The 700?C steam turbine power plant ? status of development and outlook
This paper appraises the current development status of the 700?C steam power plant under consideration of process optimisation as well as design aspects of the steam turbine and steam generator. The results for a compact arrangement of the steam turbine and steam generator are also presented. Based on a cycle analysis, a net efficiency between 49.3% and 51.4% can be achieved with the 700?C steam power plant ? depending on the implementation and based on an inland plant site. No competing development activities for the 700?C steam power plant are known from the USA or Japan.
