Paul Bunyan Discada ?

[damascusmaker]

A good friend saw my recent build and was reminded of this piece in his inventory. He's kicking around ideas. Like mounting it to an axel and trailer hitch. It is an old boiler end 4 feet id, 12" deep in the center and heavy. Killer looking piece with all the rivets. 

Suggestions? If he don't build a discada it may end up as a table.

Seems a bit big for a Discada. Going to need a shovel to stir fry in it and custom other tools. Might be useful on a Catering Trailer or on a Ranch feeding 20 guys every day. Kind of Cool though. Would make a nice Fire Pit out on a deck...JJ

I'd lean towards a fire pit or something else that DID NOT come into contact with food.

That looks like a VERY OLD boiler part, and back in the day, they LOVED to use stuff like hexavalent chromium and arsenic based water treatment chemicals...  Those love to bond with metals and they tend to stay for a very very long time.  They also like to be called heavy metals which don't do nice things to one's body...

Man I love Heavy Metal when I'm smoking. I mean come on, listening to Slayer, Metallica, Megadeath, Iron Maiden, AC-DC, Black Sabbath, MotorHead is one good way to stay up during those all night smokes!

Even as a fire pit it may not be the best idea if those heavy metals do exist. His idea to use it as table might be the best idea.

Good point dirtsailor! Down wind could be an issue!

You forgot Nightwish...

Wouldn't the heavy metal be burned away? Seems if they are that volatile there no way they would be there all that long...JJ

Thanks, some good information. I'll pass it on to my friend. He remembers the piece being around his grandfather's house when he was a child, 50s -, 60ish. Doesn't know how long it was on the farm before he came along.

Depends upon how long the alleged metals were in contact, depends on the levels used, and also depends on the amount of heat used to burn out

On this one, I'm gonna be like I am with using galvanized in a hot smoker. Don't do it. Scrap yard metal is scary.

Hey Cranky,

When I think of a steam boiler I picture an engine where the steam is used then wasted to atmosphere. Were there closed systems where chemicals were retained? Were the chemicals used as corrosion retardents?

Even the steam boilers that go to atmosphere will have corrosion inhibitors and microbial inhibitors.  A lot of boilers are closed loop so to speak and provide heat for industrial applications and even provide heat for work space conditioning.  Since that water is continually circulating you have a great potential for scaling inside of the tubes and pipes.  Hexavalent chromium was GREAT in keeping the corrosion down, the problem is that is causes cancer.

Now days, most all corrosion inhibitors in closed loop systems are NITRITE based!
