1. Reasonable structure design, fire adjustment easily, not only adjustment air volume of axial air, swirling air, but also adjustment outlet section area of axial air ,swirling air and coal air, to reach the goal of change outlet air speed of burner, to ensure fuel burning normally;
2. Less use of primary air, and coal air mix with primary air, secondary air fully, make burning complete, to reduce coal consumption effective;
3. Nozzle is made of special material, heat resistance and replacing easily;
4. Fire cover forming bowleffect, there is not high swirl with fire at beginning, to avoid the peak value of temperature, make the fire temperature distribute uniform and reasonable;
5. Because the combustion air mix pulverized coal fully, the burning is fast and safety, CO and NOX content from kiln tail exit gas are reduced, in favor of equipment operation safety and realize environmentally friendly production;
6. Flange connection for each air pipe of burner, remove and maintenance easily;
7. Adaptable for coal quality, burning low quality coal.
