ASME Boiler Superheater Coil Tubes Of SA179 For Maintenance And Replacement
Description
Superheater is a component in a boiler that further heats steam from saturation temperature to superheating temperature, also known as a steam superheater. Superheaters can be divided into convection type, radiation type, and semi radiation type according to their heat transfer methods; According to structural characteristics, it can be divided into serpentine tube type, screen type, wall type, and enclosed wall type. They are all composed of several parallel pipes and inlet and outlet headers.
Most industrial boilers are not equipped with superheaters because
many industrial production processes and living facilities only
require saturated steam. In power plants, locomotives, and marine
boilers, superheaters are generally installed to improve the cyclic
thermal efficiency of the entire steam power plant.
There are different types of super heaters with advantages and
disadvantages as below:
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. |
For over 30 years, Hua Dong Boiler has been consistently innovating and improving our boiler superheaters and reheaters. The improvements in bending, welding and design ensure our products meet both European and American standards, ensuring a reliable performance.
