After punching the hole, Armand cut the bottom of the cup directly, so that the ventilation and slag leakage effect at the bottom is stronger, and there is no need to fan the fire, and the air passing through itself is enough.

Next, he picked up the medium-caliber cup, opened a 16CM hole at the bottom of the shell, tentatively put the inner tank in, and then tried to install and take it out, and nodded to Qin Shiou after feeling that it was okay, Qin Shiou also nodded to him, as for what he was nodding, then he didn't know.

The 20 cm diameter cup is naturally used to make the shell, and the handle of this cup, Armand deliberately did not take it off, he can hold the handle and hold the cup, and said: "You see, it will be safer when you transfer the stove in the future, isn't it?" ”

Qin Shiou asked hesitantly: "I want to know, the temperature of the furnace is so high, won't it burn the protective plastic on the outside of the handle?" And if the plastic is not protected, then the heat is transferred when the stove is used, and the temperature of the handle is so high, who would dare 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 was skeptical about this and said, "But didn't you say that the flame temperature produced by the combustion of wood gas is more than that of natural gas and various liquefied gases?" That's high enough temperature to burn the handle. ”

Armand looked at him and said, "Did you know that my students can pass their final exams? ”

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

Armand shook his head and said, "No, that's because they won't fight with me. Whatever I say is what it is! ”

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

There's nothing to argue about. This furnace is just Armand teaching Qin Shiou how to do it, in fact, the stainless steel iron sheet is not strong enough, the temperature generated by the combustion of wood gas, burning it ten times will destroy this furnace, and he will use titanium alloy iron sheet to remake it after he learns it.

The 18 cm cup should also be made around the perimeter and at the bottom, as it will serve as the hearth of the stove and will mainly play the role of pulling out the fire. Ventilation must be adequate.

Probably after the production, Armand worked on the details, and it was these details. As a result, the value of the final product is not the same.

The two of them worked for more than two hours, and a shiny wood stove was made, the small stove was bright silver, and the curves had the smoothness of a large water cup. Armand held the handle and lifted the glass. Said proudly: "Well, is this a work of art?" ”

Qin Shiou exclaimed: "You French people are really powerful, you can make a stove into a work of art." ”

Of course, this is a greater compliment, but in fact, it is the shape of a cup, what is the sense of art?

Armand was praised by him, but he was energetic, he put the cup in front of Qin Shiou, and said, "Look, how deceptive this thing is? Later your friends will come as guests. You can light the firewood first, then bring it to him and say treat him to a hot cup of tea. When he opens the lid, what do you think will happen? ”

Qin Shiou looked at the handsome French guy dumbfounded, and the latter smiled with satisfaction: "Aren't you surprised?" ”

No, it's a fool, you think you have too many friends, Qin Daguan complained silently in his heart.

After the wood stove was made, the next step was to test the burning, Armand put firewood in it, and then poured some alcohol to ignite it, after igniting the firewood flame was not big at first, but the more it burned, the more momentum it burned.

Obviously there is no pressurized equipment, this thing can make the flame whine outward, which shows how fast the wood gas rises and how strong the heat release ability is.

The cold water of a military lunch box only took four minutes to boil, Armand took the lunch box, and then asked Qin Shiou to look at the firewood inside: "It's only burned less than half, isn't it?" The remaining firewood is enough for you to make another soup to drink. ”

Later, Armand also gave Qin Shiou an experiment, he put a box of water again, and then stuffed the stove with damp firewood and even branches that had just been broken off the tree, and although the fire had decreased slightly, it was still burning!

This is one of the biggest advantages of the wood stove, which does not require much raw materials, as long as it starts to burn.

Finally, when the flame was extinguished, Armand poured out the ashes that remained in the cup, completely reduced to ashes, and said: "Is it very sufficient?" Look, it's so low-carbon and environmentally friendly, and it's so much better with this kind of furnace than a gasifier, isn't it? ”

Qin Shiou nodded yes, then pointed to the stove and said, "It's more like a work of art now, uncle, you are too powerful." ”

Armand grinned awkwardly, the wood stove was prone to black ash, and only two jugs of water had been boiled, and the silver color of the previous stove shell quickly turned black, like a famous abstract painting.

But in any case, Qin Shiou participated in the production of a wood stove, of course, his role in it was to hand a wrench, a screwdriver, a cutter, etc., but the value is that he successfully learned how to make a wood stove, and he could make it himself in the future.

Got the wood stove, Qin Shiou proudly went to show everyone, Qin's father and Qin's mother suddenly hated him when they saw this scene, and pulled him and said: "You are all a father, why are you still so childish?" Why do you make this little stove? Is it the one that a dad should play? ”

Winnie hurriedly said good things to her husband: "Mom and Dad, this stove made by Xiaoou is not a toy, it is very powerful, we don't need to bring fuel when we go up the mountain in the future, with this stove, everything on the mountain can be used as fuel except for stones and water." ”

Father Qin sighed and said, "You see, if you say the same thing, Winnie will say it differently. ”

Qin's mother also said: "Winnie is much more mature than Xiaoou, and Xiaoou is blessed, find such a good daughter-in-law." ”

Qin Shiou couldn't cry or laugh, so I treated me as a child with a DIY stove? This is a typical Chinese parental thinking, this kind of stove is originally a thing for adults to play in foreign countries.

However, he is a filial son, and he will not argue with his parents, mainly because he understands that he can't win when it comes to arguing, because Qin's father and Qin's mother's thinking is not in the same dimension as him.

Qin's father and Qin's mother became more and more energetic, and Winnie took the opportunity to perform a little inside, which made the two old men more satisfied with her, and began to praise Winnie instead.

After praising for a while and waiting for Winnie to leave, Father Qin pulled him and said, "It's almost time to come here to rest, it's time to talk about business, the date of your engagement and marriage with Winnie has to be set, do Canadians have anything to say?" ”

Qin Shiou said: "You have to negotiate with Winnie's parents from now on, you can discuss, Winnie and I can do it any day." ”

Mother Qin glanced at him and said, "Pure nonsense, engagement and marriage are big days, how can they be set casually?" (To be continued......)
