Zhonghe After-sales Tips Issue 3 | Seven Key Points of Daily Maintenance

This guide introduces 7 core maintenance rules for SR burners to reduce faults and extend equipment service life.


7 Core SR Burner Maintenance Rules


1. Standard Shutdown Cooling


Keep primary air running until kiln temperature drops below 200°C to avoid nozzle damage and coking.


2. Daily Pipeline Leak Inspection


Check gas and coal pipelines daily and fix leakage to ensure stable combustion.


3. Regular Burner Head Cleaning


Clean coke and ash after cooling to prevent nozzle blockage and flame deformation.


4. Head Component Inspection


Check for wear and deformation; contact our team for timely replacement and repair.


5. Refractory Castable Maintenance


Repair damaged castables regularly to protect burners from high-temperature damage.


6. Concentricity Calibration


Calibrate burner concentricity after disassembly to maintain high combustion efficiency.


7. Valve & Instrument Calibration


Calibrate instruments and test interlock functions routinely to avoid safety hazards.
