What's so amazing is that no vandals have been here.
It's great!
What's the secret of keeping vandals out?
Keep the place live? Touch the wrong thing and your BBQ.
Interesting to see where the meters were. Looks like loads of meters have been removed. Spare parts used in other stations? Yes, power is usualy keeped connected to moth balled power stations. One diesel power station comes to mind that was built around early 1900's. It was moth balled in the 40's and only a few years ago was disconnected from the grid. It has 2 large slow speed 6 cyl diesels that were made in England. About 100 years old now. They still work. Started up now and then for shows.
Motor generators. Or if your from UK motor dynamos. AC motors driving DC generators, made in the days before they had decent rectifiers. Used where ever DC power is required. Unlikely used for exciter power but some one might have designed it that way. Power to drive the rotor coils on large or medium generators are powered from exciters on the same shaft as the generator, mostly. Shows the age if this power station. Should be preserved.
I'm with Gratefulzenz and CS. It's the top of a condenser, the turbine has been removed.
But to split hairs, looks like the steam passes through the tubes and the cooling water surrounds the tubes. Looks cool. Does look like a TV dinner tray.
Sorry Kevlar but it's a condenser as most people here have stated and it's not normally under pressure.
There is a slight vacuum (not accurate term), slightly less pressure than atmosphere pressure at sea level.
It's like the steam is almost sucked from the turbines Low Pressure final stages.
It's a closed loop system. Most nuclear power stations use the same system today, only the difference is a nuclear reactor boils the water, though there are different ways to make steam from nuclear reactors. And as already stated the water from the condenser is pumped back into the boilers in another part of the building to be converted back into steam to feed the turbine.
Because there are conceptual similarities between electric capacitors and heat exchangers used to condense steam to water, not actual similarities hence the change in name.
It's great!
