January 21, 201412 yr 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 JB
January 21, 201412 yr 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.
January 21, 201412 yr 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. Neil
January 21, 201412 yr 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.
January 24, 201412 yr Author 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 JB
January 26, 201412 yr 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.
