ASME Steel Heat Exchanger Tube Superheater And Reheater For Steam Boiler

Product Specification

High Quality Steel Heat Exchanger Tube Superheater Reheater For Steam Boiler

The superheater is one component in the boiler that serves to further heat the steam to produce steam that meets the requirements for turning turbines.

The superheater is a collection of boiler pipes located in the flow of hot gas from combustion. The heat from this gas is transferred to Saturated Steam in the superheater pipe, so it turns into superheated steam.

Boiler Superheater’s Manufacturing

Our superheaters are manufactured according to the ASME Regulations. HDB manufactures both coil type and shell type superheaters depending upon the type of boiler and boiler capacity.

Coil type superheaters design generally consists of 180° coils welded through the headers on both the sides. In a coil type designs steam is inside the coil and flue gases are outside the coil.

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.

Designing Parameters of Industrial Superheaters

• Boiler pressure
• Steam pressure
• Temperature requirement in the process

Description:
In power station boilers, the effect of superheaters is to heat the steam to certain temperature for higher efficiency of the power station. Reheaters are steam superheaters to reheat the over-worked long-pressure or middle-pressure steam to certain temperature. The use of rehearters can further improve heat power of the power station circulating and control the steam temperature of the end blades of the steam turbine within allowed range. Zigzag superheaters and reheaters of the Company are also unique with rigorous production technique, first-class production flow line and complete test methods.
