This Is The Ultimate Guide To Wood Burning Fires

Wood Burning Fires Need to Be Hot and Clean

The warmth and ambiance of a wood-burning fireplace is not only soothing and mesmerizing, but also essential to our health and well-being. However, they must be clean and hot in order to function effectively.

Green, or unseasoned, wood has high moisture content that makes it challenging to burn and light efficiently. Kiln dried or seasoned wood has a lower moisture content, making it much easier to ignite and keep a flame.

Efficient Combustion

The wood fire should be sufficiently hot to burn off moisture and reach temperatures of over 540 degrees F. The heat-producing process of secondary combustion starts at 900 degrees F (in ideal conditions). This is the most important step to efficient combustion of 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 of the environment. Make sure to use firewood that is seasoned and has a less than 20% to limit the variations.

Additionally, the amount of air that is pumped into a fire can significantly impact its heat output and time to burn. The greater the oxygen supply, the hotter a fire can burn and the shorter its burn time. When the air supply is limited, however, a wood fire will produce less heat and burn slower.

To increase the time of burning and efficiency, a wood stove or fireplace insert must be equipped with an adjustable air damper. Wide open settings allow the fire to consume all the oxygen available and quickly exhaust the supply of usable fuel. The converse is true of an area that is limited to a smaller area where the fire is unable to expand as far.


A firewood pile that has been properly dried is vital for efficient wood burning. When wood is freshly cut and hasn't had the chance to dry, it will have high water content that may make it difficult to burn. For very small wood burner , it is recommended that you only use seasoned wood that has been stored outdoors for six to nine month.

Another thing to consider is the BTU content of various types of wood. For instance, white pine or spruce trees may be cheaper than eastern hardwoods such as black locust and shagbark hickory, however the BTU values of the latter are much higher, meaning they will provide more heat for the same amount of wood. This is why it's crucial to consider your heating requirements and fuel costs when selecting your firewood.

Clean Burning

Wood smoke can create indoor air pollution that can cause irritation to the lungs and respiratory distress in seniors and children. These pollutants include volatile organic compounds (VOCs) such as 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 is burnt.

Smoke from poorly-designed wood stoves and fire places could cause poor air quality outside by making it harder to see and causing photochemical smog. When used correctly however, modern combustion technology in new clean-burning wood stoves and places can reduce these emissions.

Stage 1 - Moisture Vaporizes As the log gets heated, it releases water vapor which escapes up the chimney flue. This requires more energy than when the log was dried prior to burning. This also wastes energy that could be put to use to heat your home.

The vapors in the flue with carbon particles to create smoke. Smoke is a major contributor to particulate matter in the air and is among the major sources of smog that we encounter on clear days.

Wood stoves and fireplaces with clean burn technology, when properly used, can greatly reduce this problem by converting the logs into charcoal state which releases much less volatile gases, as well as creating the majority of the energy contained in the log from usable heat.

Avoid using damp, sour or rotten wood to light your fire. It is more difficult to burn and generates more creosote. Avoid overburdening the stove with thin and soft woods like fir or pine. They require more energy to burn and create more smoke, which could cause chimney fires.

Use a bucket made of metal to scoop up 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 in the presence of water and they can be hazardous in landfills. Instead, you should use them around your garden or in the house.

Storing, seasoning and correctly burning your wood will help you save money and ensure that your stove is operating efficiently. Cleaning your chimney regularly is essential to eliminate creosote and particulates as well as other debris that is deposited. This can also stop chimney fires as well as keep your chimney operating safely.

Safety

There's nothing like a cozy fire to warm up chilly winter evenings, but proper safety precautions are necessary. If fires are not constructed correctly 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 chimney and restrict airflow, causing your furnace or wood stove to not work as effectively.

Do not burn treated, painted, or household waste in your wood-burning stove or fireplace. They emit noxious gasses and release toxic fumes, like carbon monoxide. Also, do not use the flammable liquids to ignite fires. Kerosene, gasoline and lighter fluids can cause an increase in emissions, create toxic creosote, and even cause chimney fires.

Keep combustibles, such as furniture or curtains, as well as toys, at a safe distance away from your fireplace or stove. Never hang clothing near or on the fireplace that is burning wood. 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. The wood that has been seasoned has been dried over the summer months to reduce the moisture. Wood that is wet produces more smoke and creosote, however, seasoned logs burn more cleanly and more efficiently. Seasoned wood is darker and cracks appear along the grain's end and makes a hollow sound when you tap it. Keep your wood outside, neatly stacked with the top covered, but allowing air circulation around them.

Appliances that are overloaded produce more smoke and less warmth. In addition, overloaded fires can produce dangerous levels of carbon monoxide. If you have an older appliance that has an aluminum liner, be sure to check it regularly for signs of wear. This can lead to an explosion in the chimney.

The EPA recommends using split, dry, and well-seasoned wood to reduce the amount of smoke that your home produces. Make a fire using small pieces. Avoid using soft woods like pine. Pine is a good starter material for the fire, but it shouldn't be used beyond that. These soft woods are brimming with sap and resin, which when burned, create large amounts of creosote into the chimney.

Maintenance

A warm fire in a wood-burning fireplace is the perfect way to warm up during the cold nights of winter. But, it is essential to maintain your fireplace in order to ensure that you receive the maximum enjoyment from your fireplace. Regularly cleaning and inspecting your fireplace is the best way to avoid problems that may occur. This prevents creosote buildup and keeps the chimney clear for maximum efficiency.

If the wood doesn't fully burn, creosote forms in the chimney. If a significant amount of creosote accumulates, it can cause chimney fires, which are the second leading cause of house fires in the United States. A number of issues can contribute to a fire's failure to fully burn, such as dampers that are improperly closed, cracks in the chimney liner, and the absence of regular cleaning and removal of ash.

Creosote can accumulate excessively when wood isn't properly treated. This is because up to half of the weight of a piece wood is water. The water is heated during the fire and releases heat. It also consumes energy. The water vapor that is created then condenses into creosote, or is released into the air as part of smoke.

Another harmful byproduct of burning wood is soot. Soot, while softer than creosote, is able to block airflow and stick to walls. It is also a fire risk because it ignites easily when exposed to gasses that are combustible.

Remove the ashes from your fireplace and store them in an ash bucket made from metal. Keep it outside on a non-flammable area. The ashes can also serve as a source of nutrients for plants Don't forget to scatter them across the backyard!

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