Why is my boiler making black smoke?
Why is my boiler making black smoke?
Improper burning is the cause of black smoke coming from a boiler. If the oil does not burn normally, it will produce a dark-colored smoke that may be seen from the rooftop vent or wafting directly out of the boiler. It can also be caused by oil building up in the combustion chamber due to delayed ignition.
What does it mean when your boiler is smoking?
If you see soot or smoke emanating from your oil-fired boiler, sometimes accompanied by increased boiler noise, the condition is usually caused by “puffback.” A puffback occurs when unburned oil in the bottom of the combustion chamber is heated up and explodes. This can damage the boiler.
What causes black smoke in an oil fired boiler?
Re: Probable reasons of black smoke in oil fired boiler. Some possible reasons include nozzle fouling or wear, low oil feed pressure, insufficient air for atomization (if so equipped), insufficient combustion air (fan problem), contaminants in fuel, etc.
What causes smoke in a pressure jet boiler?
When a stackpipe leak occurs, soot and smoke are blown into the interior of the home, causing black stains on the walls and ceiling inside the boiler room and living area. The pressure-jet oil burner’s fuel pump supplies oil to the burner nozzle at 100 pounds per square inch or more; this atomizes the fuel, promoting complete combustion.
What happens if you have an oil leak in your boiler?
This can damage the boiler. Depending on the quality of the oil, it also can disconnect the flue stackpipe connection. When a stackpipe leak occurs, soot and smoke are blown into the interior of the home, causing black stains on the walls and ceiling inside the boiler room and living area.
Why do I get black smoke from my engine?
Piston Rings are designed to prevent the infiltration of engine oil inside the combustion chamber. If there is any problem with the piston rings, the engine oil starts flowing into the combustion chamber. The combustion of the mixture of this engine oil and the fuel delivers black smoke.
What does black smoke from a boiler mean?
Black smoke indicates that furnace oil is being fired in the boiler . This may be either during start up or as additional susupport for the coal burners for flame stability. White smoke from the chimney is due to ash carry over in the flue gas.
Where does smoke come from in an oil boiler?
Nevertheless, if a puffback occurs and the flue vent connector is in good condition, soot and oily smoke exits unnoticeably through the stackpipe. Inspect the floor below the burner oil supply piping regularly.

Why is my oil bloiler putting out black smoke?
Hexonx is correct with the info he puts in his post; once the inside of a boiler accumulates a certain amount of soot because it hasn’t been thoroughly cleaned each year, the heat exchanger clogs up with soot, then clogs the flue, then clogs the chimney.
