Abstract: A charcoal manufacturing device includes at least two bottomless furnaces of which, in operation, at least one is in a carbonization phase and at least one other is charged with wet wood to be dried. An incinerator is provided for burning the gas produced during the carbonization phase, connected to the at least one furnace. A first hot gas diluter is connected to this incinerator and an extractor is connected to the first diluter. An optional washing device is connected to the extractor. Hot gas produced by the at least one furnace during the carbonization phase is drawn off upstream of the extractor and conveyed to the at least one other furnace by a system that includes a second hot gas diluter. This second diluter renders the temperature of the hot gas compatible with the wet wood to be dried.
