Types of bath furnaces and features of their design

The popularity of brick furnaces for the bath is associated with several factors. First of all, compared to conventional metal or cast -iron stoves, a brick furnace is safer. When using metal furnaces, especially in a Russian bathhouse, situations often arise when the case gives a crack and part of the combustion and gas products seep through the crack of the firebox. This practically does not happen with a brick stove. And here it is necessary to separately focus on the fact that Kuznetsov’s brick stoves for the bath in their design have double walls of the furnace, and the channels for the removal of the exhaust gases are arranged so that all combustible gases burn out in the space of internal masonry. In this case, regardless of the weather, the stove thrust always works.

Second, metal stoves are cooling down very quickly. Unfortunately, the temperature inside a metal furnace will drop rapidly once you’ve finished adding firewood to it. With a brick stove, however, things are different because the brick holds heat for a long period of time. This means that when the heat process is finished, the furnace is sufficient to dry the steam room and other rooms and provide "comfortable" cooling without forcing the room to cool down quickly.

The third and most crucial point is that Kuznetsov’s brick stoves for the bathroom enable maximum efficiency while allowing for significant fuel savings. In actuality, you can use practically any fuel with the Kuznetsov model, and the useful action efficiency will be higher than with other brick and metal furnaces. Therefore, the Kuznetsov furnace’s efficiency is estimated to reach 90–92%, while most brick furnaces have an efficiency of 75–80%. The most basic Russian stove, on the other hand, can demonstrate an efficiency of 35–45%.

Kuznetsova Bath stove – design feature

Firstly, it should be mentioned that Kuznetsov’s bath oven is one of the adaptations of the hob heating system made to be installed in the bath as a steam room stove and heating device. Since the author was unable to avoid the design and construction of heating furnaces for more than 50 years, multiple models of these furnaces are currently available at once for the developer to choose from.

The unique arrangement of the firebox and internal components is what makes Kuznetsov’s bath stoves unique in terms of design.

It is a well-known fact that during the combustion of fuel, complex substances actively break down into simple combustible gases when the temperature reaches between 450 and 600 degrees. The majority of these gases enter the chimney of a typical brick firebox without even having a chance to warm up. For this reason, a visible black fog of soot and soot forms on the head of the pipe of such furnaces under normal circumstances.

Kuznetsov’s stove is arranged differently. First of all, the firebox here has a greater height. When heating the gases, part of the light gases moves to the upper part of the furnace or as the author calls it – the cap. Here, a ripening and mixing with oxygen, after which the process of secondary combustion occurs-the gases are almost completely burned, raising the temperature of the vault to 900-1400 degrees. Warm gases, after combustion, fall into the second cap-the neighboring cavity, where they gradually cool to a temperature of 250-400 degrees. After that, through the channels of the chimney are displayed out. This design provides an almost complete combustion of fuel while the temperature in the cap of the firebox reaches the maximum that allows for the normal combustion process even at low atmospheric pressure, and the gases that go out almost do not leave soot and soot pipe on the headline.

Tools and materials necessary for the construction of a bathhouse

The construction of Kuznetsov’s brick stove is unique in that it uses a special fireproof chamotum brick in addition to the typical full-bodied ceramic brick for masonry.

The truth is that since chamotum material operates between 1,500 and 1900 degrees, a chamotum refractor lets you maximize the burning temperature. However, this presents another issue: if the ball brick is easily located in a building supply store, then a special chamotum refleaced clay needs to be ordered ahead of time. The firebox and main furnace cap’s masonry is specifically designed to accommodate this type of refractory clay; cement mortar is never used in this situation.

Typically, the furnace’s exterior is constructed from red full brick. Its number can be determined simply by multiplying the quantity of bricks in the first row of the project’s order by a coefficient of 0.8 and then by the total number of rows in the project. Due to the internal channel device, the first, lowest row of the structure is fully filled, while other ranks, like 7 or 10, have less filling than the first. Typically, the average filling of the remaining rows is 0.8 in comparison to the first row. Thus, figuring out how many bricks there are in this manner is fairly easy.

It will be necessary to withstand specific sizes and proportions during the work, so a certain quantity of basalt cardboard or wool must be provided. The spaces between red and chamotis brick are filled with this substance.

Although the owners’ preferences and tastes are taken into consideration when choosing metal fittings, it is advisable to consider the advice of experts in this regard. Cast iron valves and doors are regarded as ideal. Naturally, steel has a more striking and elegant appearance, but cast iron can tolerate higher temperatures and does not deform as much as steel can.

On the other hand, they recommend using a specific refractory steel for the heat exchanger and the water heating tank in this instance. Cooking the steel’s stone is another recommended course of action. It is theoretically possible to use a cast-iron plate, but doing so would require increasing the volume of stones by 1.3–1.7 times.

Since brickwork creation demands precision, the following items must be in the arsenal:

  • Mason"s trowel;
  • Building level;
  • Marker thread;
  • Plumb line;
  • Bushhammer;
  • Brick cutting machine.

Expert stoves recommend carrying extra supplies, such as a hard-bristled brush and multiple containers for water and solution. Before adding a solution to the bricks, the brush’s function is to clean their surface; simply soaking the bricks in water adds water to the furnace’s already substantial weight. Furthermore, excess water in the brick mass won’t speed up the masonry’s drying process because a clay solution already dries slowly.

Of course, the most important thing is to have this dishonest plan for installing a furnace. The layout of Kuznetsov’s brick-by-brick furnaces is freely accessible, making it easy to download and print.

The procedure for building a furnace

The space is being cleared and the foundation is being torn to the foundation after the appropriate calculations and measurements are made in the room where the stove will be installed.

The furnace’s foundation may be set as a stand-alone structure or laid concurrently with the general construction of the building. The depth of the foundation must guarantee the strength of the construction, which means it must be deeper than the freezing point by 15 to 20 cm, in accordance with the guidelines for installing furnace foundations. It is advised to build a foundation that is 15–20 cm larger than the first row’s external masonry size. It is advised that the fill for a large bath stove be completed monolithically with reinforcement.

It is advised to examine the upper plane’s horizontal 15–18 days after pouring, once the foundation has reached the required strength and stability. You can arrange a layer of waterproofing and move on to laying the first row of bricks if the deviation is small and can be leveled with a solution. It is advised to use only roofing ground as waterproofing after bitumen composition has been applied to the concrete filling’s upper surface.

Device stove masonry schemes

Expert stovers advise beginning masonry at the zero instead of the first row. The uneven foundation’s drawbacks can be eliminated with this method, and the zero row also enables the structure to be strengthened with a lot of cement mortar.

The first row of Kuznetsov’s bath furnace is filled in, brick masonry is completed in accordance with the plan, and sutures should not be larger than 5 mm. Ordinary complete ceramic bricks in M150 standard sizes comprise the first row. It is important to remember that Kuznetsov’s furnaces are all made to work with masonry and standard-sized bricks. Curly bricks are an exception, as they are used to decorate corners, cornices, and other decorative protrusions. When working, GHOMOTIC bricks must frequently have their sizes adjusted, so you must maintain the brick-cutting machine beforehand.

There will frequently be marks on control sizes or control points when using masonry in the Kuznetsov’s furnace sampling plan for the bath. In this instance, the data will be for red brick and a notable difference in the chamotny. This is accurate; the only difference is that the linear expansion coefficients of ceramic red and fireproof brick change with heat. Additionally, the spaces between the chamotis and the outer brick are created to prevent the stove from crushing.

Fireproof chamota brick SB-8 or Sh-5 will be used for laying the furnace and cap, where the maximum temperature will be used. The first one measures 250x123x65 mm, while the second one comes in multiple sizes, measuring 230x114x40 mm.

The air bag where the air heating will start is formed by the second row. This is where the door is installed for ease of cleaning. In the future, steel wire that is woven into the holes of metal fittings will be utilized for dependable fixation.

A metal strip is used to provide reinforcement above the third row. It is fastened in corner blocks on dowels for ease of use.

The second row’s outlines are repeated in the third row.

In addition to forming a blowing set, the fourth row serves as the foundation for the firebox device.

A grate is positioned above the blower on the fifth row, and the bottom is constructed from chamotis brick. A 5-7 mm space is created and filled with basalt cardboard or wool between the furnace’s chamotary walls and the red brick outer masonry.

The furnace’s walls are removed in the sixth and seventh rows. In order to remove the cold gases from the second cap, a dry seam is created on the seventh row at the same time.

The vault over the furnace door is fixed in the ninth row.

Row nine is repeated in row ten.

The furnace set starts to form on the eleventh row.

Transverse chamotis bricks are arranged in the twelfth row; these will act as a catalyst to ignite simple gases.

The twelfth row is repeated in the thirteenth row, but instead of installing chamotis transverse bricks, the walls and outer walls of the furnace are removed. The start of the second channel’s formation in the second cap is another characteristic of this series.

The walls of the chambers of the caps are raised by the fourteenth and fifteenth rows.

The penultimate row, where a chamotis fire will be used, is the sixteenth row, which starts to form a set of furnace chambers with a cap.

The furnace set and the second cap chamber set are closed by the seventeenth row.

The second chamber’s cap set is entirely closed by the eighteenth row, creating a vault over a red brick furnace. Here, you need to pay close attention because there should be a gap of one to one and a half centimeters between the red arch and the chamotis brick arch.

The building of the chimney channels starts on the nineteenth row, where observation hatches are placed.

The only distinction between the twenty-first and twenty-eighth rows is that the formation of a direct chimney out of the building starts at the twenty-second. Other than that, they are nearly identical.

The twenty-ninth row creates the structure’s initial strapping, while the thirtyth row creates the final one. Building of the chimney is beginning from the thirty-first row.
