In my titanium tent stove, I’ve been burning the pressed sawdust/wood pieces and they burn much longer than any softwood. The can be found in bricks or log shaped. In my stove, the smaller ones ignite better. I think the bricks sawn lengthwise might be even better. You add them to a fire that’s already hot. Our farm store sold a 20lb bag of kiln dried bug free hardwood for about $10, and that works too. Whatever you decide, test it at home so you get no surprises. DON’T plan on the chemical based fire logs in a stove. Just trust me on that one. Also, if using a Seek Outside Ti stove, replace or discard the old style spark arrestor. Thank me later.
