Review on design and selection of pump for super critical thermal power plant project

Designing and selecting pumps for supercritical thermal power plants is crucial for efficient, reliable power generation. This review paper examines key considerations in selecting pumps for supercritical thermal power plants, which operate at higher pressures and temperatures than subcritical plants. It explores pump types like boiler feed, condensate extraction, and cooling water pumps, focusing on their roles and operational needs in supercritical conditions. The paper discusses critical design factors, including material selection, hydraulic performance, and mechanical integrity, which influence pump efficiency and longevity. It also addresses challenges such as cavitation, wear, and thermal stresses in supercritical environments. The review highlights current technologies, best practices, and innovative solutions to enhance pump reliability and performance. It examines the economic aspects of pump selection, balancing initial investment with long-term operational costs, and guiding engineers to optimise performance and cost-effectiveness. The findings aim to assist engineers and decision-makers in the thermal power industry, helping them make informed choices that optimise performance, reliability, and cost-effectiveness in supercritical power plant projects.
