<p>A pyro-gasification reactor (3) of the downdraft type, which is adapted to be applied to a pyro-gasification plant (2). The reactor (3) comprises:•at least one first inlet (32), through which a predetermined amount of biomass is introduced;•a storage tank (31), into which the biomass to be pyrolyzed and gasified is introduced; · at least one second inlet (34), through which a fluidizing agent is introduced into the reactor (3) by means of a fluidizing agent introducing plant (A);•a core (4), in which the pyrolysis and gasification processes take place and which is arranged under said storage tank (31). Said core (4) comprises at least one first reaction chamber (41) and at least one first grate (43), which is adapted to support the biomass during the pyro-gasification process. The reactor comprises a cooling structure (5), which is adapted to surround the core (4), thus enclosing it, creating a hollow space (51). The cooling structure (5) is fluidly connected to said fluidizing agent introducing plant (A), so as to allow a fluid to flow through said hollow space (51). The second inlet (34) to introduce the fluidizing agent is arranged in correspondence to said core (4), thus allowing the fluidizing agent contained in said hollow space (51) to be at least introduced into said first reaction chamber (41).</p> |
