SAVINGS FROM REPLACING AN INDUCTION MOTOR DRIVE WITH A STEAM TURBINE DRIVE
In a steam plant utilizing a deaerating feedwater heater and live, low pressure steam to heat the water, a tremendous cost savings can be achieved by converting one or more electric motor-driven pumps to a steam turbine drive. Exhaust steam from the turbine can be used to supply the deaerator (or other low pressure steam load such as building heat, absorption chillers, etc) eliminating the need for running an electric motor.
The following table illustrates the cost savings that can be achieved for various horsepower motors and various electric rates. The steam cost used for this table is $8.00 per thousand pounds. Greater savings can be achieved if the steam cost is lower than $8.00. Greater savings can also be achieved if electric cost is higher than $0.10/kwh.
