[TheForge] blown vs. Venturi forges

[Jerry Frost]

No.

Properly tuned a burner is a burner is a burner. The 
proper ratio for a neutral Air:Propane flame is 17.5:1 
it doesn't make any difference how you put the two 
together and mix them.

A gun (blown) burner is easier to make, tune and are 
less sensitive to back pressure BUT they're more 
expensive and tie you to electric service.

Naturally aspirated burners require more precision to 
make and tune and are more sensitive to back pressure 
and stray breezes BUT are cheaper to make and work 
anywhere.

In either case you're introducing a specific amount of 
propane to a specific amount of air and hopefully 
mixing them thoroughly before they get to the furnace 
chamber. For any specific amount of propane there are a 
specific number of BTUs available. Period.
