How to build a kiln and burn charcoal?

1. Open a small vent hole at the bottom of the charcoal burning place (charcoal kiln). Be careful not to damage other places, and ensure that the sealing performance of the charcoal burning kiln is not affected.

2. Keep the air at the bottom of the charcoal kiln unobstructed. Different charcoal kilns can use different methods. Some of them use bricks as ventilation ducts at the bottom, while others dig ditches.

3. Fill the whole charcoal kiln with prepared firewood or sticks. This kiln installation is very particular.

4. Ignite the charcoal raw materials (logs or sticks) in the charcoal kiln and keep burning.

5. Seal after burning in the kiln. Pay attention to leave a smoke outlet with a diameter of about 10 cm, which can be connected with smoke treatment measures to treat the smoke generated during charcoal burning.

6. Earth kilns, commonly known as cave dwellings, are a form of residential buildings, mainly distributed in the Loess Plateau, and are characteristic buildings in Shanxi and Shaanxi provinces.

7. Because of the lack of building materials such as wood and stone and the fuel needed for burning bricks and tiles in the Loess Plateau, Shaanxi has a layer of loess with fine texture and dense caves. Cave dwellings, especially earth kilns, make full use of this situation. The outer soil layer is conducive to indoor constant temperature and sound insulation. This is the floor of the ground, which can bear a great load. There are not many combustible materials, so the fire is not easy to spread.
