The industry features of stainless steel industrial coal burner for boiler

1.coal consumption decreased by 30%2.consumption-efficiency≥ 97%3.slag contains≤ 1% 4.burn-off rate≥ 99%5.emission≤ 50mg/m3

1.The fuel is evenly allocated with reasonable air distribution at the outlet of the pulverized coal burner. With a proper mixing point of the secondary air and the primary air, the length of the black flame at the outlet of the burner is usually controlled within 200-350mm in order to ensure the timely firing and sufficient burning.

2.A good aerodynamic field can be formed, which can facilitate sparking and an even mix of the pulverized coal and air. Meanwhile, slag-bonding also can be avoided.

3.The flame ejected by this machine possesses both the axial space rate and the rotating tangential component velocity.

1. there is enough distance among the burners. and flow air can be freely expanded and form recirculation zone in order not to interfere one another.

2. the flame cannot swash against the adjacent wall or block wall , which will lead to slagging in the adjacent wall or block wall. With regard to industry boiler, the basic layout form has four styles :

1. Quadrangular layout.

2. Front wall against back wall layout

3. Front wall layout.

4. Layout from top to bottom

  Burner layout dimension

Distance name	Distance (D means “nozzle diameter”
Burner centerline to cold ash bucket	(2-2.5)D
Vertical distance between the centerline of the line layout burner	(3-3.5)D
Horizontal distance between the centerline of the single-row layout burner	(2.2-2.4)D
Burner centerline to adjacent wall	(3-3.5)D
