Gas Turbine, Generator rewinding

Hsd ( high sulfer diesel) leaves a carbon build up behind till you reach tot in normal range. I'm assuming your tot is around 750f or 850f?

Where ng leaves nothing behind no residue.

 

That's why your (hot section) looks nice and clean ng only very smart they are.

 

Pretty cool thread i also work with combustion turbines,hrsgs steam turbines etc. For a big utility company in Az. @ColoradoTJ already knew that tho! We just had a big uh oh at my plant yesterday. We have 3 units thats are comb. Turbine generator and steam turbine all on the same shaft. They have little hrsgs on them. Supposedly only 11 left in the world and we have 3 of them. Anyway the gas turbine side uses Fryquel (hydraulic fluid) while the steam turbine has its own lube oil system which runs a turbine oil 32.. well we were just about done with this outage when we realized we have an oil leak. Come to find out one of the fryquel line runs inside of a larger pipe which also has a steam turbine lube oil line running thru it. For those of you whom dont know they double wall the pipes so that in the event of an leak it would be contained and drain back to the oil sump or tank. Well that particular fryquel line never got tested because the limit switch which tells the turbine conttrol valves to dump the control oil in the event of an trip had been held in the tripped position. One of our fine operators found this and reset it as it should be. Well that fryquel line had a leak and not just a little one it dumped almost 400 gallons of fryquel into our steam turbine lube oil sump and overflowed it luckily it has a nice big containment. So now i am sitting here pumping oil with sump pumps so we can identify the leak and make repairs. Also the steam turbine lube oil is now trash we are talking about 1500 gallons of oil maybe more. Plus we had to refill the gas turbine side with fryquel which is a cool $51.00 a gallon!!

 

Thats pretty jacked. Look at the bright side, at least you'll run again. I remember back in my submarine days, I had to dive full oil bildges and clean that out by hand and a wetvac. Also, a couple of our sister plants have "corn cobbed" their turbines, and another sister plant out by Boron had it's A & B cells of their cooling tower completely collapse while there were contractors running out, which was the final straw to just shut down the entire plant. Luckily you had secondary containment, if our LO sumps overflowed it would go straight into the rocks/dirt which would be an environmental nightmare.

 

Ha ha this outage was supposed to be over dang it ha ha. But like mentioned above at least they are fixing it all. Our big 2x1 should be good to go some time nest week. That unit had a crack in the main steam stop valve housing kinda scary they are fixing it up but one area ill be steering clear of ha ha!

 

We had an LTSA for about 10 years then dumped them. Very expensive and GE parts are very expensive, for example our R0 blades were quoted by GE to be I want to say over 2 mill, and Alstom jumped in and offered an aftermarket set compatible with the GE 7FA's for like 700k. We took the Alstom ones and haven't had any problems. Ironically, however, I'm pretty sure GE owns Alstom now, lol.

 

Lol..

I have been around the orenda gas turbines in banks of 9 each and 8 banks. they where for stand by power.

 

I wasn't allowed to do security reasons. :-( they took our phones and secured them for us. Assholes.

Edit tho I did get to watch a start-up and go-to max power and go full power grid.The ground was moving all I will say.

 

Well we still use GE for tuning on a per job basis amongst other things, but after running the numbers, it was not worth having the LTSA, yes they are convenient, and are a huge help, but not completely necessary from what we've seen. It ended up just being much cheaper to source our own work as needed.

 

We had to borrow some of there land they where cool enough to show few of us around screwed them up when I said wait that's a orenda turbine there mouths went open and showed me everything...lol

My work ugh if I can quit working road I would man. Doing strange stuff all I can say . But I am the boss so. But I'm cool I respect everyone but don't screw up I'm your nightmare.

My printing work is nothing. Made some cool stuff for people with it. But I'm a perfectionist on stuff with the engineering part.

 

And I'm sitting over here building wind turbine blades

 

Welding? Lol the blades are all fiberglass and resin. I'm just a lowly ant on the production floor

 

Yup only the blades in Windsor. The othe components are built throughout CO

 

Nope. There is another blade plant in brighten as well as the Nacell plant there and then the tower plant is in grand junction or pueblo, I forget exactly

 

That's cool as shit. When I worked for SoCal Edison's cal lab, next door to our building was SCE's armature refurb group. Some were from dam generators and from SCE San Onofre nuke plant. Freaking huge. Just like your pics. Freaking amazing.

 

Where I work...Vestas is one of our biggest clients. We recently picked up Windsor facility. Already have been calibrating Brighton and Pueblo units test equipment. Extra paperwork bs for Vestas is a PITA. Great contract tho....

 

Pueblo.
