Which is the insulation of the hanging kang or the soil kang, and the method of the rural fire kang

Hanging kang insulation. Hanging kang - the new kang stove is reasonably designed in accordance with the scientific principles of combustion and heat transfer: the thermal balance and economic operation of the kang stove are optimized, the relative distance between the furnace, the pot wall and the stove and the hanging fire height, flue and ventilation, and the structure of the kang are reformed, and the thermal insulation measures are added to the kang stove, the effect of waste heat utilization is improved, and the heating surface and heat dissipation surface of the kang are expanded.

Therefore, the structure of the new kang stove is reasonable, the ventilation is good, the firewood and grass are fully burned, the stove is on fire quickly, the heat transfer and heat preservation performance is good, and the thermal energy utilization rate of the kang stove reaches about 50%. Therefore, the new kang stove saves fuel, saves time, is good for burning, hot on the kang, warm the house, easy to use, safe and hygienic.

In the north, a sleeping utensil made of clay or bricks to protect against the cold during sleep is called a "fire kang" (土炂).

Disadvantages of "ondol": waste of effective resources (wood consumed during heat production, etc.); Not environmentally friendly (when burned, it produces pollutants that have an impact on both people and the environment); High labor intensity of heating supply (manual operation); Temperature control is not easy to grasp; The scope of application is not wide (limited to rural areas only), etc. When burning the kang, you need a stove, the kang is not easy to burn, and most of the problems will appear on the stove.

Tukang, a rectangular platform made of adobe or brick for sleeping in northern rural areas. There is a mat on the top, and there is a hole below, which communicates with the chimney, and can be heated by a fire. There is usually a stove next to the kang that can be used to boil water, but it is not usually used for stir-frying.

Due to the great changes in the weather in the north, the characteristics of the kang are warm in winter and cool in summer, and there will be no phenomenon of a child in the south giving adults a "warm bed", but it should be noted that most people in the north are angry, so people from other places often have nosebleeds when they come to sleep on the kang.

Fiery earthen kang.

Warm earthen kang.

Wide earthen kang Warm earthen kang.

Warm clay kang, fiery clay kang, warm clay kang.

Burn a fire below, sleep above. Warm earthen kang.

The earthen kang is a rectangular platform made of adobe or brick for sleeping in the north. There is a mat on the top, and there is a hole below, which communicates with the chimney, and can be heated by a fire.

There are many clay kang in the Northeast or rural areas, which are mainly used for heating, and can be used to burn firewood and warm and dry on the kang.

It's the same as the bed in town, except that you don't need an electric mattress!

The earthen kang is used for Northeast people to cook and smoke. The kang is hot. It's also very comfortable for people to sleep on.

Du is even more used to buy things, there is nothing.

The structure of the kang is far more complex than the bed, and the building method is also different, there are hole kang, flower kang and hollow kang.

The hole kang is to build a few small walls on the ground and eight rows of bricks are about high, the space is divided into several tunnels, the two ends are left empty to make the road communicate, and the adobe, stone slab or red brick is covered, and the cover is covered with reused sand and mud or white ash and the like.

Hua Kang is the development of the hole kang, the small wall is only half the height, the red bricks are all over the support, the red bricks can be used as the cover, and the rest method is the same.

The hollow kang is more advanced, only supported by a few columns of red bricks, covered with several large cement slabs, and the rest of the method is the same as the hole kang and the flower kang. It is said that the hollow kang is advanced because it has a large internal space, and it is not easy to be blocked by fireworks and ashes.

All kangs have a feature that one end leads to the chimney and the other end has a stove.

The kang in the northeast is made of bricks, and in order to make the kang fire in the northeast can be particularly hot, a curved flue is used in the kang setting, and only the original old people can make a special pan kang.

The surface of the Northeast Kang is paved with kang mats, and the kang mats are woven with sorghum straw, and the more you use them, the brighter they become. After kraft paper began to enter life, people with conditions began to paste the kang with kraft paper, and brush it with clear oil, so that the kang surface was bright and clean, and the effect was many times better than that of the kang mat. (It is also common to have floor leather.)

It's getting more and more exquisite. ）

The Northeast Kang is not only for sleeping, but also for heating. In winter, there are few things on the kang surface, and the bedding and everything must be rolled up and stacked and put in the kang cabinet, so that the big kang can dissipate heat, and the heat dissipation effect is good, and the house can be warmer.

1. Explanation of the noun of the kang bed:

The kang bed is not actually a bed, but a wooden seating combination for receiving guests, with a long low table in the middle and a chair at each end.

Second, the practice. 1. It is made of clods of soil and wheat straw mud.

2. Stone masonry.

The earthen kang is used by the northerners

Rectangular platform made of adobe or du brick for sleeping with zhi. The mat is spread above, and there is a hole dao below, which communicates with the chimney inside, and can be heated by a fire.

Method: On the ground, it is necessary to use soil, sand, etc. to raise to half of the height of the kang, and then use bricks to build a flue in the shape of "self", which is called the kang hole as the saying goes. You can also build the flue first and then fill it with soil, which is stronger and the kang surface is not easy to sink.

The width of the kang hole does not exceed the length of a brick, generally the length of the brick is 2 3, the height is about the height of the brick (depending on the height of the kang), and the horizontal brick is built in the same direction. If the kang is very large, generally one or two kang holes should be left in the kang hole to leave one or two deep pits, that is, after the soil at the bottom of the kang is taken out, and then reinforced with bricks, so that it is convenient to open the kang surface and dig out the ash after the ash is more. The interface with the chimney must also be there.

Then use bricks to cover the kang surface horizontally, and smooth it with sand and mud. Remember, the kang hole must be wiped with yellow mud, not mixed with anything else; To wipe the kang noodles, you must use yellow sand mixed with a small amount of yellow mud, with a ratio of about 8:1.

If you find cracks when you burn the kang noodles, it means that there is more yellow mud and you need to wipe it again. In order to look good, the side of the kang can be plastered with a layer of sand ash (white ash + sand).

Rural homes will burn the kang in winter, the kang is a good measure to keep warm, but the kang also has a certain structure and construction method, if you want to make the kang out of the kang good to burn and keep warm, today we will talk about the rural kang insulation plate method?

First of all, we have to lay out the basic structure, and then put some materials in the kang, refractory materials, such as some stones or other refractory materials on the market.

Then we cover the top blank, in the gap of the billet we use special thin mud to smooth it, after getting these, cover the kang surface with thermal insulation soil, thermal insulation soil can be used to replace it.

If you feel that the kang is too fast, you can add insulation soil or sand to the kang surface, and if it is slow to heat, reduce the insulation soil or sand.

When making the stove door, we can use iron sheets to do it, which can block the circulation of air inside the stove, so that the heat of the kang will not go out of the chimney quickly.

The soil kang needs to have a certain thermal insulation capacity, and it is an earth and stone structure, it needs to be stable, the soil kang is a rectangular platform made of adobe or brick for sleeping in the north, the mat is spread above, there is a hole below, and the chimney communicates, you can burn the fire for heating, and the specific operation steps of the production are as follows:

1. Use red bricks on the ground to build a supporting column base.

2. Build a smoke guide groove at the chimney mouth of the wall.

3. Lay a refractory insulation layer in the kang.

4. Splice the prefabricated kang board on the column base.

5. Smooth the kang surface with cement and fine sand mud.

6. Burn straw and other kang surfaces in the stove to dry.

7. Spread the kang leather to sleep people.

The fire kang is mainly popular in ancient China in the Northwest Plateau, the Central Plains, the middle and lower reaches of the Yellow River, North China, Northeast China and other northern regions, and the cooking fire is used as a cold heating system (system) sleeping facility with heat energy. In this issue, I will take you to learn more about the structure of the soil kang masonry method, and how to build the rural soil kang to burn the relevant content.

Structural diagram of the soil kang masonry method.

1. The structure of the rural fire kang must be set up in a desperate plan, and everyone must already know that the kang should be burned well, first according to the design drawing, but the last procedure should be retained, and the billet should not be covered.

2. At this time, some stones (or other refractory materials, such as broken pottery pieces and messy land, porcelain pieces, and broken bricks) should be put into the kang hole, and the kang head should be put more and less at the end of the kang to form a slope. The tail of the kang can be placed below 25 cm from the surface of the kang. But you have to be careful to put the stone on the honeycomb, not strictly, so that the heat will pass through the stone crevices, and the soot will fall through the stone crevices.

3. Then cover the top blank, pay attention to the kang tail should be high, the kang head should be low, and the kang surface is also a slope. Billet gap sludge smoothing. Next, the insulation soil is on the kang surface, if there is no suitable insulation soil, it can also be replaced with sand. The head of the insulated soil kang is thick, and the tail of the kang is thin.

4. After that, it is time to burn the kang and test the results of labor. If the kang heats too fast, add insulation soil to the kang surface, and if it heats too slowly, reduce the insulation soil (or sand). Finally, it is shaped according to your heating situation.

Replacing the insulation soil with sand is defective, and sand pits will appear after a long time, so use cement covering or other methods after shaping.

5. There are generally large stoves in rural areas, and the stove is open after burning a fire in winter or burning coal. Make a stove door with an iron sheet and block the door to prevent air circulation. Then the heat in the kang will not go out of the chimney quickly, although it is not strict, but it is quite effective.

If only the stove is burned, or if there is no heat in the stove, use a large plastic bag filled with useless plastic or other materials to block the stove door.

6. According to this method, it is not only comfortable, but also can save fuel and reduce environmental pollution.

How to build a rural earthen kang to burn.

1. Pave the bottom of the adobe along the direction of the kang, lean against the wall on the left and right, the flue between the rows, the distance is the width of the adobe, and the blocks are tightly clamped. This flue should be aimed at the entrance of the flue and gable chimney that communicates with the stove.

2. Two billets are erected on each billet at the bottom of the floor (called piles in the jargon), and a billet is a beam on the flat frame on the two columns. One bottom, two columns, and one beam constitute a mouthpiece. Four billets can be counted as one unit, so that several units fill the kang hole.

The adobe is vertically tiled along the beam and the kang as the surface, and the blocks should be tightened.

3. After the kang noodles are paved, smooth them with grass and mud. The actual operation method is to accompany the letter column and frame the beam while paving. After the kang noodles are smeared, immediately burn the kang in the stove until the kang noodles are dried to avoid the grass mud from wetting and breaking.

The structure diagram of the soil kang masonry method, how to build the rural soil kang to burn the relevant content, will be introduced here for you. The kang is mainly composed of three parts, mainly including the stove of the heat source, the fire kang for heating and heat dissipation, and the chimney for discharging the smoke.
