Troubleshooting Scenarios
Walk through real-world boiler emergencies step by step. Make decisions at critical points and learn the correct operator response.
Low Water Condition
criticalEmergencyThe gauge glass level disappears and the low-water alarm sounds. The feedwater pump appears to be running.
High Pressure Condition
criticalEmergencyBoiler pressure is climbing rapidly past the normal operating range. The pressuretrol has not shut off the burner.
Flame Failure
highCombustionThe burner trips on flame failure. The flame scanner alarm activates and fuel is shut off automatically.
Water Hammer in Steam Lines
highOperationsLoud banging noises are heard from the steam piping. Pipes are visibly shaking and support brackets are stressed.
Boiler Tube Leak
highMechanicalFeedwater consumption has suddenly increased. You hear a hissing sound near the boiler and notice steam pressure dropping.
Foaming / Carryover
mediumWater ChemistryThe gauge glass shows bubbling and unstable water level. Steam users report wet steam and heating equipment is performing poorly.
Soot Buildup / Poor Combustion
mediumCombustionStack temperature has been trending upward over several days. Black smoke is occasionally visible and fuel consumption is increasing.
Draft Problems / Flame Rollout
criticalCombustionThe burner flame appears to be rolling out of the furnace opening. There is smoke escaping from observation ports and the furnace pressure reading is positive.
