I plan on experimenting with a ribbon burner. I can't wait to see some
pictures, and hear how it works out for you once you get it all worked
out.

I'm planning on trying one in a modified recuperative forge, along with
one or two other burner designs.  I'd like to see how the temperature
changes, so I was thinking of picking up an optical pyrometer from
Ebay... Any one used one, or have any advice on measuring forge
temperatures?

Here is a brief progress report on my work on ribbon burner nozzles.

Yesterday, I sucessfully tested a burner in free air with a ceramic
ribbon. 
It ran nicely from very low idle to 15 psig.

The nozzle was made from insulating firebrick with 3/8" holes drilled 
top-to-bottom.  There is a manifold made out of 1/16" sheet metal to
connect 
the burner (Larry Zoeller side-arm design) to the brick.

The goal was to achieve a linear flame pattern under the burner.  What I
got 
is one that is about 3.5 inches long and 1.5 inches wide.

The unique thing about the design is that the manifold and the ceramic
brick 
(8" long) are made to handle 2 side-arm burners.  So when both burners
are 
firing, the length of the flame pattern should be 7 inches long.  The
flame pattern 
should be fairly continuous and uniform for the whole length.  This
should 
minimize if not eliminate that cold spot one gets between conventional 
burners.  The other thing is that ther ceramic brick should last a long
time 
in this application.

I will install the assembly in the new forge today and post pictures on
the 
photo site soon.

My thanks to John Emmerling's previous work and newletter article and to

other's thoughts on the subject.
