WHAT KIND OF FIREWOOD IS BETTER FOR A CAST IRON STOVE? ? WHAT TO HEAT YOUR FIREPLACE WITH ?
A fireplace or stove is not just a decorative feature widely used in modern interiors; it is primarily a reliable source of heat released from the combustion of wood. The choice of fuel for the furnace fireplace or wood stove, affects not only the efficiency of the heater, but also on its appearance, durability and heat output. Therefore, the question of choosing fuel for the stove or fireplace should be approached responsibly. We will try to tell you in detail what types of fuel can be used to heat the furnace or fireplace, and what is better to refuse to use.
WHAT CAN HEAT A FIREPLACE, STOVE ?
Of course, the real classic fireplace, is not associated with anything other than wood. But, modern conditions of life make adjustments and in addition to aesthetic beauty of live flames, the consumer also requires that the combustion of fuel, released the maximum amount of heat, and the period of the furnace from one wood charge, was as long as possible. All this led to the fact that for fireplaces and stoves, manufacturers began to produce long-burning wood. pressed fuel, the structure resembling pellets, but having a larger size. Hence the question: “Can a wood stove be stoked with briquettes? ?”. Pressed logs, Euro firewood, briquettes. all this is the name of one type of fuel produced from crushed wood of different species, coal, toa, and is characterized by a good heat output and a long burning period. However, heating the stove or fireplace with Eurofuel has a few peculiarities. Let’s look at them in detail: other briquettes, good fire and maintain a steady burning for 8 hours when fully loaded in the hearth. You will need to kindle briquettes in batches, first you need to light a small amount of firewood to let the pressed logs burn well, and then add a new batch of briquettes. The combustion time of euroloads of toa reaches 6 hours. When burning any kind of briquettes, whether they are fuel briquettes or wood briquettes the heat emitted is actually 30-50% higher than when burning ordinary firewood, while the burning time of Eurorod is almost twice as long. What makes it possible to achieve such a long burning time ? Comparing briquettes for burning and firewood, you need to understand the principle of the production process of pressed fuel. During processing, moisture is completely removed from the shredded raw material (specific humidity not exceeding 11%). Then, the small particles are pressed so that no voids are left between them, which provides a high density of briquettes and ensures uniform combustion without sparks, with minimal smoke emission, which is important for open fireplaces. In the production process, removed and resinous impurities, so, stoves and fireplaces are allowed to stoke briquettes even from softwood. However, please note that the heat output of pressed softwood fuel is less than that of hardwood counterparts. However, choosing what to heat the fireplace, the real wood or briquettes, keep in mind that the characteristic smell of burning wood and peaceful crackling is only possible by burning split firewood.
WHAT KIND OF WOOD TO USE FOR A FIREPLACE ?
The best firewood, which has a high efficiency and the greatest heat capacity, are harvested from hardwood. Beech and oak are optimal for stoking a fireplace or stove, you can use acacia, aspen or any fruitwood. Beech and oak are rightly considered “elite firewood. These types of wood burn smoothly and brightly, pleasing to the eye. During combustion, there is a pleasant and even crackling sound. Beech firewood, in terms of its heat output, is virtually unmatched. Similar characteristics distinguish oak firewood. Oak firewood burns for a long time and produces practically no smoke or sparks. The only disadvantage of these types of wood for kindling a fireplace or stove. their high cost.
The advantage of fruit wood is the unique aroma that enters the room during burning. It is accepted to heat living rooms with firewood from fruit trees such as alfalfa, pear and plum. Over time, with the constant use of “fruit firewood” in the room there is a persistent aroma of wood.
Alder and aspen firewood have a truly unique feature. When they burn, no smoke or soot is produced. over, fire formed by burning alder burns soot inside the chimney, which helps to clean the inside of the chimney and the subsequent settling of soot. If you use your fireplace or stove regularly, it is recommended that you warm them up with alder or aspen at least once every few weeks to prevent fouling the chimney. Do not forget that most fires are caused by an excessive buildup of soot inside the chimney !
Despite a variety of wood the most popular and demanded kind of fuel is a deciduous species. The most practical way to heat your stove or fireplace is with hazelnut, acacia, cherry, birch, maple. Thanks to the simple and inexpensive procurement of raw materials, the relatively low cost of the wood itself, these species of wood are the most suitable for furnaces, wood burning fireplaces and boilers. All these types of wood are good for chopping. Acacia is distinguished by the strongest heat emitted by coals. Birch wood, burns well even raw, but, in this case, it is required to monitor the constant inflow of fresh air and draft characteristics, since the lack of oxygen when burning birch wood leads to the formation of birch tar in large quantities, which contributes to rapid contamination of the furnace chamber and the glass surface.
The less suitable wood for burning. These are poplar and linden. Firewood has a low density and burns quickly, with minimal heat generation.
Regardless of the type of wood, all wood has the necessary requirements: it must be dry and not rotten.
WHAT NOT TO HEAT UP A FIREPLACE ?
On the length of use of the fireplace, its durability and appearance of the fireplace firebox with glass, has a significant impact. selected type of firewood. Besides the recommended types of wood described above, there are types of fuel that are categorically not recommended to burn in a fireplace or wood stove. is coniferous wood. Softwood is not dense, inside of it there are cavities filled with resinous sediments. When the next resinous substance ignites, a so-called “microburst” occurs. That is why sparks and embers pop out of the fireplace when the wood of spruce or pine burns. In addition, the moths burn with the release of large amounts of soot, which settles on the walls of the furnace chamber and contaminates the sight glass. Do not use spruce wood for the fireplace for another reason. When burning spruce or pine, in addition to the tar in the flue gases emitted, there is a large amount of soot, which has an oily structure. Soot settles on the inner surface of the chimney, which leads to a gradual increase in the dense layer on the inner cavity of the chimney. Under the influence of temperature, the tar layer thickens and hardens, making its removal almost impossible. Thus, the original cross-section of the chimney is narrowed, which subsequently has a negative impact on the draft. However, the main danger is that very often there is spontaneous combustion of soot inside the chimney that can lead not only to the pipe into disrepair, but cause a fire. It is not recommended to heat the fireplace and stove with damp wood. Wet wood. The source of soot, smoke and soot on the chimney walls. All this reduces the service life of the hearth and the smoke evacuation system as a whole.
Question: How to choose firewood for a fireplace
Smoking glass in the chimney fireplace stove? Fireplaces that do not burn well? In most cases, the fault is not the fireplace, but the wood. Even if the logs “look dry,” they can be source of problems. Which ones and how to avoid them. I explain in this article. About the author: Margarita Kleptsova. expert on wood stoves and fireplaces. Her portfolio (since 2004) includes 258 “from conception to live fire” fireplaces in private homes, and another 7 in public projects.
What’s the problemThe fireplace fireplace firebox is a complex engineering design. The quality of the work of the factory furnace is laid down by the manufacturer, but it also depends on other factors (installation and operation).
Manufacturer provides that: the wood flares up quickly, the flame in the furnace is high and beautiful, the wood burns slowly, giving a room comfortable heat, at the end of the burning (even the next day) in a room smells good just burning wood.
When something goes wrong in the operation of the fireplace, the manufacturer of the firebox is often blamed. However, as a rule, the cause of the problems lies not in the design, but in the operation of the fireplace. And more often than not, it’s in undried firewood. In constant use, poor-quality wood can even cause damage to the fireplace firebox.
- Wood that does not burn. damp or too resinous.
- Fire ignites poorly, the flame goes out quickly. the wood is unripe or too wet.
- Too low a flame. freshly cut or damp wood.
- Fire goes out and no bed of embers is formed. unsuitable wood or wood that is too tarry.
- Condensate forms on the inside of the firebox. unsuitable wood or wood that has been cut freshly or is too wet; slow burning of damp wood with the door closed.
- Fireplace doesn’t heat up. freshly cut or too damp wood, low quality wood.
- Firewood burns quickly (in less than an hour). raw firewood. Wood with high moisture not only doesn’t warm (despite the strong yellow flame), it also burns quickly. If you burn wet firewood, you lose at least 20% of power and increase fuel consumption (consumption).
- The glass gets dirty quickly. damp or unsuitable wood is used. If a damp softwood log is put in the firebox, the boiling tar it will throw up when burning can stick to the glass of the door. Such contamination is very difficult to clean.
- The room smells of wet soot (as after a fire). damp firewood is used. The smell is a signal that the chimney is clogged with creosote deposits and soot. Both are easily flammable. It is necessary to clean the chimney and stop using wet firewood, because there is a risk of fire in the chimney.
What can be wrong with firewood To ensure that all the physical processes of combustion and combustion proceed correctly, the fireplace is happy with warmth and beautiful flames, and the air around the house remains clean, the moisture content of wood should be 15. 20%. Such fire wood is considered dry and suitable for absolutely all fireplaces and furnaces.
When drying in domestic conditions the wood reaches the desired (optimal) humidity indicator in different time. Minimum drying period of firewood depends on the month when it is put in the pile. The warmer it is outside, the faster they will dry.
Unfortunately in Russia firewood is usually bought closer to the heating season. in August or October, or even on the New Year’s Eve (if the owners don’t live in their country houses all year round, but only plan to celebrate the holidays).
Look at the table: the drying time for firewood, bought in August. from 300 days, in October. 270 days. In other words, by the beginning of the heating season their humidity is excessively high. 50. 60%. Such firewood will be difficult to light, because it needs more energy to evaporate the water it contains. In turn, the evaporation of water from the wood will reduce the temperature in the firebox and condensation of water in the furnace and chimney. The result is contamination of the firebox, glass, and chimney; danger of a stove fire; and deterioration of air quality around the house.
Important: Smoke from burning wood contains mostly carbon dioxide and water, as well as varying amounts of microparticles, carbon monoxide, hydrocarbons, and other harmful compounds. Emissions arise when you burn too much wood, too much plastic, too much garbage, or too little or too little airflow into the furnace Question: How to get air to your fireplace
Fact: particles in the form of suspended particles can stay in the air around the house for days, and all those days we will breathe them in. These harmful compounds cause exacerbation of lung and heart disease, and the air with them is “unpalatable”.
When the combustion temperature is high enough (500 to 700 °C) and there is enough combustion airflow, there are fewer harmful emissions. Most of the smoke produced by proper combustion consists of harmless water vapor. Such smoke is practically invisible from the chimney and the chimney stays clean, without black sooty fouling.
When to buy firewoodThe best way to get perfectly dried (and inexpensive) firewood for winter is to buy it in March or April. If you put the firewood in an April bunker it will be 120 days dry (!) and will be ready for use at the beginning of the heating season.
But the July wood will dry out in 310 days and will not be ready for use until the next winter.
Another option is to buy firewood that has been dried in a special chamber to the humidity of 10%. But the price for such fuel is many times higher than for freshly cut firewood, so the option is suitable only for those who kindle a fireplace very seldom.
The best way to dry firewoodThe best option for drying firewood is outdoors under the sun with natural ventilation, and the lower logs should not lie on the ground. Inside the house, it is wise to have a reserve of firewood for several fires: such logs will additionally dry out, and the process of lighting the fireplace will be as easy as possible.
How to Cut Wood Stove Glass
Firewood for an open fireplace
The operation of open fireplaces imposes special requirements for fuel. So, the wood in this case should have a low combustion rate, and should not spark, as well as emit unpleasant odor. Conifers are immediately ruled out because they do not meet these requirements.
If we talk about suitable options, their list would look as follows:
- Oak. Ideal for an open fireplace. Oak firewood takes a long time to burn and gives off a lot of heat. Oak wood contains essential oils in its composition, which are emitted during burning and fill the room with a pleasant fragrance. If you use firewood without bark, it hardly sparks. The main disadvantage of this variant is the high cost.
Best Fireplace Inserts Consumer Reports
- Alder. A traditional Russian fuel that has been used for open fireplaces since very ancient times. Alder firewood produces a minimum of smoke and has a solid heat capacity. In addition, such firewood itself is quite attractive. they can be simply put in a pile, and they will already improve the interior.
- Birch. Birch firewood for a fireplace when burning almost does not emit carbon monoxide, and the smoke, in addition to smelling good, has disinfecting properties. A distinctive feature of birch firewood is that it can be used even with a considerable amount of moisture. The main disadvantage is the release of a large amount of soot, so when using such firewood will have to clean the chimney much more often than usual.
- Aspen. Aspen logs deserve attention for one very important quality. their use clears the chimney of soot. This quality allows you to significantly simplify the maintenance of the chimney structure. just once every couple of months to heat the fireplace, using aspen wood. The main disadvantage of such firewood. too low heat capacity, which does not allow to heat them constantly.
- Cherry, apple, and juniper. This kind of wood is ideal for an open fireplace, thanks to its whiff and minimal smell and sparks. In addition, such firewood can be used not only on its own, but also as a nice addition to the main fuel. Can be made a firebox for the fireplace with their own hands, which will not only allow you to stack firewood, but also will decorate the room with an original design.
Firewood for an open structure
Choosing what to stoke the fireplace of an open design, you need to consider that the smell of burning material enters the room. Therefore, wood species with high resin content are not suitable. But you can add some pine needles for a pleasant fragrance.
Alder firewood is considered to be of good quality. They are easy to identify by their orange color. In imperial times, alder was used for heating the sauna quickly. High heat output, pleasant smell and almost no smoke characterizes alder firewood.
common and less expensive birch wood. If you peel off the bark, the emission of smoke during combustion will be negligible. And birch bark is a great way to heat a fireplace. If the house is constantly stoked with birch, it is advisable to clean the chimney every month. This measure ensures a good draught during firing.
A pleasant aroma appears in the room when using wood from fruit trees. To fill the room with a healing smell, the branches of garden trees left after pruning are used. Raw material should be thoroughly dried.
Aspen firewood provides beautiful burning with low heat emission. It is recommended to stoke the fireplace several times during the season with aspen wood to clean the chimney from excess soot.
A type of wood for the fireplace
What kind of wood is better to heat the fireplace? Birch, needles? It is difficult to say for sure. Note that many people choose wood not by what species it is. Trees taken from your garden or other places are often “fed” to the stoves. In fact, all these raw materials can be used as a fuel!
Do not use furniture debris, fences, etc. for your fireplace.п. First, such materials burn rather poorly, in addition, they emit harmful substances, since they are impregnated with coatings.
How to store firewood
After buying firewood, they should be placed in a place where they can maintain their properties for a long time. The place is prepared well in advance. You can simply put the wood under the roof as you wish. But if you approach the process creatively, then from an ordinary pile can create a real masterpiece and decorate the garden plot. To keep the stack of logs from falling apart, they are often stacked, leaning three sides into the walls of buildings. It is necessary to know that firewood will bring a good heat output, only if properly stored.
It is necessary to find a proper place to store logs, and certain rules should be followed when storing firewood:
- The firewood pile should be placed not far from the house entrance, so it is convenient to go there in winter to get the next portion of firewood in any weather.
- Do not cut and chop firewood in winter, but before frost sets in.
- For firewood to burn well, it must be well dried. This condition is then maintained by special stacking of the stack.
- Do not store firewood in the lowlands, where there is a high level of humidity. Firewood will get damp again and may even rot. You won’t get good smell and good heat from such firewood.
- A canopy should be placed on top of the stack or the stack should be placed so that no precipitation gets into the stack through the top row. over, they must be well ventilated, for this purpose keep a certain distance.
To make the pile stable, it is possible to do the stacking “in a bind”.
But But remember The wood cut in winter time is put in a pile in 4-6 months. Spring and summer logs are dried longer, 8-12 months. It depends on the weather, the level of humidity, the place where the wood is dried.
Burning the stove with raw wood
To make a fire it is necessary to put a paper on the bottom of the stove. Prepare chipboard in advance. It is placed on top of the paper.
It is possible to kindle the stove with raw wood and to heat it with raw wood. Place firewood on top of the paper and chip mass in the form of a hut. Another option in the form of a well. Paper is lit. The flame burns into fine chips and begins to lick the damp wood. If you have not succeeded in lighting it the first time, you can try again. It will be more successful, because the wood has time to dry during the first burning.
There are many types of fuel for kindling the stove. The main thing is to make the right choice, which is the most acceptable to these conditions. Compare the costs and the amount of heat you plan to get.
Safety rules for firing up the fireplace
Where there is a fire, you must be as careful as possible. When firing up the fireplace, there are several rules to follow:
- Keep a close eye on the fireplace and the chimney. They should be without cracks and not dirty. If you use your fireplace often enough, a lot of soot and soot will build up on the walls of the duct over time. Because of this the draft of the chimney will be less, and sooner or later the smoke will begin to penetrate into the room. And as we know, carbon dioxide is dangerous for humans and animals. Getting burnt or poisoned is a dubious prospect.
- The ignition of the fireplace should be gradual. First you heat small logs, and only after they are burned enough, you can increase the amount of fuel. If you think you can put fuel in the fireplace and the flames will burn brighter, you are wrong. All the heat just goes down the chimney, not the heating.
- It is not necessary to fill the firebox to the top with fuel, as the walls of the fireplace can be damaged. In the best case it will reduce the life of the stove, in the worst case it will lead to fire.
- While the fuel in the fireplace is burning, the damper that regulates the draft in the fireplace should be ajar.
- Do not throw trash, painted logs, or pour flammable liquids into the fireplace. Smoke from such substances is toxic and can lead to poisoning.
Among all existing types of fireplaces the bio-fireplace is the last development. only this heating device doesn’t need any extraction in the furnace when there is a real flame.
The main element of bio-fireplace is the stainless steel block, in which ethanol (containing special additives of ethyl alcohol) is poured. During burning bioethanol does not emit any soot or smudge, there are no smells. products of burning are water in the form of steam and carbon dioxide. The case of biofires is usually in a high-tech style.
Sizes can be very different, from table models to floor corner, wall or freestanding. If necessary, the biomass module can be built into an existing wood burning fireplace portal, masking it with ceramic “firewood” or stones. before lighting, make sure that the chimney channel is completely closed with a damper, as the intense air movement will put out the flame in the biofireplace.
We are not talking about the thermal performance of biofires. they are designed solely for decorative purposes. You can install such a fireplace in any room, but you need to put a base of non-combustible materials of low thermal conductivity, t. к. The body of the biokanal will be heated. We should not take the flames in the biokanal as something safe. it’s real, and therefore can cause burns and fire if handled carelessly. published by econet.ru
