Gas Turbine Operation, Applications, Operation, Maintenance & Troubleshooting
The gas turbine is the most versatile item of turbomachinery today. It can be used in several different modes in critical industries such as power generation, oil and gas, process plants, aviation, as well as domestic and smaller related industries. A gas turbine essentially brings together air that it compresses in its compressor module, and fuel, which are then ignited. Resulting gases are expanded through a turbine. That turbine’s shaft continues to rotate and drive the compressor which is on the same shaft, and operation continues. This course is designed to provide engineers, operators, mechanics, technicians, and supervisors the desired kind of training in gas turbines application, operation, installation, maintenance, and troubleshooting.
This course is designed to provide the attendants with basic and deeper knowledge about gas turbines in general with emphasis on their operation, maintenance and inspection. Specifically, by attending this course you will:
