The principle and structure of the Northeast Fire Kang 10

The principle of the kang is to use the hot air generated by the combustion of fuels such as straw and branches to dissipate heat to the adobe when it passes through the flue of the fire, and the adobe is a poor conductor of heat, so the temperature of the kang will last after it is heated. The kang is composed of three parts: the stove, the kang body and the chimney. The stove with the kang can be cooked, and the kang body can be used for heating, and it can also be used to sit and lie down.

The chimney is a masonry kang exhaust flue. The kang body has straight hole type, horizontal hole type, flower hole type, etc.

The ondol is a kind of masonry structure with a width of about 1.7 to 2.3 meters. Inside it is a brick wall with a flue in the wall between the kang. The kang has a stove and a smoke mouth, the stove is used to burn firewood, and the smoke and heat produced by burning wood pass through the wall between the kang to heat the stone slab above to generate heat, so that the kang produces heat.

Finally, the smoke is discharged from the ondol smoke mouth through the chimney.

The kang is composed of three parts: the stove, the kang body and the chimney.

The stove with the kang can be cooked, and the kang body can be used for heating, and it can also be used to sit and lie down.

Due to the different regions and ethnic habits, the plane layout of the fire kang is also different, there are the south kang, the north kang, the Shunshan kang, the 10,000-character kang (curved ruler) and the concave kang of the ring room.

The chimney is a masonry kang exhaust flue.

The kang body has straight hole type, horizontal hole type, flower hole type, etc.

These forms can be categorized into two types: parallel and series, the former with uniform heat dissipation and poor exhaust, and the latter the opposite.

A few key knowledge points: 1. The kang is built on the cement floor, which does not reflect moisture and is easy to burn. 2. The kang hole is wide and deep, the flue gas resistance is small, and there is a lot of ash, and there is no need to pick up the kang once in a few years.

3. The brick wall that forms the flue is thicker, which can play the role of storing heat and transferring heat evenly. 4. The position where the smoke in the stove enters the kang hole is called the throat eye. The size of the cross-section of this place must be less than the sum of the actual air inlet area of the stove door and the grate, and it must also be smaller than the area of the chimney mouth.

In this way, a small local lot is formed, and the furnace can have pumping force. You can try to install a soft water pipe on your own faucet, and suddenly pinch the pipe head in the process of running water, the outlet becomes smaller, and the water flow becomes stronger, which can impact the sediment. This is the principle of increasing the local pumping force.

This force can carry the smoke up. 5. The bottom surface of the chimney root should be more than one foot lower than the bottom surface of the kang hole. To put it bluntly, there is a pit.

This is the legendary kennel and the wind cave. Its function is to prevent cold air and rainwater falling from the mouth of the chimney from flowing directly into the kang hole. It is best to add a small cement pipe to the mouth of the chimney in winter, it does not matter whether it is tall or short, and some people in the countryside will buckle an open-bottomed basin.

This will allow less cold air to come down from the mouth of the chimney. Don't forget to like it.

The principle and structure of the Northeast ondol are not well understood, and there are no actual restaurants.

The principle and structure of the ondol is that the ondol is a kind of brick and stone structure with a width of about 1.7 to 2.3 meters and a length that can be determined by the length of the living room. Inside it is built with bricks between the kang wall, there is a flue in the kang wall, which is covered with a relatively flat stone slab, the stone slab is covered with mud and smoothed, and the kang mat can be used after the mud is dried. The fire kang, also referred to as kang, or big kang, is a common heating equipment in the northern living room, and the northeasterners also introduced it into the palace.

The role of the ondolThere are many fire kang in the Shengjing Imperial Palace, and there are several shops in one room, which not only solves the problem of sitting and sleeping. It can also dissipate heat through so many kang surfaces and maintain a high indoor temperature. For example, in the Guan Ju Palace in the East Chamber, there are seven shops in the first palace of Kang noodles, Lin Toe, Yanqing, and Yongfu.

The same is true in the palaces. Moreover, not only in the palace rooms, but even the two gates of the Chongzheng Palace, which were used as the rest and accommodation of the watchmen, were also paved with fire kang and fire ground, which shows that the fire kang was laid in the palace.

Ondol is a traditional heating method that uses two basic physical phenomena: burning heat and heat conduction. The main part of the kang is that there is a fixed brazier above the flue, whenever the night falls on the potato, only need to put the firewood in and light it, and then move it out, leaving the smoldered red iron charcoal there, this peiwan will emit wisps of green smoke the next day. The smoke takes away a lot of heat and warms the whole house.

The structure of the fire kang is mostly made of adobe, the kang is placed on the side of the window of the living room, the stove is generally built in the hall house, and the stove is connected with the gable wall of the kang partition.
