Wood Burning Fires Need to Be Hot and Clean
Wood-burning fires aren't only relaxing and captivating They're also an essential part of our health and wellbeing. However, they must be clean and hot for them to function properly.
Green, or unseasoned, wood has high moisture content that makes it challenging to ignite and burn effectively. Kiln dried or seasoned wood has a lower moisture content, making it easier to ignite and maintain a flame.
Efficient Combustion
A wood fire needs to be hot enough to push out moisture and reach temperatures above 540 deg F ( The process of producing heat from secondary combustion begins at 900 degrees F (in ideal conditions). This is the most crucial step in efficiently burning the fuel while minimizing pollution smoke, creosote, and buildup in the flue.
It is crucial to remember that the temperature needed for secondary combustion varies with the type of fuel and the environmental conditions. The best method to reduce the variations is to use dry firewood that is seasoned and has an average moisture content of less than 20%.
The amount of air that is supplied to a fire will also have a significant impact on the energy output and time to burn. The more oxygen that is available, the more hot the fire will burn. When the air supply is not sufficient a wood fire produces less heat and will burn at a lower rate.
A wood stove or fireplace insert that has an adjustable air damper will increase burn time and efficiency. The wide-open setting allows the fire to get all the oxygen it needs and will quickly drain the fuel supply. A fire that is contained within a small space is less likely to spread.
A firewood pile that has been dried properly is crucial for efficient wood burning. Wood that is freshly cut and isn't dried will contain a lot of water, making it difficult to burn. It is recommended to use only well-seasoned firewood that has been stored outdoors for six to nine months to ensure optimal performance.
The BTU content of wood is another factor to consider. White pine and spruce could be more affordable than eastern hardwoods such as shagbark and hickory as well as black locust, but their BTU values are greater. This means they'll produce more heat from the same amount of wood. It is crucial to consider your heating needs and fuel costs when choosing your firewood.
Clean Burning
Wood smoke produces indoor air pollutants that irritate the lungs and can cause respiratory distress, particularly for seniors and children. cheap wood burner include volatile aromatic hydrocarbons (PAHs) like benzo-a pyrene and formaldehyde, as well as volatile organic compounds, such as benzene. When firewood is burned and smolders, volatile tars like creosote can also be released.
Smoke from older, poorly-designed fireplaces and wood stoves could contribute to poor outdoor air quality, reducing visibility and contributing to photochemical pollution. When used correctly however modern combustion technology in new clean-burning wood stoves and fire places can reduce these emissions.
Stage 1 - Vaporization of moisture: As the log gets warmer, it releases water vapour which escapes through the chimney flue. This uses up more energy than it would if the log was seasoned to dry before burning. This is a waste of energy which could be used to heat your home.
The vapors in the flue with carbon particles to produce smoke. Smoke is a major contributor to particulate matter in the air and is one of the main sources of smog that we experience on clear days.
Wood stoves and fireplaces with clean burn technology, if properly used, can greatly reduce the risk of this by burning the logs to a charcoal state that releases less volatile gasses, and creating the majority of the energy in the log from 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 thin and soft wood like pine or fir as it requires more energy to burn them, and they create more smoke which can cause chimney fires.
Use a bucket made of metal to remove ashes from the stove, and always wait for them to cool before handling them. Make sure you store or dispose of them in a safe manner since ashes could ignite if exposed to water, and they can be hazardous in landfills. Instead, ensure that you utilize them in your garden or around the house.
Storing, seasoning and properly burning your wood can help you save money and ensure your stove runs efficiently. cheap wood burning stoves is also crucial to regularly clean your chimney to remove deposited creosote and other particles and also to prevent chimney fires and maintain the safety of your operation.
Safety
It's difficult to beat a warm fire on a chilly winter night, but precautions for safety must be taken. When fires aren't properly built, burned or left unattended, harmful fumes could be released into the home and dangerous creosote deposits may build up inside the chimney. These deposits can clog the flue, inhibit the flow of air and cause your furnace or wood stove to run less efficiently.
Do not burn treated or painted trash in your wood-burning stove or fireplace. They emit noxious gasses and release toxic fumes like carbon monoxide. Don't use the flammable liquids to ignite fires. Gasoline, lighter fluid, and kerosene can cause chimney fires that can cause emissions to rise and produce toxic creosote.
Keep flammable materials like furniture, curtains, and even toys away from your fireplace or stove. Don't hang clothing close to or on your wood-burning fireplace. Make sure your children are aware that the fireplace is hot and should not be touched.
Only use seasoned wood in your fireplace or stove. Seasoned wood is dried through the summer to reduce moisture content. Wet woods produce more smoke and creosote. On the other hand, the wood that has been seasoned is more efficient and clear. Seasoned wood looks darker and has cracks in the end grain and is hollow when it is tapped. Store your wood outside, neatly stacked with the top covered, but allowing air circulation to them.
Be careful not to over-load your stove or fireplace, as overloaded appliances generate more smoke and produce less heat. Overloaded fires may also produce dangerous levels of carbon monoxide. If you own an older appliance that has a metal liner, check it frequently for signs of wear. This could cause an explosion in the chimney.
The EPA recommends reducing smoke inside your home by using dry, well-seasoned, split and dry wood and building a hot fire using small pieces. Avoid soft woods such as pine. Pine is a good fuel for a fire, but shouldn't be used for more than. These woods with softer sap contain and resin that, when burned, deposit excessive creosote in the chimney.
Maintenance
The warmth of a wood-burning fireplace is a wonderful option to relax during winter evenings. It is crucial 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 help you avoid any issues. This prevents the build-up of creosote and keeps the chimney clear for maximum efficiency.
Creosote is a dark, crusty flammable substance that forms in the flue when wood does not burn completely. 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. There are a variety of factors that can cause a fire to completely burn, including dampers that have not been properly closed or damaged in the chimney liner and a lack of regular cleaning and removal of ash.
Incorrectly seasoned wood contributes to an excessive buildup of creosote. This is because up to half of the weight of a piece wood is water. In the course of a fire the water boils and releases heat, but it also consumes energy during the process. The water vapor that is produced then condenses into creosote, or is released into the air as a part of smoke.
Soot is another harmful product of burning wood. Soot, though less dense than creosote can block airflow and stick to the walls. It is also a fire hazard because it can ignite easily when exposed to gasses that are combustible.
You should remove the ashes and place them in a metal ash bucket that you can keep outside on a nonflammable surface. The Ash can also be used as an energy source for plants Don't forget to spread them around the yard!
It is recommended that 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 two-stage chimney that includes an air tube the catalyst must be removed and checked visually for blockages. Refer to your user manual for directions on how to do this for the particular unit you have.
