This patent describes a stove comprising an enclosure having a front wall, a rear wall, top and bottom walls, and two side walls, a smoke outlet made in the top wall, an upper and a lower partition fixedly mounted to the walls in vertically-shaped relationship within the enclosure, intermediate and parallel to the top and bottom walls, a smoke space, and a cooling oven space being defined above the upper partition and between the upper and lower partitions, respectively. A grate extends within the enclosure intermediate the lower partition and the bottom wall, a combustion chamber and an ash-pit are defined above and below the grate respectively. An air intake is located in the combustion chamber. The grate comprises hollow cylindrical metallic ducts, which criss cross in order to form an X and which open outwardly at each end. The ends of each duct extend through and are fixed to the side walls permitting the ambient air to circulate through the ducts. Each of the ducts have an intermediate crossing portion that is substantially flattened, the grate being able to support a solid combustible, yet allowing therethrough by gravity the cinders into the ash-pit. Lateral semi-cylindrical upright pipes are closed at both ends and are fixedly secured to and projecting from the exterior face of each of the side walls between the top wall and the outer ends of the ducts. The side walls have first and second openings making communication between the combustion chamber and the pipes and between the latter and the smoke space, respectively.
