Maverick, the gaps between the different stages are there for a reason. The video shows the rotor with the top casing removed. In between each stage set a diaphragm which houses stationary vane in the opposite direction that the turbine blades and buckets are positioned to optimize air flow. Also all the blades on the rotor turn at the same speed from the front (compression side) all the way to the rear (combustion side). It is a gas turbine and not a steam turbine as well.
And on the same side, lol, that tends to reduce the compressor performances for each further stage, as the air tends to rather rotate with the blades than follow a linear flow!
It should at least have some stationary blades inbetween the rotor ones, if it's not possible to have conter-rotating blades which radically increase performances...!
It is built up. Each rotor disc is engaged to the next one by Hurth serations. The whole lot is clamed together by a single tie rod through the centre, pretensioned with a huge nut on the end. Sounds really primative, but it certainly isn't. The standard of engineering on these gas turbines is world class. I operate one of these awsome beasts in a power station. 6 minutes from barring speed to 3000rpm and synchronised to the grid. The sound makes your spine chill.
nee, dat ding levert stroom, ze jagen er oververhitte stoom doorheen door water te verhitten, heel snel en dan gaat de turbine draaien, zetten ze er een generator achter en die levert de stroom... das het basisprincipe van een elektriciteitscentrale
More than likely going to remove the rotor. I have seen so much garbage around turbine and compressor rotors while on turning gear. It is plain to see the FME on this turbine deck is non-existent. They are most likely checking something else in the train and the guy is just there as a look out while on turning gear.
Ha! Tung Hsaio. I worked on the old frame 5 GE's next door in 1980 when Mt. St. Helens blew up. They were ancient then. The Frame 7's and the Brown Boveri single combustor units were just being built.
as far as I know the stators are in the housing of the turbine/compressor itself. so the rotor blades looking out and the stator blades looking into the engine.
This machine is on the half shell. The upper stator blades came off with the shells. You can see 3 stator blades on the lower right in the lower half of the housing. The 14 stage compressor is on the right and the 4 stage turbine is on the left. At 19 sec I see the #1 and thrust bearing OPENED! Scarey! The lower half of the thrust brng can roll out and that rotor can peel out some stator blades before you shut off the turning gear. The tarp is way too close to the 4th turbine stage for me!
Woops, 16 stage compressor, maybe more. Hard to see... Some GE's I worked on had 17 stage compressor and 3 stage turbine on a single shaft like this unit. Check out the guy by the ladder next to the exhaust at 0:06 to get some idea of the size. My guess, this is 50 cycle generator drive, 3000 rpm, 482,000 horsepower at rated load. I used to overhaul stuff like this and now I feed squirrels and window peep for excitement. This brings back so many memories....
You are quite right kimmer6, it is a 50 cycle unit designed and used for power generation. 265MW in open cycle (simple) operation, but generally used in combined cycle plants where the exhaust gases are used to generate steam in a heat recovery boiler and thus power a steam turbine. Typical combined output for a combined cycle installation using a V94.3a2 is 390MW and a thermal efficiency of circa 60%.
is this a W501F?

It's not to stretch it it's to get the slight sag out of the shaft that developes when it's stationary

Is this Gas Turbine or Steam turbine?

Looks like steam to me because of the lower frame. i have never seen a gas turbine that comes apart in two halves like that.
Also, if its a gas turbine where is all the fuel hydraulics and electrical spaghetti on that lower half?

Not something you see everyday! Why was it cranking though? I can see the bearing keeps are fitted but why the need for turning.
ferretflasher 3 years ago
I hardly think so....more likely to bed the lab seals in and allow them to cut new grooves if they have had new bearings etc fitted.
I doubt SIEMENS would tolerate ANY materials in the disc or blade areas, just far too expensive to risk me thinks!!!
