Boiler Maintenance

General Maintenance
A well-planned maintenance program avoids unnecessary down time or costly repairs. It
also promotes safety and aids boiler code and local inspectors. An inspection schedule
listing the procedures should be established. It is recommended that boiler room log or
record be maintained, recording daily, weekly, monthly, and yearly maintenance activities.
This provides a valuable guide and aids in obtaining boiler availability factor to determine
shutdown frequency, economies, length of service, etc.
Daily Maintenance
Daily Maintenance should include a check of the burner operation, including fuel pressure,
atomizing air or steam pressure, visual appearance, etc. Clean the observation ports during
periods of low fire or shutdown. Test the boiler level alarms and low water cutoff. Maintain
a daily schedule of sootblowing.
Monthly Maintenance
Check the condition of the refractory for significant damage or cracking. Patch and repair
the refractory as required. Frequent wash coating of refractory surfaces is recommended.
Use high temperature bonding, air-dry type mortar diluted with water, to the consistency of
light cream, for this purpose. This will seal small cracks and prolong the life of the refractory.
Any large cracks should be cleaned out and filled with mortar.
