12" to 14" diameter should be fine for the 25' to 30' of
stack mentioned by the OP.

That'll work, of course, but it's a bit Mickey Mouse. 8-) I visited a
guy in western Mass., circa 1968, who had the remains of a smallish,
old Victorian, brick-built factory on his property.  He put his forge
*in* the flue.  There was a 40- to 60-foot brick smoke stack with an
iron door at ground level, maybe 8 or 10 feet in inside diameter.  Put
the forge in there, open the door and the draft was stupendous even
without lighting a fire.  IIRC, in practice he had to just prop the
door open a crack so the breeze wouldn't suck anything less dense than
iron up the and away.

       Powerful enough to suck prairie dogs from their holes, but
       gentle all the same....  --  Tom Parmenter, "Desperado"

Baddest forge flue I ever saw.  Envy. :-)
