Automatic solid propellant coppers of long burning. The advantages that automation gives to solid fuel boilers
Inability to connect to gas pipe became the reason for the popularity of heating devices powered by electricity, liquid and solid fuels. Traditionally, our compatriots choose solid fuel boilers, which are distinguished by their unpretentiousness and reliability.
The only problem with this equipment is the difficulty in operation. For continuous operation of solid fuels, it is necessary to constantly monitor the loading of the combustion chamber. It is impossible to leave the dwelling in frost for a long time, since when the boiler stops, the circulation of the coolant stops and the system can freeze. In this publication, solid fuel boilers with automatic fuel supply will be considered, which solved the problem of manual labor without losing efficiency and reliability.
The design and principle of operation of an autonomous boiler plant
This heating device is a design in the form of a boiler with a bunker, which plays the role of a warehouse for fuel. This "warehouse" can be made as an integral part of the thermal plant, or as a separate room. The storage of solid fuel built into the boiler plant can be structurally placed on top or to the side of heating device. The main advantage of the second option is the fuel supply, which is limited only by the size of the storage.
The fuel is moved from the “storage” to the fuel chamber by a loading mechanism, which can be screw or pneumatic. The feed mechanism is a pneumatic conveyor, which is a pipe through which fuel elements and pellets are pumped with the help of air.
The main advantage of this design is the partial energy independence of the system, since the fuel chamber is loaded only once every 24 hours. The disadvantage is the high cost of electricity during the operation of the mechanism and the noise of the pneumatic conveyor.
Screw feeding of pellets into the boiler furnace is the most common mechanism used in autonomous boiler plants.
The download speed of the camera is controlled automatically.
Important! Heating equipment of pyrolysis and direct combustion, working on pellets, coal and fuel briquettes, can be autonomous. wood boilers and other types of solid fuel boilers are not subject to automation.
Burner device and automation operation
In automatic solid fuel pellet boilers, a special burner design is used, the operation of which is associated with a fuel cell feed mechanism. The change in heating temperature occurs due to a change in the intensity of the fuel supply. The most complete combustion of pellets is carried out due to the forced air supply to the fuel chamber, directly to the combustion area. In modern models, a heated air flow enters the fuel cells, which allows the use of pellets and fuel briquettes with increased level humidity. Controls the flow of air and its temperature automatic.
Automation works as follows: when the temperature of the heat carrier set by the user is reached, the temperature sensor gives a signal to the automation unit, which, in turn, slows down the rate of supply of fuel elements to the burner.
Important! In the event of an emergency situation, the automation stops the supply of pellets to the burner, and stops the operation of the forced air supply fan, due to which the burner fades. Ignition of a flame is carried out in the automatic mode.
Advantages of solid fuel autonomous thermal power plants
By purchasing heating equipment with an automatic fuel chamber loading mechanism, two problems are solved at once:
- Increases the battery life of the boiler.
- There is no need for periodic maintenance of the equipment.
The second point is especially interesting, since the mechanism of automatic loading of the fuel chamber allows the boiler plant to function almost autonomously during the entire heating season. Automatic solid fuel boilers long burning represent an autonomous station in which all processes and operations take place without human intervention.
Selection rules
Autonomous solid fuel boiler plant must meet the following requirements:
- The performance needed to meet the needs of the user.
- Autonomy, which consists in working without human intervention.
- Reliability. The heating system should not be stopped, as this is fraught with failure of the heat exchanger and other heating equipment.
Tip: When solid fuels are burned, non-combustible solid particles (soot) are always left behind. Some of them, under the influence of natural draft, are carried out through the chimney outside the boiler plant. Some of it settles in the furnace and on the walls of the smoke exhaust system. Choose models that can independently clean the combustion chamber and chimney channels.
Modern autonomous thermal stations, in addition to full automation of the fuel supply process, control over combustion and coolant temperature, automatic ash removal devices, are equipped with an intelligent control system that is able to monitor weather changes and independently make adjustments to the operation of automatic solid fuel boiler. Comments are unnecessary!
By installing a solid fuel boiler with automatic fuel supply, several problems can be solved at once: increase the operating time of heating equipment and reduce the need for constant maintenance. In fact, autonomous stations are able to work without human intervention throughout the entire heating season.
How does an automatic solid fuel boiler work
An individual solid fuel automatic boiler is a completely autonomous thermal station. All processes, from ignition to the removal of combustion products, are carried out automatically.There are automatic TT boilers with varying degrees of automation. Fuel briquettes and pellets, as well as coal, are fed into the furnace by means of a vacuum or screw conveyor. Firewood is loaded manually.
According to the type of fuel bunker used, there are two main types of automatic boilers:
In addition to the fuel storage device, automatic boilers differ in the presence of a special burner device and a fuel supply system.
Burner device of automatic TT boiler
Autonomous solid fuel heating boilers with automatic fuel supply, use a special burner device, closely connected with the supply system. Automation controls the intensity and speed of fuel supply to the burner, and thus changes the heating temperature. Modern models operate in the boiler power modulation mode, ranging from 30 to 100%.Combustion is carried out under forced air pressure, which ensures a minimum percentage of underburning and ash residue. The burner device is equipped with movable grates. After the combustion of the fuel, the ash is poured into a special box.
The auto air supply system is also connected to automation. AT modern boilers, preheated air is supplied to the burner, which makes it possible to burn even raw materials with a high content of specific humidity.
When the limit temperature of heating the coolant is reached, the automation gives a signal to turn off. The fuel conveyor slows down its movement, maintaining a minimum supply of pellets to the burner. After the coolant cools down, the movement resumes in full.
Ignition is performed by the plasma method. The burner has an optical sensor that detects the presence of a flame. When the fire is extinguished, the automation gives a signal to re-ignite.
In the event of an emergency, the automation stops automated system fuel supply and gives a signal to turn off the fans, which leads to a rapid extinction of the flame in the boiler.
Methods for automatic supply of solid fuel
Household automatic solid fuel heating boilers use two main types of pellet feed to the burner:Each type of fuel loading has its advantages and disadvantages. When choosing, they are guided by the actual characteristics of the building: the remoteness of the storage from the boiler, the frequency of power outages, etc.
Which automated solid fuel boiler to choose
An automated boiler must meet several important criteria. The selected models are subject to the following requirements:- Reliability.
- Sufficient performance.
- Complete autonomy.
The most popular brands of boilers
It is believed that the best automatic solid fuel boilers are manufactured in the EU countries. AT recent times, domestic equipment is gradually winning the leading position.The popularity of a product determines the demand for it, reflected in the number of sales and reviews, positive or negative. The statistical reports received made it possible to compile an approximate rating of automatic solid fuel boilers, compiled, depending on the geographical location:
- Germany is the undoubted leader in the production of automatic systems and heating boilers. The quality of products is time-tested. Automation works flawlessly. The only thing that somewhat reduces popularity is the high cost, which, however, is fully justified. Heiztechnik and ThermoFLUX products are especially popular.
- Japan - Asian products are produced in the premium class. Automation has numerous additional functions that facilitate control and provide ease of use. One of the most popular models, with the maximum degree of automation, is produced by Kentatsu.
- Italy - among the products, FACI boilers are especially distinguished, having a beautiful appearance and fully comply with the requirements in force in the EU. Italian products are popular due to the adaptation of the internal structure of boilers to domestic conditions.
- Turkey - produces products in the middle price category. Boilers are offered by Termodinamik, Caldera Caltherm, Emtas. According to their characteristics, the products are almost identical to Russian counterparts, but inferior to them in quality.
- Russia - over the past 5 years, solid fuel boilers from Russian manufacturers have become truly high-quality equipment that can compete even with well-known European brands. According to a recent statistical report, the following models are especially popular: Obshchemash Valdai, Obshchemash Peresvet, Danko, Pereko.
- China - products made in the "Celestial Empire" do not differ in special build quality and reliability. You can stop your choice on only 1-2 models worthy of attention, thanks to the successful configuration and great functionality. Termal automatic stations are factory assembled and tested for ultimate loads.
- Serbia - not yet widely used and popular among domestic consumers, the products of the company Radijator, whose factories are located in Serbia. Boilers are traditionally manufactured in accordance with EU standards and undergo quality control.
The cost of automatic TT boilers
Modern types of automatic solid fuel heating boilers are a fully equipped and ready-to-work station, therefore, by default, they cannot be cheap. Models offered by a domestic manufacturer are offered starting from 80 - 100 thousand rubles.A little more expensive, it is Italian technology. A 15 kW household boiler can be purchased for 140 thousand rubles.
Japanese and German boilers cost about the same. The domestic consumer is offered to buy a station for 450-600 thousand rubles. The high price is quite justified, especially considering what specifications distinguish Japanese and German automatic TT boilers. In the course of work, about 30% of fuel are saved, start is carried out by pressing of one key. The boiler will work without stopping for a year.
Advantages and disadvantages of TT boilers with automatic loading
To form a real opinion and see all the advantages and disadvantages associated with the purchase of equipment with automatic loading, you will need to take into account the operating experience and feedback from the owners on the use of boilers.As cons, there are two main disadvantages:
- The complexity of the connection - it will not work to install on your own. Installation costs will be about 20% of the cost of the station.
- Energy dependence - the main disadvantage of automatic boilers is the dependence of their work on the availability of electricity. Automation is sensitive to voltage drops and fails at the slightest jump in the network. Therefore, the connection is made through
Automatic boilers for solid fuel long burning are an innovative product designed for generating heat and heating water. They are used for both residential and industrial premises of any size. The advanced control system of the device produces a certain amount of heat - it depends on the settings.
The operating time of the structure depends on its type. On average, the unit is able to work for about seven days with one load of fuel. Gray cast iron or steel can be used as a material, which is characterized by high strength and durability. This ensures reliable operation of the structure and long service life for many years. Such a device is purchased to obtain comfort in the process of use and save consumables every day. Reviews of solid fuel boilers for long burning indicate the importance right choice fuel.
"Smart" heating technology is easily adjusted so that the owner of the premises receives exactly the amount of heat energy required for comfortable work or living. A solid fuel boiler with automatic fuel supply is able to function without the participation of the owner.
Types of kindling for installation - how to choose fuel
Boilers top burning solid fuels can use various types of "food". Its calorie content is different, which affects the efficiency of the structure. If the client decides to purchase such a boiler, then the use of less "energy-intensive" fuel affects the change in the level of heat generation for the worse, depending on humidity.
Here are the main types of fuel:
- Firewood is the most common and relatively cheap commodity;
- Peat briquettes - an affordable type of fuel in Russia;
- Granules - due to the high rate of release of thermal energy;
- Anthracite is the oldest of fossil coals, which is characterized by high thermal conductivity;
- Coke is a solid product made by calcining coal;
- Brown coal - consists of peat and contains about 70% carbon.
Before purchasing one or another version of the boiler, you should pay attention to the type of fuel used. Most often, the manufacturer indicates the type of primary fuel that will provide the greatest amount of thermal energy. It is better to follow this rule in order to obtain maximum efficiency and make the process of heating the air comfortable.
What is the best fuel?
Solid fuel boilers can be fired in different ways and there are various types of such equipment. To select the best option, you should clarify the type of main fuel for the device - it can be a wood or coal boiler. If the manufacturer recommends using wood as the main type of "food", then its efficiency will be maximum. In the case of using secondary fuel, the efficiency of heat output can be reduced by 12 percent or more.
If you use briquettes, then they can be made from peat, straw or wood-type waste (sawdust, dust, and so on). Professionals recommend using only those briquettes that are produced by pressing. If this type of fuel in the combustion chamber breaks down into sawdust, then it is better to use it in combination with wood or coal. Pellets can be created from straw or a mixture of sawdust and wood dust. It is best to use pellets without bark or sand - these components interfere with the combustion process. It is better to lay firewood dry so that their consumption is minimal.
Attention should be paid to the appropriateness of the use of fuel and the purchase of a boiler. If the dwelling or business is surrounded by forests, then it is better to use firewood. If the house is located in a steppe area, you can purchase a boiler on peat briquettes. Professionals recommend choosing the most efficient fuel to get the best return at the lowest financial cost.
Types of aggregate in question
This type of device can be divided into two main groups:
- With an independent fuel supply system;
- Designs that require manual loading.
The self-feeding system uses pellet devices, which consist of granules. They are placed in unique containers that are located next to the device. Pellets are fed into the combustion chamber through the operation of the engine or auger. This design has a good efficiency indicator and is able to function without the participation of the owner for several days or weeks, depending on the specific model. The burning time is proportional to capacity and capacity.
Types of long-burning solid fuel boilers that use the manual loading method can be divided into three groups:
- Traditional - made of steel or cast iron;
- Pyrolysis - uses the method of wood decomposition;
- Long burn designs - can use fuel with 20% moisture content.
Each type has its own advantages and disadvantages. The most advanced device is the last type of boiler, which can be called more advanced and most efficient.

On device autonomous system heating and hot water supply, it is important to choose the right type of fuel to be burned.
Before buying a boiler, you need to decide on the type of fuel that will be profitable and effective for a particular case.
In non-gasified areas, solid fuel boilers have become popular.
Solid fuel boilers differ from gas and liquid fuel units in the supply of fuel. Due to the nature of the fuel, automatic feeding is difficult, so boilers burning coal, peat and wood mainly have a manual fuel loading mode.
To increase the time between fuel loads, long-burning units have been developed.
Long-burning boiler with manual fuel loading
The long-burning boiler burns fuel in layers. In this case, the level of combustion moves from top to bottom (as the top layer of fuel burns out, the flame moves to the lower layers). The frequency of fuel loading is from 2 to 7 days.
pyrolysis boiler
The most efficient solid fuel boiler is a gas generating unit.
Its operating principle is based on the decomposition of solid fuel into volatile components. This process is carried out through high temperature and oxygen deficiency.
The result is pyrolysis gas, which is burned in the second furnace. This design allows you to automate the combustion process (as in gas units).
Can't decide on a boiler? We made especially for you.
If, in addition to gas, you plan to use other types of fuel, a multi-fuel boiler is suitable for you, which you can read about.
About the specifics of piping boilers polypropylene pipes you can find out from the link.
Pellet boiler with automatic fuel loading
In order to fully automate the process of supplying solid fuel to the boiler furnace, the boiler is provided with a special bunker for storing fuel, a conveyor for its supply and a burner for combustion (fuel must be of the same size). Pellets were developed as fuel for such a boiler - dried and compressed sawdust in 50 mm granules.
Pellet boilers are equipped with an automation system that:
- provides supply and ignition of fuel;
- maintains the set temperature;
- protects against emergencies.
Solid fuel pellet boilers are able to work offline for a month. It is necessary to remove the resulting ash once every 2-3 days.
Features of solid fuel boilers with an automation system
- The temperature of the heat carrier is regulated by the intensity of combustion, which depends on the air supply to the boiler furnace.
- The control is carried out as follows: the temperature sensor sends an electromagnetic signal to the control mechanism and the air damper opens / closes.
- The air temperature in the rooms is controlled by thermostats and three-way valves.
- To compensate for pressure drops in the heating system, protection against pressure increase of the coolant and accumulation of air in pipelines, the boiler is equipped with a safety group ( expansion tank, safety valve with pressure gauge and air vent).
- To protect against overheating of the coolant, the boiler is equipped with protective sensors and cooling reserve circuits with natural circulation.
- The draft sensor stops the operation of the boiler when the intensity of draft in the furnace of the unit decreases.
- To ensure control over the operation of the unit and installation temperature regime, a control module is provided.
- When installing an additional GSM module, you can create a remote control and control the heating system through your phone or tablet.
The heating boiler must be safe, economical, efficient and automatic. The following factors influence the choice of a heating unit:
- Fuel consumption depends on the quality of the fuel (calorie content, humidity, ash content). But at the same time, high-quality fuel is more expensive. The intensity of fuel consumption changes in accordance with the temperature outside the window.
- The volume of the loading hopper affects the frequency of loading.
- The volume of the heated room determines the maximum output of the boiler. A unit with a margin of power is not cost-effective to use. The calculation is made according to the formula: 2 kW of boiler power for every 10 m2 of area.
- Two different boilers can burn the same number identical fuel, but one will heat the coolant better.
- For solid fuel boilers, the efficiency varies between 60-85%.
- The level of automation of the boiler provides offline work unit without human intervention.
