Why does my Chimney smell like smoke after a fire?
Over time, creosote and other byproducts build up inside the chimney and can cause soot when the fireplace is used. Soot also has an odor that smells like smoke or burnt materials. When the soot spreads around your property after a fire, the unpleasant odor often spreads with it.
What are soot or creosote deposits in a fireplace?
When wood burns in a stove or fireplace, it gives off combustion byproducts such as smoke, ash and wood particles. As air currents carry these contaminants away from the fire, they settle as soot or creosote deposits in the fire compartment, stove pipe or chimney. These deposits are harmful when they block airflow or catch fire at a later time.
Can chimney soot catch fire?
Creosote can ignite at temperatures as low as 451 degrees F (for context, a fire in your fireplace can burn in excess of 450 degrees F), and even just an 1/8” buildup of creosote is considered enough to cause a chimney fire.
Is chimney soot harmful?
Yes, soot and creosote CAN be dangerous. Both are topical and inhalation hazards. People who work in the fireplace maintenance industry must be aware of and avoid chimney systems. So while these dirty substances do naturally occur, they can cause various health issues for humans.

It's also possible that you will notice pieces of flaming creosote coming out of the chimney, even if you cannot see the flames directly. A loud cracking, popping or roaring noise.
What temperature soot ignites?
Carbon black and diesel soot ignite around, respectively, 580°C and 500°C in the reactor conditions. The combustion of small amounts of hydrocarbons injected inside the catalyzed traps provides enough energy to start carbon black or soot combustion at entering gas temperature as low as 150°C.
What is the black stuff in my chimney?
You may have some buildup of chimney creosote. Creosote is a black, tar-like substance that forms inside your chimney when smoke doesn't entirely escape. As it builds up, creosote can cause chimney fires, which can then lead to house fires.
What temperature does soot burn at?
500 to 600 degrees Celsius.The problem: Soot particles only burn above temperatures of 500 to 600 degrees Celsius. Yet the temperature of truck exhaust is increasingly dropping as part of the effort to minimize emissions of nitric oxides harmful to the environment.

Why is soot dangerous?
Dangers of Soot. Soot is harmful because a wide variety of natural and synthetic substances burn during a fire. As they burn, they create microscopic particles that contain chemicals, acids, dust, metals, and other hazardous substances.
What causes soot in a fire?
The residue, more commonly known as soot, is what’s left when fossil fuels like wood, coal, and oil haven’t completely burned. This is why oil and chemical fires produce such thick black smoke. Many items in modern homes contain plastic and other synthetics, which are made from oil. When this fuel burns, the carbon-based materials float through the air and spread further than the original scene of the fire. Homes in tightly packed neighborhoods that are next door to a house fire often receive soot damage even if they weren’t directly affected by the fire. It can also be produced in much less dramatic fashion by a fireplace that has insufficient ventilation. Over time, creosote and other byproducts build up inside the chimney and can cause soot when the fireplace is used.
How does soot affect HVAC?
The soot spreads widely and sticks to every exposed surface, creating a larger contamination area. Soot can cause serious damage to the surfaces it stick s to, and this damage can quickly become permanent. If it reaches the building’s HVAC system, it can spread even further through the structure.
Why do you call a fire restoration company 24 hours a day?
That’s why our experts are on call 24 hours a day, 7 days a week, because fires don’t make appointments. Soot and smoke damage restoration costs vary, depending on the extent of the damage.
Is soot a health hazard?
A fire is a frightening experience for anyone involved, but if you think the dangers are over once the flames have been extinguished, you’re wrong. The black residue covering walls, ceilings, and furnishings is not only ugly and hard to clean, but it’s a health hazard.
Can soot spread through HVAC?
If it reaches the building’s HVAC system, it can spread even further through the structure. Unless the soot is cleaned quickly and correctly, the particles will be inhaled, causing bronchitis and other lung disorders, as well as aggravating current conditions like asthma or COPD.
Why is soot flammable?
Soot cannot be prevented, and is the result of unburned fuel collecting and forming as a black powder, flakes, or a glaze on your chimney liner . Because it is unburned fuel, soot is highly flammable.
How does soot cause a fire?
A buildup of soot can cause a fire when the temperature inside of the chimney rises. As the temperature rises, the soot can ignite, causing a fire that can potentially reach other areas of the home, such as the roof. A buildup of soot will also prevent smoke and gases like carbon dioxide from leaving your home through the chimney. Instead, the smoke and gases can enter into your home, potentially causing an unhealthy environment and stains on walls, ceilings, or furniture. Soot can also create a foul, musty odor, which can worsen in summer heat and humidity.
Is creosote flammable?
Oftentimes, the creosote that occurs from these situations is highly flammable.
Can creosote build up in chimneys be prevented?
While creosote buildup in your chimney cannot be totally prevented , there are ways to reduce soot buildup in your chimney. Some of the factors that can increase soot buildup include the following:
What are Soot and Creosote?
When you burn wood in your fireplace, it produces a number of byproducts including ash, smoke, soot and creosote. Soot is a black powder that is largely comprised of unburned materials. When it is first produced, soot can be easily vacuumed up or brushed off.
What Fuels Should I Burn?
As we mentioned above, there are a lot of different fuels that you can burn in your wood-burning fireplace. Here’s a quick list of some of the things that you can burn to make sure that you limit the amount of soot and creosote that gathers in your chimney.
How do chimney sweeps classify soot?
Chimney sweeps generally classify soot by the fuel type that it was formed by when it was combusted.
What is the main cause of chimney fire?
Creosote is the main cause of chimney fire
What is smokeless coal?
This means it produces much less smoke and therefore less deposits when compared to none smokeless fuels. The soot produced is often a yellows grey powder which can be cleaned from the flue in most cases with a medium flail or brush.
Why is wood flammable?
Burning wood which is damp, in a limited oxygen environment, with insufficient heat or inadequate turbulence produces flammable creosote. It is flammable as the volatile compounds that were previously contained within the wood have not combusted inside of the fire box where they were supposed to. The volatile gasses that leave the burning area can condense within the chimney as creosote. This creosote is the main risk of chimney fire as it still has great energy potential.
Do you need to sweep a gas chimney?
Gas by nature does not produce much particulate soot. That does not mean gas chimneys do not require sweeping. Dust from the house gets sucked up the chimneys day to day, spiders build cobwebs which block updraft. leaves, twigs and all manner of wildlife infiltrate from the outside. Gas chimneys can usually be swept with very fine bristles such as Perlon. In older masonry flues that were previously used for solid fuel it is recommended to sweep these with a firmer brush or flail in order to the clear degrading flue material or previously built up soot.
Is smokeless fuel soot corrosive?
Some smokeless fuel soot. This can have a fairly high sulphur content and be corrosive when wet
Can you cover all types of soot?
In conclusion. There are many types of sootsnd we cannot cover every type in this short article. You will require various tools and techniques to deal with them all. Some chimneys will contain various mixtures of soot and as a chimney sweep you must be able to adapt job by job. I cannot over emphasise enough how important practicing what you learn in a real life sooty environment is.
What is soot in a chimney?
Soot is a powdery residue of unburned carbon particles. The soot, usually brown or black, is like a dust or smudgy smoke that settles on surfaces. At first, soot can be easily brushed or wiped off. But it gradually accumulates in layers in chimneys, fireplaces and stovepipes. Soot deposits may accumulate over time and reduce airflow up to 30 percent so that the flue does not vent properly. This may cause smoke to back up in a home and cause health problems.
What is the substance that sticks to the surface of a chimney?
Creosote is a tarry residue that condenses from wood or coal particles, hydrocarbons, gases and other airborne debris. These substances stick to the surface as they cool, forming layers of flammable deposits. Creosote may be dry and crackling to the touch, thick and flaky layers or shiny and hardened black gooey substances. Creosote forms as gases cool, so deposits occur when chimney temperatures are cool and when air is not hot enough to carry the particles out of the chimney. Restricted air supply also allows the sticky particles to settle.
How to clean creosote from chimney?
Stovepipes may be disassembled for cleaning, but brick chimneys are fixed and typically cleaned by scrubbing downward with a chimney brush from the roof and upward from the firebox with a wire brush. Homeowners are sometimes tempted to build a hot fire to burn out the creosote deposits. This is not wise because the creosote may burn as an extremely hot fire in the chimney and damage the chimney and house structure.
What happens when wood burns in a fireplace?
When wood burns in a stove or fireplace, it gives off combustion byproducts such as smoke, ash and wood particles . As air currents carry these contaminants away from the fire, they settle as soot or creosote deposits in the fire compartment, stove pipe or chimney. These deposits are harmful when they block airflow or catch fire at a later time.
How to burn wood for a fire?
When starting a fire, hold a burning kindling stick or wad of newspaper at the open flue. This heats the air so that creosote and soot are carried up the hot airflow where they're less likely to settle in the chimney. Clean the chimney or stovepipe regularly. And check the damper to ensure smooth operation and efficient airflow. Use a chimney cap to keep out leaves, wildlife, bird nests and other accumulations that block airflow .
