Product Description
ASME Standard Stainless Steel Boiler tube Superheater And Reheater Utility / Power Station Using
Product Description
The superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. The superheated steam is used in steam turbines for electricity generation and steam engines etc.
Superheaters are the one of the most important accessories of boiler that improves the thermal efficiency.
In the boiler, the role of superheater is to heat the saturated steam to a certain temperature of superheated steam to increase power plant efficiency. Reheater essentially further improves the thermal power plant cycle efficiency.
Superheater is to increase the temperature of the steam above its saturation point.
Reheater is basically a superheater that superheats steam exiting the high-pressure stage of a turbine. The reheated steam is then sent to the low-pressure stage of the turbine. By reheating steam between high-pressure and low-pressure turbine it is possible to increase the electrical efficiency of the power plant cycle beyond 40%.The reheat cycle is used in large power boilers since it is feasible economically only in larger power plants.

Differences
| Type | Advantages | Disadvantages | Supporting method |
| Pendant-type | 1.Firm structural support | 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. | supported from above |
| Inverted-type | 1.Proper drainage of the condensed steam | 1. Lack the structural rigidity, especially in high speed gas flow | Supported from below |
| Horizontal -type |
1. Proper drainage 2. Good structural rigidity. |
1. 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. |
Application
Use for heating saturated steam, steam temperature could be up to 900 degree C.
Superheater Capacity Upgrades to Increase Power Generation
Functions
1, superheater is the saturated steam heated into a certain temperature of superheated steam equipment.
2. After the saturated steam is heated into superheated steam, the working capacity of steam in the steam turbine is improved, that is, the useful enthalpy of steam in the steam turbine is increased, thus improving the cycle efficiency of the heat engine.
3. In addition, the adoption of hot steam can also reduce the steam exhaust humidity of the steam turbine, avoid the corrosion of the steam turbine blade, and create favorable conditions for the further reduction of steam exhaust pressure and safe operation of the steam turbine.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
