Abstract (en)

A device and method for the gasification of wood, according to which, inside a reactor (22) housed within an inner casing (4) with vertical axis (2a) and equipped with an oxidation zone (7) located near the base (6) of an outer container (2) containing said inner casing (4), at which a plurality of fluid conveyor elements (8, 8'), supplied with air from an external source (21) and positioned above a zone (9) for the discharge of the gas produced by the reactor (22), are oriented in such a way as to create, in the oxidation zone (7), a gaseous flow (8g) containing the gas, rotating about the longitudinal axis (2a) and moving forwards towards the discharge zone (9), which comprises a diaphragm (13) across the longitudinal axis (2a) and having a discharge hole (14); the diaphragm (13), together with the vertical walls of a lower section (4b) of the inner casing (4), constitutes a transit duct in which the gaseous flow (8g) is intercepted and suddenly diverted towards the discharge hole (14), causing the release of solid particles, which accumulate on the diaphragm (13) and on the inner walls of the lower section (4b), providing them with heat insulation and protecting them from any direct contact with the following gaseous flow (8g). <IMAGE>
