Heat Efficiency Heat Exchange Boiler Parts Superheater And Reheaters For Powe Station,ISO/ASME Certification
Product Introduce
Superheater
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.
Reheater
Reheater is a kind of steam superheater that reheats the
low-pressure steam that has done work and reaches a certain
temperature. The role of reheater further improves the thermal
efficiency of power plant circulation, and makes the steam
temperature of the final stage blade of steam turbine controlled
within the allowable range.A reheater is a boiler that heats steam
from a steam turbine to superheated steam.There are two functions
of reheater: one is to reduce the humidity of steam, which is
conducive to the protection of turbine blades;Second, the relative
and absolute internal efficiency of steam turbine can be improved.
Product Advantages
Superheater
1. The dry saturated steam drum to further make the superheated steam heating. When the soda coexist, the soda heating the mixture, add heat can only be used to make soda water evaporate into steam in the mixture, and cannot make steam temperature of superheated steam. To get to the superheated steam, the commonly used method is to steam separated from the mixture of soda, for its further heating, accomplish this task components become the superheater.
2. reduce the temperature of flue gas, recover the heat in the flue gas, improve boiler efficiency.
Reheater
1. Reduce the humidity of steam, which is conducive to the protection of turbine blades.
2. Relative and absolute internal efficiency of steam turbine can be improved.

Type Advantages Disadvantages Supporting Method
Pendant-type
1.Firm structural support
2. Flow blockage by condensed steam
3. Needs slow restart to purge the water that accumulates in the
bottom. supported from above
Inverted-type
1.Proper drainage of the condensed steam
2. Lack the structural rigidity, especially in high speed gas flow
Supported from below
Horizontal -type
1. Proper drainage
2. Good structural rigidity.
They do not view the flam directly so they are mainly from the
convective type Usually supported in the vertical gas ducts
parallel to the main furnace.
Design Structure
1. heating saturated steam, temperature up to 900 degree C.
2. high efficiency, >90%.
3. high speed heating.
4. design with stainless steel.
5. long design service life, 15 years.
