Unit Description and General Aims

Gas Turbines prime are vital pieces of equipment in many industries. Engineers must have knowledge of them; either superficially, or in depth, depending on the engineer’s area of responsibility. The former will be for basic operation and minor maintenance, the latter for installation and heavy maintenance of the units.

In this topic the first aspect addressed is as to where, or if, gas turbines are needed in preference to other prime movers. This depends on the processes being supported, location, expected reliability level, financial considerations and environmental effects. Students will be given templates to help them make calculations leading to correct decisions.

This unit will cover the operation and maintenance of gas turbines. Components covered will include gas compressor types (centrifugal, axial and mixed flow), combustor designs, turbines and exhaust systems. The selection of materials for improved power, efficiency and engine life will be covered. Aero-thermal operations will be studied. The student will also learn about heat recovery systems, COGEN and Combined Cycle. As well as the many systems that makes up any gas turbine installation. Gas turbine operation will be covered, with maintenance, inspection and repair practices, especially where in-house actions can bring about significant savings vis-a-vis contracting these activities to OEMs.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

  1. Critique the economics, and other factors, for installing gas turbines in preference to other prime movers.

  2. Evaluate in detail the construction of a gas turbine engine, its major components and their aero-thermal interactions.

  3. Judge all gas turbine operating phases and be able to discover where both minor- and major maintenance is necessary.

  4. Analyse existing -and recommend - new applications for gas turbines. To be able to evaluate, from given data, efficiencies and economic feasibilities of Combined Cycle as well as COGEN facilities.

  5. Compare and organise information to optimise both gas turbine operation and maintenance practices and reflect on the veracity of information and commercial and regulatory implications on its use.

  6. Design a rudimentary gas turbine using one of several available design packages.

The Engineering Institute of Technology (EIT) is dedicated to ensuring our students receive a world-class education and gain skills they can immediately implement in the workplace upon graduation. Our staff members uphold our ethos of honesty and integrity, and we stand by our word because it is our bond. Our students are also expected to carry this attitude throughout their time at our institute, and into their careers.
