Superheated Steam. The steam is then described as superheated by the number of temperature degrees through which it has been heated above saturation temperature. Superheat cannot be imparted to the steam whilst it is still in the presence of water, as any additional heat simply evaporates more water. The saturated steam must be passed through an additional heat exchanger. This may be a second heat exchange stage in the boiler, or a separate superheater unit.
