The fuel stocking shaft (2) is connected with a burner (7) mounted in the combustion chamber (4). For initial air supply to the combustion chamber (4), the door (6) of the fuel stocking shaft (2) is equipped with a valve. The burner (7) contains of double- wall housing with a hollow channel (9). The housing of the burner (7) has an opening (12) for secondary air supply to the channel (9) and openings (11) for releasing hot air from the channel (9). A metal ring (10) is placed in the channel (9) of the burner (7) to decrease the space for combustible gas entering the channel (9) and at the same time to increase its diffusion. While fuel is burning, the released combustible gas from the combustion chamber (4) gets into the channel (9) through the ring (10), where it gets heated and mixed with the secondary air and thus produces a combustible mixture. |
