Für Auftragschweißaufgaben existiert eine Vielzahl an verfahrenstechnischen
Prozessvarianten, die je nach Charakteristik und Anwendungsfall
ausgewählt werden. Ein Nachteil der vorwiegend verwendeten Metall-
Schutzgasschweißprozesse (MSG) für das Auftragschweißen ist durch die
direkte Kopplung von Drahtvorschub zu Energieeintrag gegeben. Die vorgestellte
Zweidraht-Prozessvariante kann durch die Ausbildung eines übertragenen
und eines nicht-übertragenen Lichtbogens die elektrische Leistung
beider Lichtbögen variieren und damit einen direkten Einfluss auf
die Prozessgrößen Abschmelzleistung und Aufschmelzgrad nehmen. Im
Speziellen besteht über die Entkopplung von Drahtvorschub zu Schweißstromstärke
die Möglichkeit eines niederenergetischen Betriebs trotz hoher
Drahtvorschubgeschwindigkeit. Damit lassen sich Aufschmelzgrade
unter 2% umsetzen und Abschmelzleistungen bis zu 15 kg/h realisieren.
Combined with the use of renewable energy sources for
its production, Hydrogen represents a possible alternative gas
turbine fuel for future low emission power generation. Due to
its different physical properties compared to other fuels such
as natural gas, well established gas turbine combustion
systems cannot be directly applied for Dry Low NOx (DLN)
Hydrogen combustion. This makes the development of new
combustion technologies an essential and challenging task
for the future of hydrogen fueled gas turbines.
The newly developed and successfully tested “DLN
Micromix” combustion technology offers a great potential to
burn hydrogen in gas turbines at very low NOx emissions.
Aiming to further develop an existing burner design in terms
of increased energy density, a redesign is required in order to
stabilise the flames at higher mass flows and to maintain low
emission levels.
For this purpose, a systematic design exploration has
been carried out with the support of CFD and optimisation
tools to identify the interactions of geometrical and design
parameters on the combustor performance. Aerodynamic
effects as well as flame and emission formation are observed
and understood time- and cost-efficiently. Correlations
between single geometric values, the pressure drop of the
burner and NOx production have been identified as a result.
This numeric methodology helps to reduce the effort of
manufacturing and testing to few designs for single
validation campaigns, in order to confirm the flame stability
and NOx emissions in a wider operating condition field.
