Is there somewhere to verify if a turbine is proven technology?

[jejaram]

Hi

I understand that the criteria to consider a relatively new combustion turbine as proven may differ from a manufacturer to another, but I guess there should be at least some minimum requirements, so is there a list somewhere where you can check if a specific CT is considered as proven?

Thanks in advance.

Wrong forum; try Heat Transfer & Thermodynamics Engineering or Energy Engineering General Discussion - NOT both

Yes, a combustion turbine (CT), is a mature and proven technology. Some of the modern CT for power plan applications migrated from aero derivatives turbine technology. Check within the mechanical or power generation forums to see if it can provide more technical details as suggested above.

It is interesting to know that In the USA today, combustion gas-fired power plants constitute the majority of all generating with a total capacity of over 40% and growing above coal, nuclear, hydro, and other sources of electric energy.

The first gas turbine for power generation on record was developed by BBC (Brown Boveri Company)in 1939 one of the subsidiaries of ABB sold to Alstom and now GE. After being in service for more than 60 years, the first CT is on display in the ASME Historic Mechanical Engineering Landmark in Birr, Switzerland.

Hope this help

I think the OP's question was more whether a particular model of turbine can be considered mature yet. I wonder if somebody offered them a job lot of WR21s?

Okay, I'll bite: are WR21's immature? [ I see an internet search in my future... ]

Not sure If the Rolls-Royce WR-21 CT can be considered as a new design. Around a decade ago, a major design flaw was discovered since the unit fail to operate in cold temperature. By this time, probably the design issues was corrected.

??? Rolls-Royce WR-21 CT ???
Why are you guys talking this specific one? The OP didn't mention it did he?


Don't they typically reclaim the exhaust heat > steam > and run it thru a stream turbine to scrabble up another 40%?

The OP wanted information about a specific one and failed to say which specific one, suggesting instead that there is a list somewhere of all such devices that an observer could just look at for the one they needed to know about.

It raises the question of who would have the time, money, and access to internal documentation and failure reports to make such a list and why anyone would think such a list could therefore be compiled.

Oh. Okay, thanks Dave. That about sums up exactly what I was seeing. I wasn't missing something. Thanks.

No, but it's not a bad place to start the discussion over whether age guarantees maturity. I suspect the total installed population is still twelve.

Other than that - what Dave said.

This is an interesting question, not only for turbines but for any other equipment aswell.

What are indeed the MINIMUM requirements to verify a proven design, objectively?

I can only think of two:

- A design review, which I guess in turbines world may not be a usual thing.
- Successful factory and site testing. Best would be in an independent lab, but again, I might be asking for too much.

Everything else: years in service, number of units sold/in service, customer reference lists... I think are more subjective and depends from one customer to the other where to draw the line.

Hi,

Somehow I never got notified there were answers to my questiion so please excuse me for not getting back earlier.

The idea of my question was a general list of proven technology. It existed in my previous company and there's only a small one on my current company.

The idea of this question is in general because I find many models of turbines as i survey generation plants for insurance purposes.

I'll ask the specific forum that eluded me the first time.
