Side draft chimney in a smithy that is open on three sides

Recommended Posts

Greetings,

I have been lurking on this site for several months and am hoping for some solid advice.

I am considering building a small smithy in my back yard which will be essentially a shed (for tools) and a large extended roof for my smithy.

I currently have a propane forge but want to build a coal or coke forge.

I am wondering though, will a side-draft chimney that is open on 3 sides, still draw when used in essentially an open environment.

Thanks

A side draft opening is placed very close to the fire pot so it will draw the smoke up the chimney. Having 3 sides open will make sure there is plenty of make up or replacement air, for the smoke and air being sent up the chimney.

 

I have used a side draft with no walls and no roof and it does a good job of keeping the smoke out of the work area.

The only complication you will have is if there is a wind. No different than with the Propane Forge.

Maybe have some moveable or removable side curtains.

I use a side draft at my shows. I put on wind screens/side shields to block the wind as needed. They're on hinges and can be pulled around to make a almost enclosed fire or swung back if not needed.

Thanks for all the responses, your advice is truly appreciated.

Samcro and MTforge: thanks for the pictures. Both are very nice.

I especially like the side shields, MTforge.

Do either of those have smoke shelves in the chimney?

Thanks again

The key to this type of hood is to have a large diameter pipe and enough length to get a good draw.  I always burn some newspaper in the base of the pipe while I start the coal forge going.  It helps to warm the air in the pipe and start the draft.
