Solid fuel boilers of long burning from the manufacturer

On our site you can find out what is solid fuel boilers where you can buy them, how to choose high-quality appliances, find out what the price of such boilers is. These are steel or cast iron heating appliances that run on solid fuels. If a we are talking about a household unit, manual fuel supply is assumed, industrial designs are equipped with automatic supply and ash cleaning. Such boilers are installed where there is no gas heating, or as a backup means of heating.

Types of equipment

According to the type of control, boilers are divided into automatic and mechanical. Moreover, the second option compares favorably in terms of price and reliability. As a rule, such devices can be bought inexpensively. Boilers for heating need regular maintenance, such as descaling and cleaning, as this will help to avoid disruption of heat transfer from the boiler wall and damage to metal parts due to overheating. Modern solid fuel boilers are high-tech and safe, and their operation is stable. For advice on the choice of such equipment, you can contact our experts. The fuel for such devices as a long-burning solid fuel boiler is:

• . coal;
• . firewood;
• . peat;
• . pellets;
• . reed or straw.

Different types of fuel differ in burning time, which ranges from two to eight hours. Through the fuel exchanger, the heat released during combustion is transferred to water - the heat carrier of the heating system. As for long-burning boilers, such systems differ from conventional ones in their design. Here the combustion process does not start from below, but from above. The fuel ignited in this way burns much longer. The air distributor of such boilers has a telescopic design and constantly presses on the flame source under the action of own strength gravity. And thanks to this pressure, the fuel burns out gradually in horizontal layers. It is this design that makes combustion better and longer, which is very beneficial for heating. Additionally, such units have a longer service life, because the steel heat exchanger does not experience significant loads. Improvements in heating boilers, which have become more and more popular in recent years, due to the popularization of such systems, cause excessive pressure in the system and an increase in temperature. For this reason, they are dangerous, as they lead to ruptures in the heat exchanger tubes. To avoid such consequences, an expander tank is installed. It gathers excess water which expands when heated too much.

How to buy a unit

Boiler solid fuel long burning with a water circuit

The advantages of having a water circuit in a long-burning heating system include, first of all, performance, decent efficiency, quick heating of the coolant, rational heat distribution, and economy. But remember that if we choose a cast iron apparatus, its maintenance will still be quite complicated. A solid fuel boiler with a water circuit is quite inexpensive compared to other units. The requirements for documents for the installation of such heating systems are also low. To install a solid fuel boiler with a water circuit for your home, you will only need proper ventilation and a chimney in the room where this equipment will be installed.

Installation of a solid fuel boiler

Installation of heating boilers plays no less important role for the safety and reliability of the system than the devices themselves. Therefore, only real experienced professionals should be engaged in such work. Solid fuel heating boilers, as a rule, do not have controls and a circulation pump in their equipment. They also lack a security group. The boiler piping scheme is chosen in such a way as to solve these problems. To do this, the scheme includes additional equipment, devices and nodes. For example, a heat accumulator and a boiler indirect heating. These additions are needed to ensure uninterrupted and high-quality operation of the heating system. Here is how a solid fuel boiler is usually installed:

1. 1. First of all, before installation, the power of the solid fuel boiler is determined.
2. 2. A separate room is allocated for him, where all safety rules will be observed. The floors of this place are concreted.
3. 3. The installation of the apparatus itself and other components, such as regulators, chimney and other system components.
4. 4. Setting the heating boiler.
5. 5. Regular work on the control and cleaning of equipment.

Double-circuit boilers are usually installed in small buildings, for example, in wooden house where there is one bath near the kitchen. Then the boiler can be located not only in a separate place, but also in the kitchen.

Solid fuel boiler piping

The piping is a set of equipment included in the heating system. The binding must include:

• . heating boiler;
• . pipeline;
• . warm floor, batteries;
• . fittings;
• . control equipment;
• . control equipment.

Tying a solid fuel boiler is the work of a real installation master, because everything depends on him future work systems. On our website, you can easily find such specialists in Moscow who take a responsible approach to the creation of heating systems. Here are the basic rules that must be observed in such a matter as piping a heating boiler:

1. 1. It is desirable to have control devices.
2. 2. The difference in temperatures of liquids during circulation should not exceed twenty degrees.
3. 3. The pressure must be within the range of the relevant regulations.

The options for piping schemes are divided into schemes with natural circulation (open and closed), a collector connection scheme, with forced circulation, a hydraulic arrow, a heat accumulator and an indirect water heater.

Wiring diagram

The connection of heating boilers, as well as their further work, depends on how professionally the wiring of pipes and heating radiators is performed. Only a person who knows the principles of its operation and has rich experience in such procedures can create an ideal scheme for connecting a heating system.

Modern solid fuel boilers are used for heating private and country houses.

Despite the sufficient level of development of gasification in our country, heating in many regions is due to solid fuel heating boilers, which remains relevant. Wood-fired boilers are in demand.

This choice of heating systems is due not only to the greater availability of this type of fuel, but also to the high efficiency of the latest models of solid fuel heating boilers for long-term combustion, both domestic and foreign, made according to modern technologies and from quality materials.

At the same time, prices for solid fuel boilers in Moscow and the regions practically do not differ, and today it is not a problem to choose and buy a solid fuel heating boiler.

A solid fuel heating boiler is a complex engineering device that heats a circulating coolant by burning wood and other wood or coal fuels and their derivatives: briquettes or granules (pellets).

Today, buying long-burning solid fuel boilers is a real opportunity to get high-quality heat supply and ensure a continuous supply of hot water in a private cottage or country house, with minimal financial and operational costs.

Varieties of solid fuel heating boilers

By technological scheme fuel combustion solid fuel heating boilers can be divided into systems using classical combustion, and pyrolysis on solid fuel. Compared to the classical combustion method (classic solid fuel boiler on wood and coal), pyrolysis uses unique ability solid fuel turn into a gaseous state at high temperature and the absence of air.

Such gas burns with much greater efficiency, providing pyrolysis solid fuel boilers with long burning, high efficiency and a long period of operation between fuel fillings. Of course, they have a slightly higher price than their classic counterparts with the same power, but the economy and ease of maintenance justify the cost at the very least. a short time after purchasing them.

Traditional solid fuel boilers for long burning may have design differences in the approach to designing the combustion chamber, as well as in the use different material for the manufacture of a heat exchanger - cast iron or steel. A solid fuel boiler using a first type heat exchanger has a significantly greater weight and brittleness with an increase in thermal performance, while steel structure is durable and resistant to damage.

The operation of solid fuel boilers in automatic mode allows not only to reduce operating costs by shifting most of the maintenance and control of equipment operation to automation, but also using a solid fuel boiler with automatic loading to achieve the level of comfort obtained from the use of gas boilers.

It is not yet easy to buy such solid fuel boilers on the Russian market, but given the promising opportunities, we can assume a great future for them.

• Boilers (especially those using coal as fuel) are almost universal in the choice of fuel: firewood, waste, household waste, briquettes, pellets, sawdust and much more
• Carbon monoxide produced during the combustion process does not enter the chimney, but serves as a raw material for the production of combustible gas
• Long burning time (from 6-8 hours)
• Ability to easily control the intensity of combustion due to air supply

They also have specific disadvantages:

• Coal needs a separate storage place (without dampness and strong wind)
• Periodic cleaning of the combustion chamber and smoke exhaust system from accumulating soot is required.

Tips for home heating with solid fuel boilers

Remember that no matter what kind heating boilers you have not chosen, you should optimize the condition of the room itself. The walls must be insulated from the outside and from the inside, and in window and doorways draft must be removed. You should also take care of the condition of the attic and basement. The temperature must be such that winter time it was slightly higher than the outer one. If it's warm there, then the heat goes out through them to the street, and you needlessly heat the air and the earth around the house.

The following brands are especially popular:

• Buderus is a product of a world famous company that combines German quality and the most advanced developments in automation systems using traditional components such as a cast iron or steel heat exchanger;
• Protherm - the choice of equipment of this brand allows you to achieve excellent fuel combustion efficiency, achieved by increasing the combustion chamber and applying cast iron heat exchanger in combination with horizontal exhaust of combustion products;
• Biomaster is one of the most environmentally friendly boilers using wood and pellets as fuel;
• FBRZH - Russian manufacturers provide stable quality, reliability and decent technical characteristics of their products at the lowest prices. At the same time, the design of the FBRZh boilers allows loading fuel only twice a day.

Types of household solid fuel boilers

Units can use various types of energy resources:

• firewood;
• granules;
• coal;
• peat.

There is also a universal option - a solid fuel stove, which can work effectively with any of the options listed.

The classification is also carried out according to the method of combustion. Boilers can be:

• classic;
• pyrolysis;
• prolonged burning.

Traditional devices are often used for firewood and peat. Their operation is simple, however, during operation, the equipment needs regular replenishment of the furnace - at least four times in twenty-four hours.

Pyrolysis models use the process of gas evolution during fuel smoldering. Thanks to this, the efficiency of the units tends to incredibly high rates. It is pyrolysis equipment that is the most economical option for home heating. However, he also has a minus - whimsicalness in operational conditions. For example, such a coal-fired boiler can only use dried rock, the moisture content of which does not exceed 20%.

Long-burning devices do not need frequent bookmarking: they can work with one serving for a whole day! This is best option for a private house of a large area. Most often, these units use firewood or briquettes.

Features of solid fuel heating boilers

A pyrolysis-type solid fuel coal-fired boiler has a complex design and a significantly high price; long-burning models are also not entirely simple. But traditional devices are popular home solutions that can be found everywhere.

The units are made of durable heat-resistant materials - cast iron and steel. Iron-carbon devices rarely require cleaning, are characterized by high inertness, and excellent resistance to corrosion. Steel devices warm up much faster, but they cannot boast of such a long working period. At the same time, they are cheaper and lighter than cast-iron "colleagues".

Solid fuel models can be volatile or autonomous. It is worth noting that boilers with automation always require a source of electrical energy, but they provide full automation of work.

Some ovens may be supplied hobs, That is great option for a small country house.
