High Quality Steel Heat Exchanger Tube Superheater Reheater For
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
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
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.
