The development of efficient energy conversion systems is important for energy saving and emission reduction. The power cycle is the key component of the energy conversion system. Its performance and different forms of structure are significant that affecting the overall efficiency of the energy conversion system. In recent years, the supercritical CO2 (S-CO2) Brayton cycle is expected to replace some traditional steam Rankine cycles. It can be applied in different energy industries due to its advantages of small size, low cost, and high efficiency.
In this lecture, theoretical level and application level of the S-CO2 Brayton cycle’s development in different energy industries are studied primarily. It mainly includes the applications in nuclear power plants, solar power plants, thermal power plants, and energy storage systems etc.. Second, some relevant works developed by the lecturer are introduced, such as the thermal-economic performance analysis of S-CO2 Brayton cycle, the multi-parameter/multi-objective optimization, different effective methods for improving the energy conversion efficiency and utilization efficiency of S-CO2 Brayton cycle.
