Possible Prior Art

There may be prior art related to catalyst-coated surfaces in combustion systems for improved fuel combustion efficiency and reduced emissions.

Unanswered Questions

How does the rare earth oxide component contribute to the efficiency of fuel combustion in the gas turbine engine?

The rare earth oxide component in the catalyst particles may play a role in enhancing the chemical reactions during fuel combustion, but the specific mechanisms need further research to be fully understood.

Are there any limitations or drawbacks to using a coated passage wall with catalyst particles in gas turbine engines?

While the coated passage wall may offer benefits in terms of fuel efficiency and emissions reduction, there could be challenges related to the durability and maintenance of the coating over time. Further studies are needed to assess the long-term performance and cost-effectiveness of this technology.

Original Abstract Submitted

A mixer assembly for a gas turbine engine. The mixer assembly includes a housing and a fuel injection port. The housing has a passage formed therein, and the housing includes a passage wall facing the passage. The fuel injection port is fluidly connected to a fuel source and is configured to inject a hydrocarbon fuel into the passage. At least a portion of the passage wall is a coated passage wall. The coated passage wall is (i) coated with a layer of catalyst particles comprising a rare earth oxide component and (ii) located downstream of the fuel injection port.
