Abstract
Continuous charcoal production system in a vertical reactor with a concentric charging zone (1) and drying zone (2), a carbonization zone (3), a cooling zone (4) and a discharge zone (5), and a method for recovering energy from carbonization gases for the production of this charcoal, comprising the extraction of carbonization gas from the drying zone (2) and subdividing it into recirculating gas and heating gas, with the remaining gas exceeding the energy required to generate electricity; burning the heating gas in a hot gas generator (11); injecting the recirculating gas into a heat recovery unit (9); injecting the heating gas after combustion into the heat recovery unit (9), indirect heating of the recirculating gas; and reinjecting the heated recirculating gas into the carbonization zone (3) of the reactor (R).
