Process and reactor for continuous charcoal production

A reactor for continuous charcoal production, with a vertical structure comprising in sequence:

• a top charging zone, a drying zone, a carbonization zone, a cooling zone and a discharge zone, whereby the charging zone has a cross-section smaller than the drying zone and has an extension extending into the interior of the drying zone, forming an annular space around the extension,
• characterized in that at the top of the drying zone, at least two outlets for extracting gases are arranged in a diametrically opposed manner, and
• the charging zone is arranged concentrically in relation to the drying zone, and wherein the ratio between the diameter of the charging zone and the diameter of the drying zone is between 0.68 and 0.72.

Vegetable tar and pyroligneous extract recovered in the interconnection from the top of the reactor to the heat recovery unit, where the recirculating gas mass passes.

Vegetable tar and pyroligneous extract recovered in the interconnection between the top of the reactor and the inlet of the hot gas generator.
