In a gravity hopper feed stove, there is a hopper, which is a rectangular tube full of coal that is open on the bottom, sitting on the fire. As the coal burns it turns to ash, the coal bed settles lower, and the coal in the hopper keeps the firebox full..
The limitation is that as the coal burns to ash, the ash tends to clog up the air passageways through the grates.. so the fire slowly starves for air.. The hopper does provide a supply of coal to the fire, but the fire still needs to have the grates shook to shake down the ash, to keep the fire's air supply open..
My personal problem with the Alaska Kodiak hopper feed stove is the grate design.. the back and forth circular motion doesn't seem to provide enough grinding/cutting action to break up hard crusty ash or small clinkers. If the coal burns completely to a powder, it would work fine, but that is pretty optimistic.. I think the Kodiak may occasionally need to let the fire go out and clean out the junk off the top of the grate.. I don't KNOW this , but it seems to me that it could happen,
The Grate design is like the old Potbelly stoves there is a Sq Grate frame with fingers all the way around then there is a Round Grate with finger in it then in the center there is a 6 finger dump Grate looks like a fork you put on the shaker handel and shake back and forth side to side the round grate and the dump grate moves together to cut the ash
on the grate frame with the new model you will have 4 inches of movement on my old model there is a outside handel
like the harman stoves witch will give you 6 to 9 inches of movement side to side also you can use the shaker handel but then you have to open the ash door to shake it down On the new stoves there is a slot cut in the ash door above the air slots
where you put the handel in on to the dump grate that is why you only have 4 or 5 inches to move but if you need more you can still open the ash door sorry Greg I just realized i put this in the wrong spot i hit the wrong quote button *censored* sorry
