What does the Call Overfish look like and why is so popular

The Dutch’s arrival

Despite appearances, a straightforward construction has numerous benefits:

1. "Dutch" is able to quickly warm up from the smallest portion of fuel. At the same time, its overrun during the flowering after prolonged downtime is very small.
2. The design of this furnace provides for the use of a relatively small amount of material, so it is relatively easy. For comparison: a large Dutch stove is built of 650 bricks, while a large Russian – out of 2500. At the same time, the heated area for the “Dutch” is 60 m 2, while for Russian – only 45 m 2 . In addition, the principle of the Dutchki device can significantly reduce the initial dimensions – up to 0.5×0.5 m in plan. This advantage allows you to place a “Dutch” without fears on an inter -story floor.
3. The canal labyrinth in the body of the stove has a great resistance to reverse traction, so smoke when blowing wind into the pipe almost never occurs.
4. Although the Dutch furnace was originally created as a purely heating, it can easily be equipped with a hob – the combustion mode will not be broken.
5. The channel part of the furnace can be pulled up onto 2 floors (and some are pulled up to 4), while the efficiency will remain at the same level.
6. Features of the design, combined with a small thickness of the walls, exclude the development of significant temperature deformations in laying, so the Dutchman is undemanding to the quality of materials. Good brick (refractory) will only be required to build a furnace. The rest is sometimes laid out even from burnt or hollow bricks.
7. In the channel part, you can easily find an area with an optimum temperature for installing an oven or water heat exchanger.
8. Irregular use does not cause absolutely any harm to the furnace. At the same time, you can drown it, bypassing the accelerated phase – the masonry does not crack from this.

As you can see, this furnace has an impressive list of benefits. Nevertheless, it is not ideal in spite of this. This is how the price was able to obtain these benefits:

1. "Dutch" has very low efficiency – within 40%. For comparison: the Russian stove absorbs more than 80% of thermal energy laid in the fuel.
2. It is worth at least a little hesitating with the overlap of the bit after the flip, how the stove will immediately be protruded by cold air. It is tightened through the chimney with a canal labyrinth, which acts like a siphon.
3. "Dutch" is not designed to use broken fuel, completely burning in a short time. It should not be drowned, for example, reeds, straw, brushwood and similar materials: the lion"s share of the produced heat will disappear through the chimney. With the maximum effect, the furnace works on long -lasting fuel (firewood, coal, peat), and in smoldering mode.
4. When using inexpensive types of fuel with high ash, the chimney quickly overgrows soot.

When the firebox of a Coshendian oven is overly hot, carbon monoxide can escape into the space.

Structure device

One could describe the Dutch furnace’s full-right design as clever. The primary characteristic is that smoke gases are able to heat the brickwork more through the maze-like network of channels—named after the type of furnace through which they pass—rather than through the chimney itself. The figure illustrates the classic Dutch stove in its context.

Diagram of a Dutch stove device

It is nearly hard to seriously violate anything in the Dutch design, and intricate calculations are not necessary. As a result, there is no set sequence that needs to be adhered to precisely. Within certain bounds, it is sufficient to withstand the main size ratio.

The furnace heats up quickly because of two things combined:

• the area of the inner surface of the gas transmit is increased (due to the device of the canal labyrinth);
• Reduced material consumption of the furnace.

Keep in mind that the materials volume used is decreased within acceptable bounds because the furnace’s heat capacity is more than adequate. That won’t be sufficient for the entire day, though; you’ll need to submerge the stove at least twice.

Unlike many other furnaces, the output chimney canal is directed to the side rather than up; in other words, a pipe is not provided. Multiple furnaces can be connected to a single prefix (radical) chimney thanks to this feature. This was crucial for ancient Holland because the amount of tax there was determined exactly by the quantity of smoke pipes.

Because the firebox set is flat rather than arched, it is even simpler to manufacture the stove.

This is fascinating. Fires were common in Russia during Peter the Great’s reign because Russian furnaces had black fireboxes. With the intention of averting such incidents, the king issued a special decree demanding that stoves be built in the Dutch style. However, the stovers frequently only partially carried out the royal decree, creating stoves that only superficially resembled Dutch stoves. What was typical of the "Dutch" was the emphasis on tile decoration. Confusion resulted, and to this day stoves with a design that is distinctly "Dutch," such as caps and even some Russian varieties, are referred to as such.

The Dutch stove was altered by some inventors for various uses. G. The Utermark gave her a circular form, for instance.

The diagram depicts a simplified smoke turnover with three channels; however, in certain types of losses, there may be as many as twelve. Because the stove has a steel casing, the wall thickness could be lowered to ¼ brick. This significantly decreased the loss’s cost, which is why the "budget" section of the report was firmly reinforced. However, the oven’s heat capacity has significantly dropped at the same time, meaning you frequently need to drown one of these. Furthermore, because of the design’s characteristics, it overgrows soot rapidly, has a low efficiency, and strongly hopes.

Higher technical attributes are possessed by a Dutch inventor from the Soviet Union named E. Grum-grzhimaylo. In contrast to the loss, it has a grate and a cap in the supra-pound. The cap was incredibly economical; based on efficiency, it nearly reached parity (more than 80%) with the Russian stove.

The Big Dutch stove was converted into a small summer cottage to suit the needs of the homeowners of the houses in the garden plots; these furnaces come in various varieties.

Calculation of parameters

The furnace’s primary parameters are its heat transfer power and chimney size.

The specific heat of the fuel must be known in order to calculate power.

Table: indicators of the heat of wood

Wood	Meaning (kW*h/m3)
	At a moisture content of 12%	At a moisture content of 25%	At a moisture content of 50%
Poplar	1856	1448	636
Fir	1902	1484	652
Spruce	2088	1629	715
Birch	3016	2352	1033
Oak	3758	2932	1287
Aspen	2181	1701	747

Since a portion of fuel burns in fiery burning in about an hour, the furnace’s power while in this mode will be:

Where W is equal to vt x EUD x 0.63 x 0.4 x 0.8.

• W is the power of heat transfer of the furnace, kW;
• VT – Topic volume, m 3;
• 0.63 – coefficient of loading of a furnace chamber;
• 0.4 – efficiency of the furnace;
• 0.8 – a coefficient showing which part of the fuel burns in full.

Assume the firebox of the furnace measures 400 by 300 by 400 mm. Next, when medium humidity (25%) birch gorge fuel is used, we obtain power:

W is equal to 22.76 kW (0.4 x 0.3 x 0.4 x 2352 x 0.63 x 0.4 x 0.8).

The chimney section is chosen based on the determined power:

• with a thermal power less than 3.5 kW: 140×140 mm;
• between 3.5 and 5.2 kW: 140×200 mm;
• between 5.2 and 7.2 kW: 140×270 mm;
• between 7.2 and 10.5 kW: 200×200 mm;
• between 10.5 and 14 kW: 200×270 mm;
• more than 14 kW: 270×270 mm.

The chimney must have the same area as the designated rectangular sections if it has a round cross section, which can be obtained from concrete blocks with round holes or from sections of steel pipe.

It should be mentioned that a furnace’s power consumption in smoldering mode ranges from 10% to 30% of what is needed for intense burning. However, the chimney’s section should be carefully chosen based on its maximum power.

Necessary materials and tools

Two kinds of bricks are used in the layout of the stove.

The walls of the firebox – fireclay brick

Possesses a yellow hue and a high temperature tolerance of 1600 degrees.

Be aware that chamotum brick superficially resembles acid-resistant brick, which dishonest vendors occasionally utilize. Inquire about a certificate of purchase.

Chamotis brick sizes can differ based on the brand. Thus, the SHB-8 brand brick is 250x124x65 mm in size, the same dimensions as a regular construction brick. The Sh-5 brand’s Shamot brick is 230x114x40 (65) mm, which is a little smaller.

High-quality chamotal bricks can be identified by:

• fine -grained structure;
• lack of visible pores and inclusions;
• a clear sonorous sound when tapping a hammer;
• When falling, it is divided into large pieces (low -quality scattered into small crumbs).

Regarding the brick’s appearance, a darker hue does not always indicate a higher grade. The best qualities can also be found in a lighter chamotis brick; it all depends on the clay deposit.

It should be noted that stove ceramic brick M150, which can withstand temperatures of up to 800 degrees, can be used to lay out the top-throat part of the Dutch furnace due to its mild thermal regime (not to be confused with ordinary building brick).

High strength and heat resistance clinker brick can be used to build the furnace walls. For the price, it’s far more reasonable than a scam.

The body of the furnace

Together with the furnace, the remaining components of the system can be installed using ceramic chimney bricks or a medium-sized brick with a small fracture.

Brick for a ceramic stove

It is acceptable to use used materials.

Materials for clay solution

Sand

You can use river sand that has 1 mm grains, ideally angular. But you should use sand free of organic impurities if you want a long-lasting furnace that can last more than ten years. Such quality was previously exclusive to very expensive mountain sand, but you can now use a more reasonably priced brick in its place. It’s a ceramic brick, or shamot, shaped like the earth.

For masonry solutions, the first option is utilized, and for ceramics, the second.

Clay

The best preparation is made for masonry using chamotis bricks. Any ground clay with refractory qualities can be used to dissolve ceramic bricks; gray kaolin and Cambrian clay (either blue or gray) work best.

Suggestions. You must sniff before you buy to clay. Even if the smell is pleasant, if it is noticeable at all, the material has a lot of organic impurities and is not worth buying because it will quickly start to paint.

Clay varieties with an average fat content are preferred.

Tools

It is important to note the order of the tools: a flat rail with a 50×50 mm cross section, on which the risks are corresponding to the rows of bricks. It will be very easy to even out the masonry once four guards are fixed in the corners in a strictly vertical position (nails are driven into the seams).

Other tools: kelma, plumb, level, and hammer-chirochka, as part of a standard set of builders.

Preparatory work

Stoves with volumes up to 500 bricks can be installed without a foundation if the room’s floors are sturdy enough to support a load of up to 250 kg/m^2. This requirement is met by the tiny country cottage oven with a hob, whose construction we will go into further detail about.

However, if it is evident that the room’s floor lacks the necessary strength, it must be installed on a reinforced concrete foundation.

The foundation diagram for a large stove

Its depth is typically 400–600 mm, and on each side, the edges should extend at least 100 mm beyond the furnace’s outline. It is impossible to connect the structure to the building’s foundation because of the disparate shrinkage that could result in a skew.

The foundation needs to be ironed, or coated with cement, after it has been poured.

Concrete overflows the foundation

After the concrete ages, which takes about a month, it must be covered with two layers of waterproofing (either roofing material or nothing at all), at which point the furnace can be built.

You must first prepare a clay-sand mortar before you can begin laying bricks in their proper locations. The proper proportion of clay to sand is determined by the last’s fat level. To find out, they arrive as follows:

1. Having soaked the clay for a day, stir it to the test state, after which 5 portions of the solution are prepared with different sand content: 10, 25, 50, 75 and 100% of the volume of clay.
2. Twisting from each portion a 30-centimeter sausage with a diameter of 10-15 mm, it is wrapped around a blank with a diameter of 40-50 mm and left to dry at room temperature for 2 weeks.

One method of assessing clay’s quality

• a small net of cracks or their complete absence of a solution is considered suitable for any part of the furnace;
• large cracks, but not exceeding a depth of 2 mm: the solution is suitable for an elements of a furnace with a temperature of not higher than 300 degrees;
• deeper cracks and ruptures, the solution is considered unsuitable.

Once the ideal ratio of clay to sand has been established, the solution is prepared in the appropriate volume. In addition, clay is soaked for a day before being further ground through a sieve. Sand cleaned and sifted. The final mixture ought to resemble sour cream in consistency.

Step -by -step instructions with an order

The stove is arranged in the prescribed order, row by row.

Masonry Plans A tiny Burnic stone featuring a hob

Series No. 1 is subject to especially strict requirements because any mistakes made during installation could cause the entire structure to skew. The development of bricks should result in an exact rectangle, indicated by the diagonals being equal. All block upper faces should be in a strictly horizontal plane; the construction level is used to verify this.

Suggestions. Using a chalk circuit of the future furnace to apply the waterproofing coating before row No. 1 is laid will make it easier to shape it correctly.

First, it is advisable to arrange a row without a solution to determine the degree to which bricks complement one another. Blocks can be placed on top of the solution after fitting.

Using corner bricks to start each row more effectively is another trick. It will be simpler to correctly lay down the remaining blocks once they are leveled.

The blower door is mounted on the first row of the Dutchman right away. Its frame needs to be wound around an asbestos cord first. It will function as a seal to prevent the parasitic suction of air through the space between the frame and brick and permit the cast iron to expand freely when heated.

The door in brickwork will be secured with wire. It must be folded in half, twisted, and placed inside a box. Moreover, this wire is bent and weaves with the masonry after being placed in a groove that has been specifically cut in a brick (the upper edge).

Installing vertical landmarks will make it easier to lay out the furnace’s corners after you’ve finished working. This can either be an estimate, as previously mentioned, or four nylon cords stretched across the plumb line in between the nails hammered into the ceiling and the masonry joints.

Lay out the second row’s corner bricks on the designated landmarks before moving on to the rest of the row.

The order’s third row as well as a few others are highlighted in yellow. This indicates that refractory bricks are used to lay them out.

It is required to install a 300×200 mm grate on top of the third row’s bricks.

Place the fourth row’s bricks (the long end or rib) on a spoon. The red-colored blocks on the grades serve as supports for the chimney’s internal partition (see above).

The brick that will replace the food door on the back should be laid without mortar and slightly elongated. We call this brick highlighting. The flowering canal will have to be taken out of the masonry for access, and then it will be put back in after being cleaned.

The technique of using an extended brick to clean the stove

The furnace door needs to be installed in front on the fourth row. It is fixed in the same manner as a blower and has a seal.

Furnace door installation

Note: The wire holding the combustion door in place burns out quickly when it comes into direct contact with the flame. To avoid having to fix this element too frequently, use a strip of steel or tin in place of wire.

You only need to arrange the bricks in the correct order for Rights Nos. 5 and 6. You do not need to provide any comments. Just take note of the fact that blocks are arranged flat on a bed in the fifth row and on a spoon in the sixth, just like in the fourth.

The majority of Row No. 7 is arranged on the bed, but the back wall is perched on the spoon. Only the bed is covered in bricks in the subsequent rows.

The upper door must be blocked by the front bricks of rows No. 8. As indicated by the diagram, any blocks that hang over the firebox should be cut off. The fire with the furnace door open will veer back due to the inclined surface. The user will be able to use the Dutchwoman as a fireplace in order to admire the flame.

Row 9 needs to be moved back a little bit. As a result, when the furnace door is open, a sufficient counterweight is produced for the heavy cast iron door.

Underneath the hob, you must install a mineral lining above the ninth row. Asbestos, basalt, or kaolin cardboard strips can be used. The lining is put on top of a hob. Because clay and cast iron have very different coefficients of thermal expansion, installing it on the solution is unacceptable. Place asbestos cord in the space between the stove and the brick.

Take note! There is stiffness on the underside of the ribs of certain hob models. In this instance, the bricks where these ribs will be submerged should have grooves cut into them. Such a plate may crack along the line that runs parallel to and between the ribs if it is laid without any grooves.

The chimney’s source is located in row number 10. However, we won’t construct a brick pipe itself because doing so would prevent the Hollander stove from being lightweight. We install a stainless steel chimney because a brick chimney would still need to be doubled for a Dutchwoman, who is known for her copious condensate formation.

The valve has to be placed on top of the eleventh row’s bricks. It should be secured with asbestos cord, just like the doors.

The change from the rectangular brickwork section to the round steel chimney must be completed on the twelfth row. Thorough insulation of the chimney is necessary in order to ensure proper traction.

Suggestions. If you have extra money, you can buy a prefabricated smoke extraction system, or "sandwich ditect." Everything you need is included in the kit, including tee and umbrella sizes that match perfectly and provide good insulation.

Through the roof and ceiling, the chimney is removed to the street.

At least five meters should separate the height of its heading from the grate. Installing non-combustible heat-insulating gaskets between the pipe and wooden elements is imperative in areas where the ceiling and roofing intersect. It is necessary to completely seal the opening between the roofing and the chimney.

Note: The sandwich-making plant dummies come in sets that include an apron specifically designed to block the space between the pipe and the roofing in addition to cutting tools. Elements are easy to install because the kit includes comprehensive instructions.

If the floor in the space where the Dutchman is built is made of wood, it needs to be covered with a non-combustible material close to the furnace. Usually place an asbestos lining underneath a 1.5 mm thick steel sheet. The coating’s dimensions should ensure that it shields the floor within 1.2 meters around the furnace door’s center.

In front of the firebox, fasten a steel sheet.

Big Dutch furnace – how to build

Every component, including a gate, doors, and grate, is mounted similarly to the version that was just described. Naturally, the layout will be a little different because the chimney already provides heat to a smoke turnover system (a channel labyrinth). The diagram illustrates the order and layout of a large Dutch stove.

The large-call furnace’s order

Decorating the Dutch furnace

Tile decoration of the Cosrades stove has long been a tradition.

Examples of tile-decorated stoves

If this particular decorating technique is unavailable, a more conventional approach such as plastering and whitewashing the furnace would work well.

The Dutchman has to be elevated, one way or another, if the furnace owner’s room’s interior is at all significant.

Dutch final round

In a purely brick performance, it appears boring and infrequently used.

Features of operation

Due to the length of the gas transmitted during the reinforcement, a defining characteristic of Dutch furnaces is that the chimneys are removed completely through the chimney, with some of the gases—including toxic carbon monoxide—falling into the room. The temperature in the center of the front surface, or brow, must be watched during operation to prevent such occurrences; it should not rise above 60 degrees. The palm of your hand can withstand this temperature, but the brush’s back surface can no longer.

Knowing how to use a Cauldron furnace properly can improve your home’s insulation and heating considerably. Through adherence to the home masters manual, you can optimize the effectiveness and security of this heating system.

To begin with, installation must be done correctly. Potential risks are avoided and optimal performance is ensured by making sure the Cauldron furnace is connected and positioned in accordance with the instructions provided in the handbook. To preserve safety and air quality, this also entails appropriate ventilation.

Another important point the handbook emphasizes is routine maintenance. Frequent cleaning and inspection of the furnace can extend its life and prevent malfunctions. Furthermore, learning how to troubleshoot common issues can ultimately save time and money.

Additionally, the handbook offers insightful advice on maximizing energy efficiency. Easy fixes like turning down the thermostat and adding enough insulation to your house can save a lot of energy and money on utilities while maintaining a comfortable temperature in your house.

Ultimately, homeowners can take charge of their insulation and heating needs by learning how to operate the Cauldron furnace through the included handbook. By adhering to the specified guidelines, you promote a more economical and environmentally friendly home while also ensuring the safety and effectiveness of your heating system.
