Atomized Explosions

Essentially, backfires occur when your oil furnace misses ignition: If the burner doesn’t ignite as intended, atomized oil fumes can build up; when ignition finally occurs, the fumes typically cause a small explosion.

Similarly, How do you adjust the air mixture on an oil burner?

How to Adjust the Air Intake on Oil Burners
  1. Remove the cover on the air intake valve, and check to see if it is clean.
  2. Check the amount of soot that has accumulated from the burner.
  3. Find the air intake on the fan, which should be located on the left side of the burner.

Smoke. If you smell smoke or your smoke detector goes off, turn off your furnace immediately. Smoke odors usually result from a blocked chimney that forces the smoke to go through the ductwork rather than out the chimney. A professional chimney cleaning should resolve the smell.

How do you troubleshoot an oil furnace?

How to Troubleshoot Your Oil Furnace Ignitor
  1. First, shut down the furnace if it is operating.
  2. Close the oil valve on the line connected to your furnace.
  3. Cut off the circuit breaker.
  4. Remove the access panel.
  5. Locate the blast cone, which should be positioned below the oil burner.

What causes an oil boiler to soot up?

The three main reasons for incompletely burned oil that causes puffback are a leaky fuel line, a bad shut-off valve, and when the nozzle that shoots oil into the furnace becomes clogged. If the pipes that carry oil to the burner leak oil when the furnace is not running, air may enter the burner where it is compressed.

What comes out of a condensing boiler flue?

During the operation of condensing boilers, exhaust gases are expelled out of the flue; a condensing boiler is able to extract and use much of the heat from the gases before the flue gases discharge. This ability to extract more heat from the fuel it consumes makes it more efficient and also reduces emissions.

What causes furnace filters to turn black?

Carbon monoxide: This odorless, invisible gas is the byproduct of incomplete combustion and can cause soot deposits on your furnace filter. This can transfer to the dirt and dust collected on the furnace. If left wet long enough, black, sooty mold can begin to grow and spread to the furnace filter.

Is oil smell in house dangerous?

What causes oil burner puff back?

Puff backs occur when an oil-burning furnace doesn’t ignite when it should. Oil vapors build up in the ignition chamber, causing an explosion when the igniter finally triggers. The explosion blows soot and other debris through the furnace’s exhaust system and into the heating system, which carries it into the house.

What comes out of a condensing boiler flue?

The truth is that, with proper burning techniques, no smoke should be visible from our chimneys.

Why is there so much smoke coming out of my chimney?

Occasional puffs of smoke that enter the room from beneath the chimney breast are usually caused by downdrafts, or air rushing down the chimney in spite of the upward air flow caused by fireplace heat. Downdrafts often occur in windy weather. If the problem is infrequent, it is usually not worth taking the time to fix.

Why is my furnace blowing out soot?

1) Soot is the result of incomplete combustion, meaning that your furnace isn’t burning the gas properly or efficiently. 2) Soot can be deposited on the heat exchanger, acting as an insulating barrier. This insulation barrier lowers your furnace’s efficiency, increasing your energy bills as a result.

What causes thick black smoke?

Thick, black smoke indicates heavy fuels that are not being fully consumed. At times, black smoke can be an indicator that a manmade material is burning such as tires, vehicles or a structure. As a general rule, the darker the smoke, the more volatile the fire is.

What does soot smell like?

If your chimney smells like asphalt or bad barbecue, then you have creosote and soot build-up. Creosote comes from wood smoke. It is a dark, flammable tar that is absorbed by the masonry inside your chimney. Soot is black and powdery and is mostly made of amorphous carbon.

What’s the most common cause of puff back?

Puffback can also be caused by a partly clogged or cracked nozzle, improper nozzle angle, cracked electrodes, poor adjustment of the air-fuel mixture, a defective spark transformer, shorted ignition cables or dirty or low-grade fuel. The aftermath is usually the main problem.

What causes soot in a boiler?

Causes of Soot Buildup

Soot is the inevitable result of burning fossil fuels, and boilers that run on gas or oil produce soot simply by doing their job. Large amounts of soot can be caused by a dirty, clogged or malfunctioning burner, inadequate draft or a low air-to-fuel ratio.

What causes soot in a boiler?

Boiler flues are a crucial part of your heating system. They are a way for combustion fumes that have been created by your boiler to be released outside the home. The two main gases your gas condensing boiler produces are water vapour and carbon dioxide.

What would the result of excess oil in the combustion chamber be if it were ignited?

When the oil eventually ignites, a puffback can occur. A clogged burner full of dirt, dust, fuel residue, rust or corrosion can cause a misfire and allow excess fuel to build up in the combustion chamber. This may eventually lead to a puffback when the fuel at last ignites.
