[TheForge] flue pipe temperatures

[Bruce Freeman]

I take it this is an overhead hood, not a side-draft hood? 

If so, try this and save yourself some trouble.  Add a removable extension pipe down closer to your fire - maybe 6 to 8 inches above the fire.  Now, if your flue is at all decent, you should get the draw you need without the inducer.  

Of course, you need a tall enough flue, especially if you have any elbows in it.  Without elbows, a 12' flue is plenty.  There's some rule of thumb about how much extra you need per elbow, but I don't remember it.

A flue is one of the simplest "engines" around.  It only makes sense to take full advantage of it.

       Would anyone have a guesstimate as to the temperature in an 8 inch 
flue pipe coming from a smoke hood  mounted 16 inches directly above the 
fire during a forge welding session?Why the hel?? would anyone care you 
say?I dont have quite enough draft and rather than installing a bigger pipe 
i picked  up a used draft inducer fan which recommends no more than 600 
degrees F.
