Chapter 1177

After drilling, Armand directly cuts the bottom of the cup, so that the ventilation and slag leakage effect at the bottom is relatively strong, there is no need to fan the fire, and the air passed by itself is enough.

Next, he picked up the medium caliber cup, opened a 16cm hole at the bottom of the shell, tried to put the liner in, and then tried to install and take it out. When he felt that there was no problem, he nodded to Qin Shiou, who also nodded to him. As for what he was nodding, he didn't know.

The 20 cm cup is naturally used to make the shell. Armand deliberately didn't take off the handle of the cup. He could hold the handle and lift the cup and said, "you see, it's safer to transfer the stove in the future, isn't it?"

Qin Shiou hesitated and asked, "I wonder if the stove temperature is so high that it won't burn the protective plastic outside the handle? If there is no protective plastic, the stove transfers heat when used, and the temperature of the handle is so high. Who dares to touch it? "

Armand was stunned for a moment, and then he said calmly, "no, the protective layer of the handle is not so easy to burn."

Qin Shiou doubted this and said, "but didn't you say that the flame temperature produced by wood gas combustion should exceed that of natural gas and various liquefied gases? That's high enough to burn the handle. "

Armand looked at him and said, "you know, all my students can pass the final exam."

Qin Shiou didn't understand what he said, so he asked strangely, "why? How did you DIY a wood stove in your final exam? "

Armand shook his head and said, "no, that's because they won't be stubborn with me. What I say is what I say!"

Qin Shiou laughed. If he could, he really wanted to let the tiger and leopard bite this guy.

There's nothing to argue about. Armand only taught Qin Shiou how to do this stove. In fact, the stainless steel sheet is not strong enough. The temperature generated by wood gas combustion will destroy the stove after burning it for more than ten times. He learned to make it again with titanium alloy sheet.

The 18cm cup also needs to be perforated around and at the bottom, because it will be used as the furnace of the furnace, which mainly plays the role of pulling out the fire, and the ventilation must be sufficient.

After it was probably made, Armand processed the details, and it was these details that led to the different value of the final finished product.

The two men worked for more than two hours. A shiny firewood stove was made. The small stove was silver and the curve was smooth with a large water cup. Armand held the handle and raised the cup and said proudly, "what's the matter? Is this a work of art?"

Qin Shiou exclaimed, "you French are really powerful. You can make art by making a stove."

Of course, this is more of a compliment. In fact, it's the shape of a cup. What's the sense of art?

Armand was praised by him. He put the cup in front of Qin Shiou and said, "look, how deceptive this thing is? Later, when your friend comes to be a guest, you can light the firewood first, then bring it to him and ask him to have a cup of hot tea. When he opens the lid, what kind of scene will you say? "

Qin Shiou stared at the handsome French man in amazement. The latter smiled with satisfaction and said, "will you be surprised?"

No, idiot. You make complaints about your friend's too many rhythms.

After the firewood stove is made, the next step is to try to burn it. Armand put firewood in it, and then poured some alcohol to ignite it. After ignition, the firewood flame is not large, but the more it burns, the greater the momentum.

Obviously, there is no pressure equipment. This thing can make the flame whine out. From this, we can see how fast the wood gas rises and how powerful the heat release ability is.

The cold water of a military lunch box boiled in only four minutes. Armand took the lunch box and let Qin Shiou see the firewood inside: "it's less than half burned, isn't it powerful? The remaining firewood is enough for you to cook another soup. "

Armand gave Qin Shiou an experiment later. He put a box of water again, and then stuffed wet firewood into the stove, even the branches just broken from the tree. As a result, although the fire was slightly reduced, it was still burning!

This is one of the biggest advantages of wood stove. It has little requirements for raw materials. Just start burning.

Finally, when the flame went out, Armand poured out the remaining ashes in the cup and completely turned them into plant ash. He said, "is it very full? Look, how low-carbon and environmentally friendly this thing is. It's much better to use this kind of stove than a gasifier, isn't it? "

Qin Shiou nodded and said yes, then pointed to the stove and said, "it's more like a work of art now, brother-in-law, you're too powerful."

Armand grinned awkwardly. The wood stove was prone to black ash, and only two pots of water were burned. Previously, the silver bright color of the stove shell quickly became dark, like a famous painting of the abstract school.

But in any case, Qin Shiou participated in the production of a wood stove. Of course, his role is to pass a wrench, screwdriver, cutting knife and so on. But the valuable thing is that he successfully learned how to make a wood stove, and he can make it himself in the future.

When he got the wood stove, Qin Shiou proudly showed it to everyone. When Qin's father and mother saw this scene, they suddenly hated him. They took him and said, "you're a father. Why are you so childish? Why do you make this small stove? Is that what a father should play? "

Winnie quickly said a good word to her husband: "Mom and Dad, the stove made by Xiaoou is not a toy and has very powerful functions. We don't need to bring fuel up the mountain in the future. With this stove, everything on the mountain can be used as fuel except stone and water."

Father Qin sighed and said, "you see, if it's the same, Winnie will be different."

Qin's mother also said, "Weini is much more mature than Xiaoou. Xiaoou is lucky to find such a good daughter-in-law."

Qin Shiou couldn't cry or laugh. I just DIY a stove and treat me as a child? This is a typical Chinese parental thinking. This kind of stove is what adults play in foreign countries. Is it good.

However, he is a filial son and won't argue with his parents. The main reason is that he understands that he can't win in an argument, because the thinking of Qin father and Qin mother is not in the same dimension with him.

Qin's father and mother complained more and more vigorously. Weini took the opportunity to make a small performance in it, which made the two old people more satisfied with her and began to praise Weini.

After boasting for a while, when Winnie left, Qin's father took him and said, "it's almost time to rest here. It's time to talk about business. You and Winnie have to fix the date of engagement and marriage. What do Canadians say?"

Qin Shiou said, "you have to negotiate with Weini's parents from the next day. You can discuss it. Weini and I can do it any day."

Qin's mother gave him a white look and said, "it's nonsense. Engagement and marriage are big days. How can you decide it casually?"
