How a Wood Burning Stove Works

Wood burning woodburning stoves - roll-express.ruwww.quilt-blog.de - can be a lovely addition to any home. However they should be used only with properly seasoned wood.

Older stoves that did not utilize secondary combustion allowed air to enter the chimney and burn above and below the fuel which resulted in pollution and loss of energy.

Modern wood stoves use superior combustion principles that divides air supply into two stages. This lets them improve the efficiency of heating while generating lower emissions.

Efficient Combustion

The combustion efficiency of your wood stove is a measurement of how efficiently your wood is transformed into heat. The efficiency of the heating transfer is the amount that heat is transferred from your stove to the room. A wood burning stove with high combustion and heating transfer efficiencies will make use of less fuel and generate less waste, like ash, carbon monoxide, and steam.

Modern wood stoves generally have high combustion efficiencies, as they have sophisticated design features that allow them to maximize their burn and use less wood. These stoves also emit less emissions, particularly stoves that are EPA-certified and require a catalytic combustor to clean exhaust gases as they leave the stove. These cleaner stoves are a great choice for homeowners who want to minimize their impact on the environment, while still enjoying the warmth and comfort of a wood burning stove.

The improvement of the efficiency of your wood stove is a matter of correct operation and maintenance. The most important factor is to ensure the combustion process is controlled, which is accomplished by maintaining a fire in the stove by regular additions of small pieces of wood regularly. This will prevent the buildup of flammable creosote inside the chimney, which could cause the electric stove heaters to become less efficient.

Another important factor in the efficiency of a wood stove is using properly dried and seasoned firewood with less than 20 percent. Dry and seasoned wood will not only offer more heat for the same fuel, but it will also create less air pollution and produce less smoke.

The Environmental Protection Agency has established guidelines that restrict the amount of smoke and other pollutants a new stove can emit within an hour. To comply with the EPA guidelines, the majority of modern wood burning stoves for sale stoves use secondary combustion or catalytic combustor in order to regulate combustion and limit the amount of pollutants they emit. If you're looking to purchase an wood-burning stove that is in compliance with EPA emission standards, search for one that has an EPA certification sticker. It must also have a smoke emission rate less than 4 grams per hour.

Catalytic Combustion

Catalytic woodstoves utilize a honeycomb combustor woodburning Stoves made of ceramic that is coated with noble metals such as palladium or platin. The combustor operates in similar to what your catalyst in your car works to clean your exhaust. The noble metals in the combustor react with particulates and chemicals in the smoke and break them into harmless end products like water and carbon dioxide.

This enables the stove to produce lower emissions and burn much more efficiently than other models without losing heat output or efficiency. The combustor performs its best when the gas temperature in the flue is 1,000degF or greater. If the fire is burnt in a low flame, the gases inside the stove aren't able to reach this temperature, and the combustor won't function properly.

The combustor can be damaged by burning foreign materials such as trash, paper logs, treated or painted wood. The burning of these materials can result in "masking" which covers the cells of the combustor with a substance that stops it from working according to its intended. Masking can also result from closing the bypass damper too soon or refueling with wet wood. If the combustor cells are not regularly cleaned of creosote and fly-ash it could cause smoke spillage.

The combustor, if properly operated and placed properly, will give years of reliable operation. It will require minimal maintenance other than cleaning off the soot from its surface after a prolonged burn and then dusting it with a dry, soft bristled brush.

The combustor comes with a bypass damper which is opened to start a fire and shut to load the stove. Check the bypass damper for the "operate catalyst" indicator which shows when your combustor is operating within its ideal temperature range. The operating range of your combustor may be decreased if you close the bypass damper too soon. Closing the bypass damper too early can reduce the temperature of the inlet to the combustor and could cause damage to it. If you're not sure how to operate the bypass damper, consult your stove's instruction manual or contact our customer service department for assistance.

Airflow Controls

Air flow controls are essential to ensure that your wood stove burns safely and efficiently. The primary, secondary and tertiary systems all work together to ensure that your fire burns efficiently. Each air system plays a distinct role in the combustion process.

The air control that is situated either below or within the door of your stove, controls the amount of air allowed into the firebox. More air will burn the fire faster but it could also increase the chance of creosote and chimney smoke. The ideal is that the air control should be opened for a short period when lighting your wood stove.

Once you have reached the desired heat level then you can slowly shut the primary air control until the desired temperature is achieved. The stove or chimney should not emit any smoke as this could indicate the combustion is not efficient.

Secondary airflow controls pump oxygen into the top of your stove, typically in the form of air jets placed above your fire. This is the most crucial aspect of managing your fire. Without it the fire will burn too fast and produce an excessive amount of smoke.

Tertiary airflow is a final stage of the airflow system of your stove and is carried into the updraft area or chimney. This creates a strong draft inside the flue, which allows your fire to function at its peak.

It is important to note that the wood stove you have was designed and optimized for burning wood for fire only. Any other type of combustible will not burn properly in your wood stove and could result in high levels of emissions and possibly chimney fires. The best type of combustible to use is wood that has been dried for at least six months, though softwood works just as well. Avoid using combustibles that are made of cardboard and paper, as these can cause toxic fumes and the build-up of creosote or ash within your stove log burner. It is also recommended to avoid placing any logs or other combustibles on the top of your stove because this could cause them to explode.

Safety

Wood burning stoves can be a great alternative to electricity, especially when your area is susceptible to frequent power outages. However, they can also be risky if they are used in a way that is not properly. They can produce harmful chemicals that can affect your health. They can also cause a fire hazard as well as carbon monoxide poisoning. You can reduce the risk by taking a few simple precautions.

Make sure you use only dry, clean firewood in your wood-burning stove. Never use gasoline, kerosene, charcoal starter fluid wrapping paper, or any other flammable substances to start or rekindle a flame. Never burn treated wood or painted wood, or wet wood. Keep the flue wide open to let plenty of oxygen in. Always add wood in small increments and don't let the fire get too hot. If you are in a smoke-control area, never use an indoor fire.

Make sure your stove and chimney are properly installed. A poorly-installed wood stove could result in a chimney fire that can release toxic gases into your home. It is also important to have the chimney swept and checked regularly. Make sure the chimney flue is not able to leak, which could result in carbon monoxide poisoning.

It's a good idea to store your wood in a shed or a tarp. This will help the wood to dry out and grow faster. To minimize the risk of fire, you should keep the wood away from other heat sources. It's recommended to set your stove on a non-flammable surface such as tiles.

You must be aware of your children's activities around the stove if you have young ones. They may try to play with the ash hot or even touch the fire which can be hazardous. It is recommended to keep all flammable objects at least three feet away from the stove. You should also think about installing a heat shield to protect walls and other surfaces from damage. It's also an excellent idea to have your family practice home fire drills. This can help you escape your home in the case of an emergency.
