Just found the attached file on the Net, now I understand what we are talking about. Can you give the part no. for your Torque Converter

Thanks for that, it is a Sprag Clutch, usually part of the Torque converter. You said these were Nuovo Pignone Frame 5 machines, do you know when they were manufactured? You said these machines were from Nuovo Pignone, are these clutches from the original build? What is the starting means...

Lets try again, I know what a jaw clutch is and a torque converter and I know exactly how they work but what is an overrunning clutch?? Do mean the clutch tried to engage when the shaft was turning or what??

Can you explain what you mean by "overruning clutch as the torque converter could not turn" particularly overrunning clutch

Hi Lifa, my answer today would be same as it was when I wrote the above reference. It's called Predictive Maintenance (used to be Preventative Maintenance) in a few words, fixing things before they break down. Firstly look at your plant and see what has been causing you problems, do you perform...

Firstly, I'm afraid the document I sent you is not going to be much good, it is for GE Speedtronic, I don't know what Turboline is, was that an upgrade installed by your company? Your nameplate data is rated at ISO conditions, this is ambient temp=15Deg.C, Humidity = 60%, Altitude= Sea...

I'll leave @AR1969 (or someone from their site) to hopefully contribute. The one thing that no one discussed was the problem with the fuel gas supply pressure fluctuations at their site, if that could be corrected, they would pretty well be able to manage their problem. I don't expect that GE...

Do you have a similar DLN-1 operational problem or are you just curious? The present day answer is don't operate outside of Premix at all if possible or for as short a time as possible. If you haven't seen the state of combustion hardware used in Lean-Lean or Extended Lean-Lean for long periods...

Firstly, I don't know which control system you are using, also you don't seem to understand much about turbine control systems. I'm assuming that you are using a GE Speedtronic MK? and I'm going to attach a Fundamentals document for Speedtronic Controls MKVI, please read first and then comment...

Did you find any answer to you CPD problem ?

I guess it is possible to have a leakage somewhere but, for me, a long shot. if this was a new rotor a year ago I would expect a small drop in CPD , it is pretty much the same as the aging factor on a new rotor. Your drop in CPD is very small, so many things could cause it.I would try an offline...

Has your ambient Temp. changed dramatically? Are you sure you don't need an offline wash? When did you last do one? Can you give previous CPD, Preferably at the same load and give Inlet Temp (CTIF)

Well said

Attached is GE's guidance on cooldown

I'm a happily retired engineer, I don't keep piles of information for old jobs, if I had something that was relevant I would give it to you. I don't think that you understand, the MS5002 was for mechanical drive applications only, people who worked in power generation would never see these...

Attached is DLN 2.6 doc. Sorry, I don't have any Control Spec.

There are many documents on DLN on the GE website, the latest DLN for the MS5002 is 2.6, DLN on the twin shaft it is really no different to the single shaft machine. Control Specs. are completely machine specific by site so I never keep any and to use one for a different machine would just be...

Sorry, I don't have for a MS5002 but I have for a MS3002 an old document. Pretty much most of the systems are the same the 3002 is just smaller (About 9Mw). The document is old from around MKII Speedtronic days but, particularly for Control & Start-up I think it will help you. Take a look first...
