Homemade eternal log for the stove. Log "Chimney Sweep": reviews, instructions. Cleaning chimneys of stoves and fireplaces from soot. What determines the heat transfer of a wood-burning stove?

The article contains an interesting and effective way to organize a fireplace using logs. The article describes different methods for constructing a vertical combustion stove from logs. You will also find photo instructions for creating a wood burner with your own hands.

In the previous article, we talked about furnaces whose operation is based on the effect of pyrolysis (combustion of gases). Pyrolysis can also be successfully used to organize disposable stoves directly from fuel - wooden logs and 40-80 cm logs.

The described option has advantages:

• the ability to cook/heat food without additional (iron) devices other than a pot or frying pan;
• efficiency - one log burns for 3-4 hours;
• good light;
• quick organization - no need to collect thin firewood.

Along with the advantages, there are some characteristic disadvantages:

• you need evenly sawn logs or logs;
• in some cases a saw or wire is needed;
• disposability of the oven.

In the future, the advantages and disadvantages will be given in relation to other varieties. People call such a vertical fire a “candle.”

Method number 1. Finnish candle

This option is suitable if you can use a chainsaw. The log needs to be sawed through, dividing the cut circle into equal parts, ideally 6 parts. Do not make cuts all the way to the end, so that an untouched area of ​​the wood (“bottom”) remains. Then use an ax to split the core, add fuel (oil, gasoline, diesel fuel) and set it on fire.

Advantages:

• production time - 10 minutes, you can make several “candles” in one hour;
• safety - the bottom will not allow dry grass on the ground to ignite;
• the fire does not damage the soil even after complete burnout;
• high bright flame;
• gives a lot of warmth and light;
• portable design.

Flaws:

• burns quickly (2.5-3 hours);
• difficult to light;
• I need a chainsaw.

Method No. 2. Finnish candle-2

The log should be split into 4 equal parts to make equal logs. They need to be installed in their original form (in the form of a lump) and lit in the middle. You can pick up wood from your home woodpile.

Essentially, this is a smaller copy of the “three logs” stove. The principle is the same, the advantages and disadvantages are similar.

Method number 3. Three logs

Universal vertical disposable long-burning stove. To organize a fireplace, only three adjacent logs are required. Then you just need to light a fire inside the resulting well. After burning, the lumps can be moved closer to the center. This type of wooden stove combines all the advantages with virtually no disadvantages.

Advantages:

• simplicity of the device - no additional preparation of material is required;
• optimal balance of light and heat;
• burning time without adding fuel - up to 7 hours;
• sustainability.

Flaws:

• less wind resistance;
• The logs should be evenly split.

Method number 4. Primus

The most perfect and convenient way to organize a log stove. It gives a high concentration of flame and can be made in a “mini version” with a height of 20-30 cm. In order to organize a “Primus”, you will need several logs, and not necessarily from one log.

Operating procedure:

Cut the block to the specified size.

We divide it into 4-6 parts with an ax or saw or select suitable logs.

We gouge out the core and make notches (chips).

We connect the logs with wire so that we get a “well” inside. If the logs are large, you can make 2 of them shorter than the others. This will provide an influx of oxygen for pyrolysis during installation of the pot or pan.

The cold hearth before lighting should look like this:

Load the chips into the free space inside the stove.

Set it on fire and use it. Pay attention to the flame - pure pyrolysis combustion.

Larger options can be used for general purposes.

The optimal length of a log (chock) is two of its diameters. The ability to cook food and boil water is available for the first 2 hours after ignition, until the logs burn out.

How a disposable stove can be useful in the household

The main property of a wooden stove is the combustion of pyrolysis gases, which makes it an effective reactor when creating a stove in the yard, barbecue, cauldron or barbecue. A concentrated flame can be used to heat and roast metal or slaughtered poultry - pyrolysis combustion of 2-3 hours is a lot. A dense flame will melt cold lump bitumen or roofing material many times faster than a regular fire, and will replace a propane burner (portable version) in a vertical position.

The above-described principle of organizing a Finnish candle stove is an economical and convenient way to heat and create an impromptu camp or backyard kitchen. It can not only save time and effort, but even save lives in the event of an unexpected stay (overnight) in a remote area.

Friends, every day we analyze who gets to our website and for what search queries. And we noticed that the word DIY eternal log got a lot of requests. Accordingly, readers wanted to find this information on our website. Maybe this is due to the fact that we have articles that describe products made from logs, stumps, saw cuts and they think that this also applies to us.

We decided to study and describe in this article what kind of wonderful log this is, which will help you save on heating costs and how to make it yourself, especially since there are a lot of negative and positive reviews on the Internet.

The device of an eternal log is shown in the diagram below.

This is not a log, but an ordinary metal pipe, welded on both sides. There is a hole in the pipe that can be closed using a valve. Water is poured through this hole and fills the entire volume of the pipe. Several small holes were also made along the entire length of the pipe. Accordingly, to prevent water from pouring out through these holes, legs were made.

According to the inventor in the video, this eternal log is an endless source of savings on heating and will work for a long time.

It is also said that the stove will work more efficiently.

How does it all work? Water is poured into the pipe, preferably hot, so that heating is faster, but cold is also possible. You can insert a funnel into the hole to ensure that the water gets into the hole accurately. With hot water, the full effect of the formation of saturated steam begins faster.

Physics

1. The burning time of firewood increases significantly, for example, without an eternal log, burning lasts on average 1 hour 10 minutes, and with it - 1 hour 40 minutes, that is, 40% longer. It turns out that to heat a house or room, you will need less firewood.
2. The heat capacity of steam is twice as high as the heat capacity of surrounding air. This is indicated in the reference book “Specific Heat Capacities of Solids, Liquids and Gases”. The specific heat capacity at constant pressure for air is 1 KJ/kg*K, and for water vapor it is 2.14 KJ/kg*K at 100°C.

After you have filled in the water, close the hole with a stopper and place the eternal log at the very bottom of the stove. Place regular logs on the left, right and top, add kindling and set it all on fire.

After some time, the water boils and steam is formed. Then air and steam are mixed inside the stove and a mixture is formed, the heat capacity of which is almost twice that of ordinary air.

Watch the video: Eternal log - saving on heating up to 50%

In the end, is this a myth or reality?

What can we say about this? All this, of course, is not true, the laws of physics have not been repealed and the law of conservation of energy still exists. Accordingly, in order to obtain additional energy in one place, you need to spend this energy in another. You also always need to make sure that the holes are always open, otherwise a water hammer may occur and the entire firebox will turn around.

There is only one piece of advice - a well-built stove will save fuel and keep the heat for a long time. But to do this, you need an experienced village stove maker who can determine the volume of the house and build a stove of the required size.

What can you use to heat a stove?

Fireplaces and wood stoves are rarely used for heating in modern homes due to the fact that high-tech methods of maintaining heat are much faster, more convenient and do not require as much physical effort. But, despite this, fireplaces do not lose their popularity, creating a unique spiritual atmosphere in country houses or city apartments.

One of the important procedures to ensure the safe use of a wood stove or fireplace is regular cleaning of the chimney. This must be done regardless of the design of the chimney, through the wall or with an exit through the roof. Why should the chimney be cleaned and how often should it be done? How effectively can this procedure be carried out using the Chimney Sweeper log chimney cleaner?

Why do you need to clean your chimney?

To understand why it is necessary to clean the chimneys of stoves and fireplaces from soot, first of all, you need to know what happens in the chimney when using any type of solid fuel material, including firewood. When a fire burns in a fireplace or stove, so-called combustion products, soot and soot, are actively released. All this, together with the smoke, goes up, directly into the fireplace chimneys and settles in a soft, greasy layer on the walls of the chimney. The more time has passed since the last cleaning, the less space there is left for exhausting smoke and

Of course, proper operation, as well as adherence to simple principles for selecting firewood for a stove or fireplace, can significantly slow down this process:

• There is no need to burn anything in the stove (fireplace) except wood. It is better to try to dispose of any household waste, even paper waste, in other ways.
• Choose firewood exclusively from wood species that contain a minimum of resins. This is, for example, dry wood of alder, aspen, oak, and birch. Firewood from fruit trees, which is so loved for the amazing aroma released during combustion, is slightly worse in quality. Experts consider coniferous trees to be outsiders on this list because they emit large amounts of soot due to their high content of natural resins. It is also not recommended to often use poplar and willow, which are not the most expensive but quickly burn out.
• Don't forget about regular cleaning of the blower.

Compliance with all of the above, together with prevention, will allow you to avoid serious chimney blockage for years. But, despite this, cleaning the stove (fireplace) pipe still cannot be avoided. In addition to settling soot, a blockage can form from the outside if debris or a foreign object gets into the pipe. Therefore, professionals involved in chimney repair and cleaning often recommend checking the chimney pipe in the fall and spring.

How do you know when your chimney needs cleaning? The first sign that the procedure cannot be postponed will be a visible deterioration in cravings. The release of the main amount of smoke and smell not through the chimney, but into the room, sparks flying from the fireplace is a signal that the chimney is dirty. Slow and insufficient draft not only creates smoke, but can also lead to intoxication with carbon monoxide components. In addition, a spark flying from the fireplace can cause a fire or injury.

Why else is a contaminated chimney pipe so dangerous? Ignition of accumulated soot can easily lead to cracking and destruction of the chimney walls. The conclusion that can be reached based on all of the above: cleaning the chimney is an important procedure, the thoroughness and regularity of which determines the good operation of stoves and fireplaces, as well as the safety of the home.

Cleaning methods

Depending on the means used to clean the chimneys of stoves and fireplaces from soot, all methods for removing dirty sediment from a chimney pipe can be divided into three groups:

• The oldest known method is mechanical, also known as traditional chimney cleaning. The procedure is carried out using special “chimney sweep tools”: various brushes and a “core”, a cable with a heavy load to break through the blockage. Despite the outward primitiveness, such cleaning of soot from chimneys of stoves and fireplaces gives the best effect and allows you to cope with the most advanced types of chimney pipe blockage.

• Thermal cleaning is also a fairly old method that has been proven over the years. It consists of “burning out” the soot by heating it with well-dried pine wood. Technically, lighting a fire and waiting for the result is the easiest and least expensive way. But it is also the most dangerous: with a large accumulation of soot, a fire in the chimney is practically a small explosion. A pipe, especially one made of brickwork, that has small cracks may simply fall apart. Therefore, experts advise using this method only as a preventive measure, provided that a large amount of soot and soot has not had time to settle in the chimney pipe.

• Chemical (non-mechanical) cleaning. When considering the use of such a product as a “Chimney Sweep” log for cleaning a stove (fireplace) chimney, reviews of which can be found on most construction forums, it is worth taking a closer look at chemical methods. The use of chemical properties of substances to dissolve or dry soot in a chimney began many decades ago, with the so-called folk remedies. For example, the most famous life hack, invented by our great-grandfathers, is burning potato peelings. Also, the chimney was often cleaned by pouring ordinary salt onto the hot firewood. Today, along with folk remedies, a huge number of modern products from chemical laboratories have appeared in stores, designed for cleaning chimney chimneys in a non-mechanical way. Such products are produced in the form of pressed bars (or logs), as well as in the form of dry powdery masses. What distinguishes modern “chemistry” from traditional methods is the need to strictly follow the instructions and adhere to the dosage, as well as a smaller amount of substance used at a time.

Chemical cleaning products include the Chimney Sweep log, which is often recommended on construction sites on the Internet. What is this product and how should it be used to effectively get rid of soot deposits in the chimney?

Log "Chimney Sweep": what is it

What is a patented non-mechanical chimney cleaning product? Its brand name is “Log Chimney Sweeper” (reviews of this product are given below). Externally, it is a pressed block, measuring 25x8x6 cm, wrapped in a protective paper wrapper. Sold in original packaging containing product information and procedure instructions.

The product is recommended for cleaning stove and fireplace pipes of any type, even those of complex design, such as a curved chimney through a wall. The substances that make up the logs, when burned, release volatile chemicals that enter the chimney along with smoke and hot air and affect the layer of soot accumulated there. As a result of this, the contaminants in the pipe dry out and fall off the walls of the chimney.

The Chimney Sweeper log is intended for fireplaces or stoves using coal or wood raw materials. It is strictly forbidden to use this product in ovens equipped with special devices, as well as those operating on gas or electricity.

Important! The question often arises as to whether a product such as a Chimney Sweeper log can completely replace mechanical cleaning. Reviews from professionals about this product warn: such cleaning can only be of a preventive nature. Using logs for a long time eliminates the need to contact a specialist who cleans the chimney. However, it is not possible to completely abandon mechanical cleaning.

Composition of the “Chimney Sweeper” product

The Chimney Sweeper log is declared by the manufacturers as a product that is safe for humans and pets. In the composition of artificial logs:

• Coal wax (small content of coal dust).
• Natural wood sawdust.
• Natural substances: urea and amorphous silica.
• Ammonium sulfate is a substance that is essentially a compound of sulfuric acid and is actively used for industrial needs. Including for the purpose of disinfecting water in city water supply systems.
• Sodium sulfate (anhydrous), another commonly used sulfuric acid compound (sodium salt). In addition to industrial purposes, this substance is officially a food additive, and was previously used in pharmacology.
• Substances in the composition that may cause concern - and in concentrated form - are both contraindicated for contact with the mucous membranes of the eyes and human skin. Therefore, there is no need to remove the log from its protective paper casing. It’s even better to protect yourself with regular rubber gloves.

Preparation for the procedure

To ensure safety, before cleaning the chimney using Chimney Sweeper logs, you should carry out preparatory steps.

First of all, you need to inspect the chimney to check if the pipe is clogged with foreign debris. If a blockage is detected in the chimney, the use of logs should be abandoned in favor of a mechanical cleaning method.

Is it necessary to put firewood together with Chimney Sweeper logs?

The use of the “Chimney Sweeper” product is completely acceptable without “support” in the form of coals or wood firewood. However, hot coals left over from the previous fireplace firebox (stove) or dry firewood placed before cleaning the chimney using a Chimney Sweeper log will significantly enhance the effect of using this product. When cleaning the chimney with a “Chimney Sweeper” log in combination with firewood (coals), a block of the product is laid out on top.

Forbidden! Burn more than one log in combination with hot coals.

Instructions for use

How to use the Chimney Sweeper log correctly and safely? The instructions are located on the branded packaging of the product:

• Remove the log from the original packaging without unwrapping the protective wrapper and place it in the firebox. Burn the paper wrapper on both sides.
• In a closed oven, you should close the door flaps; in a fireplace, use a protective grill.
• Wait until the bar burns completely (about 90 minutes).
• The remains (ash) of the bar should be left in the fireplace for the entire period of use, about 1-2 weeks. During this time, you can use the stove (fireplace) as usual.
• After the procedure, it is recommended to ventilate the room.

Last stage of cleaning

You will need to thoroughly clean the stove (fireplace) two weeks after using the Chimney Sweeper log product. During this time, all active substances will have time to have the maximum possible effect on deposits in the chimney. The soot, softened under their action, falls down.

At this stage, it is important to remove the fallen soot from the chimney pipe elbow, the smoke damper firebox and other accessible elements of the fireplace (stove); the chimney will need to be inspected again. Cleaning is especially necessary for fireplaces with curved chimney channels, otherwise remaining soot may clog the chimney.

To remove cleaning waste, tools that are accessible to everyone are well suited: a vacuum cleaner and a regular fireplace brush.

How much product is needed for one cleaning?

Another question that may arise for a person using the Chimney Sweeper for the first time: how many logs should be burned at a time for more effective cleaning? Manufacturers recommend burning one log for regular cleaning, and two logs for wide chimneys, but one after another, not simultaneously. Laying two logs in one burn is allowed for the first cleaning or removal of a large layer of settled contaminants. But this should be done carefully, observing all fire safety measures.

How often should cleaning be done using Chimney Sweeper logs?

The manufacturer of the Chimney Sweeper recommends that you carry out the cleaning procedure regularly, at least twice a year. The frequency of cleaning largely depends on how often the stove or fireplace is used. For example, if the fireplace is lit once daily, it is enough to carry out preventive cleaning twice a season, using one block each time. If the fireplace (stove) is lit no more than once a week, one log for the heating season is quite enough.
