Exhaust system

Dry exhaust line

The figure shows an example of how a dry exhaust
line can be installed. The line should preferably be
made of acid-proof stainless steel pipe, but a satisfac-
tory service life can also be obtained with other stain-
less steel pipe. Copper pipes must not be used for
diesel engines. Due to the high temperatures, 400°C–
500°C (842°F–932°F) occurring in the dry exhaust line
it must be insulated with insulating material this to
avoid the risk of fire and personal injury.

The line must also be provided with a flexible compen-
sator (1) to absorb heat expansion and vibration from
the engine. The compensator is fitted on the engine
exhaust pipe flange as straight and stress-relieved as
possible.

The exhaust line must be insulated throughout its
whole length, noting that the movements of the com-
pensator must not be obstructed. After the compensa-
tor, the exhaust line, including silencer (4), must be
suspended by flexible brackets (2, 3) so that the
movements caused by heat expansion are not ob-
structed.

The exhaust fitting is placed in a suitable position with
good margin of clearance above the water-line with
loaded boat and with insulation against the hull side to
prevent heat damage.

An arrangement for draining condensation water
should be fitted at the lowest point of the line.

When dimensioning the exhaust line, note that the
back pressure in the complete exhaust system must
not exceed the values shown in table on page 78.
