Gasifier (downdraft), Internal Examination Video part 1 of 3

PART 1 of 3 of an internal examination of a downdraft gasifier, to see what and why happened during a 2 hour test burn, this is for development, and conformation of observed run, during the test burn, then at the end of the video, small changes where made (based on findings, and 3 more consecutive burns where done, all with great results, I would say, that the exam was worth it !!

This looks good for a 2 hour burn, and looks as if, as designed, you can get a considerably longer burn out of this gassifier. The white ash would be where the air flow was fastest and temperature highest. Take the ash 1 or 2 inches at a time, and rough out each area on paper to get a picture of your air flow: the brown and uncharred wood represents volumes that were bypassed by the airstream either by packing or tar-sealing. I can SO see this on my farm. Thanks!! - !

i have a question. can you provide us a schematic diagram for a downdraft wood - chip gasifier. thank you very much

thank you

how did you measure your burn ratio?
