The Dangers of a Wood Burning Fire A wood-burning fireplace can be a comfortable and relaxing experience. It can also release harmful combustion by-products. It is essential to know how wood burns, and how to properly use your fireplace. Choose mature logs or kiln dried logs. Seasoned logs are less moist and can be more hot than unseasoned logs. Burning Time Burning wood to produce heat is a well-known and efficient method of heating. However, this kind of fire can release outdoor and indoor emissions that can be hazardous to the health of humans. A well-designed fireplace, when utilized with care can lessen the negative effects of burning wood. The duration of a fire is dependent on the temperature. The temperature of the fire influences the amount of smoke generated, as well as the amount of carbon monoxide released. If the levels of carbon monoxide are high, they may hinder the escape of people from a burning structure. It is important to keep the temperature of the fire at a lower level the fire in order to prevent this. During the first stage of a wood fire, volatile gases like methane and Methanol are released from the cellulose of the wood. These gases are combustible but non-combustible depending on the moisture levels and the pyrolysis temperature of the sample. The temperature of process can rise to 320 degrees Celsius. At this point cellulose begins to decompose and forms charcoal and tar. This process is known as wood pyrolysis. Burning wood releases other toxic combustion products like dioxins, polyaromatic hydrocarbons and PAHs. PAHs are linked to cancer and other diseases in humans as well as in animals. They can also cause contamination of soil and water. Wood must be burnt in a location which is adequately ventilated to limit the impact of PAHs. portable wood burning stove with an extended burn capacity can keep visible flames while using a minimum amount of fuel. This method of burning involves layering the wood with lighter kindling and heavier logs to keep the fire from burning too fast. This method can be used for an open fire to generate high heat, either overnight or during your work hours. The duration of a wood fire depends on many factors, including the moisture content of the wood. Dry wood burns more quickly than damp wood. The sample surface's absorptivity also affects the duration of its burning. Simms [59] found that the critical heat flux required to ignite Mahogany and oak samples with coated surfaces was considerably lower than that without them. Temperature The temperature of a fire is extremely important. The temperature of a flame can affect how quickly it burns as well as the amount of heat it generates. It can also influence how dangerous it is to be burned. It also affects how much smoke is generated. Smoke can cause irritation to eyes and throats, so it is recommended to not breathe it into. When wood burns, it creates plenty of heat and it can reach extremely high temperatures. The temperature of the fire will be affected by the type of wood used and the amount of moisture. Wet wood, like will burn at lower temperatures than dry wood. Wet wood absorbs more water, and thus produces less heat. It is important to use dry wood, and you should also make sure that the wood is well-seasoned prior to burning it. When the wood reaches its peak temperature of combustion it will release a lot of heat and ash. The amount of ash released will depend on the type of wood being burned and how hot it burns. Some woods such as oak and larch create very small amounts of ash. The Birch wood can produce a large amount of Ash. As the wood is burned it will go through three stages of Pyrolysis. This process starts with an chemical reaction that transforms organic compounds in the wood into methane and carbon dioxide. The gases that result are absorption by the air around. When the wood is heated the gases will rise and ignite the surface of the wood and create an ember that heats the wood until it combusts. The temperature of a fire that is wood burning can be very high, and it can damage surfaces if it comes into contact with them. Avoid touching the fire with your naked hands as it can cause serious burns. You can reduce your chance of burning by wearing a pair of gloves and working in a well-ventilated area. Masks are recommended when working with wood-burning fires to avoid breathing in smoke. Smoke Wood burning fires generate smoke which is a mixture of fine particles and gases (also called particulate matter or PM) that are harmful air pollutant. PM from wood combustion may contain harmful organic compounds, such as formaldehyde and benzene, as well as mineral particles like calcium, potassium and magnesium. The presence of these particles can lead to a range of health issues, including respiratory and cardiovascular diseases, as well as cancer. Inhaling smoke from wood can cause people to inhale CO, which is an odorless and colorless gas that is deadly in small doses. The smoke that is produced by wood fires is mostly due to volatile organic compounds (hydrocarbons) which evaporate from the burning material. The smoke is made up of water vapor, as well as by-products of incomplete burning (such as creosote) and the small amount of unburned material known as Ash. It is recommended to use seasoned wood in your fireplace or stove. Split logs, which have been stored out of the elements and allowed to dry for a period of time until they reach a moisture content of between 20 to 25 percent, will burn more slowly and produce less creosote. Knocking a log on both sides is a great method to determine the moisture content. A damp log will sound dull while seasoned wood will sound sharp. The smoke and other byproducts are released through the chimney. If the ventilation system in your home is not sufficient, the chimney may be insufficiently able to draw air and create a back draft, which could cause the byproducts of the fire to build up inside the home. This can result in the buildup of dangerous carbon monoxide as well as flammable creosote and cinders. Smoke from wood-burning fires could be particularly harmful to older people, those suffering from lung or heart conditions children, and outdoor enthusiasts. These people are more likely to suffer health issues from smoke from wildfires including COVID-19-related symptoms and aggravated asthma and chronic lung and heart conditions. Safety If you're using a wood burning fire, there are certain precautions that can be taken to minimize the risk of accidents and fire damage. For instance, you should always use a fireplace or wood stove screen and keep anything that is flammable at least three feet from it. Carbon monoxide and Smoke detectors should also be installed in your home to alert you when hazardous gases are detected. It is also essential to never leave a flame burning unattended, as even a tiny spark could cause an explosion. It is also recommended to use a metal ash bucket and a shovel to remove ashes from your wood stove or fireplace. Keep it away from anything flammable. Lighting the Fire To begin a fire, place the dry and broken logs on top of the ground with ash. Add a layer of twigs, kindling and ash to the pile. It is essential to leave enough space between the pieces of wood for airflow. This will help prevent the fire from dying too quickly. Add a few flames if you need some extra help to get your fire up and running. It's also an excellent idea to crack open a window as you begin to light your fire, because this will help the fire get the oxygen it needs to ignite brightly. This is especially important for modern homes that are typically sealed tight and do not have natural airflow or drafts. After your fire has gotten up, you can start adding more and larger pieces of wood to it. It is important to remember that even mature hardwoods like oak and hickory can produce a lot of creosote if they are burned. It is recommended to use kiln dried or seasoned firewood for burning your fire, as it will be less likely to create creosote in your chimney system. If you are forced to use fresh or green firewood, be very careful as it will produce more smoke and can lead to more creosote.
