STUFA GASSIFICATRICE

A gasifier stove (1) comprising a containment structure (2) housing a storage tank (3) for biomass fuel (4), a gasification crucible (6) connected to a combustion chamber (15) and being fluidically connectable to a heat exchanger, wherein the gasification crucible (6) is hollow and extends axially, along a vertical axis (Y-Y), from a lower end (7) having a first opening (8), to an upper end (11), having a second opening (12). The gasification crucible (6) is connected to the tank (3) by means of an outlet pipe (14) which leads to the crucible (6) through a feed hole (114), positioned, along the vertical axis (Y-Y), between the lower end (7) and the upper end (11). Advantageously, the gasification crucible (6) has a variable cross-section along its axial extension, measured perpendicular to said vertical axis (Y-Y), and, at the lower end (7), the first opening (8) has an inlet cross-section smaller than a feed cross-section at the feed hole (114) of the pellets (4).
