The Dangers of a Wood Burning Fire

A wood-burning fireplace can be a comfortable and relaxing experience. However, it could also produce harmful combustion products. It is important to learn about the way that wood burns and how to properly use your fireplace.

Choose seasoned logs or Kiln dried logs. Seasoned logs hold less moisture, and they are able to burn longer and hotter than unseasoned logs.

Burning Time

Heating wood with wood is a well-known and efficient method of heating. However, this kind of fire can release outdoor and indoor emissions that can be harmful to human health. A well-designed fireplace, utilized with care can lessen the negative effects of burning wood.

The duration of a fire is dependent on the temperature. The temperature of the fire affects the quantity of smoke produced, as does the amount of carbon monoxide released. If carbon monoxide levels are high, they could impede the escape of occupants from a burning building. To avoid this, it is essential to keep the fire at a low level of heat.

In the beginning of a fire, volatile gases such as alcohol and methane are released from the wood's cellulose. These gases are combustible but non-combustible based on the moisture levels and the pyrolysis temperature of the sample. The temperature of pyrolysis increases to around 325 degrees Celsius. At this point, cellulose begins to decompose and forms charcoal and tar. This process is referred to as wood pyrolysis.

Wood burning releases other harmful combustion products, such as dioxins, polyaromatic hydrocarbons, and PAHs. PAHs have been linked to cancer and other diseases, both in humans and in animals. They also can contaminate water and soil. To lessen the negative harmful effects of PAHs wood must be burned in a well ventilated area.

A wood stove with an extended burn capacity can keep visible flames while using a minimal amount of fuel. This method of burning involves laying the portable wood fireplace wood heater - mybookmark.Stream - with light firewood and heavier logs to stop the fire from burning too fast. This technique can be used to build an open fire to generate high temperatures, either over night or while you're at work.

The time it takes to burn a fire is determined by many factors, including the moisture content in the wood. Dry wood will have a slower burning time than damp wood. The absorptivity of the surface can also affect its burning time. Simms [59] found that the critical heat flux needed to ignite oak and mahogany samples was significantly lower with coated surfaces than those without.

Temperature

The temperature of the fire is critically crucial. It affects the speed at which it burns, as well as the heat it generates. It can also affect the danger in the event of a person being burned. It also affects how much smoke is generated. If there is a lot of smoke, it could irritate the eyes and throat which is why people should avoid breathing it in.

When wood is burned it generates lots of heat and can even reach high temperatures. The temperature of a flame can vary based on the type of wood that is used and the moisture content. Wet wood, like, will burn at lower temperatures than dry wood. This is due to the fact that wet wood will absorb more water and less heat. It is crucial to use dry wood and you must ensure that the wood has been seasoned before burning it.

When the wood reaches its maximum temperature of combustion it will release a lot of heat and ash. The amount of ash that is released will depend on the type of wood burning and the degree to which it burns. Certain types of woods, like oak and larch create very little ash. Others, such as birch, can create an enormous amount of ash.

When the wood starts to burn it will go through a three-stage process known as pyrolysis. The process begins with a chemical reaction that transforms the organic compounds found in the wood into methane and carbon dioxide. The resultant gases are taken up by the air around them. When the wood is heated these gases will rise and ignite the wood's surface which will create a flame that will heat it up until it combusts.

The temperature of a wood burning fire can be extremely high and it can damage surfaces when it comes into contact with them. Avoid touching the fire with your naked hands as it could cause serious burns. You can lower the risk of burning yourself by wearing gloves and working in a ventilated area. Masks are recommended when working around fires that burn wood to avoid breathing in smoke.

Smoke

Wood burning fires generate smoke, a mixture of fine particles and gases (also known as particulate matter, or PM) that contain harmful air pollutants. PM from wood combustion can contain harmful organic compounds such as benzene and formaldehyde, as well as mineral particles such as calcium, potassium and magnesium. The presence of these particles can lead to a range of health effects including respiratory and cardiovascular diseases, as well as cancer. When people inhale smoke from wood they also breathe in carbon monoxide (CO) which is an inert gas with no odor and color that can cause deadly poisoning in small doses.

The smoke that is produced by wood fires is mostly due to volatile organic compounds (hydrocarbons) that evaporate from the burning material. The smoke also contains some water vapor, the byproducts of incomplete combustion (such as creosote), and a small amount of unburned Ash.

When deciding on the type of wood to use in your fireplace or woodstove It is best small wood burning stoves to choose seasoned firewood. Split logs that have been kept out of the elements and allowed to dry for a certain amount of time until they reach an average moisture content of 20 and 25 percent, burn less and produce less creosote. A good way to check the moisture content of a log is to knock it on both sides. Damp wood will have a sluggish sound, while mature logs will produce an edgy sound.

The heat produced by wood fire draws air from around it, the smoke and other byproducts of combustion are pushed out by the chimney. If the home's ventilation system is not adequate it could mean that the chimney is not able to draw enough air, and may cause a back draft, which could cause the byproducts from the fire to build up inside the home. This could result in an accumulation of dangerous carbon monoxide, as well as flammable creosote and cinders.

Smoke from wood-burning fires could be particularly hazardous to older people, those with heart or lung diseases, children, and outdoor fans. Smoke from wildfires can affect the health of older adults, people suffering from heart or lung disease, children and those who exercise outdoors.

Safety

If you're using a wood burning fire, there are certain precautions to take to minimize the risk of accidents and fire damage. You should always make use of an electric fireplace or wood stove screen and keep anything that is flammable at 3 feet from the fire. Carbon monoxide and Smoke detectors should also be installed in your home to warn you when hazardous gases are detected. It is not advisable to leave a fire unattended because even a small flame could cause an explosive explosion. Also, you should employ a metal shovel and the ash bucket to clear the ashes from your fireplace, or wood stove and keep it away from anything flammable.

Lighting the Fire

To start an fire, first lay down a layer of cleft dry logs on the top of a bed of ash. Add a layer of twigs, kindling and ash to the pile. Make sure there is enough space between each piece of wood to allow air flow, as this will prevent the fire from dying out too quickly. Add a few flames for extra assistance in getting your fire up and running.

Open windows to let the fire get the oxygen needed to make it burn brightly. This is particularly important for modern homes that are usually sealed tightly and have no natural ventilation or drafts.

When your fire has started to heat up, you can start adding progressively larger pieces of wood to it. However, it is important to remember that even the most seasoned hardwoods such as oak and hickory produce lots of creosote when burned and you should avoid burning them as long as possible.

If you can, only use wood that has been seasoned or kiln dried, as this will reduce the chance of creosote forming up in your chimney. However, if you do have to use fresh or green cut firewood, be sure that you do it with great care because it will produce more smoke and may produce more creosote.
