This course provides a comprehensive understanding of regenerative feed heating and condenser systems as essential elements for improving the efficiency of steam power plants. It begins with the limitations of the Carnot cycle and introduces the Rankine cycle, addressing internal and external irreversibilities, mean temperature of heat addition, and systematic methods of efficiency improvement through regeneration and ideal regenerative heating. The course then focuses on practical regenerative heating, covering feedwater heaters, their advantages, impact on cycle efficiency, and optimization considerations. Detailed coverage includes the actual regenerative Rankine cycle, feedwater heater terminology, classification, working principles, and performance parameters such as Terminal Temperature Difference (TTD) and Drain Cooler Approach (DCA). Construction features, thermal design methodology, materials of construction, and applicable codes and standards are discussed along with extraction systems and turbine protection. The specialization further covers surface and air-cooled condensers, addressing design aspects, heat load calculations, performance curves, layout considerations, and practical case studies for real-world application.
