Build a Dutch oven with your own hands

Job Stages

Scheme of masonry Dutch oven is simple enough, the materials used do not have special quality requirements. You can use a regular full-bodied ceramic brick and medium-hard clay-sand mortar of the consistency of thick sour cream. The masonry work can be performed by any novice craftsman who knows how to lay a straight wall with jointing.

Preparatory work

Before folding a Dutch oven with their own hands, perform a marking under the support of the future heater. It should be a separate structure, not connected with the foundation of the house. And it is desirable to build it at the stage of construction of the main building. Otherwise, you have to raise the floor and cut an aperture in the floor boards, 10-15 cm on all sides of the furnace base.

Place the material close to the place where the oven is to be built, so as not to interrupt the work process. All aggregates of the concrete and masonry mortar must be sieved and cleaned from foreign particles. Sand and gravel, if necessary, sow dry, but clay should be soaked in advance for a few hours and then rubbed through a metal sieve. At hand should also be a scheme of laying the rows of a hollandaise stove for the house and its chimney.

Making the foundation

The hollandka oven weighs less than other models of brick stoves, but still needs a high-quality and reliable support. A good option for the foundation for her would be a monolithic reinforced concrete structure in the form of a slab.

The algorithm of actions in the arrangement of the foundation for the hollandaise stove is as follows:

  • Performing the marking of the boundaries of the future support;
  • Excavating the excavation with a depth of 60 cm;
  • Sealing the bottom of the excavation;
  • filling crushed stone cushion 15 cm thick on the bottom of the excavation with layer-by-layer compaction;
  • installation of the formwork 20 cm high;
  • fastening of the polyethylene film for waterproofing to the walls of the formwork;
  • installation of one row of reinforcement mesh over the entire area of the monolithic slab at a height of 6. 7 cm from the surface of the macadam base. You can lift the mesh with wooden poles or metal pins by hammering them into the ground;
  • installation of vertical elements of reinforcement in the corners of reinforcement mesh cells with fixing at the joints with a tying wire
  • concrete pouring into the prepared formwork;
  • leveling the upper plane of the base;
  • Ironing the freshly laid mortar with a layer of dry cement 2. 3 mm thick.
  • removal of the formwork 7 days after the initial hardening of the material.

Before laying the main elements of the Dutch oven with his own hands, the concrete must reach full strength for 25. 30 days.

Mortar and brick

To improve the adhesion of bricks with mortar, as well as to ensure that the brick does not absorb excessive moisture from the masonry mixture, it should be completely moistened before laying, completely immersed in water for a few seconds.

When preparing the clay-sand mortar for masonry furnace, it is necessary to strictly observe the proportions of the components. Otherwise, the mixture will not be plastic enough, and masonry joints will not be able to withstand long-term exposure to condensation, will quickly crack and decay.

As the main binding component in the composition of the mortar is a natural material. clay with low m sand (fat). It is not afraid of high temperatures, when drying forms a strong homogeneous layer, perfectly bonding with each other brick surfaces. Only unlike Portland cement, it must be prepared in advance, soaked in water for at least 24 hours, and dries such a mixture 6. 7 days or more, depending on external conditions.

The proportions of the mortar for masonry brick oven hollandka for dacha are as follows:

  • For the furnace chamber, where the temperature is the highest. the ratio in the mixture of clay and sand should be 1:1;
  • For the construction of the body of the device, the chimney. 1 portion of clay to 2 parts of the sand.

Masonry and description of the masonry

Presented furnace layout of the Dutch oven without a stove, suggests the construction of a medium-sized structure, which can heat a private house of small area.

Description of the framing of the Dutch oven without a hob:

No. of rows Description
1 Brick is laid dry, and the level of the bed is checked. Then fill in the row from above with clay and sand mixture.
2 Beginning of the ash-pan and vertical gas ducts formation, installation of the clearing door.
3; 4 Installation of the ash door. To frame the door more firmly use a wire, embedding it into the joints Thermal insulation stove cast iron perform basalt gasket or asbestos cord.
5 Installing the angle steel cross pieces that will hold the ashpan roof.
6 Overlapping of the ash pan, installation of the grate.
7 11 Shaping the furnace, lining it with fireclay bricks, installing the furnace door the same way as the ash door.
12 14 Overlapping of the furnace chamber, expanding of the furnace body.
15 16 To install another door for cleaning the oven ducts. Providing a bypass for the heated gas to escape from the center channel to a channel closer to the back of the stove.
17 18 Dividing the central part of the flue into two channels. Overlapping of the heat exchanger at the rear.
19 25 Further shaping the heat exchanger.
26 29 Overlapping arrangement. From the 27th row onward, the internal space of the unit is narrowed down to create a more organic connection to the chimney.
30 Installing the metal damper

There are a few more options for ordering:

Chimney requirements

Start laying the flue pipe from the top of the stove, having previously installed the chimneypiece. The masonry technology is the same as in the construction of the walls of the enclosure, but there are some features:

  • For the construction of the chimney, you must use only whole bricks. Laying of quarters and halves will lead to an increase in the joints, which will reduce the level of reliability and safety of the construction as a whole;
  • To use fireclay bricks for the lining, laying them on the rib;
  • The height of the pipe depends on the configuration of the roof, but to ensure good draft in the furnace should be at least 3 m;
  • The distance between the wall of the house and the chimney must be at least 40 cm, and in the area of passage through the ceiling and roofing design must have an extension and thermally insulated asbestos or lead apron;
  • Masonry chimney should be carried out strictly in accordance with the poryadovka, the joints between the bricks carefully caulked to ensure maximum possible draught and heat rejection, and to avoid penetration of caustic products of combustion into the room.

Dutch heating and cooking stoves

The principle of all furnaces Holland is elementary heated air goes on the artificially lengthened way to the chimney, but the scheme designs are different:

  • Rectangular, circular.
  • Sizes.
  • Presence of additional equipment (a stove, an oven, a cot).
  • Gas distribution systems: multi-channel and bell-shaped. The latter is more effective, since it has a high efficiency of combustion of fuel, the heat stays in the chambers. Cold air that enters the heated oven passes through, bypassing the chambers. Multichannel system, in turn, is easier to erect, the number of channels can be up to six.

With hob

This design differs from the typical design in that it has a cooking surface 35 rows from the furnace. The best material for this part is 58 mm thick cast iron plate.

The stove can be solid, just for heating food, or it can have cooking plates. There can be more than one burner.

With a cooking top and an oven

This design of the Dutch oven is also equipped with an oven. The oven can be installed above or to the side of the hob.

The first position is preferable, because in this case, the hot air evenly envelopes the whole area of the oven. Located at the side of the furnace, the structure is heated predominantly on one side.

Came to us from the depths of centuries Dutch stove, shown in the photo. the best option for the novice craftsman or ordinary homeowner. Its channel system is used in modern heating furnaces and fireplaces, as it is one of the most successful solutions.

Classic Dutch oven is not equipped with a hob or oven and consists of the following main parts:

  • medium size firebox with grate
  • ash chamber with an ash door;
  • system of vertical or horizontal channels;
  • chimney.

Two variants of the oven model show the operation principle. Wood is burned in the firebox and transmits heat to the room through the brick walls, while the heated flue gases travel through a system of ducts until they reach the chimney. In the chimney, the combustion gases cool down, heating up the furnace body from top to bottom.

How attractive is the device of Dutch stove:

  • Simplicity of masonry in comparison with pyrolytic or bell heater.
  • The bricks can be made of any quality ceramic bricks, as long as they are corpulent.
  • Thanks to the repeated poryadovka stove rises to the necessary height and is able to heat simultaneously 2-3 floors.
  • The construction is notable for its small dimensions in plan.
  • In the chamber wood of any quality burns, and a network of channels quickly warms up a rough and heated room.

Over time, craftsmen have improved the Dutchman, adding to it a hob with an oven. This was also the prototype for a round channel stove, 1m in diameter, inside an iron casing, as shown in the photo and diagram.

Round variety

In the model range, among the rectangular variants with and without the stove, the round Dutch oven stands out. Its specialty is the double walls: the inner cylinder of small diameter is closed from above with a metal casing. Modern constructions have the following structure:

  • The chimney consists of three or five vertical channels, sometimes it is made screw-shaped.
  • Deaf furnace tries to make as much as possible volumetric, to have less need to add fuel.
  • The brick frame is wrapped with a case of smooth or corrugated steel sheets.

Hollandka in a metal casing has the following advantages:

  • The model is popular due to its simplicity and low cost; it is not difficult to assemble it with your own hands, and relatively few materials are required (the wall is laid in a quarter of a brick).
  • The stove is efficient and fireproof at the same time. Even if the brick wall starts to collapse, the sparks will remain within the steel case.
  • Minimum size. Thanks to the round shape and the small (1 m) diameter, the model fits harmoniously into the space of even a small room. It will not interfere with any location: in a corner or in the center of the room. Most of the useful space can be saved if you put the device between the rooms.
  • Design possibilities. If you do not like the metal casing, it can be decorated: tiled with ceramic tiles, painted or covered with plaster.

In the disadvantages write the following features:

build, dutch, oven, your, hands
  • Increased fuel consumption. A round stove needs 25-30% more firewood than a Russian one. Therefore, its installation is justified in case of occasional use, for example, in the country house or summer cottage. In country houses, a Dutch oven with a hob will be especially useful.
  • High heat output. A round stove heats up quickly, but it also cools down quickly. Cladding with heat-resistant materials can help to slow down the process.
  • The steel casing makes it inconvenient to clean the chimney.
  • Due to problems with the draught, deaf furnace and improper maintenance, round Dutch oven often smokes.

Materials required

Dutch oven with his own hands is laid according to a certain technology. To properly put it together, we will need the following materials:

  • Sand;
  • Construction clay;
  • Brick ordinary and fireclay bricks for the furnace;
  • Water;
  • Sliders;
  • Doors for furnace and ash door;
  • Doors for cleaning;
  • Steel wire;
  • Fire grate;
  • Asbestos cord;
  • A strip of steel half a centimeter thick;
  • Crushed stone, rebar and concrete or bricks for the foundation.

Possible difficulties

Despite the simplicity of the device, the construction of a Dutch oven requires theoretical and practical skills in this area. Inexperienced craftsman can make a mistake at any stage from the selection of a suitable scheme to the purchase of materials and directly laying. The price of a mistake can be both minor external defects and malfunctioning of the finished chimney.

Furnaces are sources of increased danger. Any mistakes made during construction are fraught with risk to the health and life of the household. The key to high efficiency and safe operation of hollanders is calculation and installation work performed by qualified specialists.
