5 Killer Quora Answers On Wood Burning Fires > 자유게시판

Wood Burning Fires Need to Be Hot and Clean

wood burning stoves uk burning fires are not only comforting and mesmerising they're also a vital aspect of our health and well-being. They need to be warm and clean in order to be effective.

Unseasoned, or green, wood has a high moisture content that makes it challenging to burn and light efficiently. The seasoned, or kiln dried wood has a lower moisture content and is more easy to ignite and keep burning.

Efficient Combustion

A wood fire must be sufficiently hot to draw out moisture and reach temperatures of 540 deg F ( 800 deg F in ideal conditions) at which the secondary combustion process starts. This is the most crucial step to efficient combustion of the fuel while minimizing pollution smoke, creosote, and buildup in the flue.

It is important to note that the temperature required for secondary combustion varies with the type of fuel used and the conditions in the environment. Use seasoned firewood that has a moisture content of less than 20% to reduce the variations.

The amount of air provided to a flame can also have a significant influence on its heat output and burning time. The more oxygen that is available, the hotter the fire will burn. A wood fire will produce less energy and burn at a slower rate when the air supply is limited.

A wood stove or fireplace insert fitted with an adjustable air damper will maximize the burn time and efficiency. The wide-open setting allows the fire to get all the oxygen it needs and quickly exhaust the fuel supply. A fire that is contained within a small space is less likely to spread.

A load of firewood that is well-dried is also essential for efficient wood burning. When wood is freshly cut and hasn't had time to dry out, it will have high water content that may make it difficult for logs to burn. For optimal performance it is recommended that you use only seasoned wood burning stoves on sale that has been stored outside wood burners for six to nine months.

Another thing to consider is the BTU content of different 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 much more, meaning they offer more heat for the same amount of wood burned. This is why it's crucial to think about your heating needs and fuel costs when selecting your firewood.

Clean Burning

Wood smoke can create indoor air pollutants, which can cause irritation to lungs and respiratory distress in seniors and children. These pollutants include volatile aromatic hydrocarbons (PAHs) like benzo-a pyrene and formaldehyde and volatile organic compounds like benzene. When firewood is burned the volatile tars like creosote also get released.

Smoke from poorly-designed wood stoves and fire places can cause poor air quality outside by decreasing visibility and causing photochemical smog. However, new clean burning fireplaces and wood stoves that incorporate modern combustion technology when used properly, can greatly reduce the emissions.

Stage 1 - Moisture vapourizes: As the log heats up it releases water vapor that escapes down the chimney flue. This takes more energy than when the log was dried prior to burning. This also wastes energy that could be used for heating your home.

In the flue, the vapors mix with carbon particles and form smoke. Smoke is among the major sources of particulate matter and smog that is found in the air.

Fireplaces and wood stoves equipped with clean burn technology, if utilized correctly, can dramatically reduce this issue by burning the logs to charcoal state which releases much less volatile gases, as well as producing the majority of the energy in the log from usable heat.

Avoid using damp, sour or decayed wood to light your fire. It's more difficult to burn and creates more creosote. Don't overload the stove with thin and soft woods like fir or pine. They require more energy to burn and produce more smoke, which can cause chimney fires.

Use a metal bucket to scoop ashes from the stove, and always wait until they cool before handling them. Be sure to store or dispose of them correctly as ashes can ignite if exposed to water, and they pose a risk in landfills. Use them in your garden or at home instead.

Storing, seasoning and properly burning your wood can help you save money and keep your stove running efficiently. It is also crucial to regularly clean your chimney to get rid of creosote and particles, as well as prevent chimney fires and ensure the safety of your operation.

Safety

It's hard to beat a warm fireplace in the winter cold However, safety precautions should be taken. If fires are not properly constructed or tended to, or left unattended, dangerous fumes can escape into the home, and potentially dangerous creosote deposits can build up inside the chimney. These deposits could block the flue, inhibit airflow and cause your furnace or wood stove to operate less efficiently.

Never burn treated, painted, or household trash in your wood-burning oven or fireplace. They produce noxious gases and may release toxic fumes such as carbon monoxide. Do not use flammable liquids as a fire starter. Gasoline, lighter fluid and kerosene can cause fires in chimneys which can increase emissions and create toxic creosote.

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

Only use wood that is seasoned in your stove or fireplace. Seasoned wood is dried through the summer to reduce moisture content. Wood that is wet produces more smoke and creosote, whereas seasoned logs burn much more cleanly and more efficiently. The wood that is seasoned is darker and cracks appear along the ends of the grain and sounds hollow when you tap it. Keep your logs outside stacked neatly with the top securing with a breathable air circulate around them.

Be aware not to over-load your fireplace or stove as appliances that are overloaded produce more smoke and less heat. Overloaded fires can also generate dangerous levels of carbon monoxide. If you own an older appliance with a lining made of metal, you should inspect the liner on a regular basis for signs of wear and tear that could cause a chimney fire.

The EPA recommends reducing smoke inside your home by using dry, split and well-seasoned wood and constructing a hot fire with small pieces. Avoid using soft woods like pine. Pine is a good starter material for the fire, but it shouldn't be used more than. These softer woods have sap and resin which is a result of burning, and deposits excessive creosote into the chimney.

Maintenance

A warm fire in a wood-burning fireplace is a great method to relax during the cold winter nights. It is crucial to keep your fireplace in good condition to make the most 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 for maximum efficiency.

If the wood doesn't fully burn, creosote forms in the chimney. If a substantial amount of creosote is accumulated, it can trigger chimney fires, which are the second-leading cause of house fires in the United States. A number of issues can cause a fire to fail to burn completely, including dampers that are improperly closed and cracks in the chimney liner and the absence of regular cleaning and ash removal.

Creosote may build up excessively when wood is not properly seasoned. This is due to the fact that up to half the weight of a piece wood is water. This water boils during the fire and releases heat. It also consumes energy. The water vapor produced is then absorbed into creosote or is released into the air as a part of smoke.

Soot is another noxious byproduct of burning wood. Soot is softer than creosote. However, it can stick to the walls of your fireplace and block air circulation. It could also pose a fire hazard because it can ignite easily when exposed to gasses that are combustible.

Take the ashes out of your fireplace and put them in an ash container made of metal. Keep it outside on an unflammable surface. The Ash can also be used as an energy source for plants Don't forget to spread them around the yard!

Regularly ensure that your chimney and fireplace are checked by a Regency Dealer Certified. The technician will be able to check for cracks in the chimney, creosote and soot levels, a properly sealed damper and also the condition of your catalyst. If you have a two-stage chimney that has an air tube, the catalyst should be removed and checked visually for blockages. Consult your user's manual for directions on how to accomplish this for your specific unit.
