The concept and design of the boiler pyrolysis
Jetstream furnace for heatingdifferent rooms by burning wood - pressed bricks, logs and waste. On your device gasification boiler it differs from the classical solid-equipment, which also burns wood. Why install the Jetstream furnace: operating principles will help all to understand!
The furnace in the pyrolysis boilers divided into two parts. In the gasification chamber and the chamber load (the first part) with a lack of oxygen and pyrolysis wood burning, and burning down the escaping gases in the combustion chamber (the second part), which carried out the supply of secondary air. Minimizing heat dissipation occurs from the loading chamber.
These spaces are divided grate onwhich are briquettes. Primary air passes downwards through the layer of wood. Thus, the main difference between gas-generating boilers from other household devices considered top blasting.
Furnaces are characterized by such structuresincreased air resistance, so in most cases forced them to pull. Sometimes it is implemented for technological reasons with the help of smoke pump, rather than by the blow fan, which is more typical for small boilers.
The principle of gasification boiler
At the heart of the functioning of the boiler on the wood liesthe principle of thermal decomposition of wood, the essence of which lies in the fact that dry wood is able to decompose the solid residue (carbon) and the volatiles (gas) under the influence of external factors.
During the process that occurs in chamberDownload at high temperatures and lack of oxygen, the product gas is released from the resource. Wood gas passes through the nozzle, with mixing and burning with secondary air in a chamber at a temperature close to 1200 degrees Celsius. The flue gases pass through the convective part of the heat exchanger, giving its heat to the working fluid, and then output through the chimney.
Luggage loading and pyrolysis combustion boilerhave a refractory lining, which significantly raises the temperature inside the unit and creates ideal conditions for an efficient and high-quality wood burning.
Solid wood - the main advantages
To burn wood today use differentDevice: teploakamuliruyuschie furnaces, boilers air and water. Of all the equipment pyrolysis (gas generators) boilers are for consumers of greatest interest. The main difference from simple pyrolysis boilers solid models is the fact that they do not burn themselves firewood and charcoal, and the resulting gas. During combustion soot is not produced, and ash appears in a minimum amount, so the device needs to be cleaned less often.
The undeniable advantage of pyrolysis boilerperforms its ability to maintain a given temperature longer than can traditional boilers, due to the higher efficiency and increased loading chamber. Some designs of fuel on one tab can run for days.
The exhaust gases present lesscarcinogens. In the process of burning the pyrolysis gas reacts with active carbon, so the output flue gases are mostly a mixture of water vapor and carbon dioxide.
Another advantage of gas-generating boilerspower control is possible - 30 - 100%. Pyrolysis apparatus capable of utilizing certain wastes, almost without polluting the environment. For such wastes include rubber, plastics and polymers. But at the same time on the wood boilers are demanding fuel, need a power supply and have large dimensions.
What is the efficiency of pyrolysis boiler
Opening hours of the boiler on the wood is measured in a widewithin dependent on many factors - the temperature outside, the desired temperature in the room, house warming, humidity and the type of fuel, heating system design accuracy. But one thing is certain - much more efficient gas-generating boilers traditional.
When burning wood, including wet, notturn reach temperatures as high as when one resultant combustion gas timber. Moreover, the combustion gas requires less secondary air, whereby the temperature rises, and thus increases the time and efficiency of combustion. In addition, pyrolysis gas combustion process easier to manage.
On the fuel for the gas-generating boilers
For burning wood is used that haslength 380 - 450 mm and a diameter of 100 to 250 millimeters. Fuel briquettes should be of a size - 30 to 300 millimeters. Small wood waste and sawdust can be burned together with wood, but they should take no more than 30% of the loading chamber. These boilers can burn wood, which is different to 40% humidity.
Pyrolysis boilers should drown drierwood, only in this case is provided by the work of the unit at maximum capacity and service life is increased. Wood with a moisture content of 20% is characterized by a calorific value of 4 kW per hour per kilogram of wood, wood with 50% water content differs combustion heat of 2 kW per hour per kilogram of wood.
Thus, the heating value fuels abilityIt is dependent on the presence of water in the wood: Useful energy content of the briquettes significantly decreases with increasing water content. In this fuel consumption is doubled.
Make Jetstream furnace with their hands
Heating boilers burning wood pyrolysis inRecently becoming more popular because it removed the dependence on volatile natural gas tariffs. Of course, the market has a good gas-generating apparatus with a good performance, but their cost is still quite high, and that confuses consumers. The last building exhibition easy boiler domestic production cost is not less than one thousand dollars. That is why many consumers prefer to do Pyrolysis boilers with their hands.
To make your own wood-fired boiler, enough to have a desire and an essential tool! Of course, you have to spend a lot of effort. But everything is possible.
To get started is to gather as much information about theThis heater and its features. It is necessary to calculate and decide in advance what type of combustion is optimal for a particular building - to grate or a slot burner. Then, to visit a specialty store and purchase the necessary details. , Such materials need to produce Jetstream furnace:
- Pipe from steel thickness of 4 mm;
- 4 mm sheet steel;
- some shaped tubes;
- 20 mm round rod;
- centrifugal fan;
- fireclay bricks;
- equipment that regulates the temperature;
- nuts and bolts;
- Asbestos cord.
Drawings and diagrams of gas-boilers
The exact amount of material can be calculated on thedrawings. On the Internet, this subject has paid a lot of drawings and literature. If you follow this stuff, you get a passable aggregate. Scheme pyrolysis boiler needs to designate the furnace heat exchanger and the water feed point. Do not seek to create a diagram of an apparatus on the wood from the ground, it is better to use the concept and make it just a few adjustments and changes.
By making its gasification boilerhands as a basis we can take the scheme of the heating unit to 40 kW, which was developed by the designer Belyaev and then optimize it for laser cutting with fewer parts used. The device design can be changed so that it remains constant internal volume.
However, it is desirable to significantlyincrease the heat exchanger jacket. Next you need to connect all the details of the future of pyrolysis boiler, clearly following the drawing. In this case air is used as a coolant, and it can heat the room without heat.
Optional leak-proof pipesbecause the wood-fired boiler and the possibility of leakage razmerzaniya uncharacteristic heating system. Thus, this product is considered to be an ideal solution for installation in the country, where it will sink only occasionally.
After collecting the scheme of the boiler, you can startits installation and further tests. Correctly manufactured gasification boiler should go to the desired mode quickly, and the heating system must be warmed for a maximum of thirty minutes. In this case the room temperature usually rises very quickly.
Advantages of pyrolysis boiler Blago
The boiler designed Blago inventor BlagodarovaYu, who told about the benefits of his creation. For the duration of firewood burning at maximum calorific gas generating unit exceeds Blago other boilers.
In this model, grate completelycover the bottom of the fuel bunkers. Therefore, when there is a high natural draft combustion heat and a longer period of burning due to the layout of the fuel bunkers that make it possible to increase the amount of fuel bunkers, without causing damage to the efficiency.
The device allows the fuel pyrolysis boilerburning in one of the two combustion chambers, and the third gazitsya. Blago device is non-volatile and always gives the required power. Implemented fat burning compounds phenolic groups - tar, resin alcohols, essential oils.
Installed in the combustion chamber of the rails protrudegood heat accumulator. The pyrolysis boiler can burn peat briquettes, sawdust and coal. During low temperature combustion in the chamber to enclose the fuel can be continuously maintaining optimal indoor temperature.
Thus, despite the fact that the court of the 21stcentury, people still turn to firewood as a natural resource for heating. Now I understand why all of the solid pyrolysis boilers devices for the population are of greatest interest.
