Abstract (en)

A firebox (10) for a combustion apparatus, advantageously but not exclusively using biomass or biofuel, comprises a base structure (11) defining a combustion chamber (12) and a chimney (13) for the smoke, and has a door (16). The chimney (13) comprises at least a segment with a flue, cooperating with the combustion chamber (12), which is provided with a first pipe (19) and a second pipe (20) for the passage of the smoke. The first pipe (19) is associated with choking means (21) and said second pipe (20) is associated with filter means (23) located, according to the direction in which the smoke travels from the combustion chamber (12) toward the outside, before the first pipe (19) merges with the second pipe (20). The choking means (21) are associated, by means of connection means, to the position of the door (16), so that, with the door (16) open, the choking means (21) are in a position of opening the first pipe (19) and with the door (16) closed the choking means (21) are in a position of closing the first pipe (19).
