This is my first attempt-- Rocket Stove (5 gallon bucket with ash insulator, 6" stove pipe burn tube, tin can feed with tin can feed plate. Gasifer sitting on top, a piece of double-walled stainless pipe I had laying around. Some metal mesh is crammed in the bottom for fuel to rest on and holes are drilled around the top (gasifier jets). I put the gasifier on top of the hot Rocket and the thing really took off.. just few handfulls of grass pellets gave me 4 foot flames. Will try to figure out how to attach a video... (doesn't want .mov or .m4v extensions?? Will explore further. Here's screenshot...)
The glowing metal is good, that means you may be reaching the needed temps. The Orange flames are bad, that indicates unclean burn. I don't thing a clean burn can be achieved by a 5 gallon bucket based system as it's just too small. I haven't seen one that doesn't have evidence of unclean burn written all over it. Keep up the experiments though.
