wood burning fires (my explanation) Need to Be Hot and Clean
Wood burning fires are not only comforting and mesmerising they're also a vital element of our health and wellbeing. But, they must be clean and hot for them to function properly.
Green wood, or unseasoned wood is characterized by an excessive amount of moisture, making it difficult to ignite and burn efficiently. Kiln dried or seasoned wood has a low moisture content, making it easier to ignite and keep a flame.
Efficient Combustion
The wood fire should be hot enough to burn off water and reach temperatures that exceed 540 degrees F. 900 degrees F in ideal conditions) where the heat-producing secondary combustion process begins. This is the primary step to efficient combustion of the fuel while minimizing pollution, smoke, and creosote accumulation in the flue.
It is important to note that the temperature needed for secondary combustion varies based on the type of fuel used and the conditions of the environment. The best method to reduce the variation is to use dry firewood that is seasoned and has less than 20%.
The quantity of air delivered to a fire can also have a significant influence on its temperature and burning time. The greater the oxygen supply, the hotter a fire can burn and the shorter its burn duration. If the supply of air is limited, however, a wood fire will produce less heat and will burn slower.
A fireplace or wood stove insert fitted with an adjustable air damper will increase the burn time and efficiency. Wide open settings allow the fire to burn through all oxygen available and quickly exhaust the supply of usable fuel. A fire that is contained in a small space is less likely to spread.
A firewood load that is well-dried is also vital for efficient wood burning. If wood is cut fresh and hasn't had the chance to dry out it will have a 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 outside for six to nine month.
Another thing to consider is the BTU content of different types of wood. For instance white pine or spruce wood may be less expensive than eastern hardwoods like shagbark hickory and black locust however, the BTU values of the latter are higher, which means they offer more heat for the same amount of wood. It is important to consider your heating needs and the cost of fuel when selecting your firewood.
Clean Burning
Wood smoke can trigger indoor air pollutants, which can cause irritation to lungs and respiratory discomfort in senior citizens and children. These pollutants include volatile aromatic hydrocarbons (PAHs) like benzo-a pyrene and formaldehyde and volatile organic compounds, such as benzene. Volatile tars (such as creosote) are also released when firewood is burned.
Smoke from poorly-designed wood burning stoves uk fireplaces and stoves can cause poor air quality outside, making it harder to see and causing photochemical pollution. However, new clean burning fireplaces and wood stoves with modern combustion technology, when used correctly can drastically reduce the emission.
Stage 1 - Moisture vapourizes: As the log gets heated, it releases water vapor which escapes through the chimney flue. This uses up more energy than if the log was seasoned to dry before burning. It also wastes energy that could be used for warming your home.
In the flue, these vapors mix with carbon particles to form smoke. Smoke is among the main sources of particulate matter and smog that is found in the air.
When used correctly wood burner stoves and fireplaces that utilize clean burn technology can reduce the risk of this issue by converting the logs to charcoal-like states that releases less volatile gasses and produces the majority of the energy produced by the log into usable heat.
Avoid using damp or sour wood to fuel your fire as it is more difficult to burn and generates a lot more creosote than well-seasoned corner wood burning stove. Do not overload your stove with thin and soft 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 are cool before handling them. Keep or dispose of ashes correctly. They can re-ignite when exposed to water and are dangerous to dispose of in landfills. Instead, make sure to use them around your garden or in the house.
Storing, seasoning and properly burning your wood can help you save money and ensure your stove runs efficiently. Regularly cleaning your chimney is important to remove creosote, particulates, and other deposited matter. This can also help prevent chimney fires and keep your chimney operating safely.
Safety
It's difficult to beat a warm fire on a cold winter night, but precautions for safety should be taken. When fires are built incorrectly and left unattended or burnt and a dangerous gas can be released into the home. Creosote may also build up in the chimney. These deposits could block the flue, block airflow and cause your wood stove or furnace to work less efficiently.
Never burn treated or painted waste in your wood-burning stove fireplace. They emit noxious gases and can release toxic fumes, like carbon monoxide. Avoid using flammable liquids as a fire starter. Gasoline, kerosene and lighter fluids can increase emissions, produce toxic creosote and possibly cause chimney fires.
Keep flammable materials like furniture, curtains and toys, a safe distance from your stove or fireplace. Never hang clothing on or near your wood burning fireplace. Children should be taught that the fireplace is extremely hot and shouldn't be touched.
Only use seasoned wood for your fireplace or stove. Seasoned wood has been dried throughout the summer to reduce the moisture content. Wet woods emit more smoke and creosote, whereas seasoned logs are more efficient and clean. Wood that is seasoned looks darker and cracks appear in the end grain, and is hollow when it is tapped. Keep your logs outside, neatly stacked and with the top partially covered but still allowing air circulation to them.
Appliances that are overloaded produce more smoke, but less warmth. Overloaded fires can also generate unsafe carbon monoxide levels. If you have an older appliance that has a metal liner, check it frequently for indications of wear. This can lead to an explosion in the chimney.
The EPA suggests reducing the amount of smoke in your home by using dry, split, and well-seasoned wood, and then constructing a warm fire with small pieces. Avoid using soft woods like pine. Pine is a great starting material for a fire, but shouldn't be used for more than. These softer woods have resin and sap that when burned, releases excessive creosote inside the chimney.
Maintenance
A warm flame in a wood burning fireplace is the perfect way to enjoy the cold winter nights. It is crucial to maintain your fireplace to ensure that you receive the maximum benefits from your fire. Regularly cleaning and inspecting your fireplace is the Best wood burning stoves method to avoid any issues that might occur. This prevents creosote buildup and keeps the chimney clean for maximum efficiency.
If wood doesn't completely burn, creosote forms in the chimney. If a significant amount of creosote is accumulated, it can cause chimney fires, which are the second-leading cause of house fires in the United States. A number of issues can cause a fire to completely burn, including dampers that are not properly sealed, cracks in the chimney liner and the absence of regular cleaning and the removal of ash.
Incorrectly seasoned wood contributes to an excessive buildup of creosote. This is because up to half the weight of a piece wood is water. When the fire is burning, this water boils and releases heat but it also consumes energy in the process. The water vapor resulting from the process is then absorbed as creosote, or released into the air as part of the smoke.
Another hazard of burning wood is soot. Soot is less brittle than creosote, however it can cling to the walls of your fireplace, and block air circulation. It could also pose an ignition risk since it can ignite easily when exposed to gasses that are combustible.
The ashes should be removed and put them in a metal ash bucket, which you should keep outside on a nonflammable surface. The ashes can also be used as sources of nutrients for plants So don't forget to spread them out across the yard!
It is recommended to ensure that your chimney and fireplace are examined by a Regency Dealer certified. The technician can check for cracks in the chimney, soot and creosote levels, a properly shut damper and the condition of your catalyst. If you have a double-stage fireplace that has an air tube, you must remove the catalyst and visually checked for any blockages. Refer to your user manual for instructions on how to accomplish this for the particular unit you have.
