[TheForge] Ribbon burner nozzle

[Rick Korinek]

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.
