Wood Burning Fires Need to Be Hot and Clean The warmth and ambience of wood-burning fires is not just relaxing and captivating but is also vital to our health and well-being. They must be hot and clean in order to function. Green wood, or unseasoned wood is characterized by 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 much easier to light and maintain a fire. Efficient Combustion The wood fire should be hot enough to snuff out water and reach temperatures that exceed 540 degrees F. 800 deg F in ideal conditions) in ideal conditions) where the secondary combustion process starts. This is the key step in efficient combustion of fuel and minimizing pollutants and smoke in the flue. It is crucial to remember that the temperature required for secondary combustion is dependent on the type of fuel and the conditions of the environment. Choose firewood that is well-seasoned and has an average moisture content of less than 20% to minimize these variations. The quantity of air that is delivered to a fire will also have a significant impact on the heat output and burning time. The greater the oxygen supply, the more hot a fire will burn and the shorter its burn duration. When the air supply is insufficient a wood fire will produce less heat and burn at a lower rate. A fireplace or wood stove insert with an adjustable air damper will maximize burn time and efficiency. A wide open setting allows the fire to use up all oxygen available and quickly exhaust the fuel available for use. This is not the case with a fire that is confined to a smaller area where the fire can not expand as much. A firewood pile that has been properly dried is crucial for efficient wood burning. Wood that isn't dried will contain high levels of water, making it difficult to burn. It is recommended to use only well-seasoned firewood that has been stored outdoors for a period of six to nine months to ensure optimal performance. Another factor to consider is the BTU content of various types of wood. For instance, white pine or spruce trees might be cheaper than eastern hardwoods, such as shagbark hickory and black locust however the BTU values of the latter are more, meaning they offer more heat for the same amount of wood. This is why it's crucial to think about your heating needs and the cost of fuel when choosing your firewood. Clean Burning Wood smoke is a source of indoor air pollutants that irritate the lungs and can cause respiratory distress, particularly for children and seniors. These pollutants include volatile organic compounds (VOCs) such as benzene and formaldehyde, and polycyclic aromatic hydrocarbons, like benzo-a-pyrene, that can cause cancer. Volatile Tars (such as creosote) are also released when firewood burns. Smoke from poorly-designed wood stoves and fire places could contribute to poor air quality outside by making it harder to see and causing photochemical pollution. However, new clean burning fireplaces and wood stoves equipped with modern technology for combustion, when used correctly can significantly reduce the emission. Stage 1 - The vaporization of Moisture: As the log heats, it releases water vapour that escapes through the chimney flue. This is more energy-intensive than if the log was dried prior to burning. This also wastes energy that could be put to use to heat your home. These vapors combine in the flue with carbon particles to produce smoke. Smoke is one of the major sources of particulate matter and smog in the air. When used correctly, wood stoves and fireplaces using clean burn technology can reduce the risk of this issue by burning the logs into charcoal-like conditions, which releases less volatile gasses and produces most of the energy from the logs as usable heat. Avoid using damp, sour or rotten wood to ignite your fire. It's more difficult to burn and creates more creosote. Don't over-load your stove with soft and thin wood such as fir or pine as it requires more energy to burn them, and they also produce more smoke that can cause chimney fires. Always wait until the ashes have cooled before handling them. Make sure you store or dispose of them in a safe manner since ashes could ignite when exposed to water, and they can be hazardous in landfills. Make use of them in your garden or at home. Properly conserving, securing and burning your wood properly will save you money on fuel and will keep your stove running efficiently. It is also important to clean your chimney regularly to get rid of creosote and particles and also to prevent chimney fires and maintain the safety of the operation. Safety There's nothing better than a warm fire to keep warm during cold winter nights, but the right safety precautions are necessary. If fires are not properly constructed, burned or left unattended, dangerous fumes can be released into the house and creosote deposits may build up within the chimney. These deposits can clog the flue, block airflow, and cause your wood stove or furnace to work less efficiently. Do not burn treated, painted, or household waste in your wood-burning stove fireplace. They produce noxious gases and may release toxic fumes, like carbon monoxide. Do not use liquids that are flammable as a starter. Gasoline, kerosene and lighter fluid can increase emissions, create toxic creosote, and even cause chimney fires. Keep combustibles such as furniture or curtains, as well as toys, at a safe distance away from your fireplace or stove. Never hang clothing on or near your wood burning fireplace. Children should be taught that the fireplace is very hot and should not be touched. Only use seasoned wood for your fireplace or stove. The wood that is seasoned has been dried over the summer months to lessen the amount of moisture. Wet woods produce more smoke and creosote while seasoned logs burn more cleanly and more efficiently. Seasoned wood looks darker and has cracks in the end grain and sounds hollow when tapped. Place your logs outdoors and stack them neatly, with the top covered with a breathable air circulate around them. wood burning stoves uk that are overloaded generate more smoke and less warmth. In addition, overloaded fires can produce dangerous levels of carbon monoxide. If you own an older appliance that has a metal liner, check it regularly for signs of wear. This could lead to an explosion in the chimney. The EPA recommends using split, dry and well-seasoned wood to reduce smoke in your home. Create a fire by using small pieces. Avoid using soft woods like pine, which can be a good starter material to get your fire up and running however should not be used for anything more than. These soft woods contain sap and resin which is a result of burning, and deposits too much creosote in the chimney. Maintenance The warmth of a wood-burning fireplace is a great option to relax during winter nights. However, it is important to maintain your fireplace in order to ensure that you receive the maximum enjoyment from your fireplace. Regular inspections and cleaning of your fireplace will allow you avoid any issues. This prevents the accumulation of creosote accumulation and ensures that the chimney is clean for maximum efficiency. Creosote is a dark, crusty flammable substance that forms in the flue when wood does not completely burn. If a significant amount of creosote is accumulated, it can trigger chimney fires, which are the second leading cause of house fires in the United States. A variety of issues could cause a fire to fail to burn completely, including dampers that are improperly closed or damaged in the chimney liner and the absence of regular cleaning and removal of ash. Incorrectly seasoned wood causes an excessive buildup of creosote. Water can make up half of the weight of a wooden piece. The water is heated during the fire and releases heat. It also consumes energy. The water vapor resulting from the process is then condensed into creosote, or released into the air as part of the smoke. Another hazard of burning wood is soot. Soot, while softer than creosote, is able to block airflow and stick to walls. It can also be an ignition risk since it can ignite easily when exposed to combustible gases. Remove the ashes from your fireplace and store them in an ash bucket made from metal. Keep it outside on a non-flammable area. Don't forget that the ashes are a great source of nutrients for your plants. Spread them out in your yard! Make sure you ensure that your chimney and fireplace are checked by a Regency Dealer Certified. The technician will be able to look for cracks in the chimney, soot and creosote levels, a properly sealed damper and the condition of your catalyst. If you have a two-stage chimney that includes an air tube, the catalyst must be removed and visually inspected for obstructions. Consult your user manual to learn how to do it for your particular unit.
