ASME Certificated Superheater And Reheater , Coal Fired High Efficient Heat Exchanger
Product Description of Superheater Coil
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. Repeater 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.
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.

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.
