You taught and encouraged me. The vision I gained from working with all of you is the basis for much of this book. In the years since I assembled the first edition of this book, gas turbine hardware remains, in principle, as it was then. True, a few major manufacturers have developed and released their J-category technology and with this come the refinements in metallurgy and design that help the J machines achieve their rating.

OEMs get cleverer with exploring waste fluids for fuel, substituting fluids in case of disasters like earthquakes air instead of water for cooling , and a myriad of other adaptations. With aviation and marine applications, there are refinements and improvements as always, but the gas turbine itself stays the same in operating principles. Clearly, I was wrong. Even the major original equipment manufacturers OEMs that were smart enough to survive years of a bad economy and emerge relatively unscathed, had to lose valuable people and expertise in the process.

Some OEMs are still reorganizing and acquiring divisions of smaller competitors. Many smaller players and even related industries have gone under. For instance, about ten years ago, the turboexpander was a small but thriving turbomachinery category.

Due to the specialized metallurgy it had to develop to handle corrosive or cryogenic fluids, it could have contributed much to gas turbine systems technology. Besides, a turboexpander often used what would have otherwise been a wasted stream of by-product fluid to develop power. The wars in the Middle East breathed new life into the excess and used machinery business.

When restructuring Iraq, for instance, the U. This was more expedient than ordering new systems. The wars also shifted attention and development funds to the development of weaponry, surveillance, and other defense electronic systems. World Wars I and II had seen the emergence of the jet engine because of necessity. This then led to the establishment of the peacetime gas turbine business. No similar steep development curve for gas turbine engines came with the Iraq to and the Afghanistan to - wars.

Since money has been short, gas turbine owners are keener to keep what they already own. Even in cases where there has been development like with the J size gas turbines , it is still useful to note the development work that preceded earlier developments.

Global evidence of climate change has increased dramatically in the last decade, causing the United States to step up its drive to promote renewables and increase efficiency in fossil-fueled power plants. It is clear that fossil fuels will be around for another half century at least. The smart grid that promotes the integration of renewables into the power mix is now being constructed in some locations and then the rest of the world will have to catch up.

While still not bending a knee to emissions protocols that were accepted globally, the United States is clearly keen on reducing its emissions and is stepping up incentives and legislation in that vein. Repowering replacing steam turbines with gas turbine combined cycles or even replacing steam turbine coal fuel with gas fuel is on the increase.

The increased availability of gas due to the fracking movement is in part responsible. Since fracking may sometimes be handled by small, ruthless contractors who cut corners and create environmental hazards, fracking has a bad name with the public. If properly regulated and using the technology as it was designed, fracking need not be a nuisance.

Further mass increases in drilling will cause seismic unrest below ground that can have consequences of its own, outside of the fracking process. As a result, gas turbine and gas turbine system developments that favor component life extension, repairability, increased efficiency, fuel flexibility, derating and uprating, working in a hybrid system, better grid distribution, and a host of other items that affect cost of ownership, feature prominently in this second edition. It is clearly a different world than that in which the first edition emerged less than a decade ago.

We ought to consider adapting. The good news is that the gas turbine itself, fuel variations with different IGCC cycles and experiments with new fuels notwithstanding, is now a well-developed and relatively predictable beast.

When OEMs develop newer models like the J machines and their CC packages , they do so around a reliable core, albeit with refinements in design, manufacturing, and sometimes performance testing. Some of my OEM friends chuckle at the reduced level of gas turbine expertise among end-users although there are always exceptions , but quite apart from the growth of power-by-the-hour and similar contracts, the end-user engineer can often get by with knowing less than one had to, two or more decades ago.

One friend who retired from a major OEM went back to teach young gas turbine design engineers there and commented that the new engineer workforce would never get to do work as challenging and interesting as those who started their careers anywhere between and When I teach courses in industry, I observe that he is frequently right.

I also see a trend among engineers and their management wanting material presented in more visual, easier to assimilate teaching formats. My media hobby skills have grown into a set of media resources in case the client requests animations, and digital videos versus static displays, in courses they order. Does the gas turbine still offer the potential for reduced costs per fired hour?

Fossil fuels are alive and well and will be in use although the renewable mix will increase thanks to smart grids and other factors past the life span of anyone alive today. Refinements with respect to fuel technologies, repair and overhaul, metallurgy, environmental strategy, and emissions economies shall all continue. Emissions taxation and credits will increasingly affect our lives.

Coal as syngas will continue to be refined as a gas turbine fuel. Hence this second edition. The current models of aviation engines on transpacific flights develop about 90, pounds of thrust, power generation gas turbines have broken the megawatt gas turbine barrier, and gas turbines are now being used on cruise ships.

Gas turbines have come a long way since my first meeting with them. At that point over thirty years ago, we waited a day for the casing on an old 20 kilowatt Brown Boveri to cool sufficiently for us to be lowered by rope harness into the intake for an inspection. Most end users do not part easily with their old workhorses, so many of them are still around. To some extent, these turbines owe their longevity to the continual design development in the form of service bulletins, decreed mandatory or optional by their manufacturers.

I use quotation marks, as sometimes there are manufacturers who have used the mandatory label as a means of upgrading end-user fleets for their own revenue extension. And then other times, as with the JT8D, the bulletins developed took a generic 9, pound thrust engine, born in the s to just under 20, pounds thrust by the s with one of the most enviable safety records for a gas turbine fleet.

There are many types of basic applications of gas turbines. There are land, sea, and air gas turbines. On land, there are power generation and mechanical drive gas turbines. In aviation, there are large commercial, high-performance military, mid-range commercial, small fixed-wing, and helicopter engines, maintained to commercial or military specifications. At sea, there are large vessel turbines and smaller ferry turbines. There are offshore applications that must incorporate the sturdiness associated with land use turbines, with the light weight associated with aviation applications, with the corrosion resistance associated with marine applications.

There are many types of engineers who are fortunate enough to work with gas turbines. There are end users and OEMs original equipment manufacturers. Gas turbine specialists and turbomachinery specialists who work on all rotating machinery. Overall systems and project engineers.

And manufacturer design specialists who will work on one major turbine component all of their working lives. There is an indefinable quality about gas turbines that favors those that who somehow develop an instinct for them, regardless of working years spent or formal education accumulated.

I have watched humble mechanics point the way for befuddled technical gurus. There are brilliant design engineers who can miss a misalignment source that a millwright can spot blindfolded. With gas turbines, there are systems design and specification, commissioning, troubleshooting, failure analysis, retrofit and reengineering, training, technical writing, design development, repair and overhaul, fleet management, and regular operations functions.

I have been singularly fortunate in that I have run that entire gauntlet back and forth in power generation, oil and gas, process, military aviation, and commercial aviation on three different continents. No credit to my astuteness: the state of the world kept moving me on politics is a good thing sometimes. One flash of discernment, however, did make it possible for me to hold all of that exposure together not just as a cohesive whole, but one where all sectors could gain from each other.

Then in the Canadian Air Force, I was about to take on all the six helicopter engine fleets the Canadian military branches flew. In Canada, we had just piggybacked on the US F fighter program with a few of the same.

It occurred to me that the panel displayed on the screen was very similar to the one on the HUD head up display of the F It works. The panel has hosted some of the best brains from commercial and military aviation, power generation, oil and gas, manufacturing, process and petrochemical, performance analysis, marine applications, metallurgical development, and controls instrumentation and diagnostics. Those attendees who are fortunate enough to show up have benefited enormously. It has given aspects of my work a rare flair that is attributable to the company I have been blessed to keep.

This book represents much of the expertise in the gas turbine field available today. That latter portion serves to give the reader a point of reference that they can measure the extent of their agreement—or disagreement—against. The book avoids the just-one-application bias say, just mechanical drive or just power generation or just aviation or just plain theory that all other gas turbine books I know of adopt.

Gas turbine engineers in all sectors, disciplines, and specialties, who looked at the draft, have told me they found its contents useful. So besides imparting applications and basic design knowledge, this book is meant to get readers to think across disciplines, across land, sea, and air to the heart of this demanding, powerful, and infinitely variable mistress—the gas turbine.

In this second edition, the single largest factor that is responsible for added material is technology that accommodates a wider range of fuels and fuel parameters in gas turbines GTs and gas turbine including steam turbine cycles. GTs are now on the verge of adopting coal as a fuel, as syngas in an integrated gasification combustion cycle IGCC. Some GTs can handle biomass.

A heavy-duty gas turbine, designed for natural gas, was used to burn the syngas with two different calorific values. This study was mainly to optimize the flow matching scheme for the gas turbine. Two models of gas turbine burning syngas with different calorific values were established and the calculation models of different flow matching schemes were provided. The optimum scheme was obtained by evaluating thermal efficiency and work output under different operating conditions. The results showed that the highest unit efficiency was achieved by, without significant drop in work output, increasing the throat area of the turbine nozzle and reducing the initial temperature of the gas.

Gas Turbines: A Handbook of Air, Land and Sea Applications

A gas turbine , also called a combustion turbine , is a type of continuous and internal combustion engine. The main elements common to all gas turbine engines are:. A fourth component is often used to increase efficiency on turboprops and turbofans , to convert power into mechanical or electric form on turboshafts and electric generators , or to achieve greater thrust-to-weight ratio on afterburning engines.
