Low pressure steamdrum

Standing at an altitude of 47 meters: the low pressure steamdrum of unit EC3.
A gauge glass to check the level is fitted because it's compulsorily (don't know it's the right word) but it's according to the regulations of the steam vessel inspectorate (now Lloyds).
Normally we check the level in the control room, transmitters make that easy.
The pinping on top is the outlet of the steam going to the superheater.
The pipes at the side are coming back from the evaporator, inside is a mixture of water and steam.
Inside the drum cyclones separate water and steam; the steam is going to the superheater, a circulatingpump brings the water back to the evaporator.
As it's the low pressure drum, the pressure in here is low, about 5 bar.
