Im looking into supplementing our heating wood with mixed pressed paper briquettes does anyone know a good recipe for extra hot burning or longer burning logs. is it better to mix the briquettes with biomass like grass vs. charcoal or wood chips? how about semi woody material like rasperry canes or pinecones? i would like to make use of all of the uncoated paper that comes through here and it would be usefull to see what options for my standard woodstove or for outdoor cooking that briquettes might have.
I would burn wood in a wood stove. It has the right structure and will leave minimal ash. Compressed paper will have impurities (not many maybe) and some of those may be things that don’t burn well and are emmitted to atmosphere. Raspberry canes (if completely dry) and pine cones are good for starting the fires but they burn too quickly. You will keep warm though having to visit the stove frequently. You could use compressed sawdust/woodchip blocks, but even they burn away quickly. They provide a fair amount of heat, but really dry logs are the best way to go. If you have a batch rocket stove you could burn more materials as they have a fiecer fire and higher temperature so can burn the impurities, though it is not controlled so you can’t be sure of correct combustion.
