[TheForge] preheating forge blower air

[Stephen McGehee]

Yes, that has been thought about a lot.  In "plain and ornamental =
forging" by shwartzkof(sp?), he shows a cut of "The Lindwurm =
Recuperative Forge" and claims to be able to take 2" round to a forging =
heat in 2 min.  I attempted to do a patent search with what little info =
was in that book, but  the cumbersome search machine at the patent =
office web site and my own ineptness did not find anything.   With all =
the recuperative appliances the idea is that the hotter the combustion =
air, the hotter and more efficient the fuel conversion is.
Dimitry Gerakaris uses hollow soapstone chambers around his flue to =
preheat frigid New Hampshire air for injection to his fire, not to get a =
hotter fire, but to keep 0 degree air from cooling the fire =
unnecessarily.  I want to build a recuperative firepot myself, have =
several pages of sketches already.  Please keep me in mind when you work =
yours up.
