I'm considering building a forge next to my wood stove and building a Y-pipe to use the same stove pipe out of the shop. I'm not sure if this will work. Has anyone seen or heard of this being done? Any thoughts, opinions, or recommendations would be greatly appreciated.

Thanks,

I think I'd avoid headaches and just put in another stack, I don't know of any codes that allow more than one unit on a stack. Wood and coal are two very different fuels to exhaust. I'm no expert though.

I wonder if you would have the capacity for both?  Your shop stove pipe probably was built to handle the volume of smoke from the stove.  Adding more from the forge might or might not give you the necessary draw.  Then again, the stove's pipe upward draw might pull your forge better...dunno...food for thought.

 

Stove experts out there???

That was my original thought.  That the stove draw would benefit.  I don't know how I would test it without just doing it.

 

Arkie,  I noticed you are from NWA.  Where about?

Twice the open area should cut the draw by about 1/2.

Look at pictures of a side sucker system bending the flames horizontally and explain why it needs the extra help?

No, the smoke from the stove will fill the stack's carrying capacity. Both will draw worse, not better.

You make a good point. Haven't really thought of that way.

A forge is an open hearth, or in other words a type of fireplace. A wood stove is a different kind of heating appliance a fire place draws a lot of air to insure the smoke makes it up the flue, wile the stove, being enclosed draws less air.

Are you talking about installing a coal forge?  You might want to consider that the chimey on a woodstove works a little different than one for a coal forge.  Generally, a woodstove uses a 6"- 8" flue pipe, whereas a coal forge works best with a 10"-12"+ chimney.  You'll likely find that the smaller pipe from the woodstove is inadequate for drawing the exhaust from a coal forge.  Also, most building/fire codes that I have encountered don't  permit sharing a flue pipe between 2 systems.

Yes I'm building a coal forge and it is a 6" stove pipe on the wood stove.  I am a little concerned about the capacity of the pipe.  I live in the country and it's my personal shop I don't think code violation will be an issue.

Is your building insured? If so and you put in a non-code installation they will probably refuse to pay on it if *anything* happens. I was born in Fedvill, graduated from the UofA and married there; still drive through from time to time...lots of kin folk in NW AR; got a stepdaughter and twin grandkids in West Fork...

Really better if you just back up and build a 12" pipe for your forge, dont plumb in your wood stove as it will still mess things up. You may consider a damper and make up air if you live in cold contry. Make up air is never a bad idea for a woodstove either, better to pull in temperd air from a controled sorce than cold air from anywar it can find a way in.

Thanks guys for all the advice.  Thomas if you get back to the area let me know we'll go grab a burger or something.  Better yet if I have all this built by then you can come over and show me a thing or two. :)  I know I'll need all the help I can get.

Well guys I am very happy to say IT WORKED!!! I cheated just a little but I'm ok with that. I hook up an air line to help create a vacuum. It takes about 3-5 minutes for the flu to get hot and once it does I can shut the air off and it drafts GREAT.
