[TheForge] Ribbon burner nozzle

[Grant Marcoux]

Most optical pyrometers are made for inspections of engineering spaces, HT
pipe clusters, etc., vs. forge use.  Most do not read high enough for forge
use.  I use a digital pyrometer, a Fluke Model 51 with an 12" HT probe.
This unit will read up to 2500F and has max temp recording capacity.  I have
also a Paragon analog model, but it has proven insufficiently accurate and
delicate.  The analog types are generally considered less accurate and more
delicate, but are much cheaper.  The Fluke 51 runs from $185.00 to $200.00,
but is accurate to within 1/10 degree F, so they claim.  I use it for heat
treating.  Grant

Knife supply houses have analog pyrometers from $100.

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.
