Meanwhile, superheated steam is created when saturated steam flows out of the drum of the boiler and into a secondary heating area called a superheater. The secondary heating brings the saturated steam beyond the saturated steam curve and into the superheated steam area, which results in no moisture (or wetness) in the steam at all.
