From that article: "but such wet-steam conditions have to be limited to avoid excessive turbine blade erosion" See also the article "vapor quality" on wikipedia, in particular the section of steam quality, where you find: "The genesis of the idea of vapor quality was derived from the origins of thermodynamics <http://en.wikipedia.org/wiki/Thermodynamics>, where an important application was the steam engine. Low quality steam would contain a high moisture <http://en.wikipedia.org/wiki/Moisture> percentage and therefore damage components more easily[*citation needed<http://en.wikipedia.org/wiki/Wikipedia:Citation_needed> *]. High quality steam would not corrode<http://en.wikipedia.org/wiki/Corrode> the steam engine. Steam engines <http://en.wikipedia.org/wiki/Steam_engine> use water vapor (steam <http://en.wikipedia.org/wiki/Steam>) to drive pistons which create work. The quality of steam can be quantitatively described by *steam quality* (steam dryness), the proportion of saturated<http://en.wikipedia.org/wiki/Saturation_(chemistry)> steam <http://en.wikipedia.org/wiki/Steam> in a saturated water/steam mixture.[4] <http://en.wikipedia.org/wiki/Steam_quality#cite_note-3> i.e., a steam quality of 0 indicates 100% water while a steam quality of 1 (or 100%) indicates 100% steam." Steam can be wet. Live with it.
