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 need to be warm and clean in order to work.
Green wood, also known as unseasoned wood, has a high moisture content, making it difficult to ignite and burn effectively. The seasoned, or kiln dried wood has a low moisture content and is therefore easier to light and keep burning.
Efficient Combustion
A wood fire must be hot enough to push out moisture and reach temperatures above 540 deg F ( 900 deg F in ideal conditions) at which the secondary combustion process begins. This is the most crucial step in efficiently burning the fuel and reducing pollutants, smoke, and creosote buildup in the flue.
wood burning fireplace is crucial to understand that the temperature needed for secondary combustion depends on the type of fuel used and the conditions around it. The best way to minimize the variations is to use well-seasoned firewood that has an average moisture content of less than 20 percent.
The quantity of air provided to a flame will also have an important impact on its temperature and burning time. The more oxygen available, the more hot the fire will burn. A wood fire will produce less energy and burn at a slower rate when the air supply is limited.
To increase the time of burning and efficiency to maximize efficiency and burn time, a wood stove fireplace insert must be equipped with an adjustable air damper. The wide-open setting gives the fire to take all the oxygen it needs and will quickly draw down the fuel supply. A fire that is contained in an area of limited size is less likely to spread.
A load of firewood that is well-dried is also vital for efficient wood burning. Freshly cut wood that isn't dried will have a high water content which makes it difficult to burn. It is recommended to only use wood that is seasoned and has been stored outdoors for between six and nine months for optimal performance.
Another factor to consider is the BTU content of different kinds of wood. For instance, white pine or spruce wood may be less expensive than eastern hardwoods such as shagbark hickory and black locust however the BTU values of the latter are much higher, which means they provide more heat for the same amount of wood burned. This is why it's important to take into consideration your heating requirements and the cost of fuel when choosing your firewood.
Clean Burning
Wood smoke can cause indoor air pollution, which can irritate lungs and cause respiratory discomfort in senior citizens and children. These pollutants include volatile organic compounds (VOCs) such as formaldehyde and benzene, as well as polycyclic aromatic hydrocarbons such as benzo-apyrene, can cause cancer. When firewood is smuggled into the air the volatile tars like creosote are also released.
Smoke from poorly designed wood stoves and fire places can cause poor air quality outside by decreasing visibility and causing photochemical pollution. However, new clean burning wood stoves and fireplaces equipped with modern technology for combustion, when used correctly can significantly reduce the emissions.
Stage 1 - Moisture Vaporizes: As the log heats up it releases water vapor which escapes up the chimney flue. This takes more energy than when the log was dried prior to burning. This is a waste of energy that could be used to warm your home.
In the flue, these vapors combine with carbon particles and form smoke. Smoke is one of the major contributors to particulate matter in the air and is among the main sources of smog that we see on clear days.
When used correctly when used correctly, wood stoves and fireplaces that use clean burn technology can reduce the problem by converting the logs to charcoal-like conditions that releases less volatile gasses and releases most of the energy from the logs as usable heat.
Avoid using damp or sour wood for your fire - it's more difficult to burn and creates lots of creosote compared to well-seasoned wood. Also, don't overload 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 lead to chimney fires.
Use a bucket made of steel to scoop ashes from the stove, and always wait for them to cool before handling them. Keep or dispose of ashes in a safe manner. They can re-ignite when exposed to water and are dangerous to dispose of in landfills. Instead, ensure that you use them around your garden or around the house.
Properly conserving, securing and burning your wood will save you money on fuel and ensure that your stove is running efficiently. It is also crucial to clean your chimney regularly to remove deposited creosote and particulate matter, as well as prevent chimney fires and maintain the safety of your operation.
Safety
There's nothing like a cozy fire to warm up chilly winter evenings, however proper safety precautions are necessary. When fires are built incorrectly or left unattended, or if they are burned, dangerous fumes can enter the home. Creosote also builds up in the chimney. These deposits could block the flue, inhibit the flow of air and cause your wood stove or furnace to work less efficiently.
Never burn painted or treated wood, household waste paper, rags, and other combustible materials inside your wood-burning stove or fireplace. They emit noxious gases and can release toxic fumes, like carbon monoxide. Also, do not use the flammable liquids to ignite fires. Gasoline, lighter fluid, and kerosene can cause fires in chimneys, increase emissions, and cause toxic creosote.
Keep combustibles such as furniture curtains, toys, and other items in 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 hot and should not be touched.
Make sure to use only wood that has been seasoned for your fireplace or stove. Seasoned wood is dried throughout the summer to decrease the moisture content. Wet woods produce more smoke and creosote while seasoned logs burn more efficiently and with less mess. The wood that is seasoned appears darker, has cracks in the end grain and is hollow when tapping. Place your logs outdoors and stack them neatly with the top covered and allowing air to circulate around them.
Be cautious not to overload your stove or fireplace because overloaded appliances produce more smoke and less heat. In addition, overloaded fires can produce dangerous levels of carbon monoxide. If you own an older appliance with an aluminum liner, be sure to check it frequently for indications of wear. This could cause a chimney fire.
The EPA suggests reducing the amount of smoke in your home by using dry, split, and well-seasoned wood and building a hot fire with small pieces. Avoid using soft woods such as pine, which are good starting material to get your fire up and running but should not be used for anything other than. These softer woods have sap and resin which, when burnt, deposits excessive creosote into the chimney.
Maintenance
The warmth of a wood-burning fireplace is a wonderful way to spend winter nights. It is important to maintain your fireplace in order to get the most enjoyment of it. Regular inspections and cleaning of your fireplace will allow you to avoid any problems. This prevents creosote buildup and helps keep the chimney clean to ensure maximum efficiency.
Creosote, a dark, crusty flammable substance that forms in the flue when wood does not completely burn. When a lot of creosote accumulates, it can lead to chimney fires. They are the second leading cause of house fires across the United States. The inability of a fire to fully burn is caused by a number of reasons, including improperly closed dampers or cracks in the liner of the chimney, and a lack or regular cleaning and removal of ash.
Creosote can accumulate excessively when wood is not properly treated. This is because nearly half the weight of a piece of wood is water. In the course of a fire it boils and releases heat, but it also consumes energy during the process. The resulting water vapor is then absorbed as creosote or released into the atmosphere as part of the smoke.
Soot is another harmful byproduct of burning wood. Soot, while softer than creosote, can impede airflow and stick to walls. It also poses an ignition hazard since it easily ignites when exposed to gases that are combustible.
It is recommended to remove the ashes and put them in a metal ash bucket that you keep outside on a non-flammable surface. Don't forget that remains of the ashes are a good source of nutrients for your plants. Spread them out in your yard!
Make sure you ensure 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 should be removed and visually checked for obstructions. Check your user's manual to learn how to do this for your particular unit.
