A heating device for burning fuel pellets (2) having a spherical combustion area (7), the surrounding wall of which is perforated (37), is disclosed. The combustion area (7) is surrounded concentrically by a wall(40) having perforations (36) and is spaced from the wall (10) of the combustion chamber. The space between the two walls (10 and 40) is utilized to hold the fuel pellets which are ignited by a heated medium directed from the outside towards both the walls (10 and 40). |
