Whether the Burner Head Needs Replacement

The rotary kiln burner head works under high temperature, high wind speed, and material erosion. Its condition affects flame shape, clinker quality, coal consumption, and refractory life. Don't wait for obvious failure—it causes bigger losses.

01 Appearance Check

Inspect during each kiln shutdown. Check flame-collecting hood, axial/swirl nozzles, center air components.

Severe wear: Replace head or parts.
Deformation: Don't weld on-site—contact after-sales.
Castable falling off: Stop use immediately, contact after-sales, repair with special castable.

02 Operation Warning Signs

Abnormal flame: If flame deviates or hits coating and adjustment fails—check head.
Quality drop, consumption rise: Poor air-coal mixing. Long-term loss exceeds replacement cost.
Coating/refractory damage: Check head immediately.

03 Replacement Strategy

Daily maintenance: Keep primary air cooling until kiln temp <200°C. Clean with compressed air and soft brush. Check head each shutdown.
Regular replacement: Replace head after about 3 years, even without obvious defects.
No self-repair: Welding affects precision. Ensure axial concentricity and radial flatness.
