LM6000, LMS100 vs Rolls Royce Trent 60

[RobsVette]

Hi Guys,

I recently went to tour a simple cycle gas turbine plant that utilized at Rolls Royce Trent 60 gas turbine engine. It seems to be a very nice and compact package.

I was wondering if anyone has a specific experience with the Trent 60 and can share some comparisons as to the standard GE engines. I have experience on LM6000s and Pratt and Whitney engines, but have never worked on a Rolls Royce engine before.

It seems like it has a higher power capacity with a better heat rate, but it also seems to take 2x the demin water injection as the GE units. They also told me it has a direct drive to the generator so no gear box and maintenance. I also heard that the gas pressure is in excess of 900 psi into the engine (which seems high to me)

Overall it seemed like a pretty nice package and I was wondering what experience you guys have had with these engines and if there are any other major differences between this enginer and the GE engine.

Thanks,
Rob

I think if you compare different GT manufacturers, you should consider comparing equivalent power range within the same application, i.e. power generation or mechanical drive. I guess you are considering here a Power generation.

I would not compare Trent60 to LM6000 as (reading from the brochure on RR website) as there is not negligible gap in power capacity ISO rated. Not even sure it has an Aero derivative equivalent for this power range in the market.

I would include Pros and cons including Heavy Duty / Industrial GT as well of you may consider those for your application.
