Solid fuel pyrolysis boilers long burning.
The basic operating principle of the boiler is the separation of flammable pyrolysis gas from solid fuel and the subsequent combustion of the remaining solid fuel (coke) and pyrolysis gas separately.
When solid fuel burns with a lack of oxygen, flammable pyrolysis (furnace) gas is released abundantly, which in turn burns out in the second afterburning chamber. As a result of this process of orderly combustion of fuel, maximum high efficiency boiler up to 92%. The fuel releases almost everything that can burn and release heat. Only exhaust gas exits into the chimney, which consists of almost nothing but CO2, N2, O2 and is no longer capable of producing any energy. As a result, Bourgeois-K boilers are considered environmentally friendly, even when burning aggressive fuel. All emissions comply with MPC (Maximum Permissible Concentration).
Thus, using boilers pyrolysis boilers Burzhuy-K You get:
- . fuel savings up to 5 times compared to direct combustion boilers.

Design and principle of operation of pyrolysis boilers "Bourgeois-K".
Pyrolysis boilers "Bourgeois-K" are made from steel of various thicknesses by welding parts and assemblies. The boiler structure is shown in Figure 1.
|
Water enters the pyrolysis boiler through the return line pipe (8), is heated by passing through the water jacket of the boiler (12, 13, 14) and in heated form leaves the boiler through the supply line pipe (5) into the heating system. Firewood or other fuel is placed in the combustion chamber (19), where it is burned, when limited access oxygen. The amount of oxygen in the combustion chamber is regulated by the primary air supply control door (3); more details about the door operating mode can be found in the “Firehouse Rules” section. On models with automatic temperature control, the door is controlled by a sensor. The pyrolysis gas released during the fuel gasification process naturally enters the exhaust gas afterburning chamber (17), where it is mixed with secondary, preheated air (11) through afterburner injectors with calibrated holes. As a result of a thermochemical reaction, the process of ignition of unburned fuel gases occurs, which makes it possible to turn into thermal energy 90% of small particles contained in smoke, thereby preventing their release into the atmosphere. Residual flue gases are discharged through the flue gas pipe (6) and the chimney.
- The complex design of the boiler and the combustion process based on the principle of pyrolysis allows us to achieve a significant increase in combustion time from one load of fuel, compared to conventional solid fuel boilers.
- The average burning time from one bookmark is 8-10 hours.
- This allows you to significantly save fuel and increases the time between fillings, which is a distinctive quality of the Burzhuy-K pyrolysis boilers.
- There are pyrolysis boilers with a lower location of the pyrolysis chamber; in this case, the pyrolysis gas released during the combustion process is forced into it using a fan (supercharging) powered by an electrical network.
- Pyrolysis boilers "Bourgeois-K" are non-volatile and do not require electricity!
Solid fuel heating pyrolysis boilers "BURZHUI-K" are manufactured in strict accordance with the norms and provisions of the law. The complex welded steel structure of the product consists of more than 200 parts! All boiler components are made of heat-resistant and corrosion-resistant boiler steel. Only steel grades are used that are included in the list of materials used for the manufacture of pressure vessels (Resolution of the Gosgortekhnadzor of Russia No. 20 dated April 18, 1995, PB 10-115-96, “RULES FOR THE CONSTRUCTION AND SAFE OPERATION OF PRESSURE VESSELS” ). They contain a conclusion from OJSC NPO TsNIITMASH (Central Research Institute of Mechanical Engineering and Metalworking) on the possibility of using steel welded solid fuel boilers in the production. The basis for issuance is the conclusion of the TsNIIK (Central Scientific Research Institute of Corrosion), certification for resistance to MCC and the conclusion of the testing center "TsNIITMASH-Analytics-Strength" for heat resistance.

Many owners of private houses are increasingly choosing a pyrolysis boiler as a heating source. However, imported devices have a significantly high cost. Not so long ago appeared on the domestic market solid fuel boilers pyrolysis type Russian production under the brand name Burzhuy K. During this time they have earned many flattering reviews from both consumers and professionals. In this article we will look at model range Bourgeois K boilers and let’s see what their main advantages are. So let's get started.
What is a pyrolysis boiler?
Pyrolysis is a method of dry distillation of solid fuel. Under the influence of high temperature, it decomposes into solid and gaseous components, which are then burned separately.

- Maximum operating temperature 90C;
- Output gas temperature up to 150C;
- The minimum permissible pipe height is from 7 to 13 m;
- Chimney diameter from 150 to 250mm.
Pros and cons
Bourgeois K heating boilers have a number of advantages, thanks to which they have taken a leading place in sales among devices domestic production. Let's take a closer look at their advantages:
![](https://i1.wp.com/kotlydlyadoma.ru/wp-content/uploads/kotel-na-tverdom-toplive-burzhuj-k.jpg)
thermal insulation
All modifications of Burzhuy-K boilers are equipped with reliable thermal insulation from mineral wool. This will allow you to significantly reduce heat loss and reduce home heating costs.
steel body
The body, as well as all other components, are made of special heat-resistant and corrosion-resistant steel, developed specifically for the production of boilers and capable of operating under pressure. The device contains more than 200 different parts.
powder coating
Powder coating provides protection to the case solid fuel boiler from moisture and various salts and acids. This coating is not afraid high temperatures and has high performance abrasion resistance and strength, which will allow you to maintain a decent quality for a long time appearance boiler
automatic combustion control
Thanks to the presence of a mechanical temperature regulator, the likelihood of overheating is significantly reduced. Compliance with the required temperature conditions will extend the service life of both the pyrolysis boiler itself and the entire heating system as a whole.
energy independence
The absence of components in the design that require power supply provides undeniable advantages for use in areas remote from power lines.
presence of a FGP circuit
In addition to performing its main function - space heating, the double-circuit pyrolysis boiler Burzhuy K is capable of producing hot water for sanitary needs.
efficiency
By using the principle of pyrolysis, high fuel efficiency is achieved. When the boiler is operating, a small amount of ash remains, and the gaseous waste consists almost entirely of water vapor.
A pyrolysis boiler is a real godsend for those who live in private houses and dachas where there are frequent interruptions in the supply of gas and electricity. This unit is completely autonomous and does not require connection to either electrical or gas distribution networks. The device has already earned wide popularity and recognition due to the fact that it is optimally suited for working in the Russian climate.
The modern stove "Burzhuy-K" is essentially similar to the famous potbelly stoves of the beginning of the last century. Any fuel can be used as fuel for the furnace. solid fuel- firewood, coal, pellets and briquettes, depending on which fuel is more accessible and cheaper in your case.
But the operating principle of this device is fundamentally different from other solid fuel boilers. During the operation of the boiler, combustion products saturated with carbon monoxide, since the design provides for a system for their afterburning.
By design, the device is a one-piece unit consisting of a two-chamber firebox and a water circuit. Built-in temperature sensor allows precise installation temperature regime with an error of up to 3 degrees. One load of fuel is designed for 15 hours of operation of the device.

Pyrolysis (gas generator) boilers are a good option for heating if you have cheap solid fuel at your disposal or other energy sources are simply not available. The equipment runs on wood, coal, peat briquettes, but unlike conventional CTs it has more high efficiency– up to 92%. Exactly like this efficient systems Produced by TeploGarant.
The pyrolysis boiler Burzhuy-K has high performance due to double use of fuel energy. In addition to the main combustion process, its design also allows the release of released gases, which are usually simply removed from the firebox through the chimney. They are burned in an additional chamber with a separate air supply. But the long-burning boiler “processes” the primary fuel under conditions of lack of oxygen. This makes firewood smolder slower, and gas generation is more efficient. Boiler productivity increases, as do the time intervals between fuel fills (up to 8 hours), and heating costs are reduced.
Many owners note in their reviews that a pyrolysis boiler produces a small amount of ash after burning wood and briquettes. That is, the maintenance of the equipment is simplified if its operation is configured correctly. But if the technology is violated, problems arise: a layer of tar and soot appears on the inner walls of the models, which is very difficult to remove. Why is this happening?
Installation Requirements
Judging by the reviews of owners and specialists, any pyrolysis boiler Burzhuy-K is demanding in terms of performance and correct connection chimney. It should be:
- made of stainless steel;
- insulated and sealed;
- made without horizontal sections and with a minimum of turns;
- be of sufficient length to rise above the roof by at least half a meter.
If all these requirements are not met, the boiler will quickly become overgrown with soot from the inside, or even simply will not be able to enter gas generation mode. That is pyrolysis combustion you won’t get it, but Burzhuy-K will work like a regular solid propellant. As a rule, it is failure to comply with installation requirements that leads to inefficiency in the heating system, excessive fuel consumption and other problems. Negative reviews appear, and owners think about buying other equipment.
Model range
Having figured out how a pyrolysis boiler works, let’s move on to a review of Burzhuy-K devices. The entire range of equipment domestic manufacturer According to purpose, they can be divided into two groups:
- Water heaters use their own double shell casing as a heat exchanger. Some models can be connected to an additional DHW circuit.
- A pyrolysis air-heating boiler does not have a water jacket, and therefore physically cannot produce power exceeding 150 kW.
In turn, TeploGarant produces a line of domestic (up to 100 kW), industrial (up to 800 kW) and universal mobile boilers. They all differ from each other not only in performance, but also in the installation method. Characteristics of the most popular models from these series we will consider.
1. Burzhuy-K Standard.
A family of compact and inexpensive floor standing boilers for household use. Since they are considered budget, the equipment does not have a mechanical draft regulator that controls the opening of the damper. But the duration and efficiency of burning each load of fuel will depend on it. There is also no thermomanometer, but TeploGarant offers to buy the missing elements of the system separately.
Standard series boilers with a power from 10 to 30 kW are in great demand as they are capable of heating private house area 100-300 m2. All-welded steel structure has additional covering with heat-resistant spraying and non-flammable basalt thermal insulation. This equipment is non-volatile, since, unlike foreign analogues, it operates without forced pressurization.
With regard to functioning in heating circuit, then here the Burzhuy-K pyrolysis boiler heats the liquid in the system due to water jackets around the combustion chambers. So the unit body itself is a very effective heat exchanger. The supply pipe is located at the top, the heated water outlet is at the bottom.
2. Bourgeois-K Modern.
This series is more expensive and is represented by models that produce power in the range of 12-32 kW. Unlike the Standard, there is already the possibility of connecting to an additional heat exchanger of the DHW circuit. Just do not forget to review the power characteristics, because part of the generated energy will be spent on water supply. The efficiency of Burzhuy-K Modern reaches 82-92%, and the design is supplemented with a draft regulator. This simplifies operation management, since simple automation is able to control the air flow in the combustion chambers.
High performance products
Industrial heating boilers Burzhuy-K, presented in this series, produce a power of at least 50 kW. The maximum that these units are capable of is 800 kW (enough to heat an area of 8000 m2). We will not give a description of the principle of their operation, since these models completely replicate the Modern household lines. The only difference is in the size of the firebox and, accordingly, in the price.
2. Air heating TV.
The characteristics of the TV line systems are more modest: their operating range is 12-150 kW. However, any long-burning boiler is capable of heating air up to +60-300 °C, and requires fuel loading much less often than water models. TV units are in little demand because they do not use the most efficient coolant. The cost of the equipment is also quite high, but they are ideal for heating production facilities.
It's already automated systems, operating from the network, since the pyrolysis boiler provides forced air injection. But experts in their reviews recommend using simplified versions of the chimney with TV, since the pipes in these models constantly need to remove soot and condensation.
3. External Tn.
Modular TeploGarant series Burzhuy-K Tn are mobile equipment for use, so to speak, where required. Although the weight of the units is considerable: the lightest T-12AMK pulls 400 kg, and the mass of a 100-kilowatt unit reaches 2 tons.
If somewhere outside the room there is a need for economical and long-lasting heating, it is better to purchase a modular device. Pyrolysis solid fuel stoves are used when it is not possible to create a mini-boiler room in the house. The Tn models cope with the work themselves, since the maximum configuration includes everything necessary:
- circulation pump;
- water filter;
- defrost protection - automatic coolant run if the pyrolysis boiler has not been turned on for a long time;
- shut-off valves;
- safety and mixing valves.
Like other series, Burzhuy-K Tn models are easily integrated into any heating system, regardless of the features of its management. Outdoor solid fuel boilers have an improved chimney design, ensuring a longer service life. The equipment comes with a collapsible frame. It gives an aesthetic appearance and protects against atmospheric exposure, and the walls and roof of the “booth” are covered with thermal insulation.
Reviews from people
“My first disappointment with the pyrolysis Standard is the flimsy grates. They literally burned out for me during the season. As I understand it, many people face a similar problem. Most likely, it was necessary to replace the grille with something more serious immediately after purchase, but I didn’t want to get into new technology. Otherwise, it’s a normal solid-fuel device, although the price of the Burzhuy-K model clearly does not correspond to the functionality.”
Valentin Basov, Nizhny Novgorod.
“I struggled for a long time with cleaning the boiler - almost everything was clogged with tar from the inside. And getting into Burzhuy-K is not an easy task (those who have tried will agree with my opinion). It’s good that I came across a review where smart man I advised to insulate the boiler room under the solid fuel unit. Oddly enough, the problem was solved. Probably due to the low temperature of the air entering the pyrolysis burners, soot was released.”
Nikolay, Moscow.
“The characteristics that the manufacturer claims are probably achievable on Bourgeois only when using ideal fuel (very dry, with good calorific value). But I don’t want to spend money on factory briquettes, and to be on the safe side, I decided to buy a long-burning boiler with a power reserve of 25%. Now the house is warm enough, but not hot, so I advise you to focus on this indicator. Buying a model, of course, will be much more expensive, but it’s better than freezing in winter.”
Dmitry, St. Petersburg.
“I’ve been using the 20-kilowatt Bourgeois-K Standard for two years, and the longer I go, the more I like it. Although I couldn’t get used to it the first winter: I had to clean it all the time. Now I’ve gotten used to it, I’ve adjusted the boiler’s operation, and there are no such problems. I’ll give you some advice: put in firewood that is not only dry, but also large enough, then you really won’t have to add it more often than every 8 hours.”
Oleg Ponomarev, Syktyvkar.

Dear company "BURZHUI-K"
Finally, we have put into operation your T-10 pyrolysis boiler. Ordinary country house(log house) is located in the Kostroma region in the village of Kalinka.
Since the construction of the house, the Russian stove has served us faithfully for heating, and it still stands today. Many of our friends have had them for a long time heating boilers on wood, but when talking with them, it was not clear why it was needed at all - the same amount of wood is burned per season, you need to buy pipes, radiators, and make sure that the heating system does not defrost.
I don’t remember from whom, but I heard that there are pyrolysis boilers that operate much more economically than conventional solid fuel boilers. Having estimated that an 8-10 kW boiler would be enough for our 80 meters, I began to “take a closer look” at what was offered in specialized stores. Almost immediately I came across boilers with unusual name"BURZHUI-K". And after the seller told me that imported pyrolysis boilers cost 2 times more (and your boiler is also too expensive for my budget), and that they also require electricity to operate, I thought what to look for next would just be a waste of time.
We haven't taken down the stove yet, but put the boiler in separate room at the entrance. It wasn’t much work to do the wiring, fortunately now we have polypropylene and don’t need to cook anything. I had to tinker with the chimney because I was told that it must be insulated and located vertically up from the boiler. I also installed a circulation pump, although I was not advised to do so. But it’s more convenient, the house warms up by 10 degrees in less than an hour!
We drowned this season regular boards, so-so firewood, I’ll tell you. But literally on the second or third day, having gotten used to the operation of the air damper, we reached 7 hours from one laying and this was on pine boards! In the summer next year We are planning to buy good birch firewood, I am sure that the boiler will work even longer than the specified 8 hours!
We are very pleased with the boiler, for which we thank you very much.
Sincerely, Oleg Vitalievich Zaemov.
