None of those is reburning. You'll use 3x as much wood. Study rocket mass heaters. Several commercial stoves incorporate the same idea: insulate the burn chamber, and (some) add extra forced air into the burn box, igniting all the byproducts. That also means you end up with no creosote. It's also the reason why non-reburn stoves build up creosote and eventually, when the stove pipe sets on fire, it's a 3,000 degree rocket that can't be put out.
And yes, there are ways or things you can burn to clear creosote. But why haul 3x the amount of wood, and have that extra maintenance? That if you don't do, burns your house down. Plus, you're refilling the fireplace 3x as often.
