Saturated, Wet, and Superheated Steam in Paper Drying
It is ideal for heat transfer, but saturated steam leaving the boiler can lose heat in the steam piping and arrive to the dryer as very wet steam. Wet steam occurs when saturated steam and condensate water molecules are mixed. Often, heat loss in piping causes some of the saturated steam to condense and create a steam/water mix.

Papermaking PAPERMACHINE – DRYING Introduction
"web" at the dry end of a paper machine is only half that at the wet end. Thus, the "falling rate" stage is due in part to diminished heat transfer. This occurs because water evaporation away from the hot surface creates a layer of dry paper in contact with the roll. Dry paper is a poor conductor of heat; indeed, it is a good insulator.
