Wood Burning Fires Need to Be Hot and Clean

The warmth and ambience of wood-burning fires are not just relaxing and captivating, but also essential to our health and well-being. They should be hot and clean to function.

Unseasoned, or green, wood has 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 ignite and keep a flame.

Efficient Combustion

A wood fire must be sufficiently hot to draw out moisture and reach temperatures of 540 deg F ( The process of producing heat in secondary combustion begins at 900 degrees F (in ideal conditions). This is the first step to efficiently burning fuel and minimizing emissions and smoke in the flue.

It is important to keep in mind that the temperature required for secondary combustion varies based on the type of fuel used and the conditions in the environment. Use seasoned firewood that has a moisture content of less than 20% to limit these variations.

The quantity of air being provided to a flame can also have a significant impact on the temperature and burning time. The more oxygen available, the hotter the fire will burn. A wood fire will generate 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 all the oxygen it needs and will quickly exhaust the fuel supply. A fire that is contained within a small space is less likely to spread.

A well-dried load of firewood is also crucial to efficient wood burning. When wood is cut just recently and hasn't had time to dry out, it will have high water content that could make it difficult for logs to burn. For the best performance it is recommended you only use seasoned wood that has been stored outside for six to nine months.

The BTU content of wood is a different factor to take into consideration. White pine and spruce could be cheaper than eastern hardwoods like shagbark, hickory and black locust, but their BTU values are higher. This means that they'll generate more heat for the same amount of wood. This is why it's crucial to think about your heating needs and fuel costs when selecting your firewood.

Clean Burning

Wood smoke produces indoor air pollutants that can irritate the lungs and cause respiratory distress, especially for older adults and children. These pollutants comprise volatile organic compounds (VOCs) like formaldehyde and benzene as well as polycyclic aromatic hydrocarbons such as benzo-apyrene, are carcinogenic. Volatile tars (such as creosote) are also released when firewood burns.

Smoke from poorly-designed wood stoves and fire places could cause poor air quality outside, reducing visibility and contributing photochemical smog. If used properly, however modern combustion technology in new clean-burning wood stoves and fire places can help reduce the emissions.

Stage 1 - Moisture vapourizes: As the log gets heated, it releases water vapor, which escapes through the chimney flue. This requires more energy than if the log had been dried before burning. This wastes energy which could be used to heat your home.

These vapors combine in the flue with carbon particles, resulting in smoke. Smoke is one of the major contributors to particulate matter in the air and is one of the main sources of smog we encounter on clear days.

When used correctly, wood stoves and fireplaces that use clean burn technology can reduce this problem significantly by converting the logs to charcoal-like conditions that releases less volatile gasses and releases most of the energy from the log into usable heat.

Avoid using damp or sour wood for your fire because it's more difficult to burn and generates much more creosote than well-seasoned wood. Do not overload your stove with soft and thin woods like pine or fir. They require more energy to burn and produce more smoke, which could cause chimney fires.

Always wait until the ashes have cooled before handling them. Dispose of or store the ashes properly. They could ignite again if exposed to water and can be dangerous to dispose of in landfills. Instead, ensure that you use them around your garden or in the home.

Storing, seasoning and correctly burning your wood can help you save money and keep your stove running efficiently. Cleaning your chimney regularly is essential to eliminate creosote and particulates as well as other debris that has been deposited. This can also help prevent chimney fires and ensure safe operation.

Safety

There's nothing like a warm fire to warm up chilly winter nights, but the right safety precautions are required. If fires are constructed incorrectly or left unattended, or if they are burned, dangerous fumes can enter the home. Creosote may also build up in the chimney. These deposits could block the flue, impede airflow, and cause your wood stove or furnace to operate less efficiently.

Never burn treated or painted trash in your wood-burning stove or fireplace. They produce noxious gases and can release toxic fumes like carbon monoxide. Avoid using liquids that are flammable as a starter. Gasoline, lighter fluid and kerosene could cause fires in chimneys, increase emissions, and create toxic creosote.

Keep combustibles, such as furniture curtains, toys, and other items at a safe distance from your fireplace or stove. Do not hang clothes on or near your wood-burning fireplace. Make sure your children know that the fire is hot and should not be touched.

Only use seasoned wood burning stoves small in your fireplace or stove. The wood that is seasoned has been dried through the summer to reduce moisture content. Wet woods produce more creosote and smoke, whereas seasoned logs burn much more efficiently and with less mess. Wood that is seasoned looks darker, has cracks in the end grain, and makes a hollow sound when tapped. Keep your logs outside stacked neatly, with the top covered, but allowing air to circulate around them.

Be aware not to over-load your fireplace or stove, as overloaded appliances generate more smoke and produce less heat. In addition, overloaded fires can produce unsafe carbon monoxide levels. If you own an older appliance that has an iron liner, you should inspect it regularly for signs of wear. This can lead to an explosion in the chimney.

The EPA suggests using dry, split and well-seasoned wood in order to reduce smoke in your home. Create a fire by using small pieces. Avoid soft woods such as pine. Pine is a great starting material for a fire, but shouldn't be used more than. These woods with softer sap contain and resin, which when burned, create large amounts of creosote into the chimney.

Maintenance

A warm fire in a wood-burning fireplace is a great method to relax during the cold nights of winter. It is important to maintain your fireplace in order to make the most of it. Regularly cleaning and inspecting your fireplace is the best way to avoid problems that may occur. This prevents the accumulation of creosote buildup, and also keeps the chimney clear to ensure maximum efficiency.

If wood doesn't completely burn and creosote builds up in the chimney. When a large amount of creosote builds up it can cause chimney fires. These are the second most common causes of house fires across the United States. The failure of a fire to burn completely can be caused by a variety of reasons including dampers that aren't properly closed and cracks in the chimney's liner, and a lack or regular cleaning and ash removal.

Creosote may build up excessively when wood is not properly prepared. This is because up to half of the weight of a piece of wood is water. When the fire is burning it boils and releases heat, but it also consumes energy during the process. The water vapor resulting from the process is then absorbed as creosote, or released into the atmosphere as part of the smoke.

Soot is another noxious product of burning wood. Soot, though less dense than creosote, can impede airflow and adhere to walls. It also poses an hazard to fire because it is a natural igniter when exposed to gases that are combustible.

It is recommended to remove the ashes and place them in a metal ash bucket that you keep outside on a non-flammable surface. The Ash can also be used as sources of nutrients for plants Don't forget to spread them around the backyard!

It is recommended to make sure that your chimney and fireplace are inspected by a Regency Dealer certified. The technician can check for cracks, creosote and soot levels as well as a properly shut damper and the condition of the catalyst. If you have a two-stage chimney that includes an air tube the catalyst must be removed and visually inspected for blockages. Consult your user's manual for instructions on how to do this for your particular unit.
