Abstract: This paper introduced the application of back pressure steam turbine in the circulating water system of thermal power
station, analyzed the effect of changing the driving device of circulating water pump from motor to back pressure steam turbine in
reducing the power consumption rate, improving the utilization rate of steam and reducing the standard coal consumption of power
supply of power station, realized the goal of reducing cost and increasing efficiency, and provided a reference example for the
enterprise to realize the "green factory" in the energy-saving transformation of equipment.

Key words: circulating water pump; driving device; back pressure steam turbine; energy-saving transformation
