The Dangers of a Wood Burning Fire A wood-burning fireplace can be a relaxing and cozy experience. It also produces toxic combustion by-products. It is essential to know how wood burns, and how to use your fireplace properly. Choose the seasoned or kiln-dried logs. Logs that are seasoned are less moist and can be more hot than unseasoned logs. Burning Time The burning of wood is an effective and traditional method of heating. This kind of fire can release pollutants both indoors and outdoors that are harmful to the human body. A well-designed fireplace, used with skill can lessen the negative effects of burning wood. The amount of time a wood fire lasts depends on how hot it is. The temperature of the fire can affect the quantity of smoke produced, as does how much carbon monoxide is released. If the levels of carbon monoxide are high, they could impede the escape of occupants from a building that is burning. To prevent this from happening, it is essential to keep the fire at a low level of heat. During the first stage of a wood fire volatile gases such as methane and Methanol are released from the cellulose of the wood. These gases are non-combustible or combustible, based on the moisture content and the pyrolysis temperature of the sample. The temperature of pyrolysis can rise to 325 degrees Celsius. At this point cellulose starts to break down, forming tar and coal. This process is called wood pyrolysis. Burning wood releases toxic combustion products like dioxins and polyaromatic hydrocarbons and PAHs. PAHs are known to cause cancer and other ailments in animals and humans. They also have the potential to cause soil and water contamination. To minimize the effects of PAHs, wood must be burned in a properly ventilated area. A wood stove with an extended burn capacity can maintain visible flames while using a minimum amount of fuel. modern wood burner of burning involves laying the wood with lighter kindling and larger logs to keep the fire from burning out too fast. This technique can be used to build a an open flame that generates large amounts of heat for use at night or even while working. The length of the fire is determined by various factors, such as the moisture content of the wood. Dry wood will have a slower burning time than damp wood. The absorptivity of the sample surface also influences the duration of its burning. Simms [59] discovered that the required heat flux to ignite Mahogany and Oak samples with coated surfaces was significantly lower than without them. Temperature The temperature of the fire is extremely crucial. The temperature of a fire will affect the speed at which it burns as well as the amount of heat it creates. It also influences the risk to get burned. It also affects the amount of smoke produced. If there is too much smoke, it may cause irritation to the eyes and throat, so people should avoid breathing it in. When wood burns it produces plenty of heat and can even reach high temperatures. The temperature of a fire can depend on the kind of wood is used and the moisture content. For instance, wet wood will have a lower burning temperature than dry wood. This is because wet wood can absorb more water and less heat. It is important to use dry wood, and you should make sure that the wood is well-seasoned before burning it. When the wood is at a high burning temperature, a substantial amount of heat and ash are released. The amount of ash released will depend on the type of wood and the degree of heat. Some woods, such as larch and oak, produce very little ash when they burn. Others, such as birch, can create large amounts of ash. When the wood is burned, it will undergo the pyrolysis process in three stages. This process begins by a chemistry reaction which transforms the organic substances within the wood to carbon dioxide and methane. The gas produced is taken up by the air. When the wood is heated these gases will rise, and ignite the surface of the wood and create the appearance of a flame, which heats the wood until it combusts. The temperature of a wood burning fire can be extremely high and can cause damage to surfaces when it comes into contact with them. It is also essential to avoid touching the fire with bare skin because it could cause burns. You can lessen the chance of burning by wearing a pair of gloves and working in a ventilated area. Wearing a mask is also recommended when working around fires that burn wood to prevent breathing in smoke. Smoke Wood burning fires produce smoke, a mixture of gases and fine particles (also called particulate matter or PM) that contain harmful air pollutants. The smoke from wood combustion could contain harmful organic compounds, such as formaldehyde and benzene, and mineral particles such as calcium, potassium and magnesium. These particles can cause range of health issues such as respiratory diseases and cancer. Inhaling wood smoke can also cause people to inhale CO, an odorless, colorless gas which can be deadly in small amounts. The smoke that is produced by the wood fire is mostly due to volatile organic compounds (hydrocarbons) evaporating from the burning material. The smoke is made up of water vapor as well as the by-products of incomplete burning (such as creosote) and some non-burned substances, also known as Ash. When choosing the type of wood to use in your woodstove or fireplace, it is best to choose seasoned firewood. Logs that are split and stored away from the elements and left to dry until they are well-seasoned (a moisture content of 20-25 percent) will burn less quickly and produce less creosote. Knocking a log on both sides is a great method to determine the amount of moisture. Damp wood will have an uninteresting sound, whereas the logs that are seasoned will produce a sharp sound. The smoke and other combustion by-products are expelled through the chimney. If the ventilation system of the house is not adequate, the chimney could be not able to draw enough air and create an back draft. This can cause products of the fire to build up inside the house. This could lead to an accumulation of carbon monoxide as well as flammable cinders and creosote. Smoke from wood-burning fires could be particularly harmful to older people, those suffering from lung or heart conditions children, and outdoor avids. Smoke from wildfires can have a negative impact on the health of older adults, people with heart or lung disease, children and people who are active outdoors. Safety There are a few precautions you should take when using a wood-burning fireplace to minimize the chance of. For example it is recommended to make use of a fireplace or wood stove screen and keep any flammable items at least three feet from it. Smoke and carbon monoxide detectors must also be put in place in your home to warn you when hazardous gases are detected. It is also important to not leave a fire burning unattended, as even a small spark can cause an explosion. Also, you should employ a metal shovel and ash bucket to remove the ashes from your fireplace or wood stove and keep it away from anything flammable. Lighting the Fire To begin a fire, put an even layer of dry and cleft logs on the ground with ash. Then add a layer twigs and other kindling to the pile. Make sure there's enough space between each piece of wood to allow air flow, as this will help keep the fire from dying out too quickly. Add a few firelighters if you need some extra help to get your fire up and running. Open windows to let the fire get the oxygen it requires to burn brightly. This is particularly crucial for modern homes, that are often well-insulated and have no natural draft or ventilation. Once the fire has been started, you can add larger pieces of wood. But, it is important to keep in mind that even the most seasoned hardwoods such as oak and hickory can still release a large amount of creosote when burned and you should avoid burning them as much as possible. If possible, only burn the wood that has been seasoned or kiln-dried in order to minimize the chance of creosote forming up in your chimney. However, if you need to use fresh or newly cut firewood, make sure you do it with extreme caution because it will produce more smoke and create more creosote.
