Corten Is Fracturing in Natural Gas Burner
Corten Is Fracturing in Natural Gas Burner
(OP)
I am a project engineer in a paper mill. During an outage this week, discovered a failure of a 10ga corten duct downstream of a natural gas burner that is used to heat air used in the drying process. I have never seen anything like this, and will liley send out samples for analysis.
Anyone care to comment on what might be causing this? The metal is highly fractured and can be broken off by hitting it with a hammer. Area in question is at the top of an internal screen. Temperature around 900F

I also observed surface deposits that are fissuring as a result of this same penentration locally flexing the ductwork. Check flow conditions and use thermography after repairs.

And, where is the 900F? In the burner, the duct, or at the point of the failure?
I don't know if it holds true for Corten per se, but remember that for carbon steel, 900F is starting to glow dull red. Would that have been observable from the exterior?

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor
