What i have done to control temp and pellet consumption on my rocket stove. Cool accidental effect with this is the tube heats up and starts gasification of the pellets before they are burnt which causes a pretty cool blue flame and lots of heat. A simple brick makes a easy lid and keeps 99% of smoke in, sometime if the brick is not good enough air will get drawn down the tube allowing the "wood Gas" to be ignited and it will burp out a flame lol. Also have noted allowing too much air around pellet feeder will allow smoke back only up the pellet tube, not anywhere else.

Hi Roak,   Thanks for showing us your stove in action. What kind of a slide would you develop to accommodate a hopper as well?

Your welcome! Anytime! Not sure on a hopper, maybe wall mounted hopper with a flex pipe to the tube? i am pretty happy with what iv got now, the hopper holds 3.1lbs of pellets and will run out as fast as 20 min or as long as 45min depending on the setting.

it looks like the draft changes with the position of the pellet basket.  Does that mean at lower drafts smoke is generated?

Looking outside at the chimney i see no smoke depending on position. I think what is happening is as i move the basket back i am getting less draw thru the basket and that allows smoke up the basket. I do know that with the basket all the way forward, not allowing any air around basket i can almost leave the lid off the tube. Flame color also changes with position which tells me air to fuel ratio is changing also.  The basket is only about 1.5 inch off the floor of the burn tunnel iv never had any ash problem, i have alot of draft which pulls the ash down the burn tunnel and it gets trapped there intentionally by a necked down heat riser. I will post another vid here in about 30 min with some details.

I have seen this before, https://www.youtube.com/playlist?list=PLyRBSIGadacAkctGskHlAwM4bL8pdOzeN   Zero's rocket stove uses much the same method.     I have been thinking of how I can do this with wood chips...

Nice design, but WAY to much work to build in my book for something that gonna burn up. Wood chips would be hard due to there inconsistent size but not impossible. i think it would work in a 6+ inch system or bigger to help keep the wood chips from jamming up?

I have been brainstorming about how to do it.     At the present time I simply line the outer walls of my stove with wood chips and in the center use regular twigs to get it kicked off.

Another thing I have seen done is to use a stainless steel dish drainer and burn them like a TLUD stove.      

I have been thinking about making strings with ceramic fiber and then dipping them in sodium silicate to make it rock hard then make the design of the screen shown above.

Yep you have to do what works for you.
