Abstract
The Steam Turbine: A basic description of how a steam turbine converts available heat into mechanical energy to
define the formulae used for the cost comparisons in the subsequent examples.
Co-Generation: Comparison between condensing cycle and back pressure turbine exhausting to useful process, identifies potential energy savings.
Process Power Recovery: Replacing pressure reducing valve with steam turbine produces mechanical or electrical energy in conjunction with process heat.
Steam vs. Electric Motor: Comparison of electric motor operating cost with steam turbines to show that cost-savings depend on application.
Waste Heat Recovery: The addition of a steam turbine can justify waste heat projects that were previously not feasible
on an economic basis.
