Coal contributes to about 70% of power generation, which is an abundant and low-cost resource. The combustion of coal emits environmentally polluting gases, which is found to reduce by adopting pressure vessels with increased temperature and pressure in thermal powerplants. Advanced Ultra-Supercritical based pressure vessels can handle such extreme pressures and temperatures. AUSC technology is found to improve the efficiency and helps to exceed the 50% net efficiency barrier. However, at this temperature range, the strength of conventional materials used in pressure vessels, turbines, etc. is found to be insufficient. The proposed research is intended to develop a detailed Finite Element model that can accurately predict the structural integrity, the temperature-induced Creep behavior, and Fatigue strength of such pressure vessels used in AUSC technology.
