Unfortunately, not everyone can boast of having blue fuel in their home. For this reason, boilers of long burning on wood become quite popular. They have a simple design, have a huge number of advantages and can be designed with your own hands. Consider the features of the presented device in more detail.
Device Overview: How It Works
So, boilers for long burning on wood are heating appliances of a special design that allow you to completely heat the required area and at the same time significantly save fuel. They can be installed both in residential private houses and in enterprises. The main thing is to choose the appropriate characteristics of the device.
Boilers for long burning on wood have a fairly simple principle of operation. The design of the apparatus includes a heat exchanger, a chamber for burning fuel, an ash pan. Also, for this type of apparatus additional details are characteristic that provide an air flow from outside. In this case, fuel is significantly saved. The fact is that it does not burn, but smolders very slowly.
Device specifications
Solid fuel or wood burning boilers have certain technical features:
- The temperature mode of operation is 70/50 or 60/45 degrees.
- Efficiency - up to 80%.
- Functioning without interruption - 12-15 hours.
- The frequency of cleaning the ash pan - once a week (with constant work).
These key features will help you figure out whether to buy such a device. Naturally, you should also consider the advantages of the unit.
Device advantages
Boilers for long burning on wood have several advantages:
1. High efficiency and productivity. The device is able to provide good thermal return. They are very productive even in those areas, the size of which reaches 200 square meters. m
2. The simplicity of the design. You do not need special knowledge to operate the device or to care for it.
3. Fuel availability. In addition to firewood, you can use pellets, coal or sawdust briquettes. This saves you extra money.
4. Environmental safety. For the operation of the device, natural material is used.
5. Profitability.
6. Autonomy. Many device models do not require a connection to an electrical network or other equipment.
7. Durability and reliability.
8. Duration of continuous operation.
9. Durability. Such a design can last at least 15 years.
disadvantages
Unfortunately, they also exist. The Boran long-burning wood boiler (or other model) has the following disadvantages:
- Enough large dimensions.
- Not a little weight. The fact is that some parts are made of cast iron. This makes the boiler more durable, but very heavy. Naturally, in this case, the installation location is limited.
- Today, firewood is becoming more expensive fuel.
- Periodically, the fuel chamber must be replenished. That is, you must monitor the combustion of firewood. Otherwise, the boiler will simply go out. The frequency of adding solid fuel is on average once every 3 hours.
- Some models are dependent on electricity. If it is not, then the device simply will not work as it should.
- The need to equip the chimney.
How to choose the right product?
A real boiler for long burning on wood works quite efficiently. However, you need to choose the model that will satisfy all your requirements. Try to pay attention to such criteria:
1. Camera to download. If it is large, then you will have to load it less frequently with fuel.
2. The air supply mechanism. Naturally, an electric motor is more efficient. However, this makes the boiler volatile.
3. Features of the design. You can choose a device that will be additionally equipped with a water tank.
4. The method of adjusting the intensity of smoldering firewood. Most often, a mechanical thermostat is used for this .
5. Type of own heating system. It depends on which outputs should be in the unit.
Naturally, before buying, you should carefully study the reviews of other users about the selected model. You need to purchase the unit only in licensed stores that can present all the necessary documents for the goods.
Features of self-construction
It is relatively easy to make a boiler with long burning wood with your own hands. However, this process has certain features. First of all, be sure to try to draw an accurate outline of your future creation on paper. Make all the necessary calculations here. At this stage, it is advisable not to be mistaken, because the effectiveness of the tool depends on correctly performed calculations. Naturally, you can use ready-made drawings.
Next, you need to collect all the necessary material and tools. Note that you can even use improvised tools. However, there are parts that will have to be purchased at the store. This applies to the air supply system and other elements. Naturally, the apparatus should be equipped so that it is stable, in a safe place.
What materials and tools are needed to work?
It is not difficult to make a boiler with long burning wood with your own hands. First you need to collect all the necessary components and devices:
1. Reinforcement, bricks and concrete (for the manufacture of the foundation).
2. Water tank made of stainless steel or galvanized.
3. Metal pipes for connecting the tank.
4. Doors for ashpit and firebox.
5. A metal barrel or steel pipe. In the first case, the volume of the vessel should be 200 liters. As for the pipe, it is advisable to choose a product with a diameter of 50-80 cm, as well as about 1 m long.
6. Metal corners and steel sheets with a thickness of 5 mm.
7. A circle 5 cm thick that will separate the ash pan from the furnace.
8. The welding machine.
9. Drill and screwdriver.
10. Fasteners (for doors).
11. Scissors for metal.
12. The Bulgarian.
You may have to prepare some more tools. You will already think about this during the manufacturing process.
Manufacturing Features
If you decide to build boilers for long burning on wood, do-it-yourself assembly involves several stages:
- First, prepare the central part. Divide it into several chambers using metal circles. The largest capacity should be the firebox. Use a welding machine to fasten the elements. Such chambers should be located in the pipe: combustion, complete combustion, and an ash pan. Immediately cut out the doors for the first and last containers.
- In order for systematic pressure to be applied to the wood, it is necessary to fix a special disk inside the chamber equipped with blades. Note that a hole with a diameter of 4 cm should be made inside it. Note that the volume of the bounding circle should be several cm less than the volume of the body.
- Steel pipe of smaller diameter should be fixed in the upper part of the stove. It will serve as a chimney.
- Now you can weld all the pipes and taps to the furnace, through which the device will be connected to the heating system.
- Additionally, you can equip the boiler with a special water “jacket”, which will help cool the combustion chamber. It is placed between the walls of the furnace (if they are double).
- Lastly, install on the device all the necessary devices to control the power of the product, air supply. Then the doors are attached.
Now it remains only to install the device correctly.
Self-installation of the device
A self-made water- fired long-burning stove made of wood should be properly mounted. In order for all manipulations to be performed correctly, you must adhere to certain installation rules:
1. First of all, you need to make the basis for the product. Naturally, the installation location should be suitable. Try to mount the boiler in a room where combustible materials are not stored. It should be well ventilated. It is advisable that small children do not have access to this room.
2. For the manufacture of the foundation, you can use bricks and high-quality concrete. The base is necessary so that the structure is installed evenly. Moreover, the presented boiler has a fairly large weight.
3. All joints must be pre-tested.
4. After connecting the heating system, the boiler can be checked. If everything is in order, then the installation has occurred correctly.
If you are not confident in your abilities, it is better to entrust this work to specialists.
Useful Tips
A long-burning wood-burning boiler is a unique heating device, the advantages of which we have already considered. However, before manufacturing, read some useful tips that will help you design a truly effective device:
1. All calculations must be accurate and correct. The smallest mistake can lead to the fact that the quality of work will significantly decrease.
2. After filling the fuel into the chamber and setting it on fire, the door must be closed. This is necessary to ensure not quick burning, but smoldering of the material. Heat enters the system.
3. A long burning wood burning boiler must have a large loading chamber so that it can be loaded tightly with fuel.
4. Do not mount such a device where explosive and combustible substances are stored.
That's all. Be careful and careful when making this device.
