[TheForge] preheating forge blower air

[Daniel Crowther]

I've often wondered about this as well.

         Or does it actually work against the combustion process because 
hot air is less dense.  Dodge experimented with Intercooled aspirated car 
engines on the principal that colder air is denser and will give more 
oxygen for the same volume.  The HP did increase, so it worked for them.
         Is there something else going on that makes preheating for forge 
combustion good and bad for auto combustion?
