The high-temperature reheater is located at the high-pressure cylinder stage of the steam turbine, where it reheats the medium-temperature and medium-pressure steam discharged from the high-pressure cylinder. The reheating temperature in the high-temperature reheater is higher, which can further increase the steam temperature and pressure. With the reheating effect of the high-temperature reheater, the thermal efficiency of the steam turbine can be further improved, and the energy utilization rate is also higher.
