Look for signs of wire-drawing or steam cuts on the valve seat and disc.
Lubricate the carriage travel chains or cables (if applicable) and check tension. Outage / Annual Checklist Completely rebuild the stuffing box with fresh packing.
Look for active steam or condensate leaks around the packing gland adjustment nut. 3. Step-by-Step Maintenance Procedures Packing Gland Replacement (Stuffing Box Re-packing) clyde bergemann soot blower maintenance manual work
Check the tension of the main drive chains. Adjust the take-up bolts if sagging exceeds manual tolerances. Lubricate chains with a dry-film graphite or specialized high-temperature chain lubricant that will not attract fly ash.
Back off the gland nuts slowly to release residual pressure on the packing set. Look for signs of wire-drawing or steam cuts
To ensure uniform cleaning, the lance tube should be "indexed"—meaning it rotates (often about 45 degrees) without forward motion at the start of each cycle to change the nozzle path and prevent localized wear on boiler tubes. 3. Electrical and Operational Safety
Adhering strictly to a Clyde Bergemann soot blower maintenance manual ensures that work is completed safely, efficiently, and with minimal impact on boiler operations. Regularly servicing the poppet valves, keeping the carriage drive lubricated, and checking electrical limit switches prevents catastrophic lance failures and expensive boiler tube damage. Proper upkeep directly correlates to sustained boiler efficiency, lowered fuel consumption, and extended plant uptime. Look for active steam or condensate leaks around
: Verify the elevation alignment of the blower. For retractable units, the poppet end typically must be raised approximately 1 inch for every 10 feet of travel to account for boiler expansion at full load. 2. Lubrication Requirements
