Steam Turbine Efficiency & Design

This lecture covers the efficiency and design aspects of steam turbines, focusing on parameters such as isentropic efficiency, turbine characteristics, and boiler design. It discusses the impact of operating conditions on turbine performance, including the influence of losses, geometry parameters, and dimensionless parameters. The presentation also delves into the condensing and preheating systems in steam power plants, emphasizing the importance of vapor extraction for feedwater preheating and economizer preheating systems. Additionally, it explores the off-design characteristics of steam turbines, highlighting the factors affecting isentropic efficiency and specific work in turbine operation.
