June,
I am sorry that you are having issues with your Olympic Torchbearer. =3D
Please give me a call @ 800-241-4400 and I will be happy to talk you =3D
through your problems. To clarify the burner discussion that is =3D
ongoing, We currently use an AM100 burner with a flame retention tip. =3D
We have used various burners over the years and have had the greatest =3D
success with these burners. I listen very carefully to these discussions =
=3D
and I try to use information gathered here to improve our product =3D
whenever possible.

Subject: Could use some help with backburning on Olympic gas kiln =3D
burners
This is the first day all week with no rain in the forecast that I could =
=3D
fire this small Olympic gas kiln. I don't know why I'm getting back =3D
burning since the beginning of the firing. I cleaned the burners and =3D
orifices very well before the firing. The shutters are open 3/8". They =3D
suggest 3/8 - 1/2" shutter openings. I have no idea what more I could do =
=3D
to correct this problem.
I've seen on line where another person with this kiln had the same =3D
problem with these Olympic burners and replaced them with other venturi =3D
burners; but I can't believe that there isn't another solution for this.
The kiln is now up to 1660+ degrees and I just hope this back burning =3D
won't stop me from getting to temperature. It's supposed to fire on 5 =3D
gallons and my 7 gallon tank is already less than 1/2 full. Fortunately, =
=3D
I have another 5 gallon ready to attach if the 7 gallon empties. Thanks =
=3D
for any suggestions.
Warm regards,
June

Bill,
Back burning can be caused by many things. The gas pressure can be too low=
,
the hose or pipe feeding the kiln can be too small, the orifice on the
burner could be incorrect, the burners may not be centered on the ports in
the floor, shelves that are too large or placed too close to the floor or a
blockage in the burner can all be factors. I have not spoken to June about
her specific problem, however I did see that she is using her kiln for salt
and soda firing. This is not recommended for a soft brick kiln. It is
possible that the salt and soda are glazing the burner(s) and causing a
blockage. I just do not know. Every situation is unique, that is why I
like to talk directly to the people that are having the problem. Gas kilns
are hard to kill and they tend to change hands during their lives. As has
been documented by you, they get modified. Sometimes with positive results
and sometimes with detrimental results. Please know that I am here to help=
.
Please feel free to call me personally at 800-241-4400 if you or anyone els=
e
has any questions.

Rob,
Welcome to the conversation.
Everybody needs to know that my circumstances with the Olympic updraft were
with a older style of burner having no flame retention tip - just a straigh=
t
pipe with, I assume, the GACO back end.
I have not fired with the AM100 burners that Rob writes about, so I have no
experience or opinions about them.
Rob - Would you please explain what circumstances might cause back-burning?
Could this be an obstruction in the burner, such as a spider web? Is this
too low gas pressure? If others have encountered this issue, perhaps an
explanation and remedies would be helpful.
Bill

I would imagine, in general, burners point up from the floor is
not a good configuration for a vapor kiln, especially if you are
putting the salt/soda in, in solid form.
