The thing about this design is that it hardly produces any smoke and can even be used inside. The only problem is that the fire starts at the top, and moves downwards.
So if you want to continously feed it new fuel, you need to feed at the bottom.
Am I wrong in thinking a stoker is some kind of conveyor belt? My english isn't my native language, and I've had to search for a while before I figured out what an "auger" actually was (still not 100% sure about what it is)
If it is somekind of conveyor belt, I wouldn't know how to use it to feed the bottom of the stack.
Anything you find on google, I would be more than intrested to know.
