Thank you very much for your advice on burners. The recomendation to use
comercial burner tips is because of just what? To get the flame to stay at
the end of the flame tube. Yes I get that. But just why is that important?
As it is now; The turndown range seems to be perfect. From a candle flame
all the way to Gee-Wiz.
The price is excellent. The amount of "Heat wasted by radiation of a hot
pipe which is not inside the box", is pretty small. And I'm also curious
about just how common is it for homemade burners to be accepted and used
which have some burning down inside the tube? Do most people even now if
there is burning inside the flame tube? Especially when they have elbows on
the flame tube. I mean I can see right thru mine because of no obstruction.
Otherwise I wouldn't have known,and brought up this subject.
Understanding "burning" is probably a key to "kiln firing".
This is so interesting, I'm having fun.
Thanks ,Steve Yahn
PS, I don't have a kiln made yet so my burners at present don't have a load
to work against. They are in the open.

Steve -
However slick you think your burners are working, they are crap compared to
what they will be with a good flame retention tip. Trust us on this. The
flame-retention tip will prevent flame-off and back-burning, and will give
you more efficient combustion, reducing your firing costs.

Yes, they know, because the burner tube gets very hot and corrodes quickly
over time. It is NEVER acceptable to operate a burner when it is
back-burning, with the flame originating from the orifice. Properly
designed homemade tube burners can work great, but not without
flame-retention tips.
