How does this work?

Gravity…. is amazing. Our wood pellet hopper automatically feeds our 50BMG rocket stove fuel without electricity.

To speed the stove up, open the ashtray and allow more air into the stove, and this in-turn causes the fuel to burn hotter and will feed more pellets into the burn chamber.

The handle on the side of the hopper allows you to easily shut down the stove, even if you have a full pellet hopper.  The pellets left in the chute will fall into the burn chamber and then go out.
