated air from inside of the tubes emerges into another set of ducting, which carries it to the...
