[TheForge] flue pipe temperatures

[TOOL GYPSY]

Wise sages
       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.
