<p>A pellet fuel burner (10), such as a cooking grill, has a fire box (30) with a generally open top plane. A pellet burner unit (50) is disposed in the fire box below the cooking surface (14). A pellet feeding device (66) opens into the fire box and is disposed so as to feed pellets into the burner unit. A pressure box (82) has an inlet supplied with combustion air at a positive pressure. A plurality of outlets are provided in the pressure box and disposed so as to create a turbulent combustion air flow in the pellet burner unit. The outlets may include a first outlet (90) disposed above the burner unit and a second outlet (92) disposed below the burner unit. The turbulent combustion air flow and supply of pellets, particularly corn kernels from the pellet feeding device, allow for a continuous sustained combustion of the fuel in the pellet burner.</p> |
