Product Description of superheater coil

• A super-heater is a device used to convert saturated steam or wet steam into superheated steam or dry steam.

• It is used in power stations.

• Super-heaters are used in steam engines or in processes, such as steam reforming.

• 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).

• 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.

Type Advantages Disadvantages Supporting method of superheater coil

• Firm structural support

• Flow blockage by condensed steam

• Needs slow restart to purge the water that accumulates in the bottom. supported from above

• Lack the structural rigidity, especially in high speed gas flow Supported from below

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.
