All Scenarios
Soot Buildup / Poor Combustion
Stack temperature has been trending upward over several days. Black smoke is occasionally visible and fuel consumption is increasing.
Symptoms you observe:
Rising stack temperature over timeBlack smoke from the stackIncreased fuel consumptionReduced boiler efficiencyPoor heat transfer
Step 1 of 4Decision Point
Analyze flue gases (O2, CO2, CO levels)
Flue gas analysis reveals whether the air/fuel ratio is correct or if combustion is incomplete.
