I have an idea but i don't know if it works.
I have build a lot of wood gasifier stoves for bushcrafting as you don't need much wood as fuel, it gives just little smoke at the ignition and once it burns almost no smoke.
I also have a small rocket stove and it also burns perfect.
I was thinking about making a wood gasifier that has insulation so it burns hotter and cleaner (like a wood gasifier in a rocket stove)
Will this work?
I don't know if it would be possible to put a barrel on the wood gasifier so it is like a rocket mass heater. Will this work?
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.

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...)
