Wood Burning Fires Need to Be Hot and Clean
Wood-burning fires aren't only relaxing and captivating, but they're a critical element of our health and well-being. They should be hot and clean in order to function.
Green wood, also known as unseasoned wood has a high moisture content which makes it difficult to ignite and burn efficiently. Kiln dried or seasoned wood has a low moisture content, making it easier to ignite and maintain a fire.
Efficient Combustion
A wood fire must be hot enough to push out water and reach temperatures that are above 540 degrees F ( The process of producing heat in secondary combustion begins at around 900 degrees F (in ideal conditions). This is the most important step to efficient combustion of the fuel and reducing pollutants, smoke, and creosote accumulation in the flue.
It is crucial to remember that the temperature needed for secondary combustion is dependent on the type of fuel used and the environmental conditions. The best method to reduce these variations is by using well-seasoned firewood that has less than 20 percent.
The quantity of air that is provided to a flame will also have a significant impact on its energy output and time to burn. The higher the amount of oxygen available, the hotter a fire will burn and the shorter its burn duration. A wood fire will produce less energy and burn at a slower rate when the air supply is restricted.
To ensure maximum burn time and efficiency, a wood stove or fireplace insert must be equipped with an adjustable air damper. The wide-open setting lets the fire to take all the oxygen it needs and quickly drain the fuel supply. The converse is true of a fire that is confined to a smaller area where the fire is unable to expand as much.
A dry load of firewood is also critical to efficient wood burning. If wood is cut fresh and hasn't had the chance to dry, it will have high water content, which could make it difficult for logs to burn. For the best performance, it is recommended that you use only seasoned wood that has been stored outdoors for six to nine month.
The BTU content of wood is another factor to take into consideration. For example, white pine or spruce trees might be cheaper than eastern hardwoods, such as black locust and shagbark hickory, however, the BTU values of the latter are much higher, which means they offer more heat for the same amount of wood. This is why it's crucial to take into consideration your heating requirements and fuel costs when selecting your firewood.
Clean Burning
Wood smoke is a source of indoor air pollutants that irritate the lungs and can cause respiratory distress, especially for children and seniors. These pollutants include volatile organic compounds (VOCs) like formaldehyde and benzene, as well as polycyclic aromatic hydrocarbons like benzo-a-pyrene, that are carcinogenic. Volatile tars (such as creosote) are also released when firewood burns.
Smoke from old, poorly designed fireplaces and wood stoves can contribute to poor outdoor air quality by making it harder to see and contributing to photochemical pollution. If used properly, however modern combustion technology in new wood stoves that burn clean and in fire places can help reduce the emissions.
Stage 1 - Moisture Vaporizes As the log gets heated, it releases water vapor that escapes down the chimney flue. This is more energy-intensive than it would have when the log was dried to dry before burning. This is a waste of energy which could be used to warm your home.
These vapors mix in the flue with carbon particles to create smoke. Smoke is a major contributor to particulate matter in the air and is among the main sources of smog that we experience on clear days.
Fireplaces and wood stoves equipped with clean burn technology, if utilized correctly, can dramatically reduce the risk of this by converting the logs into a charcoal state which releases much less volatile gasses, and creating the majority of the energy contained in the log from usable heat.
Avoid using damp or sour wood for your fire because it's more difficult to burn and creates lots of creosote compared to well-seasoned wood. Also, don't overburden your stove with thin and soft wood such as fir or pine It takes more energy to burn them, and they create more smoke which can cause chimney fires.
Always wait until the ashes have cool before handling them. Keep or dispose of the ashes properly. They could ignite again if exposed to water and can be dangerous in landfills. Use them in your garden or at home.
Storing, seasoning and properly burning your wood will help you save money and ensure that your stove is operating efficiently. It is also essential to regularly clean your chimney to get rid of creosote and particulate matter as well as to avoid chimney fires and maintain the safety of your operation.
Safety
There's nothing like a cozy fire to keep warm during cold winter evenings, however proper safety precautions are required. If fires are not constructed correctly or left unattended, or if they are burned, dangerous fumes can enter the home. Creosote can also build up in the chimney. These deposits could block the flue and decrease airflow, causing your furnace or wood stove to not work as efficiently.
Do not burn treated or painted garbage in your wood-burning stove or fireplace. They can release toxic fumes like carbon dioxide and produce toxic gases. Also, do not use flammable liquids to start fires. Gasoline, lighter fluid and kerosene can cause fires in chimneys, increase emissions, and cause toxic creosote.
Keep flammable materials, such as furniture, curtains and toys, a safe distance from your fireplace or stove. Do not hang clothes near or on your fireplace with wood burning. Make sure your children are aware that the fire is hot and should not be touched.
Only make use of seasoned wood for your stove or fireplace. The wood that is seasoned has been dried over the summer months to reduce the moisture. Wet woods produce more smoke and creosote, whereas mature logs are more efficient and cleaner. Seasoned wood looks darker, has cracks in the end grain, and is hollow when tapping. Keep your logs outside stacked neatly, with the top covered, but allowing air to circulate around them.
Overloaded appliances produce more smoke, but less warmth. In addition, overloaded fires can produce unsafe carbon monoxide levels. If you have an older appliance that has an iron liner, you should inspect it regularly for signs of wear. This could cause an explosion in the chimney.
The EPA recommends using dry, split and well-seasoned wood in order to minimize the amount of smoke that your home produces. Create a fire by using small pieces. Avoid using softer woods like pine, which are a great for starting your fire going, but should not be used for more than that. These softer woods have sap and resin which is a result of burning, and deposits excessive creosote into the chimney.
Maintenance
Warming up in front of a fireplace that is wood-burning is a great way to enjoy the winter evenings. It is crucial to maintain your fireplace in order to ensure that you get the most benefits from your fire. Regularly cleaning and inspecting your fireplace is the best way to prevent problems that could arise. This prevents the build-up of creosote and keeps the chimney clear for maximum efficiency.
Creosote, a dark, crusty flammable material that forms in the flue when wood does not burn completely. When a large amount of creosote builds up it can cause chimney fires. These are the second leading causes of house fires across the United States. The failure of a fireplace to completely burn can be caused by a variety of factors, including improperly closed dampers or cracks in the chimney's liner as well as a lack of regular cleaning and ash removal.
Creosote can build up in large amounts when wood isn't properly prepared. Water could comprise up to half of the weight of a wooden piece. During the fire, this water boils and releases heat, but it also consumes energy in the process. The water vapor produced then condenses into creosote, or is released into the air as a part of smoke.
corner wood burner of burning wood is soot. Soot, although less dense than creosote, can impede airflow and stick to the walls. It is also a fire hazard because it is a natural igniter when exposed to combustible gases.
The ashes should be removed and store them in an ash bucket made of metal, which you should keep outside on a non-flammable surface. The ashes can also be used as sources of nutrients for plants, so don't forget to spread them out across the backyard!
You should have a Certified Regency Dealer inspect your chimney and fireplace regularly. The technician can check for cracks, creosote and soot levels, a properly shut damper and the condition of the catalyst. If you have a double-stage fireplace with an air tube, it is recommended to remove the catalyst and visually inspected for any blockages. Check your user manual for directions on how to do this for your particular unit.
