Wood Burning Fires Need to Be Hot and Clean
Wood burning fires are not only relaxing and captivating They're also an essential element of our health and well-being. They should be hot and clean to work.
Unseasoned, wood burning fires or green, wood has a high moisture content which makes it difficult to ignite and burn effectively. Kiln dried or seasoned wood has a low moisture content, making it easier to light and keep a flame.
Efficient Combustion
The wood fire should be hot enough to snuff out moisture and reach temperatures of over 540 degrees F. 900 degrees F in ideal conditions) where the heat-producing secondary combustion process starts. This is the most crucial step in efficient combustion of the fuel and minimizing pollutants, smoke, and creosote buildup in the flue.
It is crucial to understand that the temperature required to ignite the secondary combustion process is dependent on the type of fuel used and the surrounding conditions. The best way to limit the variations is to use well-seasoned firewood that has a moisture content below 20 percent.
In addition, the quantity of air supplied to the fire can have a significant impact on its heat output and time to burn. The more oxygen available the hotter a fire can burn and the shorter its burn duration. When the air supply is not sufficient a wood fire will produce less heat and burn at a slower rate.
A wood stove or fireplace insert with an adjustable air damper can increase the time to burn and efficiency. The wide-open setting allows the fire to get all the oxygen it needs and quickly exhaust the fuel supply. The reverse is true for an area that is limited to a limited area, where the fire is unable to expand as much.
A load of firewood that is well-dried is also essential for efficient wood burning. If wood is cut fresh and hasn't had a chance to dry out it will have a high levels of water, which may 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.
Another thing to consider is the BTU content of various types of wood burning stove in conservatory. For example, white pine or spruce trees might be cheaper than eastern hardwoods like shagbark hickory and black locust but the BTU values of the latter are much higher, meaning they will offer more heat for the same amount of wood burned. This is why it's crucial to think about your heating needs and the fuel costs when selecting your firewood.
Clean Burning
Wood smoke can trigger indoor air pollution that can irritate lungs and cause respiratory discomfort in senior citizens and children. These pollutants include volatile aromatic hydrocarbons (PAHs) such as benzo-a-pyrene and formaldehyde, as well as volatile organic compounds, such as benzene. Volatile tars (such as creosote) are also released when firewood burns.
Smoke from older, poorly-designed fireplaces and wood stoves can contribute to poor outdoor air quality by decreasing visibility and causing photochemical smog. If used properly, however modern wood burner technology for combustion in clean-burning wood woodburning stoves and places can help reduce the emissions.
Stage 1 - Moisture Vaporizes As the log heats up it releases water vapor, that escapes down the chimney flue. This is more energy-intensive than 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 one of the major sources of particulate matter and smog in the air.
Fireplaces and wood stoves equipped with clean burn technology, when used correctly, can significantly reduce this issue by burning the logs to a charcoal state which releases much less volatile gasses, and producing most of the energy contained in the log from usable heat.
Avoid using damp or sour wood for your fire - it's more difficult to burn and creates much more creosote than well-seasoned wood. Do not overload your stove with brittle and thin woods such as fir or pine. They require more energy to burn and create more smoke, which could cause chimney fires.
Always wait until the ashes have cooled before handling them. Be sure to store or dispose of them properly as ashes can ignite if exposed to water, and they can be hazardous in landfills. Instead, make sure to use them around your garden or around the house.
Properly conserving, securing and burning your wood will save you money on fuel and will keep your stove running efficiently. Cleaning your chimney on a regular basis is essential to eliminate creosote and particulates as well as other deposited matter. This can also stop chimney fires and keep your chimney operating safely.
Safety
It's hard to beat a warm fireplace on a cold winter night however, precautions for safety must be taken. When fires aren't properly built, burned or left unattended, dangerous fumes can escape into the house and creosote deposits can build up inside the chimney. These deposits can block the flue, impede airflow, and cause your furnace or wood stove to work less efficiently.
Never burn painted or treated wood, household garbage, rags, paper and other combustible materials inside your wood-burning stove or fireplace. They emit noxious gases and can release toxic fumes, such as carbon monoxide. Avoid using flammable liquids as a fire starter. Gasoline, lighter fluid and kerosene may cause fires in chimneys that can cause emissions to rise and create toxic creosote.
Keep combustibles, like furniture or curtains, as well as toys, in a safe distance from your fireplace or stove. Never hang clothing on or near your fireplace that is wood burning. Make sure your children are aware that the fire is hot and should not be touched.
Only use seasoned wood for your stove or fireplace. Seasoned wood has been dried during the summer months to decrease the moisture content. Woods that are damp emit more smoke and creosote. On the other hand, the wood that has been seasoned is more efficient and clean. The wood that is seasoned is darker and has cracks along the end grain and sounds hollow when you tap it. Keep your logs outside stacked neatly with the top covered and allowing air to circulate around them.
The appliances that are overloaded generate more smoke, but less warmth. Overloaded fires can also generate unsafe carbon monoxide levels. If you have an older appliance with an iron liner, you should inspect it frequently for indications of wear. This can lead to an explosion in the chimney.
The EPA recommends reducing smoke in your home by using dry, split and well-seasoned wood, and then constructing a warm fire with small pieces. Avoid soft woods such as pine. Pine is a great starting material for an open flame, but should not be used beyond that. These soft woods are brimming with sap and resin, which when burned, create an excessive amount of creosote in the chimney.
Maintenance
A warm fire in a wood-burning fireplace is the perfect way to enjoy the cold winter nights. It is crucial to maintain the fireplace to make the most of it. Regular inspections and cleaning of your fireplace will allow you avoid any issues. This maintenance prevents excessive creosote and keeps the chimney clean for maximum efficiency.
When wood doesn't burn completely it forms creosote in the chimney. If a substantial amount of creosote builds up it can trigger chimney fires, which are the second hand wood burner most common cause of house fires in the United States. There are a variety of factors that can cause a fire to fail to burn completely, including dampers that have not been properly closed and cracks in the chimney liner and a lack of regular cleaning and removal of ash.
Creosote can build up excessively when wood is not properly treated. Water can make up half of the weight of a wood piece. During the fire the water boils and releases heat, but it also consumes energy in the process. The resulting water vapor is then absorbed as creosote, or released into the atmosphere as part of the smoke.
Soot is a different harmful byproduct from burning wood. Soot, though less dense than creosote, is able to block airflow and stick to walls. It can also be a fire hazard because it is easily ignited when exposed to combustible gasses.
The ashes should be removed and place them in a metal ash container that you can keep outside on a nonflammable surface. Don't forget that the dust is a fantastic source of nutrients for your plants. Spread them out in your backyard!
You should have a Certified Regency Dealer inspect your chimney and fireplace regularly. The technician will look for cracks, creosote levels, soot levels and a damper that is shut properly 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 obstructions. Check your user's manual to find out the procedure for your fireplace.
