Yo out there! Has anyone ever heard of or know anything about a
"cross-draft" gas kiln? I think he said the burners come in on the bottom
left side of the kiln...

Sure. My second gas kiln started life as a small conventional catenary
arch down draft, with two cheap venturi burners on each side and the flue
in back. The second time I rebuilt it, the burners were pretty much burnt
out, so I rebuilt the thing as a crossdraft, with two larger homemade
bendel burners (these are probably discredited these days, but they worked
well enough and they were almost free to build) on one side and the flue on
the other. I think it worked better as a cross draft, because the path of
the flue gasses (so I theorize) was simpler and more direct. My current
oil-fired salt kiln is a sort of cross draft with only one burner.

Anne -
A cross draft kiln is usually just a down draft kiln where the primary draft
through the kiln is from side-to side. The burners or firebox(es) are on
one side, and the flue is on the other side, rather than having the flue in
the center back like most donwdraft kilns. The cross-draft design work
especially well in catenary arch kilns, since they have a smooth sweep of
arch from the burners on one side to the flue on the other side. When I
first learned to build kilns in Humboldt County, California, that is all we
built. Free hardbrick from old sawmill dry-kiln boiler fireboxes, cheap
gas, cheap clay, good fun.
