Steam and gas turbines as compressor, pump and generator drivers, and the case for a turbine over a motor. Covers how the plant steam balance influences driver selection alongside reliability and availability.
Energy conversion from steam enthalpy to shaft work, and the difference between impulse and reaction staging. Covers velocity triangles at a practical level and how steam rate is interpreted.
Condensing, back pressure and extraction turbines and their steam balance implications. Covers single against multistage, and the difference between API 611 general purpose and API 612 special purpose machines.
The Brayton cycle in its practical form, and the compressor, combustor and turbine sections. Covers single shaft against two shaft machines and aeroderivative against heavy duty industrial designs.
Steam rate and efficiency and how they vary with load, inlet and exhaust conditions. Covers the Willans line, part load performance penalty and extraction turbine behaviour across the operating map.
Power output and heat rate, and how ambient temperature, pressure and humidity affect them. Covers inlet air cooling, site rating against ISO rating, and the summer derating that surprises operators.
Gas turbine compressor fouling and steam turbine blade deposits and erosion. Covers online and offline washing, performance trending as the diagnostic, and the economics of recovery against continued degradation.
Heat recovery steam generation from gas turbine exhaust and combined cycle efficiency. Covers cogeneration, the process steam interface and the plant integration decisions that follow driver selection.
Rotor construction, blade attachment and blade materials with their temperature limits. Covers steam path sealing, labyrinth glands, casing design and thermal growth.
Journal and thrust bearing arrangement and hydrodynamic behaviour at speed. Covers thrust load sources in a turbine, bearing instrumentation and the failures that occur.
Labyrinth gland design and leakage, and gland steam and condenser systems for steam turbines. Covers dry gas and oil seals in gas turbine applications and the failures that cause emission or contamination.
Combustor design and liner life, nozzle and blade cooling, and hot section materials and coatings. Covers hot gas path inspection intervals and the degradation that drives major overhaul scheduling.
Governor function and speed droop, and mechanical, hydraulic and electronic governing compared. Covers steam valve arrangement and sequencing and the interface with the driven machine control.
Overspeed as the primary turbine hazard, and mechanical against electronic overspeed trip. Covers trip test requirements, API 670 protection, voting philosophy and the incidents that shaped current practice.
Lube oil console design and redundancy, and control and trip oil systems. Covers coolers, filters and accumulators, API 614 requirements, and the auxiliary failures that trip the machine.
Steam quality requirements, moisture removal and the importance of superheat. Covers gas turbine fuel systems, dual fuel arrangements and fuel gas conditioning reliability.
The scope and application of API 611, 612 and 616 and the general against special purpose distinction. Covers the datasheet, rotordynamic analysis requirements and vendor documentation review.
Mechanical running test acceptance criteria and the practical difficulty of performance testing. Covers overspeed trip testing, string testing with the driven machine, and what to witness against what to accept on certificate.
Steam blowing and its purpose, turning gear and rotor bow avoidance. Covers warm-up and load ramping constraints, the first start sequence, and the damage caused by rushing a start.
Inspection and overhaul intervals and their basis, and hot section replacement for gas turbines. Covers blade and rotor repair and the systematic diagnosis of vibration, performance loss and trip events.
This course contains the use of artificial intelligence.
A turbine driver is chosen at concept stage and lived with for thirty years. Get the selection wrong and the steam balance, the plant availability and the maintenance budget all inherit the decision.
Most engineers meet turbines already installed and running, with no idea why that machine was chosen or what its operating envelope actually is.
In this course you will learn how the selection was made, how the machine performs, and what will stop it.
WHAT YOU WILL LEARN TO DO
By the end of this course you will be able to:
● Select between steam and gas turbine drivers, and between condensing, back pressure and extraction configurations
● Read a steam rate figure and understand what it tells you about part load performance
● Assess gas turbine output against ambient conditions and understand the derating that follows
● Diagnose performance degradation and decide between washing, cleaning and continued operation
● Specify overspeed protection and understand the trip philosophy behind it
● Interpret API 611, 612 and 616 requirements and challenge a vendor proposal against them
● Plan a turbine start, including warm-up constraints and rotor bow avoidance
● Determine what to witness at a works test and what to accept on certificate
HOW THE COURSE IS TAUGHT
● Turbine behaviour explained from energy conversion upward, without the derivations
● Performance and degradation treated as an operating problem rather than a design curiosity
● No software needed — the methods transfer to any vendor's selection tool
● Five section quizzes and a final exam
● Every presentation is included as a downloadable PDF, so you keep the slides as a desk reference after the course
● Built around the failures that actually take turbines out: overspeed, hot section and lube oil
WHAT IS COVERED
● Where turbines beat motors as drivers, and the steam balance that often decides it
● Steam turbine fundamentals — impulse and reaction staging, velocity triangles and steam rate
● Condensing, back pressure and extraction configurations and their plant implications
● Gas turbine fundamentals — compressor, combustor and turbine sections
● Single shaft against two shaft, and aeroderivative against heavy duty industrial
● Performance across load, and the Willans line as a practical tool
● Ambient temperature, pressure and humidity effects, and inlet air cooling
● Degradation, compressor fouling, washing and the economics of recovery
● Rotor, blading, casing, bearings, seals and gland systems
● Gas turbine hot section — combustor, cooling, materials and inspection intervals
● Governing, speed control and the interface with the driven machine
● Overspeed protection, trip testing and the incidents that shaped current practice
● Lubrication, control oil and the auxiliary failures that trip the machine
● API 611, 612 and 616 requirements, testing, commissioning and overhaul
WHO THIS IS FOR
● Rotating equipment engineers responsible for turbine-driven trains
● Process and utilities engineers whose steam balance depends on turbine selection
● Operations engineers running turbine-driven compressors, pumps and generators
● Maintenance engineers planning turbine inspection and overhaul
● Project engineers specifying drivers and reviewing vendor proposals
ABOUT YOUR INSTRUCTOR
I am a Chartered Engineer (CEng MIMechE) with over fifteen years in oil and gas, energy and industrial infrastructure, across a range of projects and disciplines.
For more than five years I have also been teaching. Close to twenty thousand engineers have taken my courses, which hold an average rating of 4.26 across the catalogue.
I build these courses because I am genuinely interested in how engineering works and why it fails, and because most technical subjects are taught far worse than they need to be. My aim every time is to produce the course I would have wanted when I first met the subject — practical, honest about what actually matters, and free of the padding that wastes your time.
REQUIREMENTS
No prior turbine experience is required — energy conversion and staging are built from first principles. Any engineering or technical background is enough to follow it.
