1500? Benson"bottle" at EC 20

In HDR.
Part of the boiler of unit EC 20.
One of the so-called "Benson-bottles".
You can see it as a vertical steamdrum.
Originally there were three of these, during the tranfer to a combi unit two more were fitted to increase the water capacity.

And: I saw I reached nr 1500....
Last nightshift; will be here again on wednesday.

Here in LARGE...

Here is some more info about Benson boilers, now mostly used as supercritical boilers.
At EC20 it was used as a subcritical boiler with circulationsystem at max 180 bar.
