Its application is of great significance to improving energy utilization efficiency, reducing production costs and reducing environmental pollution. Turbine blades are important components in turbine machinery that guide fluid to flow in a certain direction and drive the rotor to rotate. The blades of the BPRT unit turbine play a key role in its working process. The unit is a blast furnace axial flow compressor unit, mainly used to convert thermal energy into mechanical energy. In this process, high-temperature and high-pressure gas enters the turbine through the turbine part and expands therein, thereby realizing energy recovery and utilization. The design features of the BPRT unit include the use of a dry turbine and a combined use with a pressure reducing valve, which helps to simplify the system structure, improve unit efficiency and reduce floor space.
