Abstract
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).
Claims19
Heating equipment for generating a seat of fire with the aid of solid fuel such as pellets ignited by heated gaseous medium such as air,
- characterized by a combustion area (7) which is surrounded by a first spherical wall (10) with a flame outlet (8), the surface of the combustion area (7) being perforated;
- by a space (6) constituted by said first wall (10) and a second spherical wall (40) situated outside the first wall (10), which space (6) is formed for the fuel, and the second wall (40) of the space (6) being completely perforated;
- and by a fan installation (14) which supplies the space (6) and the combustion area (7) with gaseous medium such air, the temperature of which can be regulated.
