Mechanisms of Gas Turbines is a free online course that begins by introducing you to the fundamental principles of starting systems, as well as starting system procedures and precautions for a gas turbine. This course will introduce you to start-up control main features,along with the concept and characteristics of electric starters. This course will teach you about new technological advances to electric starters. You will learn about the features and functionality of GE’s starting systems which include; engine start, motoring/purge, water wash, and borescope. The functions, features, as well as operations of pneumatic starters, will be covered in this course. This course will also introduce you to the components and disadvantages of a hydraulic start system which include; complexity, system weight, flammability of hydraulic fluids, as well as the existence of high-pressure hydraulic lines. This course will teach you about hydraulic start system operation, alongside functions of the hydraulic oil charge pump, charge pump filter, and main hydraulic oil pump. The hydraulic starter motor, centrifugal starting clutch, and pre-start inspection steps will also be covered in this course.
This course then explains the quantity of lubricating oil and oil consumption in a gas turbine. You will learn about the two types of lubricating oil for gas turbine applications which include; standard and corrosion inhibiting. This course will teach you about the harsh conditions the lubrication oil in gas turbines is subjected to which include; extreme heat, high contamination, and inadvertent mixing with substances.. The two types of lubrication systems; wet-sump and dry-sump systems, along with their uses will be covered in this course. This course also explains the lube oil flow, components of the lube supply subsystem, lube scavenge subsystem, and a lube oil system schematic. You will also learn about the characteristics and requirements of fuel, as well as the maintenance and handling of fuel. This course also explains the types of fuel oil to use in a gas turbine system which includes; LNG, LPG, ethane, and pure hydrogen. The functions and components of the fuel system will also be covered in this course. This course will also teach you about the requirements for a marine gas turbine engine which include; starting, engine steady running requirements, as well as engine acceleration and deceleration.
Furthermore, this course will help you get familiar with detection methods used for typical transducer faults which include; speed and temperature transducers. This course will also teach you about the working systems, features, and functions of the spark ignition system. You will also be familiar with the importance of power turbines, and the significance of SSS clutch in starting the operation of the turbine. The functions and types of epicyclic gears which include; star gear, planetary gear, and solar gear will also be covered in this course. This course will also teach you about the advantages of using multiple-planet wheels. Including the functions and types of clutches which include; twin-disk, air flex, hydraulic, sprag, and SSS clutch. You will also be familiar with the purpose of the bleed air system, as well as the functions of the intake and exhaust system. You will learn about the functions, components, and data processing system of the automated central operating systems (ACOS). This free online course will be of great interest to students, researchers, and anyone with an interest in the mechanisms of gas turbines So, register for this course and start your next learning journey today.Start Course Now
