Superheater Coil Description

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.
