【 摘 要 】

Recuperators have been identified as key components of advanced gas turbines systems that achieve a measure of improvement in operating efficiency and lead the field in achieving very low emissions. Every gas turbine manufacturer that is studying, developing, or commercializing advanced recuperated gas turbine cycles requests that recuperators operate at higher temperature without a reduction in design life and must cost less. The Solar Cooperative Research and Development of Primary Surface Recuperator for Advanced Microturbine Systems Program is directed towards meeting the future requirements of advanced gas turbine systems by the following: (1) The development of advanced alloys that will allow recuperator inlet exhaust gas temperatures to increase without significant cost increase. (2) Further characterization of the creep and oxidation (dry and humid air) properties of nickel alloy foils (less than 0.13 mm thick) to allow the economical use of these materials. (3) Increasing the use of advanced robotic systems and advanced in-process statistical measurement systems.
