Beneficial properties of pine firewood
Today, briquettes, pellets and other types of fuel are used to kindle furnaces and fireplaces. But traditional firewoods continue to maintain their relevance. They are affordable, widespread and effective in receiving heat.
Firewood is often used for bath stoves and for home fireplaces. By the way, the latter in our time are more used not for heating space, but to create a cozy and harmonious interior.
Before making a purchase of firewood, you need to understand what wood breeds give more heat and are safe for heating devices. One of the popular types of wood is pine.
About the pros and cons of different firewood, it was already discussed in the article of firewood. good and different. But some nuances should dwell in more detail, what we will do now.
Different wood of wood has a different heat.intensive ability
If we compare the heat.intensive ability of firewood from various wood, then in terms of the mass (or, in other words, weight) it will be almost the same for everyone. But this is the calculation of the mass. But different breeds differ in different density, so with the same mass, the volume can be different. So it turns out that with greater density the same volume will be heavier, which means that it will provide greater heat. Understanding this, you can figure out which firewood is better to choose. We conclude: the heavier the woodpecker, the more heat it will give.
This, of course, is true only in relation to dry firewood. We do not talk about wet. they flare up more difficult than dry, and give less heat during burning. Only firewood from acacia (both dry and wet) burn in a preheated firebox almost the same.
Dry firewood burn hotter
- The record holder for heat.effectiveness. oak: 3.2 kcal/dm ²;
- Somewhere nearby there are ash, mountain ash, beech, apple tree, acacia-3.0-2.7 kcal/dm ²;
- Birch, maple, pear, chestnut. about 2.6 kcal/dm ² will warm you approximately equally;
- But pine, linden, alder will give only about 2 kcal/dm ²;
- You will receive even less heat from firewood from linden, willow and aspen. 1.8 kcal/dm ². They will burn quickly, almost without coal;
- fir and poplar will give 1.6 kcal/dm ².
It is better to choose wood firewood with dense wood
Can you burn pine in a wood stove? Is it okay?
If you got firewood from a rabor, then you are a happy owner of blessing fuel with a very high heat transfer. The roasts of the ancient Chersonesos were filled with grab coal. These firewood have always been valued among blacksmiths, founders, potter, bakers, because they burn for a long time and do not smoke.
If you are faced with a choice of ascinal or pine, not very rich in calories, then you should give preference to aspen. She, unlike a pine, leaving significant deposits on the inner surface of the chimney and the furnace, not only does not pollute them, but also helps to clean from these deposits, highlighting specific gases during burning. True, it is quite difficult to melt the aspen. There is even a saying: “Aspen does not burn without kerosene” 🙂 But it will not be at all difficult to throw in the already burning furnace.

Just like aspen, soften soot in a chimney alder firewood. They burn hot, almost not at all smoking. For these properties they were nicknamed the royal. They are very fragrant, so they are often used to smoke meat and fish.
Easily flare up and burn with even long flame birch firewood. They fill the room with a slight aroma (it is only a pity that after three years of storage it becomes less intense). Birch firewood, although they give good heat, but if the air is improperly, they can smoke to the firebox. And along with smoke, tar and birch resin are filtered into the chimney (it turns out, there is such a :)) tar abundantly settles on the pipe and can even drain down if the pipe is thin and cold, not insulated from the outside.

Where there are old fruit gardens, you can get hold of excellent thrummy. Firewood and pears are easily chopped, while burning well and fill the room with a pleasant aroma. “Tasty” smells and cherry firewood smell. But they smoke strongly when burning, because the cherry contains resins. For this reason, cherries and plum wood are better not to use for picnics.
Coniferous firewood. pine, spruce, larch
A characteristic crackling of logs in the fireplace, bright sparks, now and then scattering around. signs of burning coniferous firewood. Like birch, they give a lot of heat, only burn much faster. But for the unique resinous aroma, which is felt when the furnace with pine or spruce logs, you can forgive many shortcomings. Only now you will have to follow the hearth more carefully: the “shot” spark is able to fly out of the furnace and cause big troubles.
Coniferous firewood is appreciated for a unique resin.colored aroma
Spruce fires are not as hot as pine. keep in mind when the workpiece. Larch wood are used quite rarely. not so this breed of wood is common in our country. But if you come across such logs, remember: burning, they form a lot of carbon monoxide, so in no case do not rush to close the damper and take care of good ventilation. By the way, soot and soot from tarry conifers on the walls of the stove and chimney will settle no less than from birch.
Using a pellet burner for a furnace
Pellet burners are a universal device that fully automates the fuel supply process and supports the given temperature.
Today on the market you can find a large number of models that have successfully established themselves. They can work both using electric energy and using compressed gas. The first option is safer, since the supply of energy can be instantly limited in the event of an emergency.
An example of a pellet burner
An important feature of such burners is an automated fuel supply mechanism that does not require extraneous intervention. All that needs to be done is to enter the settings, check their correctness, if necessary, change them to the required indicators, and then only control the presence of fuel.
Modern pellet burners have several main parts, including:

- The transport mechanism of fuel supply;
- Ignition and control systems;
- Microprocessor for automated control of the combustion process;
- Actually the case.
Device and principle of operation
In a brick furnace
Installing a burner in a brick oven is quite simple:
- Actually, the burner body is inserted into the furnace, and then carefully attached with the help of screws and other materials.
- Typically, there are no gaps between the burn of the furnace and the wall of the burner, however, if there is a hole of large diameter, it is recommended to close it with specialized sealants.
- If the burner has electric power, then the power cable should be protected from exposure to high temperatures. Usually it is excreted outside the stove and direct impact of the flame, so the additional modification of the structure is not required.
- The last step is to fix the pellet storage on top of the burner. The case has a special mechanism, so you only need to install it in the appropriate grooves.
In a metal oven
The installation of a pellet burner on a metal stove is practically no different from a brick version. The only thing you should pay attention to is to prevent contact of the burner case with the walls of the furnace, since high temperature can lead to the failure of the mechanism.
An example of installation

Pellet loading technique
Drowning a simple brick stove with pellets is quite simple. If the burner has an electrical ignition mechanism, then you just need to press a special button. Cheaper models do not have such functionality, so a gas burner is used.
The fire rules are quite simple. you should evenly and slowly supply fuel. If a large amount of ash is formed, then the feed rate should be reduced, since pellets simply do not have time to burn, but they melt under the influence of high temperature.
What to do if you were brought wet firewood?
Wet wood burns poorly, does not give enough warmth and smokes very much. How to save the situation?
First, you need to cut and split the firewood. This is done if you were brought not chopped firewood. However, to save your own back, it is better to order chopped offsicals, although with this option it is easier to deceive the summer resident. It is more difficult to calculate the volume of firewood in the poll, and when they are laid in the logs, it is almost impossible to get money back or the missing busting of firewood. Therefore, experienced summer residents, in order not to be upset, as a rule, immediately laid down the shortage of firewood into the budget. And if, the fire is brought clearly according to the promised, then this is always a pleasant bonus.
Put the whole supply in a dry place. If you store on the street, cover with waterproof material on top: film, iron, plastic. In Polenitsa, birch firewood dries for about 3 months. The needles dry a little longer than birch.
Dry in parts in a house or in a bathhouse by a stove.
Next, dry the parties. While drown the stove, bring and put the flights near the stove. To accelerate the drying of the churbachka, fold each other, alternating rows with churbachka laid along and laid.laid lamps across. This will provide ventilation between them and accelerate the process.
How to store firewood
After acquiring firewood, they need to be folded in a place where they can maintain their properties for a long time. The place is prepared in advance. You can just fold the firewood under the canopy, as it turns out. But if you approach the process creatively, then from an ordinary logs you can create a real masterpiece and decorate the personal plot. So that the warehouse of logs does not crumble, they are often laid with a stack, relying in three sides into the walls of the buildings. You need to know that firewood will bring good heat transfer only if you store it correctly.
You should find the right place for storing logs, while you must follow certain rules when storing firewood:
- The logs must be placed not far from the exit of the house so that in winter it is convenient to go there for another portion of fuel in any weather.
- You need to saw and chop firewood not in winter, but in advance, before the onset of frosts.
- So that the firewood burn well, they need to be well dried. Then this condition is supported by a special laying of a logs.
- You cannot store firewood in the lowland, where the high level of humidity is. Firewood is again damp and can even bend. You can’t get pleasant aromas and good heat from such firewood.
- A canopy is installed on top of the logs, or laid in such a way that precipitation does not fall through the upper row into the log. over, they should be well ventilated, for this they withstand a certain distance.
To make the logs stable, you can do the laying “in the dressing”.
On a note. Woods sawn in winter are folded into a log in 4-6 months. Spring and summer blanks dry longer, 8-12 months. It depends on the weather, the level of humidity, the place where the firewood is dried.
Pros and cons of the pine firewood
People are heated by the room, the bathhouse with pine wood, but it is safe and correctly and is it right. The advantages of using such logs include:
- Obedience in cutting. Pine cut quickly along the fibers. With a split, everything is opposite. across the timber is easily sawn, along. too bad.
- Glued without problems;
- Based on the color and structure of timber, the pine is used both for the production of furniture elements with further applying varnish, and for frames, and any structures with decoration of veneer of solid rocks;
- Like coniferous, pine is distinguished by a pleasant aroma, distinguishes substances that have a therapeutic effect.
The disadvantages of such pine logs come from their advantages. The resin that supports the heat is considered the cause of the appearance of soot, which settles on the walls of the fire box and the chimney. This reduces the effectiveness of the heat unit, so you need to constantly observe its condition. In order to prevent the excess of soot, it is better to buy it to pine offships, aspen logs, as they clean the smoke and a firing box.
What are alternative options?
In addition to the above.listed wood varieties are popular briquettes from TOA. Their advantage is that they do not need to be injected, dried and in any other way to prepare for burning.
Instead of lump wood, you can use sawdust. But at the same time, firewood is still needed. With their help, kindling is performed, sawdust is added behind it, which should be no more than a third of the total volume of fuel.
Good firewood. What is it like?
So that any tree burns cleanly, efficiently and safely, it must meet several criteria that do not always depend on the breed.
Even wood firewood can be very bad if they are raw. Most of the energy will go to the evaporation of moisture and the release of a smelly poisonous creosot. Or on the burning of the resin:
Pine on drying
Determine whether a dry tree is enough, you can by eye in several ways:
- Cracks on the cut of logs can indicate dryness, but this is not the most reliable indicator. Some breeds may have cracks even with high humidity, and do not have them on dry firewood.
- The tree tends to darken when dried: from white/cream to different shades of gray and even yellow. At the acacia, I also noticed the opposite tendency-the fresh saw was yellow-green, after 3 months all the firewood “polished” until light gray.
- The knock “stick on the stick” will be “empty” and sonorous, wet firewood sounds dull, “filled”, “stupid”.
- Dry tree weighs much less moist.
- The bark holds tightly. firewood raw.
- Fresh sawing can be moist to the touch and have a rich smell.
- It is enough to set fire to a small chip. A dry tree easily ignites, wet hiss, smokes, stinks and is very badly falling asleep.
- According to the moisture meter, the humidity of the firewood should be within 15-20%, which is quite achievable if you start the workpiece no later than six months until the heating season.
P.S. The question with wood became relevant quite unexpectedly-her daughter and husband moved to a private house from odnushka-new buildings. The house is about 50 years old, until 1994 he was heated by a coarse stove, a rather unusual design (on my professional gaze of a city resident). The children decided to permararate and install a water boiler in it so that the firebox was more effective with firewood. So the “wood question” will be up more than once, as well as “stove”. There is already an experience of use, there will be something to share.
