water and steam flow diagram
Blue: the downcomers lead the water from the steam drum to
the water drum and the waterwalls headers.
Red and blue: the evaporation tubes and the water walls lead
the water and steam emulsion back to the steam drum.
Red: the steam passes through the superheater before it leaves
the boiler for the consumers.
One large V2M8 boiler is installed in a ship at a shipyard and
another marine boiler is still suspended in the crane-hook.
When the marine boilers are placed and secured then the engine room will be
built around them.
The hole in the floor just astern of the marine boilers will be the place
for the propulsion steam turbine.
