Long burning boiler types. What is a household wood boiler made of?

More and more city dwellers are striving to escape to permanent residence outside of megacities. Away from noise, dust and bustle. Now almost everyone can travel on business in their own car; distances are no longer an obstacle. The only thing that stops many is the level of comfort that it provides country house. First of all, this concerns heating. And if there is no gas nearby, then you have to look for alternative methods to solve the problem. One of such solutions may well be a solid fuel boiler with improved characteristics, which we will consider today.

What is a long-burning boiler

There is no science fiction or space innovation in the design of the device. Only competent development and subtle knowledge of physical processes made it possible to develop such a boiler. A wood-burning boiler that can burn for a very long time without requiring any special attention and having good efficiency. These are the main characteristics of the device. Besides, the firewood is quite accessible view fuels, they are much cheaper than gas, and the boiler volume can be selected to suit any room.

The operating principle is simple and clear - solid fuel it does not just burn in the firebox, as in a conventional stove, but slowly smolderes, constantly producing heat. The combustion process is artificially slowed down due to the fact that the access of oxygen to the combustion site can be regulated within fairly wide limits. The slower the fuel burns and the larger its volume, the more heat we get at the exit of the device.

Such a boiler is several times more economical than a conventional solid fuel boiler, and its operating period may generally be limited to heating season. In October you can light it, and at the end of April you can extinguish it, while refilling the fuel every 5-7 days. Such devices are produced both for domestic use and for heating industrial facilities, the only difference is in size. An industrial solid fuel boiler that burns for a long time, the price of which is tens of times higher than a household one, can take separate room and heat entire workshops.

Device classification

Firewood, sawdust, coal and peat are the main types of fuel for these devices, and according to the method of heat generation, the boiler is designed in only two types:

A pyrolysis boiler consumes only dry fuel, while it can show high efficiency and profitability. Low fuel consumption is due to the fact that it burns out in the combustion chamber almost completely, thereby reducing heating costs and reducing the time for care and maintenance of the combustion process.

Characteristics of pyrolysis boilers

All pyrolysis boilers, which are produced by industry, are similar to each other in terms of indicators, so we can talk about the average values ​​of such equipment, which differ slightly from each other, depending on the model. So, almost every long-burning boiler has operating pressure about 1 atm, the outlet coolant temperature can be from 70 to 90˚C, while the efficiency of such devices is 85-90%. For domestic boilers, the average power is at least 80 kW, and the temperature of the exhaust gases can reach 250˚C and higher.

Pyrolysis boilers can have a lot of positive advantages over other types of heating equipment, in particular, they note:

• excellent heat dissipation;
• high productivity;
• safety, possibility of installation directly in a residential building;
• a variety of design finds in the design of device cases;
• temperature adjustment is simple and without the use of additional expensive devices;
• easy setup of all parameters;
• the ability to install automation equipment, alarms and automatic adjustments;
• low fuel prices compared to electricity and gas, and it is the only option when supplies of gas or electricity are limited or non-existent.

Operating principle and drawings of a long-burning solid fuel boiler

Heaters can operate according to several schemes, which is reflected in their design. Boilers that are based on the principle of upper combustion are somewhat simpler than boilers with a lower combustion chamber, however, their operating efficiency is almost the same. Upper hearth boilers first went into mass production only in 2000, and since then their design has been used by many to make boilers with their own hands.

The combustion chamber of such a boiler can be quite voluminous, up to 500 cubic decimeters. Therefore, the larger the combustion chamber, the longer the boiler can operate without filling, up to several days. Fuel burns from top to bottom, and the mine oxygen supply limiter automatically reduces the combustion chamber as fuel is consumed. The heat generated during smoldering is transferred to a heat exchanger.

Prices for long-burning boilers

Long-burning boilers are produced by both domestic enterprises and many foreign companies. The most popular are Lithuanian long-burning boilers Stropuva. The company produces a wide range of models, varying both in power and in the area of ​​the heated room.

Depending on your budget, you can buy a 10 kW long-burning boiler with a heated area of ​​up to 100 square meters. Such a boiler will cost 90 thousand. It can operate on firewood and wood waste.

In conclusion, the video: how to choose a solid fuel boiler for a private home?

The main disadvantage of solid fuel heating boilers is the short operating time from one fill. The fuel in the firebox burns out within 2-3 hours. Long-burning wood-burning boilers have a special design that increases the battery life to several days.

The principle of operation of a wood heating boiler, long burning

The design and principle of operation of a wood-burning boiler for long-term operation from one load is aimed at recreating similar conditions in the limited space of the combustion chamber. Firewood does not burn in the full sense of the word, but smolders. The operating time increases, and the lack of heat is compensated by the afterburning of the released gases.

The design of long-burning boilers includes the following components:

Most long-burning boilers are equipped with an enlarged loading chamber. Internal organization allows for autonomous operation for 8-12 hours. Some manufacturers offer boilers that can operate for several days on one fill.

How to choose a slow burning wood boiler

1. Performance.
2. Design features.
3. Manufacturer country.

Power calculation

1. Calculate total area Houses.
2. Making a calculation required power boiler using the formula 1 kW = 10 m².
3. If the design has a DHW circuit, add 15-20% of the reserve to the result obtained.

Design features

Separately, it is worth highlighting boilers that have a built-in storage boiler. Models of this type have one heating circuit, but are designed to heat the coolant and hot water.

The best manufacturers

Thanks to consumer reviews, the following rating of long-burning wood-burning boilers was compiled:

• German boilers - equipment are offered by several companies, among which models and stand out. The product is fully automated and has economical fuel consumption.
• Austrian boilers are produced models that are almost identical in quality to German units. Distinctive feature Austrian boilers are characterized by maximum automation and the presence of a multi-level security system. Products are offered by concerns, Wirbel and others.
• Czech boilers - the most popular brands are ATMOS. Universal stations operating on both wood and other types of fuel remain in demand. Judging by the number of sales, boilers with cast iron heat exchangers are in particular demand among domestic consumers.
• Baltic boilers - Russian consumers were able to evaluate the quality and thermal efficiency of Latvian boilers, the main advantage of which is a long operating time from one load of fuel. In offline mode, the boiler can operate for more than 2 days. The design of the unit is so simple that local “craftsmen” offer diagrams of the device for self-assembly.
• Russian boilers, the first models of long-burning boilers, were not entirely successful and had many design flaws. In modern models, the errors have been corrected, which has increased the popularity of heating equipment. At the moment, products are offered by factories Teplodar, Trayan and others. Low price for long-burning wood heating boilers, unpretentiousness to fuel quality - all this explains the high popularity of products from domestic manufacturers.
• Polish boilers - products from manufacturers are represented on the market: , Defro, Wichlacz. The boilers are practically analogues of German and Austrian companies, but at a more reasonable cost. The popularity of the models is somewhat limited by difficulties with the supply of components and the recently increased price of the units.

How to make wood burn for a long time

You can achieve long burning of firewood by carefully following the manufacturer’s recommendations:

• Firewood is lit with the damper fully open.
• The boiler is switched to long-burning mode only after reaching a temperature of 600°C.
• The moisture content of firewood should not exceed 20%. drown coniferous species wood is not recommended.

• The minimum temperature of the coolant at the outlet should not fall below 65°C.
• It is correct to heat a boiler with hard wood: aspen, beech, acacia, oak, etc.
• High humidity of firewood leads to abundant release of resin.

How to load firewood correctly

• The logs are split into large pieces.
• The firewood is placed in the firebox as tightly as possible. It is important to avoid voids between logs.
• The length of the logs should be smaller sizes loading chamber, at least 5 cm.

Ignition is carried out exclusively with dry splinters. It is prohibited to use gasoline or kerosene to light firewood. From time to time, it is recommended to use special chemical briquettes that remove tar deposits on the walls.

How much firewood do you need for the winter season?

• It is generally accepted that to heat every 100 m², 3 Gcal/month is required.
• When burning a kilogram of wood, 3200 kcal is released.
• To obtain 1 Gcal, long-burning boilers burn 312 kg of wood.
• To obtain 3 Gcal, approximately a ton of wood will be required.

During the heating season, to heat a house of 100 m², you need 7-8 tons of firewood.

Rules and regulations for installing a long-burning wood-burning boiler

Which is better - a long-burning boiler using coal or wood?

This question is always asked by those who are just thinking of switching to long-burning non-solid fuel boilers. Let's look at the positive and negative aspects of each type of fuel.

In general, these are all the main criteria by which one or another type of fuel is chosen.

VIDEO: What is the difference between a long-burning boiler and a regular boiler?

Solid fuel boilers are indispensable in conditions where there is no centralized gas pipeline. Solid fuel boilers are convenient to use in country houses or cottages. The main positive quality of solid fuel heating boilers is complete independence, because you don't need gas or diesel, the boiler runs on wood, coal or pallets. So that you better understand what solid fuel boilers are, let's look at them in more detail.

What is a household wood boiler made of?

Solid fuel boilers come in two types: steel and cast iron. It's difficult to say which material is better, because... they both have a variety of positive and negative qualities. Boilers made of steel weigh little and have low cost. Such solid fuel boilers are more resistant to temperature changes, but, compared to cast iron counterparts, their service life is noticeably shorter.

In turn, cast iron solid fuel boilers are very strong and durable, but they have one significant drawback - weight, they are very heavy. In addition, cast iron is a fragile material; if the temperature difference exceeds 20 degrees, this may lead to the destruction of the boiler heat exchanger section. Such nuances must be taken into account when designing a heating system with a boiler.

Heating your home at a profit

Boilers are classified as volatile and non-volatile. Everything is simple here: energy-dependent people need a constant connection to electricity; they are equipped with an electronic control panel, various sensors and units. Solid fuel boilers are convenient to use, but in the event of a power outage, the installation also stops working. Non-volatile solid fuel boilers are a completely analog system that does not require connection to the electrical network. For these purposes, a special heating system with slopes and large diameter pipes.

Pellet boiler, as an option for a summer residence

On our own pellet boilers very economical, but even among them there are models that take the concept of saving fuel resources to absolute new level. Next we will talk about long-burning solid fuel boilers or, as they are also called, pyrolysis boilers. Such water boilers operate according to unique technology, which was developed relatively recently. The principle of its operation is the dry distillation of fuel. Under the influence of high temperature, at insufficient quantities oxygen, pyrolysis gas begins to be released from the wood.

The moment the pyrolysis gas passes through the ceramic nozzle of the boiler, it begins to mix with oxygen and burns in the combustion chamber at very high temperatures. high temperature(more than 1100 degrees Celsius). This complex technology makes it possible to extend the fuel combustion cycle by approximately three times! In addition, in such boilers less ash and soot are formed, they are less inertial. The disadvantages of long-burning boilers include the fact that for high-quality work they need completely dried firewood. They are also volatile.

When it comes to solid fuel boilers, pellet models cannot be ignored. As you know, a significant disadvantage of all solid fuel devices is that coal (if the boiler is coal) or wood (if the boiler is wood) often differ in their composition and quality, so when using them it is quite difficult to achieve a constant combustion temperature. You can forget about this problem once and for all by using a solid fuel boiler with briquettes.

What he really is?

The principle of its operation is similar to other solid fuel devices, key difference consists of using briquettes as solid fuel. Pellets are biofuel produced from peat and wood waste. They look like small cylindrical granules that come in bags. The pellet type heating device is practical and easy to use, because... Fuel is supplied automatically, and some models even remove ash and soot themselves. A pellet boiler allows you to accurately calculate the amount of fuel consumed, as well as obtain consistently high efficiency.
