Superheater Coil Introduce


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.

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.

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.




Product Details


1 Material composition Carbon steel, alloy steel or heat-resistant steel, collection boxes and other supporting material. Tubes are customized types of specifications.
2 Design pattern Vertical or horizontal layout.
3 Advantages Beautiful appearance, size, accuracy, first-class bending and welding technology, first-class detection equipment.


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.
