We create fuel briquettes with our own hands at home for home heating: Review + Video

We create fuel briquettes with our own hands at home for home heating: Review + Video It is difficult to deny that compressed sawdust briquettes are one of the most efficient types of fuel successfully used for heating residential buildings. They have a high calorific value (about 5 kW is released from 1 kg during combustion), and have a low ash content. Such briquettes are very convenient in storage and warehousing, as they are compactly folded and take up very little space.

True, such fuel cannot be considered cheap: not every family can afford to heat their dwellings with firewood throughout the season. This raises a reasonable question - is it possible to somehow make wonderful fuel briquettes with your own hands.

This is especially true in cases where raw materials can be purchased almost at a bargain price. Fortunately, such techniques exist and may differ from one another. Let's consider some of them.

Making briquettes in production

To get a clear idea of ​​how to independently make briquettes, including for the Buleryan oven, you must first learn how they are made in the factory.

Raw materials

Any of the available methods precedes the preparatory stage, during which the raw materials are ground and dried.

The raw material is sawdust and some larger pieces of wood waste. Drying is carried out until the moisture readings are close to 8-10 percent. It is interesting that all kinds of agro-industrial waste (for example, husk or seed husks) and coal dust can also be used as raw materials for Eurowood.

We create fuel briquettes with our own hands at home for home heating: Review + Video The next production process is the pressing of sawdust, or briquetting. Today it can be done in two different ways:

  1. By extrusion;
  2. Forming briquettes on a special hydraulic press.

In both cases, as a result of powerful squeezing of the crushed wood, lignin, a special natural substance, begins to be released from it. It is he who becomes the binder for the friable mass of raw materials. The difference between the processes lies only in the different methods of squeezing. In one case, a hydraulic press is used, capable of developing a force of up to 300-600 bar.

From the force of this compression, the shredded wood heats up, and this contributes to the formation of a hard rectangular briquette.

In another method, extrusion, wood raw materials are poured into a special hopper of the unit, and, by analogy with a meat grinder, the screw moves into a conical working channel, which narrows. This is where the compression takes place, during which the screw press develops an incredibly powerful force of up to one thousand bar.

When ready, the wood made from sawdust in the form of hexagons comes out of the extruder. Before that, they undergo heat treatment, and are cut with a special knife to exact dimensions.

Fuel briquettes at home

It is completely unrealistic to imagine a situation when someone decides to purchase such a powerful unit capable of pressing briquettes at home.

Even if finances allow doing this, and raw materials will be obtained for free, it will be possible to recoup the acquisition only in the case of a large-scale sale of the manufactured fuel.

In other words, it is clear that it will not be possible to implement the traditional method, which would release lignin, at home. But numerous home craftsmen have learned through trial and error to use other binding materials.

Raw materials and preparation

  • corrugated cardboard, paper;
  • the cheapest glue, for example, wallpaper;
  • clay.

To make fuel briquettes at home, it is not at all necessary to purchase expensive pressing and drying equipment.

At home, they do it differently.

Savvy homeowners have the knack of pressing briquettes from a variety of available materials that can burn:

  • paper,
  • leaves,
  • straw,
  • cardboard,
  • seed husks and others.
  • Sawdust is placed in water, clay is added there in a ratio of 1 to 10, mixed well, then inexpensive wallpaper glue or soaked cardboard is added to the composition.
  • The mixture obtained in this way is placed in a homemade molding mold and squeezed as tightly as possible with the force of the hands.
  • The formed rectangles are taken out of the mold and laid out to dry outside, naturally.

Mechanism with a manual screw drive

We create fuel briquettes with our own hands at home for home heating: Review + Video The simplest press for the production of fuel bars, which you can make yourself, has a manual screw drive.

The design of this mechanism is extremely simple. But the performance of such a screw device is also low - this explains their low popularity.

A special molding container with holes is filled with the ready-made mixture, the screw is tightened tightly, creating an increased pressure.

When using them, a lot of time is spent on filling the container, twisting the mold and removing the formed briquette.

Mechanism with pushing out a brick

It is much easier and much faster to squeeze out the formed briquettes on another press. It is also homemade, but it has a long lever and a special device for pushing out a brick. To speed up the process, some do not weld one shape to the bed, but a pair.

Some craftsmen are able to make other equipment, more advanced. How to improve the productivity of a handheld machine? By installing a hydraulic jack instead of a manual drive.

Of course, it will take a lot of effort to make such a unit, but the result deserves it.

Pay attention! It will not be possible to create a pressure reaching at least 300 bar in a homemade press, even with the help of a hydraulic jack.It is unlikely that it will be possible to reproduce the factory technology at home without adding water.

Screw press

However, some craftsmen, despite the difficulties with the details, managed to make a screw press. With its help, it is possible to produce heating bricks of a fairly high quality.

Craftsmen write about this on the forums, but at the same time they note the rather high costs for the case of high-strength steel and the manufacture of screw parts. Of course, in this case you cannot do without an electric drive. An engine of at least 7 kW power is required.

Fuel briquettes at home - pros and cons

The reasons for the attractiveness of this type of fuel are quite clear

We create fuel briquettes with our own hands at home for home heating: Review + Video If a person has the opportunity to purchase cheap sawdust, or if suddenly he is the owner of a small wood production, then it is quite natural to want to make briquettes on his own.

Why not incinerate the actual wood waste?

  • The fact is that not every technique is capable of burning sawdust directly.

  • Usually wood fines burns very quickly and ineffectively in an ordinary stove, and even part of it falls into the ash pan.

Special equipment

To efficiently burn small wood waste, a special top-burning or shaft-type boiler is required.

  • It is practically impossible to make such one independently, the prospect of pressing waste into briquettes looks much more realistic. Although here, too, everything is not as simple as it seems;
  • Purchasing factory equipment is unreasonably expensive, and few people will be able to afford it;
  • It's cheaper to buy Eurowoods themselves;
  • Of course , a briquetting press can be made in a handicraft way. But the resulting fuel will be of low quality, and their heat transfer will not be so high.

Why is the heat transfer low?

We create fuel briquettes with our own hands at home for home heating: Review + Video The thing is, that it is practically impossible to reproduce the factory technology, observing all the nuances at home:

  • The resulting "bricks" have a low density and, accordingly, a small weight.
  • The specific heat of their combustion is almost three times less than that of wood.
  • Therefore, for the same heating, three times more homemade briquettes are required.
  • The process of making them takes a lot of time and effort. Although, if they exist, why not?
  • By the way, such fuel should be carefully stored so that it does not become saturated with moisture.

DIY fuel briquettes - yes or no?

We create fuel briquettes with our own hands at home for home heating: Review + Video Of course, you can make real fuel briquettes using home-made equipment.

The main thing is to have enough time for this, as well as free space for drying and storing products.

The availability of sawdust plays an important role: it is desirable that they do not have to be expensive to buy or to be delivered from afar.In this case, the idea would not make sense at all - it would be much more efficient to purchase a large truck of firewood.

Be that as it may, it's up to the owner to decide.
