Make pyrolysis boiler with his hands: economic production and exploitation

problem heating in the absence of cheap electricity and coal, as a rule, be solved with the help of wood.In connection with the rise in price of a natural resource such as natural gas, its use may be a significant impact on the family budget.People who are faced with the gasification of their private homes, are beginning to look for alternative sources of heat.And help comes pyrolysis boiler built with his own hands from the available materials - wood-fired boiler that runs on most cheap type of fuel.


concept and design of the pyrolysis boiler ↑

Pyrolysis boiler is intended for heating different rooms by burning wood - pressed pellets, firewooda

nd waste.According to its gasification boiler unit differs from the classical solid-equipment, which also burns wood.Why set the pyrolysis boiler: the principle of operation will help all to understand!

Why is pyrolysis boiler
constructive scheme and the principle of pyrolysis boiler

in pyrolysis furnace boilers is divided into two parts.In the gasification chamber and the chamber load (first part) with a lack of oxygen and pyrolysis wood burning, and burning down the escaping gases in the combustion chamber (second part), which carried out the supply of secondary air.It occurs minimize heat dissipation from the loading chamber.

These spaces are divided grate, on which the briquettes.Primary air passes downward through the layer of wood.Thus, the main difference from other gas-generating boilers of household is considered to be an upper blasting machines.

furnaces such structures are characterized by high aerodynamic drag, so in most cases they are forced traction.Sometimes it is implemented for technological reasons using exhaust fans, and not by blowing fan, which is more typical for small boilers.

The principle of gasification boiler ↑

the functioning of the boiler on the wood on the 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 a volatile part of the (gas) under the influence of external factors.

How does pyrolysis boiler
How does pyrolysis boiler

During the process that takes place in the chamber load at high temperatures and lack of oxygen is released from the resource generator gas.Wood gas passes through the nozzle, mixing with the secondary air, and burning in a chamber at a temperature close to 1200 degrees Celsius.Flue gases pass through the convective part of the heat exchanger by giving its heat to the working fluid, and then output through the chimney.

combustion chamber loading and pyrolysis boilers have a refractory lining, which significantly raises the temperature inside the machine and creates the ideal conditions for efficient combustion and high-quality wood.

Solid wood - the main advantages of ↑

To burn firewood now use different devices: teploakamuliruyuschie furnace, boiler air and water.Of all the equipment pyrolysis (gas generators) boilers are of most interest to consumers.The main difference from simple pyrolysis boilers solid models is that they do not burn yourself firewood and charcoal, and the resulting gas.During incineration, no soot is produced, and ash appears in a minimum amount, so the device needs to be cleaned less often.

undeniable advantage of pyrolysis boiler performs its ability to maintain the desired temperature longer than traditional boilers can, thanks to higher efficiency and increased loading chamber.Some designs on one tab fuel can work during the day.

is present in the exhaust gases is less carcinogens.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-boiler is the possibility of power adjustment - 30 - 100%.Pyrolysis apparatus capable of utilizing certain wastes almost no polluting the environment.For such wastes include rubber, plastics and polymers.However, with this wood boilers demanding fuel, they require power and have large dimensions.

What is the effectiveness of pyrolysis boiler ↑

Hours wood boilers is measured over a wide range depending on many factors - the temperature outside, the desired temperature in the room, house warming, humidity and fuel type, the accuracy of the design of the heating system.But one thing is certain - much more efficient gasification boiler traditional.

When burning wood, including wet, do not get enough to reach high temperatures as obtained from the combustion of wood gas them.Moreover, the combustion gas requires less secondary air, whereby the temperature rises, and thus increases the time and efficiency of combustion.In addition, the process of combustion of the pyrolysis gas is easier to manage.About

fuel for gas-boilers ↑

For burning wood is used that has a length of 380 - 450 millimeters and a diameter of 100 to 250 millimeters.Fuel briquettes should have such size - 30 to 300 millimeters.Small waste wood 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.

Fuel gasification boilers
Fuel pyrolysis boiler

gasification boilers to heat should be more dry wood, but in this case is provided by the machine, the maximum power and service life is increased.Wood with 20% moisture content is characterized by a calorific value of 4 kW per hour per kilogram of wood, wood with 50% water content of different calorific value of 2 kWh per kilogram of wood.

Thus, fuel efficiency 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 pyrolysis boiler with his hands ↑

Heating boilers burning wood pyrolysis in recent years become more popular because removed dependence on volatile natural gas tariffs.Of course, the market has a good gas-generating apparatus with a good performance, but the cost is still quite high, and that confuses consumers.At the last exhibition of building a simple boiler domestic production cost is not less than one thousand dollars.That's why many consumers prefer to do Pyrolysis boilers with their hands.

tool for ↑

to make their 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 this heater and its features.Should calculate and decide in advance what type of burning is optimal for a particular building - on the grate or the slot burner.Then worth visiting a specialty store and buy the necessary details.To make pyrolysis boiler will need these materials:

  • tubular steel with thickness of 4 mm;
  • 4 mm sheet steel;
  • several shaped tubes;
  • electrodes;
  • 20mm round rod;
  • centrifugal fan;
  • fireclay bricks;Automatic
  • that regulates the temperature;
  • nuts and bolts;
  • asbestos cord.

drawings and schemes of gas-boilers ↑

exact amount of material can be calculated based on the drawings.On the Internet, this subject has paid a lot of drawings and literature.If you follow this stuff, you get a reasonable unit.Scheme pyrolysis boiler needs to designate the furnace heat exchanger and the feed point of water.You should not seek to create a diagram of an apparatus on the wood from the ground, make better use of the concept and make it just a few adjustments and changes.
