The scavenge air box is continuously drained
through ‘AV’ to a small pressurised drain tank,
from where the sludge is led to the sludge tank.
Steam can be applied through ‘BV’, if required, to
facilitate the draining. See Fig. 4.06.0.
The continuous drain from the scavenge air box
must not be directly connected to the sludge tank
owing to the scavenge air pressure. The pres-
surised drain tank must be designed to withstand
full scavenge air pressure and, if steam is applied,
to withstand the steam pressure available.

Drain from water mist catcher
The drain line for the air cooler system is, during
running, used as a permanent drain from the air
cooler water mist catcher. The water is led through
an orice to prevent major losses of scavenge air.
The system is equipped with a drain box with a
level switch, indicating any excessive water level.
The system delivered with and tted on the engine
is shown in Fig. 4.03.02 Scavenge air space,
drain pipes.
