FuelCanister adds the FuelCanister. It's a cheap item which fills itself with as much coal and charcoal as possible on right click. The filled fuel Canister can then be used as a furnace fuel. It combines great efficiency and long burntime, because it smelts one item at a time, but also can smelt as much Items as 16 Stacks of coal by default. The max Fuel and Fuel types can be changed in the config.
