Position of gas outlet on turbocharger
B 16 02 0 shows turning alternatives positions of the
exhaust gas outlet. Before dispatch of the engine
from Holeby exhaust gas outlet will be turned to the
wanted position.
The turbocharger is, as standard, mounted in the
front end.
Exhaust gas boiler
To utilize the thermal energy from the exhaust, an
exhaust gas boiler producing steam or hot water can
be installed.
Each engine should have a separate exhaust gas
boiler or, alternatively, a common boiler with separa-
te gas ducts. Concerning exhaust gas quantities and
temperature, see list of capacities D 10 05 0, and
engine performance D 10 10 0.
The discharge temperature from the exhaust gas
boiler should not be lower than 180° C (in order to
avoid sulphuric acid formation in the funnel).
The exhaust gas boilers should be installed with by-
pass entering in function at low load operation.
The back-pressure over the boiler must be consid-
ered.
Expansion bellow
The expansion bellow, which is supplied separately,
must be mounted directly on the exhaust gas outlet,
see also E 16 01 1-2.
Exhaust silencer
The position of the silencer in the exhaust gas piping
is not decisive for the silencing effect. It would be
useful, however, to fit the silencer as high as
possible to reduce fouling. The necessary silencing
depends on the loudness of the exhaust sound and
the discharge from the gas outlet to the bridge wing.
The exhaust silencer, see E 16 04 2-3-5-6 is supplied
loose with counterflange, gaskets and bolts.
