Abstract

1.estufa, characterized by being constituted by a body, preferably rectangular prismatic, in which three overlapping sectors are defined, a lower determinant of the combustión chamber and an upper one for thermal exchange, in which the appropriate evacuation conduit is established of smoke and also characterized in that in the intermediate sector, corresponding to the combustión chamber, its base and its side walls are provided with a refractory lining, while on its front face a loading mouth is provided with a preferably transparent door, it having been foreseen that in its rear wall and inferiorly there is established an inlet for the entrance of the combustión air, which travels along a pipe that ascends vertically through said rear wall, it is bent forward partially overlapping the upper zone of said combustión chamber and, then folded, on itself to return again at the lower level, until access to the combustión chamber by its base, all in order that the combustión air undergoes a preheating process, prior to combustión, in which it reaches a high temperature that guarantees optimal combustión. 2.estufa, according to claim 1, characterized in that in the upper or heat exchange chamber a plurality of oblique tubes are established, which substantially intercept the passage of the fumes from the combustión chamber to the evacuation conduit, having been provided that in correspondence with said upper chamber there is an enclosing partition defining a perimeter chamber in which the mouths of the said heating tubes are established, with the annular chamber closed superiorly and inferiorly, while in its external lateral wall and near its upper and lower edges respective alignments of holes are established through which communication is also established with the outside, the lower alignment of holes determining the access for ambient air and the upper alignment the hot air outlet, with the particular feature that said annular chamber it is compartmentalized by an intern annular partition edio that boosts heat transmission. 3. Stove, according to previous claims, characterized in that the lower sector of the body defines a support base that forms a chamber of section coinciding with the general section of the stove, open inferiorly and provided in its side walls with large ventilation holes.
