Abstract
A method of operating a turbine, the method including the steps of: 1) gathering measured creep data for a blade while the turbine operates at different operating temperatures, the measured creep data comprising at least a measured creep rate for the blade (wherein the different operating temperatures include at least a first operating temperature and a second operating temperature); and 2) given the measured creep data for the blade while the turbine operated at the first operating temperature and the measured creep data for the blade while the turbine operated at the second operating temperature, determining whether operating the turbine at the first operating temperature or the second operating temperature is more economically efficient.
