Carbon Steel Boiler Superheater Coils for Industrial Boiler and Incinerator
Product Introduction of Boiler Superheater Coils
A superheater is a component that heats saturated steam in an industrial boiler, turning it into superheated steam. Our superheater guarantees that the superheated steam temperature will fluctuate to within an allowable range (normally varies from 540℃ to 550℃) when the boiler is over loaded.
The reheater returns the exhaust steam from high-pressure stage of a turbine back to the boiler for reheating, then sends the reheated steam to the low-pressure stage of a turbine. Through this process, the steam temperature in a turbine is controlled to within an allowable range.
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.
Type of Superheater and Reheater
According to the heat transfer mode: convection, radiation and semi radiation
According to the structural characteristics: serpentine tube type, screen type, wall type and wrapped wall type.
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
Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.
