Yeah there is a subtle difference between a woodgas stove like mine and something like a bush buddy which you feed continuously. Both have primary and secondary air intakes. The difference is that a woodgas stove depends on having the charcoal on top of the unburned wood. When you feed wood in from the top you reverse this.

Nothing wrong with a stove that you can feed. In fact that is probably just the thing when you don't know how long you might need the stove to run for. My woodgas stove must be pre-filled with all the fuel it will use. It's a bit like an alcohol stove that way. Once it's running you can't really add any fuel. But since I only ever boil water it's not really an issue for me.
