Mr Switchgrass - burning/gasifying switchgrass

Mr Switchgrass is an inverted downdraft gasifier design that burns/gasifiers chopped switchgrass or weeds with little to no smoke problems. A rule of thumb is that each section will burn for a solid ten minutes at full flame. I measured 66 lbs for one load and it ran for about 40 to 50 minutes.

The cyclone filter did not turn out the way I had planned. All I'll say is that when one plans on welding an old pot to the bottom of the cyclone filter (in order to provide room for the ash) make sure the pot is not an aluminum pot! You can see the test setup in picture 4.
