The additional power output from the TCS-PTG system is in the
form of
50 or 60 Hz electrical energy for the onboard power grid. The
power turbine
is inserted into the exhaust gas system parallel to the
turbocharger. It drives
an electrical generator via a reduction gearbox and receives up
to 13% of
the exhaust gas flow, diverted from the main engine exhaust gas
receiver.
With this TCS-PTG stand alone solution in operation, auxiliary
engine fuel
and maintenance costs can be saved, CO2emissions reduced and
gener-
ator set maintenance more flexibly planned and carried out with
the ship
underway!
Used in combination with MAN Diesel high efficiency
turbo-chargers on themain engine, and depending on fuel oil prices,
payback periods as short as
3 to 5 years can be achieved.
The TCS-PTG system is recommended for engines with rated
outputs
above 20 MW and in marine applications where the onboard
electrical load
is in excess of 10% of main engine power.
