Transforming Steam Technology For Significant Energy and Water Savings. Savings efficiencies reported are from On to Off condition. There is no requirement to heat any tubes or nozzles to produce steam.
Conventional boilers are never 100% dry. Saturated steam has to cool just a bit for condensation to set in - not so with high temperature superheated steam.

A low steam dryness hinders heat transfer.
