Rick can you make any sense of this?

You both have really muddled and overcomplicated the issue.

Condensate depression is simply the difference in temperature between
the temperature at which steam will condense at the pressure existing in
the condenser and the temperature of the condensate in the hotwell.

Too much cooling (beyond about 10* below condensation temperature) means
that BTU's are needlessly tossed overboard and must be replaced by
burning expensive fuel.

All I did was ask the question.

Absolutely & precisely correct.

Yes.... although the Navy cares less than they should about fuel
economy. We used to shoot for 5 degrees.

Here's a fun thought... let's list all the unexpected things found in
main condenser headers. How about a case of beer (unfortunately mangled
& empty)?

It's Dougs fault. He always does this (asking ever more arcane
irrelevant questions) when when he's painted himself into his corner of
ignorance. He goes on and on until he finds something that you can't be
bothered to answer and then he'll jump around the playground claiming he
scored some point. I can see he's trying to do it to you now...
