Wood Burning Fires Need to Be Hot and Clean

Wood burning fires are not just a relaxing and enchanting experience, but they're a critical aspect of our health and wellbeing. They must be hot and clean to be effective.

Unseasoned, or green, wood is very moist that makes it challenging to ignite and burn effectively. Kiln dried or seasoned wood has a lower moisture content, making it easier to ignite and maintain a fire.

Efficient Combustion

A wood fire has to be sufficiently hot to draw out moisture and reach temperatures above 540 deg F ( The process of producing heat from secondary combustion starts at 900 degrees F (in ideal conditions). This is the first step in efficiently burning fuel while reducing pollutants and smoke in the flue.

It is crucial to understand that the temperature needed for secondary combustion depends on the kind of fuel used and the conditions around it. The best way to limit the variation is to use dry firewood that is seasoned and has a moisture content below 20%.

The quantity of air 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 produce less energy and burn slower when the air supply is slowed.

To maximize burn time and efficiency, a wood stove or fireplace insert should be equipped with an adjustable air damper. The wide-open setting allows the fire to take all the oxygen it can get and quickly drain the fuel supply. The reverse is true for an area that is limited to a smaller area in which the fire cannot expand as far.

A well-dried firewood load is also critical for efficient wood burning. Wood that is freshly cut and hasn't been dried will contain high levels of water which makes it difficult to burn. For optimal performance it is recommended that you only use seasoned wood that has been stored outside for six to nine months.

The BTU content of wood is another factor to take into consideration. For example 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 higher, which means they provide more heat for the same amount of wood. It is crucial to consider your heating requirements and fuel costs when choosing your firewood.

Clean Burning

Wood smoke can trigger indoor air pollutants, which can cause irritation to the lungs and respiratory distress in seniors and children. These pollutants include volatile aromatic hydrocarbons (PAHs) such as benzo-a-pyrene and formaldehyde and volatile organic compounds like benzene. Volatile Tars (such as creosote) are also released when firewood is burnt.

Smoke from poorly-designed wood fireplaces and stoves can cause poor air quality outside, making it harder to see and causing photochemical pollution. However, new, clean burning fireplaces and wood stoves with modern combustion technology, when used correctly can significantly reduce the emission.

Stage 1 - Moisture Vaporizes: As the log gets heated, it releases water vapor, which escapes through the chimney flue. This consumes more energy than if the log was seasoned to dry prior to burning. This is a waste of energy that could be used to heat your home.

The vapors in the flue with carbon particles to produce smoke. Smoke is among the main sources of particulate matter and smog that is found in the air.

Fireplaces and wood stoves that use clean burn technology, if properly used, can greatly reduce the risk of this by burning the logs to charcoal state, which releases far less volatile gasses, and creating the majority of the energy contained in the log from usable heat.

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

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

Storing, seasoning and correctly burning your wood will help you save money and keep your stove running efficiently. It is also important to clean your chimney regularly to remove deposited creosote and particles and also to prevent chimney fires and ensure safe operation.

Safety

There's nothing like a cozy fire to keep warm during cold winter nights, but the right safety precautions are necessary. When fires aren't properly built, burned or left unattended, dangerous fumes can be released into the home and dangerous creosote deposits can build up within the chimney. These deposits can clog the flue, impede the flow of air and cause your wood stove or furnace to work less efficiently.

Never burn treated or painted freestanding wood burning stove, household waste paper, rags, or other combustible materials in your wood-burning stove or fireplace. They can release toxic fumes like carbon dioxide and produce toxic gases. Avoid using flammable liquids as a fire starter. Gasoline, lighter fluid, and kerosene could cause fires in chimneys, increase emissions, and create toxic creosote.

Keep combustibles, like furniture or curtains, as well as toys, at a safe distance from your fireplace or stove. Never hang clothing near or on your wood-burning fireplace. Make sure your children are aware that the fire is hot and should not be touched.

Use only seasoned wood for your stove or fireplace. The wood that is seasoned has been dried during the summer months to reduce the moisture content. Wet woods emit more smoke and creosote whereas the wood that has been seasoned is more efficient and cleaner. Seasoned wood is darker, has cracks along the ends of the grain and sounds hollow when you tap it. Store your logs outside, neatly stacked and with the top covered, but permitting air circulation around them.

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

The EPA suggests using dry, split and well-seasoned wood in order to help reduce smoke in your home. Build a hot fire using small pieces. Avoid using softer woods such as pine, which are good starter material to get your fire up and running but should not be used for anything more than. These softer woods contain sap and resin that burns, if burned, will create excessive creosote in the chimney.

Maintenance

A warm fire in a contemporary wood burners burning fireplace is an ideal way to warm up during the cold winter nights. It is essential to keep your fireplace in good condition to get the most enjoyment of it. Regular cleaning and inspection of your fireplace is the best way to avoid problems that may develop. This prevents the build-up of creosote and keeps the chimney clear for maximum efficiency.

Creosote is a dark, hard, flammable substance that develops in the flue when wood does not burn completely. If a large amount of creosote accumulates, it can trigger chimney fires which are the second-leading cause of house fires in the United States. The inability of a fire to completely burn can be caused by a number of causes such as dampers that are not properly sealed and cracks in the chimney's liner and the absence of regular cleaning and ash removal.

Incorrectly seasoned wood contributes to the accumulation of creosote to an excessive degree. 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 created then condenses into creosote, or is released into the air as part of smoke.

Soot is another harmful byproduct from burning wood. Soot, while softer than creosote can block airflow and adhere to walls. It could also pose an ignition risk since it ignites easily when exposed to combustible gases.

Remove the ashes from your fireplace and put them in an ash container made of metal. Keep it outside on a non-flammable area. The ashes can also serve as an energy source for plants So don't forget to scatter them across the yard!

It is recommended that a Certified Regency Dealer inspect your chimney and fireplace on a regular basis. The technician will be able to look for cracks in the chimney, creosote and soot levels, a properly closed damper and 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 do this for the particular unit you have.
