abstract

One key to the production of clean, efficient electricity from the combustion of coal-derived fuels is an advanced design, combined-cycle power conversion system. A major element in this system is a gas turbine which can operate at temperatures over 2600 F (1427 C) on synthetic fuels containing both erosive and corrosive species. A concept which can effectively deal with both the high gas temperature and the aggressive atmosphere is Transpiration-Air-Cooling (TAC). TAC turbine vanes and blades utilize a load carrying strut, and a porous metal airfoil through which a protective barrier of cooling air diffuses. Materials engineers are continually seeking alternate materials for the porous airfoil which offer opportunities for further improving TAC turbine efficiency, without sacrificing durability. This paper describes results obtained from tests performed in a corrosion-erosion rig operated under the DOE sponsored HTTT Program. The rig evaluated a series of TAC airfoil materials in a high temperature turbine synfuel environment.
