Looking up!

To the top of the turbine hall of unit EC 20.
Plenty pipes, leading to and from the feedwatertank which is at a platform in the top of the turbine hall.
The five pipes in the middle are coming from and going to the feedwaterpumps of the exhaust gas boiler of the old small gasturbine. Not in service anymore.
The two bigger pipes which disappear into the floor are used to heat up the feedwater in the tank by means of steam.
The square duct at the left is for ventilation of a part of the turbine hall.

Here in LARGE....
