The Dangers of a Wood Burning Fire<br /><br />A wood burning fire can offer a warm and relaxing experience. It also produces toxic by-products of combustion. It is essential to know how wood burns, and how to use your fireplace properly.<br /><br />Choose the seasoned or kiln-dried logs. The logs that are seasoned have less moisture, and they can burn hotter and longer than unseasoned logs.<br /><br />Burning Time<br /><br />The burning of wood is a very effective and traditional method of heating. However, this fire can release outdoor and indoor emissions that can be dangerous to human health. Skillful use of a well-designed fireplace can help reduce the negative impacts of burning wood.<br /><br />The length of time that a wood fire lasts depends on how hot it is. The temperature of the fire can affect the quantity of smoke produced, as does the amount of carbon monoxide released. If carbon monoxide levels are high, they could hinder the escape of people from a burning building. To prevent this, it is important to keep the fire at a a low level of heat.<br /><br />In the beginning of a fire, volatile gasses such as alcohol and methane are released from the wood's cellulose. These gases are combustible as well as non-combustible, based on the moisture level and the pyrolysis temperature of the sample. The temperature of pyrolysis can rise to 325 degrees Celsius. At this point cellulose begins to decompose and create charcoal and tar. This process is called wood pyrolysis.<br /><br />Wood burning releases other harmful combustion products like dioxins, polyaromatic hydrocarbons, and PAHs. PAHs have been linked to cancer and other diseases in humans as well as in animals. They can also cause contamination of the soil and water. To reduce the effects of PAHs, wood must be burned in a properly ventilated space.<br /><br />A wood stove that has an extended burn capacity is able to maintain visible flames while using a minimal amount of fuel. This technique involves laying down wood with lighter kindling and larger pieces to prevent the fire burning out too fast. This technique can be used to create a the appearance of a fire that produces high heat for overnight use or even while at work.<br /><br />The time it takes to burn the wood fire is determined by several factors which include the moisture content of the wood. Dry wood will have a shorter burning time than damp wood. The absorptivity of the surface can also affect the duration of its burning. Simms [59] found that the critical heat flux required to ignite mahogany and oak samples was significantly lower on coated surfaces than without them.<br /><br />Temperature<br /><br />The temperature of the fire is critically crucial. It affects the speed at which it burns, and the heat that it generates. It can also influence the risk to get burned. It also influences the amount of smoke that is produced. If there is a lot of smoke, it may cause irritation to the eyes and throat and cause irritation, so it is recommended to be careful not to breathe it in.<br /><br />When wood burns, it releases plenty of heat and can reach high temperatures. The temperature of the fire can be affected by the type of wood and the moisture content. Wet wood, for example is likely to burn at less heat than dry wood. This is due to the fact that wet wood will absorb more water and less heat. It is crucial to use dry wood and you should ensure that the wood is seasoned before burning it.<br /><br />When the wood reaches its maximum temperature of combustion it will release a great deal of heat and ash. The amount of ash released will depend on the type of wood and the heat at which it is burning. Some woods, such as oak and larch, produce very little ash when they burn. <a href="https://www.fireplacesandstove.com/categories/wood-burning-stoves">indoor wood burning stove</a> , such as birch, can create an enormous amount of ash.<br /><br />As the wood burns it will go through three stages of pyrolysis. The process begins with an chemical reaction that transforms the organic compounds in the wood into methane and carbon dioxide. The gases produced are then taken up by the air. When the wood is heated, these gases will rise, and ignite the wood's surface, creating the appearance of a flame, which heats the wood until it combusts.<br /><br />The temperature of a fire that is wood burning can be extremely high and can cause damage to surfaces if it comes into contact with them. Avoid touching the fire with bare hands as it can cause serious burns. You can lessen the chance of burning by wearing gloves and working in a well-ventilated space. Also, it is recommended to wear a face mask when working with a wood burning fire to avoid inhaling smoke.<br /><br />Smoke<br /><br />Wood burning fires generate smoke, a mixture of gases and fine particles (also known as particulate matter, or PM) which contain harmful air pollutant. PM from wood combustion can contain harmful organic compounds such as formaldehyde, benzene, and polycyclic aromatic hydrocarbons and mineral particles such as calcium, potassium and magnesium. These particles can cause a variety of health problems such as respiratory and cancer. When people inhale wood smoke, they also inhale carbon monoxide (CO) which is an inert gas with no odor and color which can cause deadly poisoning in small doses.<br /><br />The smoke produced from a wood fire is largely due to volatile organic compounds (hydrocarbons) evaporating from the burning material. The smoke is a mixture of water vapor as well as the by-products of incomplete burning (such as creosote) and a small amount of unburned material called ash.<br /><br />It is best to make use of seasoned wood in your stove or fireplace. Logs that have been split, stored out of the weather and allowed to dry until they are seasoned (a moisture content of 20-25 percent) will burn less quickly and produce less creosote. A log's knock on both sides is an excellent way to determine the amount of moisture. The wood that is damp will make a sluggish sound, while mature logs will produce a sharp sound.<br /><br />While the heat generated by wood fire draws air from surrounding it, the smoke and other combustion byproducts are released through the chimney. If the home's ventilation system isn't adequate it could mean that the chimney is insufficiently able to draw air and create a back draft, which could cause the byproducts from the fire to accumulate within the house. This could lead to an accumulation of carbon monoxide as well in flammable creosote and cinders.<br /><br /><br /><br />Smoke from a wood-burning fireplace is particularly harmful to older people, those with heart or lung disease or children, as well as those who are active outdoors. Smoke from wildfires could be harmful to the health of older adults, people with heart or lung disease, children and those who exercise outdoors.<br /><br />Safety<br /><br />If you're using a wood burning fire, there are a few steps you can take to minimize the risk of fire-related accidents and damage. For example it is recommended to use a fireplace or wood stove screen and keep any flammable items at least 3 feet away from it. Additionally, you should have smoke and carbon monoxide detectors in your home, which will inform you if any dangerous gases are detected. It is not advisable to leave a fire unattended because even a small flame could cause an explosive explosion. Also, you should employ a metal shovel and ash bucket to remove the ashes from your fireplace or wood stove, and keep it far away from any flammable objects.<br /><br />Lighting the Fire<br /><br />To start a fire first put a layer of dry and broken logs on top of a bed of ash. Add a layer of twigs, kindling and ash to the pile. Make sure that there is enough space between each piece of wood to allow for air circulation, as this will prevent the fire from dying out too quickly. Add a few flames if you need some extra assistance to get your fire up and running.<br /><br />Open a window to let the fire breathe the oxygen it requires to burn brightly. This is especially crucial for modern homes that are typically sealed tight and have no natural ventilation or drafts.<br /><br />After the fire has established, you can add larger pieces of wood. It is important to keep in mind that even mature hardwoods like oak and hickory can produce a lot of creosote if they are burned.<br /><br />It is recommended to use seasoned or kiln dried wood when you are burning your fire, as it is less likely to create creosote in your chimney. If you are forced to use fresh or green firewood, be very careful as it will produce more smoke, which can result in more creosote.<br /><br />
