Characteristic Analysis of Francis-Turbine in cooling tower

摘要

The water turbine stands in the cooling water system and drives the fan in the cooling tower, so its flow rate, head and output is limited to the flow rate of cooling water, saved-energy of pump and input of fan separately.The spiral casing dimension of water turbine is limited to the diameter of tower.All above facts make the water turbine of cooling tower be different to that of water power station.The paper introduces one turbine which flow rate is 0.139m/s.Its characteristic of flow passage and hydraulic performance is analyzed, and some new flow passage to improve hydraulic performance is suggested.
