Chapter 618 Homemade Gas Lamp
The stones that had been kicked over rolled into the middle of the firepit, and the ashes left after the fire inside were blown up one after another.
Seeing Lu Lu's strange behavior, several people immediately surrounded him.
Suhebalu looked puzzled, completely unable to understand what Lu Lu was doing.
Because of what happened just now, vent your anger on the stove?
So, after being slightly startled, he quickly apologized: "I'm sorry, it's the first time I've seen the situation just now, and I've lived most of my life. The wolves I've seen in the past are usually three or five, and more than 20 wolves come out at once like this. In the past, I just heard that we panicked just now and didn’t do things well.”
Lu Lu looked up at Suhebalu, and shook his head slightly: "I don't mean to blame you, in the situation just now, even if the flashlight is well illuminated, it's just three or two more wolves, don't think too much about it." .”
"What is this for?" Zhang Shaofeng asked strangely.
"I want to try and see if I can get something brighter to illuminate!"
As Lu Lu said, he stretched out his hand and began to search among the stones in the stone stove.
"What does brighter things have to do with this?" Liang Kangbo couldn't help asking.
Lu Lu shook his head slightly: "I'm not too sure, try it! You all go back and guard against those wolves, in case of a sudden attack...Brother Suhebalu stays here and does me a favor."
Hearing this, Zhang Shaofeng and others returned to the fire with their guns in hand, and looked at the green light spots in the darkness in the distance, which were wandering wolves.
These wolves are scattered and scattered around the yurt in a semicircle.
"Are they planning to surround us?" Chen Xiuqing glanced around: "Or, are they trying to bypass us?"
"It looks like they want to surround us!" Zhao Yongke took a deep breath.
When he said this, he turned his head to look at Lu Lu who was still searching with a flashlight.
Lu Lu quickly picked out a few stones and asked Suhebalu to light them with a flashlight. He held a stone in one hand and collided with each other. The burned black stone was smashed to pieces.
This is limestone, which is used to pile up stone stoves to cook things. It is easy to get quicklime under the fierce stove fire, and this is what Lu Lu is looking for.
He deliberately chose a piece and put it in the snow. As soon as it encountered snow, the lime reacted immediately, and the temperature rose rapidly, scalding the snow and water vapor.
Not to mention the principle, many people have seen this situation.
When building houses in these years, there is no cement. Many people just buy quicklime and add water to make flour, and then mix it with sand to increase the viscosity.
Quicklime is also often used to make lime water and process some ingredients.
In later generations, the self-heating pot is the most familiar to everyone. It can cook food with heat, thanks to the quicklime inside.
But few people know that when limestone and charcoal are mixed and burned together, as long as the temperature is up, something similar to quicklime will be produced-calcium carbide, which is the so-called calcium carbide.
That is, the coal stone lamp used for lighting at home or in the mine, and its fuel is this thing.
The reason why Lu Lu is not sure is because this is a simple stone stove built for cooking meat outside. If it is burned with wood, the temperature will not reach the temperature, and it is difficult to produce calcium carbide. If it is burned with coal, it is very likely. , because the required calcination temperature can be achieved.
And he was lucky because he saw coking coal and coal here in Suhebalu.
So while picking it up, Lu Lu asked by the way: "Brother Suhebalu, have you ever used coking coal in your earthen stove?"
"The two sons in the family are ignorant, and they always think coal is convenient. They always secretly use coking coal to cook things to save trouble. After the things are burned, people don't need to keep looking at them." Suhe Baru sighed: "It's okay. , I know people who burn coking coal around the coal mines, and every winter, they can always pull some."
Hearing this, Lu Lu felt confident again. He quickly picked out a few gray and black stones, and took out the stainless steel wine bottle in his pocket.
Everyone in Lu Lu carried this kind of stainless steel wine bottle on their backs. They bought it for carrying wine up the mountain. There is a burning knife inside. When it is very cold, open it and take a sip, then close the lid and take it with you. It can be put in the pocket - the pocket flagon, or something from the old Maozi.
He poured out the last sip of wine in it, then placed the selected stones on a stone, smashed them with the back of a hunting knife a few times, picked up a few pieces and put them in the wine bottle.
Then, he took out a flavonoid cartridge case from his pocket, held the tip of the hunting knife and spun it against the buttocks of the cartridge case, a small hole was quickly drilled out, and then he grabbed some snow from the snow and stuffed it in. The bullet case plugged the mouth of the wine bottle, and it fit perfectly.
Then, he took out a match, rubbed it on the skin of the match and ignited it, and when it reached the small hole in the bullet casing, the gas that came out was immediately ignited, forming a white flame.
Zhang Shaofeng and others watched this miraculous scene.
Suhebaru was also dumbfounded, he couldn't understand why Lu Lu could make a fire with just a few pieces of "quicklime" and some snow, and it was so bright.
This scene is also amazing!
Calcium carbide is an extremely unstable thing, and the gas produced after it reacts with water is acetylene, which is made of gas lamps.
The reason why Lu Lu can use this thing is because of watching videos.
At the beginning, he was always fooled, saying that using quicklime and water can ignite the emitted gas, which aroused his interest, and he spent two yuan to buy a catty of quicklime, and he put it in a glass bottle and tried it. After a long time, the fire that can make wool, the explosion is powerful.
It wasn't until later that I found out that calcium carbide was actually used.
It is a mixture of limestone and coking coal in a certain proportion, and is calcined at a high temperature of [-] degrees in an electric furnace. The reason why it is named calcium carbide has nothing to do with electricity. It is purely crushed because it is calcined in an electric furnace.
This stone stove is almost always used by Suhebalu's family to cook things, and it seems that it has been used for a long time.
It is wrapped with unreacted calcium carbide, which makes Lu Lu feel a little lucky.
But now, the high-brightness coal stone lamp has been made, and what can be sprayed out is a small flame after all, which is far from enough.
Lu Lu immediately disassembled the lamp head of his flashlight, and took off the reflector inside. The cartridge nozzle passed through the hole in the middle of the reflector, and immediately a bright white light shot straight into the sky.
With this brightness, one is worth several flashlights.
This stunned everyone present.
None of those present had ever used coal stone lamps, only kerosene lamps were used for lighting at home, and no one had ever been in a mine.
Moreover, in Lu Lu’s impression, coal-stone lamps were more common around the 90s. At that time, there were quite a lot of people who mined private coal. Although there were miner’s lamps, many people still liked to use coal-stone lamps.
Because, in addition to being bright enough, the burning flame can also detect whether the air in the mine contains enough oxygen. If you see something wrong with the flame, you should run out quickly.
The coalstone lamp in Lu Lu's hand didn't last long before the flame dimmed.
But now Lu Lu is full of confidence.
With the brightness just now, it can illuminate far away, and the range is much wider.
On the other hand, on the pasture, those howling wolves were already very close, and several of them had already appeared under the reflection of the fire, and they could see their appearance.
One by one ran around, wandered around, lowered their heads from time to time, sniffed around, or bared their teeth in this direction.And kept approaching, looking like that, might rush over at any time.
Yuan Bao and the others had already stood in front of them, baring and barking at the wandering wolves.
Lu Lu saw that the wolves were constantly sniffing the blood on the snow, and after almost sniffing, they would bark their teeth at the few people, feeling like they wanted revenge.
I'm afraid things won't go well tonight.
Because the wolves are constantly shrinking the range of the encirclement, they look fierce.
"Quickly, give me two of your wine jugs!" Lu Lv urged.
You have to prepare quickly, otherwise you will rush forward all of a sudden, and the range of greetings is not small. If you are not careful, it is too easy to cause problems.
For those present, no matter who it is, getting a bite is definitely not a good thing.
Hearing this, Zhang Shaofeng and Lei Meng immediately turned around and threw their flagon towards Lu Lu.
Lu Lu prepared it in the same way, loaded calcium carbide, and drilled holes in the bottom of the shell case.
After getting the three coal-stone lamps ready, he said to Sukhbaru, "Go back to the house and get some water."
Snow melts too slowly and produces too little water to react enough.
Sukhbaru was stunned for a moment, and after he realized it, he quickly ran towards the house.
Lu Lu went to the fire, asked for the flashlights of Zhang Shaofeng and Chen Xiuqing, and quickly took off the reflectors.
Those wolves were getting closer and closer, and suddenly, a little far behind, a big majestic wolf slowly walked out, raising its head and letting out a terrifying wolf howl as it walked.
With this howl, the wolves got closer together.
This is the wolf king!
Lu Lu took a deep look at it.
The distance between the nearest wolves and the fire was no more than ten meters. Some bared their teeth and began to press their legs. There were signs that their attack was imminent.
Yuan Bao's barking became louder and louder, and they also had the movement of pressing their legs, and they were also eager to get up, the difference was only a command.
Seeing the critical situation, Lu Lu couldn't help but look back at Suhebalu.
After walking a few steps, I didn't see him back after going for two or three minutes. I couldn't bear to watch him get out of the yurt with a flashlight, but ran to the middle yurt, muttering something to the woman inside.
"You're fast!" Lu Lu urged angrily.
Suhebalu didn't dare to stay any longer, and quickly ran towards Lu Lu with the kettle in hand. At the same moment, the wolf king suddenly let out a deep cry, and immediately two wolves rushed towards the two sides one after another. Running out of the side darkness.
Zhao Yongke and Liang Kangbo, who were guarding on both sides, disconnected their guns, one shot at each, and knocked the two wolves that were rushing to the ground to the ground.
It seemed that they were afraid of the gunshots. When the gunshots sounded, the wolves immediately retreated a little and did not continue to attack.But, just listening to the two wolves who were hit but not killed, the black-mouthed black tiger led by Yuan Bao and the green wolf and leopard led by Bailong rushed out to bite them, screaming for a while Again and again.
And the wolves who heard the two wolves screaming, howled again, and the fierce sound continued.
Suhebalu ran to the front, and before he could speak, Lu Lu snatched the kettle he was carrying: "After three minutes, follow the method I just did, and light it in the fire, each according to the fire. One direction illuminates the whole land for me. Don't point the spewed fire at people..."
The temperature was too high, and the flames that spewed out could burn people.
Thank you book friend Ten Miles of Peach Blossom, for the unique reward!
