Steam Turbine

Operation & Maintenance

Course Overview

Steam Turbines of several types, which have widely varying configurations and applications, are used extensively in the process industries. These steam turbines represent a significant part of the capital and operating costs of most plants, so that optimizing their selection is of major economic importance.

The course is devoted to design features, efficiencies, operating characteristics, reliability, and maintenance implications of steam turbine drivers. This course will cover the operating principles of steam turbines, specifications, their design, thermodynamics, effect of efficiency on operating costs, energy usage, effect on plant costs, special materials of construction, selection, troubleshooting, and maintenance.

The course will also cover plant run-length extension surveys, organizing for successful turnarounds and ongoing reliability improvement, and preventive vs. predictive maintenance strategy decisions. The course will provide the participant with a basic, as well as advanced, steam turbine technology inventory required to successfully select, apply, troubleshoot, and maintain steam turbine equipment.
