Gas Turbine Basics Book?

It will be well serve if you can just show where to get these GT/ST/HRSG/CCGT/Rankin Cycle/Braton Cycle and so on vids for self-paced learning have, which I could lend to you. my email is

Working for a utility that has 7EA's and 7FA's, I have found that GE is a good resource for training and technical information regarding their combustion turbines (and steam turbines, for that matter). The site documentation tends to be pretty thorough--much more so then other turbine manufacturers I've encountered--and their on site training is usually high quality, too. (The term high also applies to the price.)

We have an LTSA (long term service agreement) with GE, and they have made available on line interactive training for its LTSA customers called PATAT (for Pro Active Trip Avoidance Training) at no extra cost, which is useful for teaching some of the fundamentals of CT, ST and HRSG operation and maintenance. It covers subjects such as exhaust thermocouple trip logic, the TC's themselves, compressor bleed valves, lean blow out, 3 element drum level control, and so on.

We're also going to try out GE Energy's online 48 hour CT fundamentals course, along with their on line generator and steam turbine fundamentals. The cost for this package is about $700 if taken over 6 months and about $500 if taken over 3 months. Considering the cost of on site training for one week, this is a real bargain, and it's probably pretty good. We'll find out and let you folks know. They also offer more advanced on line training courses.

I haven't seen anything on line regarding Mark V training, though. My company had a seven day class on site years ago on Mark V w/I stations which was before my time and from what I've seen of the student manual it was pretty thorough and it has proven useful to me as a self-study guide.

No matter what training is made available, however, you can never really know your machines without the site specific documentaion. We have two two-CT-on-1-ST CC units, or four 7FA's total. Each CT pair uses a shared LCI for starting via the EX2000 exiters. These units are not only unique compared to 7FA's on other sites, there are differences between units on the same site even though they were built at roughly the same time.

Part of that is due to control wiring inconsistencies and outright errors, and the rest is due to equipment differences which only GE can explain. For example, the LVDT's on unit 1's GCVs are different than unit 2's. So when we bought spares, we based the purchase on unit 1.

The CSP's are probably identical but after years of operation we're finding problems with the CSP and Mark V configuration, such as missing inputs that "should have been there." The erection engineer wasn't very thorough, as it turns out.

To really know your CT's is going to take a long term commitment and a lot study. I think it's worth it, though, as people with that kind of knowledge are pretty scarce, making them valuable to many organizations.
