Other exhaust design criteria are as follows:
A flexible connection between the exhaust
manifold and the piping system should be used
to prevent transmission of engine vibration to
the piping and the building and to allow for
thermal expansion and any slight misalignment
of the piping. (See Figure 4.4)
The exhaust gas pipes should be supported by
the building in order to prevent the dead weight
carried by the engine manifold
and turbocharger. For that, stretching,
elements should be used. (See Figure 4.5)
Exhaust system components located within the
generator room should be insulated to
reduce heat radiation and noise levels. Pipes and
the silencer, whether located inside and outside
the building, should be located well clear of any
combustible material.
The outer end of the exhaust pipe, if horizontal,
should be cut at 60° to the horizontal or should
be fitted with a rain hood or cap, if vertical, to
prevent rain or snow from entering the exhaust
system.
The exhaust pipe must not be connected to
exhausts from other generating sets.
Exhaust pipes must be made up of black iron
pipe.
