Installing Condenser Parallel or Downard to Steam Turbine

What exactly do you mean by, "Installing condenser parallel ... to Steam turbine?

Normal place for the condenser is down stream of steam waste heat exchanger, if used, after the last stage of turbine.

They are in series, not parallel. Boiler→turbine→condenser (and usually return to boiler to form a closed cycle).

Let me try to parse through the broken English that is the hallmark of this website.

In many newer Combined Cycle plants, smaller steam turbines can be configured with the steam surface condenser ALONGSIDE (at the same elevation). I believ that this is what the OP meant when he said parallel

The advantage of this configuration is that plant capital costs are reduced with a shorter building. The disadvantage of this configuration is an increased pressure drop between the turbine and condenser.

The older configuration has the condenser located directly below the steam turbine. The steam turbine must be elevated somewhat This, of course, requires a substantial concrete/steel structure.

Large central steam stations cannot utilize the ALONGSIDE configuration.

I am sorry to confuse you guys. "Parallel" I meant is installing condenser alongside at the same elevation with Steam Turbine in Combined cycle plant.

Previously I thought that this configuration made more pressure drop between Steam turbine and Condenser than when we install condenser below Steam turbine, but the vendor says the pressure drop is the same between two cases, so I wish to know what is correct.

Dear Mr.Philipwon,

The Title and your statement

"Could anyone please let me know what is better in the Steam turbine performance aspects and what are general pros and cons between two cases?Could anyone please let me know what is better in the Steam turbine performance aspects and what are general pros and cons between two cases?" does NOT match.

What I understand from the topic - is WHETHER THE CONDENSER TO BE INSTALLED DOWN BELOW THE TURBINE or MOUNT AT THE SAME LEVEL, BY THE SIDE OF THE TURBINE.? If so, the civil work in terms of Foundations and Elevations, and hence Building Height alone will be less for side installed condenser, suitably the Turbine Steam Exit will be decided. Performance wise , it should NOT matter.

...as any water droplets appearing towards the aftermost stage of the turbine will tend to escape from it under the influence of gravity.
