The use of DLN turbines has very positive points. The DLN
turbines are modern machines which have a higher efficiency
than older machines. This together with the fact that they will
be more heavily loaded than the non-DLN turbine results in a
reduction of CO2 emissions for the same total output power.
The NOx emissions are thus greatly reduced, typically by a
factor of 10 or more, and this is very important today since
more and more regulations are coming into force on this
subject. The opportunity to integrate power with exhaust heat
recovery systems also increases overall fuel efficiency by
approximately 30%, with a corresponding reduction in energy
consumption and emission of CO2. These efficient modes of
operation however, are based on global secondary regulation.
