David,

Charcoal is best, but you have to make it, so if the gas is cool enough use wood chips. Sawdust can restrict flow too much if it gets packed down. Steel wool costs money and it can rust from the moisture content.

lol i"ve been using hay david--i guess anything with alot of surface that doesnt restrict the flow would work--the only advantage to metal shavings are they can be washed out and reused i guess--when my hay gets nasty i just burn it in the gasifier--one guy on here used fiberglass

I'm headed to the shop to put together Beamer's compass to cut out some flanges. I will add a 1" or so spacer to help keep the cutter head at the right height for a good cut. Will post a vid.

Hello fellow Fab Shop members, I'm new to gasifiers and I've gathered "parts" from my various warehouses (read that spots in the yard), done a lot of reading and have done some tank cutting and practice welds, etc. Working on the imbert burner dimensions for my tank size. Will post a preliminary design for comments. I'm posting some "how I did it" vids for those with little or no exp. and hopefully nudge someone to get started with what you've got.

WOODCHIP GASIFIER
Here is a link to a very informative publication. Section 3.1 has a gasifier specifically for wood chips and critical dimensions for several sizes.

Hello all. I am new and starting to look at build of gasifier for an outdoor furnace. I will build Imbert style downdraft and use a combustion blower with a venturi type setup to draw syngas to a heating burner like an I.C. engine would draw the gas to the carb. I am also planning to have a high and low fire by venting air off of the blower outlet with a damper. I haven't seen anything like this and thought it would make for an interesting build maybe some new ideas for others.
REFRACTORY INFO:
Here is a link for a cheap castable refractory from hardware store materials, it is suitable for foundry use so it should work for gasifier: http://www.visi.com/~darus/foundry2/refractory.html
I will create a thread as build progresses beyond thinking about it.
