ASME Standard Steam Superheaters in Industrial Boilers with high quality

Description of Boiler Superheater

• The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.
• It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.

Benefits of Superheaters in Boilers

• Increase in efficiency of the steam power plant
• Minimized erosion of turbine blade
• Less steam consumption
• Reduction of condensation loss in the boiler steam pipes
• Increases the temperature of saturated steam by removing entrained water particles from turbines steam

Use of Superheaters in Industrial Boilers

• Superheaters 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.
• Sometimes, superheater is also needed when we need to transport steam to far off places as there are some temperature losses during its transportation.
• Superheaters can be used in a steam engine where absolute dry steam is needed to prevent wear and tear of engine parts.
• In case of water tube boilers, hot gases will provide the required temperature to produce superheated steam and superheater may be an additional part of the furnace area. In other cases, separately fired superheater may be required because gas turbine produced gases are relatively cool.
