Thermal and stress analyses of a novel coated steam dual pipe system for use in advanced ultra-supercritical power plant

Improving the energy efficiency of advanced ultra-supercritical power plants, by increasing steam operating temperature up to 700 °C, can be achieved, at reduced cost, by using novel engineering design concepts, such as coated steam pipe systems manufactured from high temperature materials commonly used in current operational power plants. This paper describes a preliminary feasibility analysis of the design concept of a novel coated dual pipe...
