Check for axial play in the main drive shafts. Replace any bearings that exhibit roughness or excessive clearance.
Verify upstream line pressure. Readjust the poppet valve pressure screw using a calibrated mechanical gauge installed on the blower body. 6. Preventive Maintenance Checklist Monthly Checks Inspect visually for steam or oil leaks. Listen for unusual grinding noises during operation.
But never neglect the physical manual. Keep a laminated copy of the mounted next to each blower.
Inspect the lance tube, carriage, and protective canopy for visible distortion, structural damage, or steam leaks. clyde bergemann soot blower maintenance manual work
Inspect the drive chains or cables for sagging. Adjust the tensioners according to manual specifications to ensure smooth carriage movement.
Ensure the main beam tracks are free of debris, scale, and heavy grease. Tracks should be kept dry or coated with a dry graphite film lubricant—never use heavy tack grease, which traps abrasive coal ash. 4. Poppet Valve Servicing and Adjustment
: The lance tube must be perfectly aligned with the wall box to prevent it from rubbing against the boiler tubes. Check for axial play in the main drive shafts
Check the "droop" of the lance tube. Excessive bending during operation can be mitigated by ensuring proper support structures and hangers are in place. 2. Hot Checkout (Operational Validation)
– many power/industrial plants keep paper manuals in the maintenance library or online portal.
Clean the stellite-faced valve seat. Check for pitting or scoring. If minor damage is present, lap the valve seat using a specialized lapping tool and fine compound. Readjust the poppet valve pressure screw using a
