Embodiment example
[0025] An industrial park needs to provide the enterprises in the park with saturated steam for production. The hourly demand is 35 tons and the steam pressure is 0.6 MPa. The main steam pressure provided by the boiler in the park is 2.35 MPa and the temperature is 400 °C. The main steam is desuperheated and decompressed by the back-pressure centrifugal turbine, and the turbine drives the generator to output electric energy. The exhaust pressure of the turbine is 0.6 MPa, and is further reduced in temperature by spraying water, and then sent to the steam user after reaching saturation. If the single-impeller type centrifugal turbine is used, the size of the impeller is large and the rotational speed is also high, which is difficult to meet the requirements of balancing the axial force and ensuring the stability of the rotor dynamics. The parallel double-head separately exhausted centripetal turbine of the present invention is used here. The inlet and exhaust parameters of each...
