Product Description of superheater coil
1.A super-heater is a device used to convert saturated steam or wet steam into superheated steam or dry steam.
2.It is used in power stations.
3. Super-heaters are used in steam engines or in processes, such as steam reforming.
4.There are three types of super-heaters: radiant, convection, and separately fired. A super-heater can vary in size from a few tens of feet to several hundred feet (a few meters to some hundred meters).
1.Re-heaters are the same as the super-heaters but as their exit temperature is a little bit less than super-heaters and their pressure is 20%-25% less than the super-heater, they can stand less quality material alloys.
Differences of superheater coil
|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|
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.|
Carbon steel, alloy steel or heat-resistant steel, collection boxes and other supporting material. Tubes are customized types of specifications.
Vertical or horizontal layout.
Beautiful appearance, size, accuracy, first-class bending and welding technology, first-class detection equipment.
