High-Performance Superheater Coils For Stable Steam Output In Power
Plants
Why are superheaters and reheaters critical for power plants?
They increase steam enthalpy, boosting turbine output and fuel
efficiency.
Product Function&Features
HDB thermal efficient steam super heater for coal fired boilers
Specification:
Superheaters stand as pivotal boiler spare components,
significantly enhancing thermal efficiency. High-temperature steam
boiler radiant superheaters are typically utilized in high-pressure
power plant boilers.
Within a boiler, the superheater functions to heat saturated steam
to a specified temperature of superheated steam, thereby boosting
power plant efficiency. The reheater essentially serves to further
enhance the thermal power plant cycle efficiency.
Steam Superheater Coils: These coils are employed in boilers to
convert saturated steam into superheated steam, with specific
application in power plant boiler systems. We produce superheater
coils using multiple grades of alloy steel and stainless steel
tubes, offering configurations with or without supports and headers
as per customer-provided drawings.
Changes in boiler operating conditions, such as load level, fuel
change, combustion condition change, etc., all have an impact on
superheater outlet steam temperature, so in power station boilers
there are means to adjust boiler outlet steam temperature to make
it stable at the specified value.Commonly used means are:
(1) with water jet or surface type temperature reducer directly
adjust the steam temperature;
(2) with the swing burner to change the temperature of the furnace
outlet smoke;
(3) with smoke recirculation adjustment superheater heat
absorption.When the boiler load increases, the temperature rise
value of the inlet and outlet steam of the flow superheater
increases, while the temperature rise value of the radiant
superheater decreases.
When convective, radiant, and semi-radiant superheaters are
optimally set up and combined, outlet steam temperature stays
steady—even with load or combustion changes.
In operation, parallel tubes in the superheater stack absorb heat
and let steam flow at different rates. To prevent overheating in
single tubes, big boilers split the superheater into multiple tube
banks. Steam from each bank mixes via an external furnace manifold,
and guide pipes transpose banks, keeping tube temperature
differences small.
Superheater&Reheater, Custom Component For Boiler Superheater
Coil
Superheater is a part of a boiler that heats the steam from the
saturation temperature to the overheating temperature. It is also
called a steam superheater.Superheater can be divided into
convective type, radial type and semi-radial type according to heat
transfer mode;According to the characteristics of the structure, it
can be divided into serpentine pipe type, screen type, wall type
and wall type.They are made up of parallel pipes and inlet and
outlet manifold.
Most industrial boilers do not have superheaters because many
industrial processes and living facilities require only saturated
steam.In power stations, locomotives and Marine boilers,
superheater is usually installed to improve the circulating thermal
efficiency of the whole steam power plant.
