Wood Burning Fires Need to Be Hot and Clean
The warmth and ambience of wood-burning fires are not just soothing and enchanting, but also essential to our health and well-being. However, they must be hot and clean for them to function properly.
Green, or unseasoned wood has a high moisture content that makes it challenging to light and burn efficiently. Kiln dried or seasoned wood has a low moisture content, making it easier to ignite and maintain a flame.
Efficient Combustion
The wood fire should be sufficiently hot to eliminate moisture and reach temperatures over 540 degrees F. 900 degrees F in ideal conditions) at which the secondary combustion process begins. This is the primary step to efficient combustion of the fuel and reducing pollutants, smoke, and creosote accumulation in the flue.
It is crucial to remember that the temperature needed for secondary combustion varies with the type of fuel and the conditions in the environment. Make sure to use firewood that is seasoned and has a a moisture content of less than 20% to limit the variations.
The amount of air provided to a flame can also have a significant impact on the heat output and burning time. The more oxygen that is available, the hotter the fire will burn. If the supply of air is insufficient, a wood fire produces less heat and burn slower.
To increase the time of burning and efficiency To maximize the efficiency and time of burn, a wood stove or fireplace insert should be fitted with an adjustable air damper. The wide-open setting allows the fire to take all the oxygen it can get and will quickly drain the fuel supply. A fire that is contained in the confines of a small area is less likely to spread.
A well-dried firewood load is also essential to 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 may make 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.
Another consideration is the BTU content of different types of wood. White pine and spruce might be more affordable than eastern hardwoods such as shagbark, hickory and black locust, however their BTU numbers are higher. This means that they'll produce more heat with the same amount of wood. This is why it's crucial to consider your heating requirements and the cost of fuel when choosing your firewood.
Clean Burning
Wood smoke produces indoor air pollutants that irritate the lungs and cause respiratory distress, particularly for children and seniors. These pollutants include volatile aromatic hydrocarbons (PAHs) like benzo-a pyrene and formaldehyde and volatile organic compounds like benzene. 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 by reducing visibility and contributing photochemical smog. When used correctly however modern wood burner combustion technology in new clean-burning wood stoves and fire places can help reduce the emissions.
Stage 1 - Moisture Vaporizes As the log heats up, it releases water vapor that escapes down the chimney flue. This takes more energy than if the log was dried prior to burning. It also consumes energy that could be put to use warming your home.
In the flue, the vapors mix with carbon particles to form smoke. Smoke is one of the major sources of particulate matter and smog that is found in the air.
Fireplaces and wood stoves that use clean burn technology, when properly used, can greatly reduce this problem by burning the logs to the state of charcoal, which releases far less volatile gases, as well as producing the majority of the energy contained in the log from usable heat.
Avoid using damp, sour or decayed wood to light your fire. It is more difficult to burn and generates more creosote. Also, don't overload your stove with soft and thin wood such as fir or pine; it takes more energy to burn them and they also produce more smoke that can cause chimney fires.
Always wait until the ashes are cool before handling them. Make sure you store or dispose of them correctly since ashes could ignite when exposed to water, and they can be hazardous in landfills. Use them in your garden or at home instead.
Properly properly storing, seasoning and burning your wood properly will save you money on fuel and keep your stove running efficiently. Regularly cleaning your chimney is crucial to get rid of creosote, particulates and other deposited matter. This will also prevent chimney fires and maintain safe operation.
Safety
There's nothing like a warm fire to warm up chilly winter evenings, but proper safety precautions are required. When fires are built incorrectly, left unattended or burned, dangerous fumes can enter the home. Creosote also builds up in the chimney. These deposits can clog up the chimney and restrict the flow of air, making your wood burning stoves small wood burner (linked website) stove or furnace not to function as efficiently.
Never burn treated or painted wood, household trash, rags, paper and other combustible substances in your wood-burning stove or fireplace. They release toxic fumes such as carbon dioxide and produce toxic gases. Also, do not use flammable liquids to start fires. Gasoline, lighter fluid and kerosene can cause chimney fires that can cause emissions to rise and produce toxic creosote.
Keep combustible materials like furniture, curtains, and even toys away from your stove or fireplace. Never hang clothing near or on your fireplace with wood burning. Children should be taught that the fireplace is hot and shouldn't be touched.
Only use seasoned freestanding wood burner in your fireplace or stove. The wood that has been seasoned has been dried out over the summer months to reduce the moisture. Wet woods emit more smoke and creosote. On the other hand, seasoned logs are more efficient and cleaner. Seasoned wood looks darker and has cracks in the end grain, and is hollow when tapping. Keep your logs outside, neatly stacked and with the top covered, but allowing air circulation to them.
Be aware not to overload your fireplace or stove, as overloaded appliances generate more smoke and produce less heat. In addition, overloaded fires can produce dangerous levels of carbon monoxide. If you have an older appliance with a metal lining, inspect the liner regularly for signs of wear and tear that could cause a chimney fire.
The EPA recommends using split, dry and well-seasoned wood to help reduce the amount of smoke you breathe in your home. Make a fire using small pieces. Avoid using softer woods like pine, which are a great for starting your fire up and running but should not be used for anything other than. These softer woods have resin and sap that when burned, releases too much creosote in the chimney.
Maintenance
A warm fire in a wood burning fireplace is the perfect way to enjoy the cold nights of winter. However, it is important to maintain your fireplace in order to ensure that you receive the maximum benefits from your fire. Regularly cleaning and inspecting your fireplace is the best wood burning stove way to prevent problems that could develop. This prevents the accumulation of creosote buildup, and also keeps the chimney clear for maximum efficiency.
Creosote, a dark, crusty flammable material that forms in the flue when wood does not completely burn. When a lot of creosote accumulates, it can lead to chimney fires. These are the second most frequent cause of fires in homes across the United States. The failure of a fire to completely burn can be caused by a number of reasons such as dampers that are not properly sealed and cracks in the chimney's liner, and a lack or regular cleaning and ash removal.
Creosote can build up excessively when wood is not properly treated. This is because up to half of 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 water vapor produced then condenses into creosote and is released into the air as part of smoke.
Soot is another noxious product of burning wood. Soot is softer than creosote, but it can cling to the walls of your fireplace and block air flow. It is also a fire risk because it can ignite easily when exposed to combustible gases.
Remove the ashes from your fireplace and store them in an ash bucket made of metal. Keep it outside on a non-flammable area. The ashes can also be used as sources of nutrients for plants So don't forget to spread them out across the lawn!
It is recommended that a Certified Regency Dealer inspect your fireplace and chimney regularly. The technician can check for cracks, creosote levels, soot levels as well as a properly shut damper and the condition of the catalyst. If you have a double-stage chimney that includes an air tube, you must remove the catalyst and visually inspected for any blockages. Consult your user's manual for instructions on how to do this for your particular unit.
