Small solid fuel boiler 14 kW

Despite the high level of gasification, the possibility of connecting the main gas is not everywhere, and solid fuel boilers continue to be in great demand among owners of private houses.

Low power solid fuel boilers

To small heating boilers solid fuel boilers include boilers with a capacity of 7-12 kW. They are compact, lightweight and easy to use. Some models are equipped with hob for cooking and heating food, which makes them an indispensable assistant in a small country house.

it floor-standing boilers, most often equipped with one heating circuit.

The following is used as fuel for the boiler:

• Brown and black coal;
• Coke;
• Firewood;
• Pellets;
• Fuel briquettes.

When planning the purchase of a small boiler for a private house or summer cottage, first decide which fuel will be mainly used. The further correct choice of a compact solid fuel boiler will depend on this. If it is firewood, then it will be preferable to choose a bottom combustion system. Typically, such a boiler is equipped with 2-3 combustion chambers, the fuel in them burns almost entirely. Low consumption of firewood, low level of emission of combustion products into the atmosphere, distinguish this boiler model from other combustion systems. A boiler of this kind allows you to control the combustion process by regulating the volume of air entering directly into the combustion chamber.

Top combustion systems are more commonly installed when coal is selected as the primary fuel for the boiler.

Such boilers are made from the following materials:

• steel;
• cast iron.

Steel boilers differ from cast iron boilers of the same manufacturer in lower cost, but at the same time with a relatively short service life and a non-separable design.

How to properly install a solid fuel boiler

The height of the ceilings of the room where the boiler is planned to be installed must be at least 2.2 m, the volume of the room must be at least 8 m³, the room must be equipped with an opening window with an area of ​​more than 0.7 m². Great importance has a ventilation system of the room and a fire decoupling. During installation, it is necessary to provide a separate outlet for the flue duct.

Pay special attention to the organization of the chimney. It must be insulated. The height should be at least 6 m. Keep in mind that cast iron is unsuitable for a pipe - it cracks quickly.

The weight load is small, does not exceed the load level permissible according to SNiP per unit of floor area - 250 kg / m²

The efficiency of such a boiler can be easily increased by installing in the heating system circulation pump.

Buying small solid fuel boilers, you really get the opportunity to provide the house with heat at minimal financial costs.

Each of these modifications has both advantages and disadvantages. For example, electrical household boilers heating are safe, low level noise and lack of exhaust gases. At the same time, they consume a lot of electricity, which leads to high heating costs. Gas and liquid fuel household heating boilers are also quite expensive to operate and maintain. In this regard, solid fuel equipment is becoming increasingly popular.

Solid fuel household heating boilers are among the most environmentally friendly and unpretentious. They can successfully work on coal, wood and other types of fossil fuels. The main advantages of such equipment are low heating costs, automatic temperature maintenance and ease of use.

In addition, the Vienybė household solid fuel heating boiler is distinguished by long-term operation without refueling (up to 16 hours), a high degree of automation and an efficiency of up to 90%. The safe operation of Vienybė equipment is ensured by the presence of a safety valve.

Installing a solid fuel boiler is one of the best, and sometimes the only one possible variant heating houses that are located in an area without centralized gas supply. Alternative - electric heating, for example, cannot be used in country houses and cottages, since the power supply system available in horticultural societies is not designed for such a load. Such a solid fuel boiler is convenient and economical. Firewood, coal, wood waste, briquettes, pellets are suitable for him - everything that the owner of the house can and considers it necessary to prepare.

Features of the device of solid fuel boilers

The boiler drum can be made of cast iron or steel. The advantages of steel boilers include their lower cost and lower weight, as well as better resistance to changes in body temperature. A significant drawback is a shorter service life. Sooner or later, the body of the high-temperature chamber burns out. The advantages of solid fuel boilers made of cast iron are strength and durability, the disadvantages are high weight and increased sensitivity to rapid changes in temperature conditions. If the temperature of the heat exchanger drops sharply by at least 20 ° C, its sections may collapse. This feature should be taken into account when designing a heating system.

An important factor is the presence or absence of an electronic combustion control system and forced circulation of the coolant. Boilers equipped with a control unit and an electric pump are more economical, but volatile. In the event of a power failure, the electrified solid fuel boiler will be shut down. A simpler one - a non-volatile boiler does not need electricity. However, such units have a slightly lower efficiency, and in order to organize the movement of the coolant, they need a "gravity" system - a pipe structure large diameter installed with a certain slope.

Pyrolysis boilers long burning

The most advanced, efficient and economical are solid fuel boilers with a stove, the design of which allows for pyrolysis combustion of wood fuel - firewood, pellets, briquettes or woodworking waste. The only requirement for fuel is that its moisture content should not exceed 20%. Pyrolysis is a process of high-temperature decomposition of wood under conditions of limited oxygen supply, in which the feedstock is converted into wood gas, coal and tar.

Coal and tar smolder in the furnace, providing the temperature necessary to maintain the pyrolysis process (on average 400 ° C - 500 ° C), and the resulting wood gas is fed through a nozzle into a special high-temperature chamber, where it mixes with air and burns with a large heat release. The main advantages of pyrolysis boilers are unprecedentedly high efficiency and long-term fuel combustion, which provides the possibility of autonomous operation for 14 - 24 hours. The main disadvantage is high price and dependence on the supply of electricity, since many models are equipped with automatic systems for regulating the combustion mode.

Pellet boilers

According to experts, one of the most significant disadvantages of most types of solid fuel boilers is the inability to maintain a constant combustion temperature in them. The use of coal and firewood of different quality and moisture content does not allow stabilizing the heating temperature of the carrier, which negatively affects the efficiency of the heating system. Boilers that are designed to use special granular fuel - pellets - are devoid of this drawback. Fuel for such boilers is made in Moscow, from woodworking waste, peat and residues from the processing of certain types of agricultural products.

The feedstock for the pellets is crushed, dried and compressed into elongated granules under high pressure standard size... Stabilization of the combustion process and temperature conditions in pellet boilers is ensured thanks to the controlled automatic fuel supply from a special bunker. In the most advanced models, the automation is capable of cleaning the combustion chamber from soot and ash. Standardized fuel consumption allows you to accurately assess the need, and timely purchase the required amount of pellets. All pelletized boilers are economical and extremely efficient.

Many villages do not have a gas pipeline, and paying electricity bills can cost a pretty penny. Of course, this is annoying, but there will be no problems with heating even in this case. Using a solid fuel boiler will allow you to forget about the inconveniences associated with the cold, even if it is severe frost outside.

Is firewood out of date?

Of course, in an age of ubiquitous automation, nanotechnology and technology that staggers the imagination with its capabilities, it is difficult to believe that the use of solid fuel for heating it is advisable.

But just imagine, such a boiler is not just a "stove-potbelly stove" into which you have to constantly throw firewood. This is the real center of the heating system, efficient, economical, at the same time inexpensive and durable.

Principle of operation such equipment is extremely simple. You can use shavings, briquettes, pellets, even corn sticks and seed husks as fuel for different models.

The design features of the firebox are such that not all firewood begins to burn intensively at once, but only the top layer of fuel. At the same time, its consumption is reduced significantly, which implies significant savings.

The water that circulates in the heating system enters the heat exchanger, which is heated by the energy of the burning wood. When all the coolant warms up to the required temperature, the boiler turns off.

After connecting the unit to the water supply system and loading fuel, it can work for quite a long time without the user's attention. This time depends on both the quality of the fuel and its quantity. For example, briquettes, husks or spruce shavings burn out quickly enough, which means that it is often necessary to remove ash and load a new portion of fuel in order for the boiler to continue heating. Coal and anthracite burn longer, and often the energy they release during combustion is higher. This means that working on this type of fuel, the boiler will heat up stronger and longer.

Fundamental differences

In order to make the choice of a boiler not difficult, we answered several popular questions that arise from buyers.

Are there any differences in the principle of operation and the fuel used?

Traditional devices work only on wood, coal or peat briquettes. They are completely independent of electricity, which makes them very popular with summer residents and owners of country houses. The only thing worth thinking about is the constant availability of fuel, that is, firewood, coke or coal. Such boilers perfectly maintain the set temperature, and for many years they do not give any malfunctions.

Pyrolysis boilers can "boast" of a very high efficiency. Their main difference from traditional ones is in the use of not only heat from fuel combustion, but also the energy released wood gas... Special fans heat the air in the combustion chamber to a very high high temperatures, firewood begins to emit gas, this process is called pyrolysis.

It is worth noting one more advantage of such devices - during operation, neither soot with soot nor ash is practically formed.

In addition, there are also, in which special pellets are used as fuel - compressed wood. The advantage of such units is that they independently add granules to the furnace using a screw.

Purchase long burning boilers , this is perfect solution for heating large areas, such as private houses or roadside hotels. They can be versatile (coal and wood-fired), or wood-based. These units are very sensitive to the quality of the materials that the user sends to the combustion chamber. Therefore, we advise you to abandon damp firewood.

Manual or automatic fuel loading?

Wood chips, coal or peat will have to be thrown into the furnaces of traditional, pyrolysis boilers or long-burning devices. In doing so, do not forget to periodically check the presence of fuel in the combustion chamber.

Automatic boilers , only calibrated charcoal is used as fuel, which is fed into the furnace, as in pellet boilers, using augers. Such a design will facilitate the work of servicing the boiler, but from time to time it is still worth "visiting" it.

Does the material of the heat exchanger matter?

Are gaining more and more popularity boilers made of steel ... If your choice fell on a similar model, you can be sure that this equipment will serve for a very long time. Steel perfectly conducts heat, in the event of a leak, it is easy to solder it, and carbon deposits practically do not form on it. But this material is not resistant to the formation of condensation, which means that corrosion is possible.

Cast iron boilers - classics, but now they are gradually becoming a thing of the past. Despite the fact that the material from which the heat exchanger is made perfectly conducts heat and is almost 100% protected from rust formation, it has a number of disadvantages. Experts warn about the complexity of implementation renovation works- it is almost impossible to replace the cracked section due to the formed carbon deposits.

What is the best chimney design?

In fact, several factors affect how the ventilation pipes that remove the combustion products will run.

At first, thrust... In this case, it is an indication of the speed at which the smoke will be removed. If you notice that smoke accumulates in the room where the boiler is operating, you need to open the damper and thereby increase the air flow.

Secondly, chimney section... This parameter always depends on the design features of each boiler model. But, it is worth noting that too narrow a chimney may not cope with the entire volume of combustion products, especially if the unit is powerful. And in too wide air will “walk” without taking with it unpleasant odors and fumes.

Speaking about design, it should be said right away that only specialists can do this, because it is important to know the aerodynamic features of the heating system, the boiler itself and the chimney. It can be square or round. But, keep in mind, the structure should not have a very large number of bends, irregularities and turns. By the way, in round chimneys, the draft is always better (since there are practically no obstacles to the air flow).

A solid fuel boiler is an ideal solution for heating a private house, especially if it is not possible to use gas or electricity. This equipment is capable of heating a large volume of water in heating system, so it will be warm even in a large room. Check how convenient it is to use economical, inexpensive fuel, and feel the result of the boiler operation within a few minutes after turning it on.

If we talk about modern heating devices and the principles of their operation, then one cannot fail to note such equipment as solid fuel boilers. As their name implies, they function using the energy of solid fuels. These innovative devices not only effectively heat the living space, but also perfectly fit into the interior and create comfort in any home.

However, not everyone can clearly say which solid fuel boiler is better. Therefore, it is necessary to determine how to choose a solid fuel boiler that best suits a particular room in terms of its performance and efficiency indicators and is distinguished by its reliability and long service life. This is what will be discussed further.

Fuel types for boilers

So, thanks to innovative technologies heat can be obtained from almost any source, which provides a unique opportunity to save a significant part of financial resources and save yourself from the need for regular purchases of expensive fuel.

• coal fired samples... Not knowing how to choose a solid fuel boiler for a house located far from a large settlement, special attention should be paid to just such a mechanism. These boilers are perfect if there is no way to ensure proper storage of firewood. At the same time, the performance of such equipment will be very high, and its device will not become too expensive. The main advantages of a coal-fired boiler are its versatility, low cost of consumables, and the ability to work autonomously;
• pellet boilers and wood fired boilers... The principle of operation of a solid fuel boiler of this type is based on the use of wood and pellets (special fuel pellets) as the main source of heat. The power of these mechanisms is quite high and can reach up to 200 kW, while they are economical and can be installed in any room.
  
  The availability of wood explains the widespread popularity of these devices among the population. In addition, the efficiency of a solid fuel boiler operating on wood is high and reaches 90%. Wood and pellets burn for a long time without leaving behind any harmful products;
• pyrolysis boilers... The work of these boilers is aimed at burning solid fuels on a biological basis, which can be wood pulp. These substances, when burned, emit a special combustible gas, thanks to which the heat transfer is so efficient (the efficiency of pyrolysis boilers is from 85 to 92%).

Selection criteria for solid fuel boilers

The main criteria in this case are the following:

1. Area of ​​a specific building... This parameter largely determines which boiler of what power should be purchased, and also affects the choice of fuel for it.
2. Floor slab height in living quarters.
3. Heat loss rate... This parameter is influenced, first of all, by the thickness of the walls and ceilings in the building, as well as the material from which the house is made. It will also be useful to take into account the area of ​​the openings of doors and windows.
4. Climatic features of a particular region... As a rule, the main emphasis is on temperature indicators during the cold season, since it is these data that make it possible to calculate the optimal heating power of the boiler.

To do this, you should take into account, first of all, the footage of the house. For example, to provide full heating for a 100 m² room, you will need to use equipment with a capacity of 10 kW. In this case, you should always remember about a certain power reserve, which should be approximately 1 - 2 kW.

Difference between manual and automatic boiler loading

The design of boilers with automatic fuel supply is based on the main part and a special bunker, directly into which the fuel is placed. In the event that it is coal, then the size of its particles should not exceed 25 mm. However, there is also the possibility of using pellets, which definitely do not exceed this parameter.

For continuous and high-quality operation, one fuel load is enough for about three to five days, which makes working with the boiler very convenient and easy.

At the same time, the size of the boiler bunker can be very different, it all depends solely on the preferences of the owners, since you can load a lot of consumables into this chamber, thereby forgetting for a long time about the need to replenish the coolant supply in the boiler.

Fuel is supplied through one of two options - either using a screw or using a piston. Regardless of this, it is safe to say that the most economical solid fuel boiler will definitely have automatic movement fuel supply, which will not only prevent excessive material consumption, but also can guarantee the stable power of the equipment.

These devices do not differ in economic efficiency, in addition, it is not recommended to mount them in residential premises, since their dimensions are very voluminous, which will be extremely inconvenient. It would be much more correct to install such equipment at an industrial-type enterprise, since it is far from always possible in a standard building to provide separate room for installing a solid fuel boiler.

What does the boiler heat exchanger consist of?

It is on these devices that you should dwell in more detail:

1. Cast iron units are distinguished by high performance if they run on coal fuel, since the use of firewood can negatively affect the capacity of the equipment.
   
   The main advantages of products made of cast iron are their affordable price, the versatility of the fuel used for operation, as well as the ability to quickly and easily repair the entire system for the entire system. However, this technique also has disadvantages, the main of which are a small efficiency ratio (about 65 - 75%), the need for regular, as well as high inertia rates.
2. In steel mechanisms, the main fuel is wood or briquettes created by processing wood waste (read also: "").

• the thickness of the metal used in the construction;
• method for arranging a heat exchanger;
• productivity factor;
• maximum operating time on one fuel load.

Technical characteristics of solid fuel boilers

The main technical parameters of such boilers are as follows:

• type of fuel used for work, which, as mentioned above, can be coal, firewood, peat briquettes, as well as recycled waste. Thanks to such a wide range of consumables, it becomes possible to significantly reduce the energy consumption required for heating;
• combustion chamber capacity which mainly affects the performance of the device and the number of fuel loads;
• work automation... Many mechanisms are equipped with a similar function, which helps to relieve yourself of constant control over the operation of the boiler system;
• product safety indicators... When choosing one or another unit, it is imperative to take into account how safe its use will be. So, the main elements that any boiler should be equipped with are the automatic shutdown function, as well as the presence of an alarm;
• energy consumption parameters... Some models are required to provide access to the mains, otherwise they will not be able to function. However, most solid fuel boilers are self-contained;
• product price... When choosing such a technique, you should not focus only on low cost, since the technical characteristics of cheap equipment are usually far from ideal.
