Course Overview

How important is a steam turbine? A steam turbine permits steam to expand and attain high velocity, which in turn is converted to mechanical energy for significant use in industries. Steam turbines are important parts of plant utility systems, and most operations cannot proceed without them.

What purpose does a centrifugal compressor serve? A centrifugal compressor is a sub-class of turbomachinery that achieves a rise in pressure by adding kinetic energy to a continuous flow of fluids through the roller or impeller.

Operation of centrifugal compressors considerably depend on speed, horsepower and driver type. They form an important part of essential turbomachinery and hence should be maintained and repaired if needed.

This Zoe training course will empower you with complete information and understanding of steam turbines and centrifugal compressors. Through this course, you will acquire the required knowledge, experience and skill to work with steam turbines and centrifugal compressors and would be able to contribute to your organisation by ensuring their optimal operation and conducting regular maintenance and repair to prevent huge losses for the organisation.

This, in turn, will demonstrate your skill and ability to oversee the operation of all processes, providing opportunities for senior roles and responsibilities not just in your organisation but others too.
