I've given up with trying to capture the sin gasses & create the bio-char with an air tight kiln.

I'm now using an open air kiln with high sides 1200mm using corrugated iron & then quenching with water. The corrugated iron restricts the oxygen & reflects the heat. Only the top layer gets oxygen & you add wood as the top layer converts to charcoal. I have no shortage of feedstock right now because I'm thinning my trees.

The quality of the biochar is not as high (incomplete pyrolysis) but it produces multiple times more volume of charcoal for the same effort/time.

I'd love to capture the gas but haven't seen an economical way.

Yeah, to capture the gas there is a substantial amount of capital that has to be spent and that's not just something everyone can do. For small holders, homesteaders and residential doing what you're doing is the best way to go because you still get char and that's gold.
