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)
Remember: The boiler doesn’t care about your production targets. It cares that the soot blower works precisely as designed. That precision comes from the manual. Follow it. Work it. Live it.
After overhaul, you must perform a "dry run" – manually cycle the blower without steam for 10 full cycles, checking for smooth travel and correct limit switch activation.
