The present invention relates to a double chamber pyrolytic burner for solid fuel comprising a combustion chamber, an outer jacket of diameter B, defining a toroidal interspace between the outer jacket and the combustion chamber, a cap which closes upwardly said interspace, a bottom and a ventilation apparatus coupled to the bottom, wherein the combustion chamber comprises a hollow cylinder of diameter D and height H, and a bottom coupled to the cylinder. The cylinder is provided with a first set of holes of diameter D1 arranged at a distance H1 from the upper edge and a second set of holes of diameter D2 arranged at a distance H2 from lower edge. The first set of holes and the second set of holes have a diameter respectively D1 and D2. The first and second sets of holes are arranged radially along the wall of the hollow cylinder according to an angle a between 12 and 36°. The bottom is provided with a central hole of diameter D3 and a set of at least three holes also of a diameter D3, equidistant from each other and arranged along a circumference of diameter between D and D/4. The pyrolytic burner also comprises a flow stabilizer ring arranged between the bottom of said burner and the bottom of the combustion chamber, provided with a central hole of diameter D4 and a shielding plate coupled to said flow stabilizer ring and arranged between the flow stabilizer ring and the bottom. The shielding plate is provided with a central body of diameter D5, and at least two brackets suitable for coupling to said flow stabilizer ring or to the bottom of the burner.
