Applicated in rotary kiln (cement, lime, reduction, Li...)

External Structure

It is composed of pipelines, nozzles, metal corrugated compensators, butterfly valves, pressure measuring instruments and protective layers.
Figure 1.1 Five Channel Dual Vortex Fuel Burner

Component Introduction:
1. Pipelines: There are five pipelines from the inside out, namely central air channel, internal swirling air channel, coal air channel, external swirling air channel and axial air channel. The middle channel is a fuel oil pipeline or positioning observation hole for ignition, so it is habitually called a five-channel burner.
2. Nozzle: Processed from special materials, it is one of the key components to ensure the flame shape and service life.
3. Metal Corrugated Compensator: A main component for connecting pipelines, sealing and adjusting the flame shape.
4. Butterfly Valve: Used to adjust air volume.
5. Protective Layer: Refractory castable layer, which is poured by the user.
6. Pressure Measuring Instrument: Indirectly displays the ejection speed of the air outlet in the burner.
Our BN series multi-channel dual vortex low-nitrogen burner adopts patented technology and is customized and designed for different kiln types and process conditions. It can fully mix fuel with high-temperature secondary air under the action of primary air, improving the fuel burnout rate and bringing considerable economic benefits to users. At present, it has been widely used in rotary kilns in metallurgy, cement, lime, chemical industry and other industries.

Performance Advantages
1. Flame-holding Cover Design for Full Combustion: The flame holding cover forms a bowl-shaped effect, creating a recirculation zone in the flame center, increasing the contact time between materials and high-temperature flame, and the fuel burnout rate is greater than 99%.
2. Patented Dual Vortex Technology: The dual wrapping of axial air and external swirling air not only makes fuel combustion rapid but also makes the flame shape regular with high thermal temperature, lively and stable. The use of axial air and internal swirling air enables full mixing and diffusion of fuel with primary and secondary air, improving fuel combustion speed and flame temperature, and is suitable for various kilns.
3. Wear and Corrosion Resistance, Long Service Life: Can prevent scouring of the burner by pulverized coal.
4. Flexible Online Adjustment and Strong Adaptability: Can adjust the flame shape and intensity according to working conditions.
5. Energy Saving, Consumption Reduction, Low Nitrogen and Environmental Protection: Reduces nitrogen oxide emissions by 20%~35%.
