Spring Start-up Checklist for Seasonal Boilers

Spring is here. For many heating boilers, this means shut-down. But for process boilers that were idle during a slow season, it is time to wake up.

The 'Slow Start' Protocol

WARNING: Never fire a cold boiler to 100% immediately. Thermal shock damages steel.

Step-by-Step Restart

1. Inspect Waterside: Open the manhole. Is there rust? Sludge? If yes, flush it out.

2. Check Pumps: Spin the pump shaft by hand. It should turn freely. If stuck, the bearings may need grease or replacement.

3. Fill Slowly: Fill with treated water (softened + deoxygenated).

4. Low Fire: Fire the burner on "Low" setting for 15 minutes, then off for 15 minutes. Repeat this cycle until the water reaches 60°C.

5. Tighten Bolts: As pressure builds, thermal expansion occurs. Re-tighten manhole and handhole bolts to prevent leaks.

6. Safety Test: Before going full load, manually trip the Low Water Cutoff to ensure safety systems work.
