Internal masonry diagram of rural fire resistance kang
Step 1: Kang in rural areas is better to burn. First, the kang must be laid according to the design drawings, but the last working procedure should be reserved and the billet should not be covered.
Step 2: put some stones or other refractory materials in the hole of the kang, put more kang at the end of the kang and less at the end of the kang. Put the kang below 25 cm from the kang surface. Put the stone in the honeycomb, so that hot air will pass through the gap and soot will fall from the gap.
Step 3: Then cover the upper blank, with the tail of the kang higher than the kang head, and wipe the gap of the square blank with mud, and then fill the kang surface with insulation soil, which can be replaced by sand. The insulation kang has a thick tail and a thin tail.
Step 4: Finally, burn the kang. If the temperature of the kang rises quickly, add more insulation soil on the kang surface, and if the temperature rises slowly, reduce the insulation soil.

1. Usually, on the ground, you need to use soil, sand, etc. It should be padded to half the height of the kang, and then a zigzag flue should be built with bricks. As the saying goes, it is called Kangdong. You can also build a flue first, and then fill it, which is stronger and the kang surface is not easy to sink.
2. The width of the kang hole is not more than the length of a brick, generally 2/3 of the length of the brick, and the height is about 4 or 5 bricks (depending on the height of the kang). Bricks are laid in the right direction. If the kang is very large, one or two deep pits should be left at the head of the kiln at regular intervals, that is, after the soil at the bottom of the kang is pulled out, it is reinforced with bricks, which is convenient to open the kang surface and dig out the ash after too much dust. In dialect, it is called the ash falling room.
3. There must also be an interface with the chimney. Then fill bricks horizontally on the kang surface and smooth them with sand and mud. Remember, you must wipe the kang hole with yellow mud, and you can't mix anything else; The kang surface must be plastered with yellow sand mixed with a small amount of yellow mud, and the ratio is about 8: 1.
4. If cracks are found on the plastered kang surface after burning, there is too much yellow mud and it needs to be plastered again. The kang can be covered with sand ash (white ash+sand) to look good.
The internal masonry diagram of the rural fire resistance kang and the schematic diagram of how to build the northeast fire resistance kang will take you here. In the north of China, the stove mouth of ordinary kang is connected with the stove, so that the kang can be heated by cooking with firewood without burning it separately.
