Turbine Burner Alloy? 1

[KatyDave]

I am intrested in making a burner for turbine. Is there an alloy that has a higher intermittent operating temperature tha 310 stainless?

Both 330 and outukumpu 353MA should give better performance.

What kind of burner and for what type of turbine? Are you are referring to a burner that is used on small industrial turbines to generate electricity? Proper selection of the burner material depends on fuel and operating conditions. For the more advanced combustion turbine (CT) applications, Haynes International and Rolled Alloys provide a range of heat resistant (HR) alloys for components. Your alloy selection will depend on combustion turbine design and fuel;

Thanks for the info! I just discovered "eng-tips" and it is great, I am sure it will save lots of research time. I am a home build aviator interested in building a small turboprop engine (~ 50 kW). The fuel will be jet fuel/diesel and I plan on modulating the air flow to a maximum temperature. I see the HAYNES 230 alloy has an operating temperature to 1200C, I can't find info on the 330 & 353MA. 1200C should be good however, thanks....

The rolled alloys site has extensive information on all these alloys. Download the pdf.'s.

Hastelloy X is the old standby, it should handle 1125-1150C. 230 is a step up from there and 214 is the top of the heap. The trick with burners is that they are not operating at the flame temp, they are actually cooled by the fuel.

Corrosion never sleeps, but it can be managed.
