Advances in super critical power generation 2006

AbstractEuropean efforts to start substantial improvements of the performance of well established supercritical coal fired power technology named the AD700 project started in the mid 1990s. Major targets were development of austenitic materials and nickel based superalloys for the hottest sections of boilers, steam lines and turbines. Other targets were development of boiler and turbine designs for the more advanced conditions and finally economic viability of the AD700 technology has been investigated. The project has been very successful and 40 partners from the European power industry have worked together in several projects cofunded by the European Commission for >10 years. Procurement of mature and commercially optimised AD700 plant could take place around 2015. The investigated nickel based materials have shown very high creep strengths but they have also shown to be very hard to manufacture, and more efforts to define new machining lines are being started. Ongoing tests indicate that the developed ...
