Chapter 369: Building a Earthen Kang (3)

"I won't go into detail about this process. Anyone who has made a stone bed at home should know how to do it. The main thing is to ensure stability." Xia Tian once again emphasized the importance of stability and began to explain the next step.

"Now the lower part is used for burning firewood. In order to keep it as warm as possible, prevent heat loss, and prevent sparks from jumping out, the next thing we need to do is to seal up the surrounding areas." Xia Tian took out a few smaller stone slabs, placed them next to the stone bed and the ground, and filled the gaps around them, leaving only two small openings.

"Everyone must pay attention to the fact that apart from leaving these two small openings, all other parts must be properly fitted. If there are any areas that are not fitted properly, you can use mud to fill the gaps. Otherwise, when the fire starts, toxic and harmful gases will escape through these gaps."

Building an earthen kang is definitely not difficult, but it is not easy either.

Every step must be done carefully, and the handling of details is very important, which will directly affect the final product effect, that is, the experience of everyone sleeping on it every day.

Once all the gaps are filled, you can proceed to the next step.

At this time, Xia Tian was not anxious. Instead, she pointed at the two empty seats and started interacting with everyone. "Now I want to ask everyone, why did you leave these two empty seats?"

In fact, this is not a difficult question. It’s just that this is the first time for everyone to encounter this, and they were listening carefully in the lecture just now, so when she asked this question, they really couldn’t answer it right away.

Everyone looked at each other without saying a word, and finally cast their eyes on Si Ye.

This means that we expect him to answer on everyone's behalf.

"This..." Si Ye changed from a half-squatting position to a standing position, walked half a circle around the semi-finished product made by Xia Tian, ​​pondered for a moment, and expressed his guess.

"Since this is a bed that's heated by a fire, there's a fire underneath. One opening should be for adding firewood. As for the other opening... I guess it's for ventilating the room."

The principle of the earthen kang is similar to that of the stove, except for the shape and purpose. Both are used for heating, with firewood added at one end and ventilation at the other.

Si Ye had renovated the stove with Xia Tian before, and he had learned this method of using fire at that time, so he naturally made the association this time.

But he didn't expect that the temperature of the flame was so high. It was of course perfect for cooking, but it could also be used to heat while sleeping. This was indeed an extremely clever idea.

"You're right, this is the function of these two openings." Xia Tian agreed and praised Si Ye's words, and continued to explain the points to pay attention to.

"Considering that everyone has this earthen kang in their own cave, you can prepare a small stone block for the firewood storage area and plug it when you don't need to add firewood, so as to ensure warmth to the greatest extent.

As for the ventilation hole on the other side, you need to adjust it according to the situation of your cave. You must ensure ventilation, otherwise people will suffocate to death inside."

After saying this, Xia Tian paused for a while to give everyone some time to digest the information and understand it for themselves. Any questions could be communicated and resolved on the spot.
