A superheater is a device used to convert saturated steam or wet steam into dry steam used in steam engines or in processes, such as steam reforming. There are three types of superheaters namely: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres or some hundred metres).
