Pellet boilers pyrolysis master. Review of pellet boilers "Pyrolysis Master" of the updated series. Fire safety of a pellet boiler

Today, a large number of brands are represented on the Russian market, offering pellet boilers of various modifications and functionality.

By design, all the wealth of choice can be combined into just a few groups. To make it easier for you to make a choice, we recommend that you pay attention to just a few parameters that will give a complete understanding of whether the game is worth the candle in one or another sample under consideration.

1) Efficiency of the pellet boiler heat exchanger:

Efficiency index - directly affects your annual costs for the purchase of pellet fuel - the higher this indicator, the lower your costs.

Usually it ranges from 80 to 90%, however, there are models in which the efficiency reaches 92% due to a well-thought-out heat exchanger.

Some manufacturers offer for an additional 10-12 thousand rubles to increase the efficiency from 85 to 90-92% to purchase turbulators for their boilers, which is not the best option due to the fact that these steel elements are not durable and you will have to periodically buy new ones for those or 10 thousand.

It is better to immediately select a boiler in which a developed heat exchanger guarantees maximum efficiency without additional wear parts.

Remember, after buying a pellet boiler, your heating costs are just beginning - choose the most highly efficient models with maximum efficiency. They can be found for the same money as the most popular models with less efficiency.

2) Type of pellet boiler burner:

There are two types of burners - flare and retort. Each type has several varieties.

Let's talk briefly about flare burners: either expensive, or not of high quality and not durable. Both options do not increase the rationality of the choice. Therefore, we recommend narrowing the selection of the boiler to designs with retort burners.

Retorts are of vertical and horizontal type. In both types, there are not whimsical solutions, but this factor should be taken into account. Unpretentiousness means the ability of the burner to work on pellets of any quality without failures. There are many solutions from different manufacturers - almost all of those presented in our catalog cope with this problem.

In our opinion, horizontal tray-type retorts are more practical - in them, the risks of clogging with combustion products and emergency shutdown of the boiler are minimized.

3) Fire safety of pellet boiler:

This problem is solved in different ways, we advise you to select boilers in which the supply of pellets is organized using two screws with an air break in the transport channel - according to statistics, boilers with such an architecture of the device supplying pellets to the burner are the most fireproof.

If you are offered a boiler for 10-20 thousand rubles cheaper, but with a single screw feeder - think about the future ...

The described signs of a quality boiler are not exhaustive, but they will help reduce the risks of making the wrong choice to almost zero, so we recommend that you take this information into service before going to the store.

Prices for boilers of the Standart series

Prices for boilers of the Premium series

Pyrolysis Master TM is ready to offer a series of long burning boilers based on gas generating technology. Equipment modifications make it possible to work on heating both industrial facilities and private individual houses. Such systems are especially effective in the woodworking industry, since they allow the use of production waste as an energy carrier.

Principle of operation and design features

Due to their design, gas-fired boilers are a fairly cheap source of heat energy conversion. The main advantage here is a multi-chamber system that allows gas generation from solid fuels. The resulting gas, passing through the stage of efficient combustion, transfers the maximum amount of heat through the heat exchanger.

Distribution of chambers of the gas generating boiler

The heating equipment of this brand is equipped with four chambers, each of which performs its specific function: The main chamber for loading and low-temperature impact on the fuel volume. Here, solid fuel is separated into combustion gases and non-combustible residue (ash);

The ash pan or ash chamber, being under loading, has the function of collecting ash; High temperature combustion chamber. This is where the combustion takes place. Thanks to the special design of the air nozzles, the process becomes complete and environmentally friendly. The walls of the chamber are protected with fireclay bricks, which increases the working life of the boiler; Chamber with tubular heat exchanger. Here, the most efficient removal of thermal energy and its transfer to the coolant takes place. Due to this, the gases entering the chimney are already almost cold. Gas generating boilers Pyrolysis Master TM: equipment series

Boilers of this brand are presented in two produced series.

Series "Premium". The design of such a boiler is made of 10 mm thick heat-resistant steel grade 09G2S. For greater protection and longer service life, the inner walls of the combustion chamber are protected with fireclay bricks. This provides the necessary thermal insulation and prevents the metal parts from over-expanding. The large area of ​​the heat exchanger creates conditions for optimal removal of thermal energy, thanks to which the surface of the boiler remains cold, and the efficiency is maximum.

Series "Standart". The boilers of this line are not inferior in quality and technical equipment. The difference here will be the overall dimensions, weight of the equipment and, accordingly, thermal power. In turn, they have a lightweight combustion chamber, due to the wall thickness of 8 mm.

Advantages of Pyrolysis Master boilers

Pyrolysis Master boilers are an excellent solution for autonomous heating of industries and residential facilities. Working on popular types of solid fuel, the boiler has a high efficiency and a fairly long service life.

Specifications

Today, the X-TEPLO portal presents its readers with an expert review of the updated line of pellet boilers popular in Russia, manufactured under the brand. The brand of these boilers has long won the trust of the consumer in the market, so we do not pass by, share our impressions about the updated PELLET series.

It is impossible to achieve revolutionary changes in pellet boiler technology today, so all of them, which is logical, are concentrated around the comfort of operation, as well as aesthetic advantages. Pyrolysis Master went both ways.

The first thing that the consumer notices is the appearance, which has been dramatically improved thanks to the new design. According to our information, the manufacturer involved European specialists in the field of industrial design to develop the design.

The second and more significant change was the new boiler automation. The updated controller in the new Pyrolysis Master line of pellet stoves, manufactured at a German plant in Poland, can now not only control the operation of the boiler, but also supports remote control through all modern communication channels, including a room thermostat. Now the consumer can "command" the boiler through SMS messages, using a computer via the Internet, as well as directly from the bedroom, setting a comfortable air temperature on the room thermostat.

Improvements also affected the burner, which in boilers of this brand is one of the most unpretentious pellet burners on the market in relation to the quality of the fuel used. On the manufacturer's website, you can find a video of the operation of the burners, having studied which, you can be convinced of the omnivorous nature of this design. However, changes in boilers affected not only in terms of unpretentiousness. It's about durability.

We requested photos of the new burner, which show that all the "dry zones" of the steel surfaces of the burner have become 2 times thicker. For the consumer, this means one thing - the service life of the burner without replacing consumables will be the same as that of the boiler itself. This improvement, in our opinion, is key.

Burner operation example

For those who want to get more information about these boilers, we suggest moving down the article, where we will tell you more about the model range and design. It will be interesting, join us!

Model range of the PELLET series

A series of hot water boilers with burners for burning pellets of any quality, developed in 2015, includes 15 models, different in thermal output, but similar in design. The power range of all presented boilers of this series is in the range from 15 to 500 kW, which allows them to be used for heating domestic, public and industrial buildings with a total area of ​​​​up to 5000 square meters. meters, and when installed in cascades, the heated area is not limited.

The design consists of the following main elements:

• steel boiler with a 5-way heat exchanger - it should be noted, the only one on the market;
• fuel bunker;
• conveyor with two screws for feeding pellets into the furnace;
• cast iron burner;
• fan for air supply;
• automatic and emergency safety devices.

As additional equipment, a chimney is required, the internal section of which depends on the power of the equipment and the maximum possible amount of combustion products.

Purpose of equipment

Steel heating boilers of the PELLET series are designed for heating the heat carrier in heating systems with a design operating temperature of up to 90 ° C and a pressure of up to 2.0 kg / cm 2, as well as for preparing hot water through an indirect heating heat exchanger. The choice of the required boiler power is made depending on the calculated heat losses of the building and the level of hot water consumption.

Fuels used

To obtain thermal energy, granular pellets of any quality are used as the main type. Additional types can be small wood waste, sunflower husks, etc. The PELLET DUO series provides for the possibility of burning firewood on the grate included in the delivery.

Design features

Especially for the PELLET series, a special design of the heat exchanger was developed, which forms a 5-way movement of hot flue gases inside the furnace. At the same time, the cooled coolant from the return line enters at the rear in the lower part of the heat exchanger and passes through it upwards, all the while moving towards flue gases with a higher temperature.

Thanks to this, it was possible to achieve a significant decrease in the temperature of the flue gases and increase the efficiency up to 92%. This indicator can be considered objective, because. the heat transfer area is really impressive.

In the words of the consumer, such a high efficiency means high savings in pellet consumption, and hence your money for heating.

The body is made of high quality boiler steel with a thickness of 6-8 mm and is characterized by high strength and durability. Thermal insulation inside the structure reliably retains heat and eliminates unacceptable losses to the surrounding space. For convenient maintenance of the furnace and cleaning it from soot, service hatches and sufficient distances between the elements of the heat exchanger are provided.

Steel fuel hopper and pellet feeder

In the basic configuration, the volume of the bunker is selected in such a way as to ensure continuous operation of any model during the day at maximum load without adding pellets. However, it is possible to order a bunker with an increased volume, up to 10 thousand liters. Loading of granules is made through the top reclining hatch.

Feeding into the furnace occurs by means of a mechanical device with two screws, which are located on axes of different heights. An air gap in the pellet supply channel to the burner brings the fire safety level up to 100%, eliminating the possibility of flame penetration through the transport channel into the pellet hopper.

The first upper auger takes the pellets from the fuel hopper and transfers them to the second auger below. The lower mechanism delivers pellets directly to combustion. The operation of the augers is separate and is performed automatically.

The fuel bunker can be installed on the right or left side of the boiler. This will provide more convenient access to the loading hatch in small boiler rooms.

Pyrolysis Master pellet burners use a horizontal type retort burner made of heat-resistant cast iron. Its design and operational advantages include:

1. automatic ignition using a heating element;
2. mechanical removal of ash residue after fuel combustion;
3. forced air supply for combustion, which ensures complete combustion;
4. long service life due to the use of heat-resistant materials of large thickness;
5. the possibility of efficient combustion of various types of granulated and other crushed dry fuels.

The automated operation of the combustion air supply fan increases the pressure of the flue gases inside the furnace and improves the draft in the chimney.

Summarizing the above about the burner, it must be said that it is not unique in design and corresponds to many analogues used in boiler brands popular in Europe. It is worth noting that such a tray-type device for burning pellets and biomass is very practical among all the solutions offered on the market.

Automation and security

Boilers of the PELLET series are equipped with automation manufactured by the Polish-German microelectronics plant, which produces almost all automation for boilers manufactured in Europe. The basic set of automatic control provides:

• timely rotation of screws for feeding granules;
• coolant temperature control;
• regulation of the amount of air supplied to combustion;
• air temperature control and required power level;
• control of the circulation pump of the heating system;
• regulation of hot water temperature in an indirect boiler or other indirect heat exchangers.

Additionally, each boiler of this series can be equipped with a control device via the Internet or sending SMS messages. If necessary, a room thermostat can be supplied with the ability to control the temperature in the room. Safe operation is ensured by the installation of a safety relief valve and an emergency thermostat.

Recommendations for the use of PELLET boiler systems in heating systems

Pellet boilers can be considered as alternative sources of thermal energy that can provide cost-effective heat supply instead of installed gas equipment. They are operated in a completely autonomous mode or when connected in parallel with already installed gas equipment. For the use of solid fuel devices, it is necessary to provide for a separate fireproof and well-ventilated room.

Boilers Pyrolysis Master PELLET 15, 20, 30, 40 and 50

This group of boilers is designed to provide heat in the heating systems of residential buildings of individual buildings with a total area of ​​up to 500 m 2. The presence of a basic fuel bunker will ensure efficient combustion of pellets during the day without reloading. At the request of the customer, it is possible to equip the hopper with a larger volume, which will increase the time between its periodic downloads.

To ensure normal operation, two rooms are required:

• a furnace or boiler room in which a boiler, a fuel bunker, a circulation pump and other necessary equipment are installed;
• fireproof ventilated warehouse for fuel storage.

The chimney can be free-standing or built-in (attached) to the building structures of the building.

The level of equipment automation allows the boiler to be operated with minimal human intervention. You simply pour the required amount of pellets into the fuel bunker, set the desired coolant temperature on the automatic controller, and that's it - the automation independently ignites the pellets, brings the boiler to operating mode and maintains the temperature you set. If pellets are added to the bunker in a timely manner, then the autonomous operation of the boiler will last until the end of the heating season.

Boilers PELLET 60, 80, 100, 120 and 160

A group of boilers with a heat output of 60-160 kW is designed for heating public, office, industrial, commercial and other buildings with a total area of ​​600-1600 m 2 .

Perhaps this is the most economical group of boilers, which is a strong argument for the commercial sector when choosing a boiler model. At high capacities, Pyrolysis Master boilers with high efficiency (92%) provide significant fuel savings, and in monetary terms, this is 10-20% less than the cost of buying pellets. Not to mention the opportunity to purchase the cheapest ones - any will burn. It should be noted that fuel costs are approximate and are taken in comparison with boilers that do not have such a developed heat exchanger.

Boilers PELLET 200, 250, 320, 400 and 500

This group of the most powerful boiler equipment with a capacity of 200-500 kW is designed for operation as part of heating systems for buildings with a total area of ​​2000 m 2 and the ability to work in cascades, which will allow heating any given area. Installation can only be carried out on the basis of agreed design solutions and by specialized installation organizations with the appropriate SRO approvals.

To store the necessary fuel reserves, a separate well-ventilated room should be provided. A solid fuel boiler plant can be placed in the same furnace together with gas or other types of boilers. In this case, the use of a single group of circulation pumps is allowed.

Unlike gas equipment, solid fuel pellet boilers are allowed to be installed in rooms whose floor level is below ground level.

The operation of pellet mills of this power group implies the organization of transportation of pellets to the operational bunker through automated transport systems. The manufacturer is ready to offer large bunkers for the main warehousing with screw conveyors to the operational bunker of the boiler.

Loading pellets into a complete fuel bunker is able to provide stable heating during the day at maximum load. At the request of the customer, the installation can be equipped with a hopper of increased volume up to 5,000 or 10,000 liters, which will significantly increase the pause time between periodic loads.

Conclusion

Industrial pellet boilers – Pyrolysis Master, FACI, Roteks

There are a large number of companies engaged in the production of industrial boilers on the domestic market. Especially popular today are industrial-type units operating on pellets. In this article, we will talk about three Russian manufacturers that produce such equipment: Pyrolysis Master, Faci, Roteks.

FACI

Pellet boilers manufactured by this manufacturer belong to the category of economical equipment, because. pellets of any quality (wood, buckwheat, shells of peanuts, almonds, pine nuts, coal, firewood, etc.) can act as fuel.

Pellet boiler FACI

FACI boilers are an environmentally friendly type of heating, they can be installed both in closed and open heating systems. You do not have to constantly monitor the operation of the equipment, they are very easy to clean.

The package of heating devices includes a volumetric bunker for loading fuel, and on the front side of the boiler there are doors for cleaning. All Faci boilers, in particular industrial ones, are safe to maintain and operate. This is due to their design and built-in automation. The units also have overheating protection.

All boilers have a twin-screw fuel supply system, which means that the flame will not get from the boiler into the bunker. If we compare traditional solid fuel units with FACI, then the latter produce the most economical heat.

Their productivity is high, the efficiency reaches 92%, which indicates that the fuel is burned to the end.

Another important advantage is that FACI pellet boilers are an environmentally friendly source of thermal energy. The design of the devices is such that the fuel burns completely, and in terms of flue gases and emissions into the atmosphere, the units correspond to class A, the best in Europe.

Industrial-type boilers include heating appliances with a power of 105 to 911 kW. Designed for heating and providing hot water in rooms ranging from 1050 to 10000 m².
They are made from high quality durable steel. Due to the fact that the design includes a three-row heat exchanger, high efficiency and energy savings are ensured. The heat exchanger is made of flue seamless steel pipes, which are immersed in water, they are located in the upper part of the combustion chamber, equipped with a downward screw. This indicates that the system is naturally protected from backfire. Devices can work on any kind of crushed fuel.

Specifications and functionality:

• automatic fuel supply mode (main) - pellets, crushed biomass;

Roteks

Pellet boilers Roteks are manufactured by ChZSK, a Russian manufacturer of pellet boilers for heating, modular boilers, assemblies and components for boiler equipment. The equipment is considered efficient and is in great demand among domestic users.

Pellet boiler Rotex

As distinctive features of this equipment, we can single out the presence of a retort burner, which is absolutely unpretentious to the quality of pellets, a three-way heat exchanger - vertical, allows you to keep the surface of the heat exchanger clean.

In this regard, Rotex pellet boilers are characterized by high productivity, the efficiency reaches 93%. If necessary, in specialized stores you can always find spare parts that are much cheaper than imported ones.

Industrial pellet boilers Roteks are presented in a series from 100 to 300 kW in the configuration "LUX" and "ECONOMY".

The technical characteristics of the heaters of both series with the same power do not differ.

Boilers belonging to "LUX" and "ECONOMY" operate on solid granular fuel, comply with the requirements of GOST 20548-87 and GOST 30735-2001, are fully automated. The advantage of the "LUX" series is the option of remote on / off, as well as SMS notifications about the operation of the boiler.

It can be concluded that all three manufacturers are not in vain occupying leading positions in the market, because. produce high quality equipment. When choosing industrial pellet boilers, it is necessary to analyze all the options well and, based on personal requirements, choose the best option. If you choose a boiler from the three proposed options, then, based on practicality and efficiency, the Pyrolysis Master equipment looks the most attractive. But the final choice is yours.

Boilers of the LONGLIFE series are produced in capacities of 18-250 kW. Are intended for burning of all types of solid fuel with the fraction suitable under manual laying of a fire chamber.

The firebox is equipped with water-filled grates and two doors for the convenience of filling fuel and cleaning the ash residue of combustion products.

The boiler heat exchanger has the largest heat exchange area in the class due to the surfaces that form a 5-way movement of gases in the furnace on the way to the chimney pipe.

Due to the developed surfaces of the heat exchanger, the boiler has a large capacity of the heat carrier, which allows it to act as a storage buffer and prevent the heat carrier from boiling in case of circulation disturbance.

The process of fuel combustion in the boiler is controlled by the controller through forced air supply using a modulated fan. The controller algorithms decide on the need for the current intensity of fuel oxidation based on the temperature of the coolant, taking this indicator through the probe in the heat exchanger.

Automation is made in Europe. At the same enterprise, almost all European brands of solid fuel boilers order serial production of controllers.
