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. 14.06.01.
The continuous drain from the scavenge air box
must not be directly connected to the sludge tank
owing to the scavenge air pressure.
Fig. 14.06.01: Scavenge air box drain system
The pressurised drain tank must be designed to
withstand full scavenge air pressure and, if steam
is applied, to withstand the steam pressure avail-
able.
The system delivered with and fitted on the engine
is shown in Fig. 14.03.02 Scavenge air space,
drain pipes.
