Emission limits
In general the engine is designed to fulfil the
emission limits according Worldbank II
(2007/2008) for plants ≤ 300 MWth and non-
degraded airshed.
SO
x
and PM emissions are mainly influenced by the
fuel specification. The sulphur and the ash content
must be limited accordingly. The NO
x
emission is
influenced by the ambient conditions, fuel specifica-
tions and operating conditions of the engine.
Please contact MAN Diesel & Turbo at an early
stage for project specific emission calculations
(contact your sales representative).
Needed adaptions of the engine parameters to fulfil
project specific emission limits may in minor extent
affect the fuel oil consumption.
