Steam Inlet Temperature an overview ScienceDirect Topics

3.8 Material issues in the development of advanced steam plants. To attain a net efficiency of 50% a typical steam plant in northern Europe would require an inlet steam temperature in the 700–720 °C range at a steam pressure of 350 bar. In the USA because cooling water temperatures are high, steam conditions are even harsher at 760 °C/350 bar.
