Superheaters must be installed in a radiant zone. In high-pressure boilers when the temperature difference in saturated and superheated steam is around 100 oC. Radiant superheaters are the type of superheaters that are installed in a radiation zone just after the furnace. Designing Parameters of Industrial Superheatersĭepending upon the steam temperature requirement, Superheaters are divided into two parts: Radiant Superheaters Shell type superheaters design generally used to superheat the steam electrically using special heating elements stacked in a shell and the steam flows over the heating elements. In a coil type designs steam is inside the coil and flue gases are outside the coil. Thermodyne manufactures both coil type and shell type superheaters depending upon the type of boiler and boiler capacity.Ĭoil type superheaters design generally consists of 180 o coils welded through the headers on both the sides. Our superheaters are manufactured according to the IBR Regulations. In other cases, separately fired superheater may be required because gas turbine produced gases are relatively cool.įunction of superheater in boiler Boiler Superheater’s Manufacturing 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.Superheaters can be used in a steam engine where absolute dry steam is needed to prevent wear and tear of engine parts.
Sometimes, superheater is also needed when we need to transport steam to far off places as there are some temperature losses during its transportation.So, superheater converts low-quality steam to high quality for end users. Any moisture content in a steam in such cases happens to degrade or corrode the machine thereby affecting its average operating life. Superheaters are used where only dry steam is required in a process/machines such as Turbines.Use of Superheaters in Industrial Boilers Increases the temperature of saturated steam by removing entrained water particles from turbines steam.Reduction of condensation loss in the boiler steam pipes.
