Combined cycle 22 MW plant

Combined cycle 22 MW plant

Combined cycle 22 MW plant

(OP)
Hi,

I am trying to get a ballpark numbers for a 22 MW combined cycle plant (gas turbine + steam turbine
Can somebody help me out with the list of equipment needed and ballpark prices?

Thank you very much for your help

RE: Combined cycle 22 MW plant

ramdass....

A Combined Cycle plant of 22MWe is a little on the small side. Remember, the steam turbine will require many auxiliary systems (water, chemicals, lube oil etc) and the unit cost for each additional steam turbine MWe becomes high on a unit that small

You would be well served to contact the major Gas turbine vendors (GE, SIEMENS etc) as well as the used equipment market to see what was available.

Consider for small gas turbines the venerable GE LM2500..... about 22 MWe at ISO conditions.... about 6-9 million USD (used)
(Perhaps the finest gas turbine ever designed)

Of course you must consider plant emissions, siting, fire protection, noise, switchgear etc....

Is this truly a "combined cycle" installation you are interested in or perhaps, a "cogeneration" configuration ????

Thanks for the info. It is a combined cycle, the customer doesnt has any use for the thermic energy, so cogen is no use.

Is there another technology to raise the efficiency of the systm instead of the steam turbine?

Thanks a lot

RE: Combined cycle 22 MW plant

No..... this is the best that can be done.

If there were a way to improve upon this combination of thermodynamic cycles, the inventor would be a very, very rich man
