Steam Turbine Retrofit Savings


CONVERT TO ELECTRONIC SPEED CONTROL OF YOUR STEAM TURBINE AND ELIMINATE COSTLY GOVERNOR AND GOVERNOR VALVE REPAIRS.

Regardless of the age or size of your steam turbine, you no longer need to contend with long lead times for parts and costly repairs to your speed control governor and governor throttle valve assembly. An electronic speed control system eliminates the standard mechanical or oil relay governor and the standard governor throttle valve assembly. Our electronic system is PLC-based using standard, off-the-shelf control valves for the inlet steam supply. This systems costs thousands of dollars less than the conventional system, has only one moving part and can also incorporate overspeed trip control for your machine.

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.
