Product Description of Superheater Coil
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres).
Reheaters and superheaters are a set of tubes located in the boiler. Steam from the water walls passes to the superheaters where it is heated above its saturation temperature until the maximum required operating temperature is achieved. The superheated steam then flows through the main steam piping to the high-pressure turbine. Exhaust steam from the high-pressure turbine is guided to the boiler for reheating and from there to the intermediate and low-pressure turbines. High reheating temperatures improve the output and efficiency of a power plant.
Super Heater Types:
A radiant superheater is placed directly in the combustion chamber.
A convection superheater is located in the path of the hot gases.
A separately fired superheater, as its name implies, is totally separated from the boiler.
Details of Superheater Coil
All the raw materials will be firstly made pipeline cutting.
It is consisted of a series of bare oil(carbon steel,alloy steel,or durable heat steel) and header and other auxiliaries. TubesΦ32,38,42 and so on,also as the request.
With the artistic apperance and accurate size,the advance process for bending tube and welding,the first rate test equipment and sophisticated technology
Differences of Superheater Coil
| 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 of Superheater Coil
use for heating saturated steam, steam temperature could be up to 900 degree C.
Superheater Capacity Upgrades to Increase Power Generation
Workshop
Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.
