How do kiln for garage wood-fired long burning his own hands

scheme devices of this group of heaters (also called producer gas) have many advantages over similar conventional assembly.If the reader has decided to establish in his garage wood-fired oven is a long burning (DW), so he is familiar with all its pluses and minuses.By the way, the latter is not so much, so the choice of just such a structure is justified.

How to mount the oven with wood burning long that provide at its assembly with his own hands - all the nuances of engineering solutions and its implementation the reader will learn by reading this article.

Features furnace operation

  • firewood in a conventional furnace burn through rather quickly, and this applies to all types of wood.In practice, you can increase this time only by limiting them to air.As a result, the "fuel" in the continuous burning furnace is not lit, as usual, and smoldering, and depending on the size and design features tabs device - from about 6 to 10 hours.
  • When traditional units burning process starts from the bottom, the furnace DG vice versa - from the top.As the burning of firewood, he gradually shifted lower and lower.Therefore, to ensure a continuous burning furnace process, it must be oriented vertically.This is one of its differences from the "stove".
  • Accordingly, ignition furnaces long burning - the top, through the air supply pipe.
  • To reduce the intensity of burning firewood and to make the process long enough, they need to be constantly "pressing", preventing flare flame.

choice of materials

bake When it comes to the garage, then the best option for the oven DG - iron.In fact, this modification is the same, well-known, small stove.Given the limited space in the model box, spread furnace brick hardly makes sense, and even more so in the garage collecting of metal sections or frame structure based on beams and planks, assembled by hand.What

consider

  • Recommended thickness of the metal used for the furnace body - not less than 4 mm.But this is for installations that are operated frequently.If you plan to use the oven regularly, you can reduce this setting, and (within reasonable limits, otherwise the body will burn through quickly).
  • When assembling the device from its minimum cross-section of the pipe - 30 cm
  • combustion products -. Through the furnace wall (for a square configuration of the body - through the back).Recommended chimney slope - 300 or more, or craving to be insufficient.For this reason, its cross section - 12 cm

chimney for the stove is better to do a long burning compound..Firstly, for ease of maintenance (cleaning) discharge channel gas.Secondly, the first leg (connectivity with the furnace) will be heated stronger than the other.Therefore, the wall thickness is selected for it within 2.5 - 3 mm.If you collect all of the chimney, it will weight design of this metal, and assembly of a long combustion installations will more expensive, if the iron will have to buy.

can mount the entire route to and from thinner metal, but in this case does not serve the chimney long - burned, and the operation would be less convenient.Therefore it is necessary to focus on the intensity of use of the oven.If the car owner in the garage spends a lot of time, it saves on the tube is not necessary.




How to assemble long burning furnace

Knowing the principle and method of operation of the furnace to ensure continuous burning, to construct the unit and assemble it with their own hands is easy.The photo and drawings presented a fairly simple model.For the stove body can take a metal barrel, the design section of the pipe, the balloon out of the liquefied gas, ready to box or a box of welded sheet metal - more than enough options.

n -1

Consider furnace manufacturing specifics on the wood long burning of a standard barrel for fuel.According to motorists, for the manufacture of the hands - the best option.However, the vessel wall thick enough, but if the oven does not work for days, then it will be enough for a long time.And in terms of maintainability - a good engineering solution.only the body is changing in the case of need, and all the "snap-in" remains the same.

What is needed for the stove

  • barrel.Metal
  • pancake (press) with a diameter slightly smaller than that of the housing.How much?He must move freely along the vertical axis.The practice of such furnaces shows that for long enough burning media thickness of 3.5 - 4 mm.
  • pipes.For the chimney - no less than 15 cm in section, enough to supercharge and 10. The length of the latter is chosen to be the height of the housing + (50 - 100) mm.
  • Ugolok- "fifties" (or channel) - 4 segment.The length of each - of the order of 15 mm.
  • metal sheet (grate).
  • box for disposal of ash.

Manufacturing furnace body

The technology is simple - the top of the barrel is cut, the edges are aligned.The result is as shown in Fig.

prepared and cover.

n -7

Its edges have to bend so that in setting in place she sat tight enough.In the center is cut an opening into which is inserted (or welded) pipe bend to boost.

n -8

His height - around 15 - 20cm.If the knee to make longer, it will be inconvenient to produce ignition of the furnace.

At the bottom of the barrels are welded corner pieces, which are put to the grate.All the rest, as for conventional stoves - the door behind which the drawer for ash removal.

Preparation chimney

n -5 The only explanation - you need to install the gate (valve), which will be governed by thirst.When ignition is open, and during operation of the furnace is covered so that the sustained and prolonged fuel burning tab was provided.Shiber easier to work if it is installed in the 1st lap.That is why the initial portion of duct height less than 150 mm do not desirable.

to flap securely lock in the user-selected position, you need to consider the elements of its fixation.In principle, their own hands to do it simply.

Hoods

experience of operation of the plant long burning this assembly indicates that the furnace duct length of less than 5 m weakens the thrust.That's it and need to be guided.Fixing the tribes across the length of the track is provided by backups from the same corner.

to the system can be periodically drained condensate at the lowest point of the pipeline valve is placed on the knee.For convenience, better to choose a ball type.

degree heat pipes

n -2 Their undesirable to mount on the wall, especially when trimmed inside the garage.As a rule, the most commonly used materials for lining of buildings - multi-layer plywood, thin board or MDF, chipboard.All such products - category "combustible".

Press

The metal pancake is done taking into account the opening of the pipe section of the boost.Uniformity of smoldering wood is provided over the entire area, including the specific position and the load.During operation of the furnace, with a gradual lowering of the press should not distort it.Therefore, from the bottom of pancake perimeter welded prepared corner segments (sill).This revision will provide its media stable orientation in the horizontal plane.

Operating Procedures furnace

  • dismantles part of the supply line, removed the lid and removed the press.
  • Incepted firewood.They are best placed vertically, as such a dense staging logs reduce the amount, which takes the air, and will contribute to their more prolonged combustion.
  • upper layer - flammable fractions (chips, small chips).Do not forget that the ignition - on top!Upper tab cut needs to be slightly below the level of the hood, or the burning will not.For investment ignition of wood, as in a conventional furnace, they can put a rag soaked in the solarium (or gasoline) paper.
  • Then - in reverse order: the goods - the first knee cap (if removable).

To start the installation long burning enough to throw on a piece of burning paper tab and see how the "grab" fuel.Thereafter, the maximum gate moves out and is made joining the entire duct.The characteristic crackling firewood suggests that it is time to close the damper.

As already could see dear reader, or build their own hands or operate a wood-burning oven long burning is not any difficulty.

Helpful hints

  • reduce warm-up time and increase space efficiency of the furnace can be, increasing the heat exchange surface.To this end, the oven body, on the sides is sufficient to weld the metal plates.
  • stopper in the lid of the furnace is desirable to leave (not brewed).It can be used as a sight glass to monitor the combustion process.
  • grate is simply your own hands.Metal sheet iron cut fragment corresponding to the diameter of the furnace.And not necessarily that it was a perfect circle.The grate drilled holes, and their number is chosen empirically.For standard 200 liter barrels approximate diameter of the holes - 6 - 8 mm.That's enough to ash poured down freely.

Good luck in the construction of the furnace and the warm garage!
