Burner for burning powdered fuel |
摘要 |
A burner for burning powdered fuel in air. The air is divided into concentric annular currents. A tube (6) conveys primary air or gas. The tube is surrounded by another tube (12). The second tube conveys secondary air. The exit of the primary-air tube inside the secondary-air tube is surrounded by an annular baffle (26). The baffle is open at each end, has secondary air flowing through it, and extends axially beyond the primary-air tube as much as 25% of the tube's outside diameter. The thickness of the gap (25) between the primary-air tube and the baffle is at least 1.5% of that diameter.
