Chapter 393 Charcoal kiln, blast system!

Carry a bamboo basket on your back.

Come to the river.

Lu Yu quickly found the borrowing point when he built the earth kiln last time.

Because it just rained a few days ago.

The soil layer has loosened a lot.

Just for a while.

Just deducted a bag full.

"Copper smelting requires charcoal. In addition to temperature, there is another important reason-"

After finishing the straps, Lu Yu carried the bamboo basket full of clay on his back.

Step through the muddy clay layer in one fell swoop.

Walk and say:

"That is, charcoal can act as a reducing agent."

"It does a good job of reducing the copper in the copper oxide."

"And this is the key to copper smelting by fire."

"This method has existed since ancient times, and until today, there are still many professional smelters who choose high-quality charcoal for their operations. The reason is this."

"Charcoal is essential if you want to separate out the copper in the mineral powder."

"In this way, how to obtain better quality charcoal has become the first thing we should consider now."

Speaking of which.

Lu Yu pretended to pat the bamboo basket behind him mysteriously, and gestured to everyone:

"These clays can help us."

"With it, we can try to build a reusable charcoal kiln for burning charcoal, and with a charcoal kiln, this problem will naturally be solved."

Most of the people in front of the screen had never heard of these primitive technologies that Lu Yu talked about.

While curious.

Everyone also listened in a fog, and kept asking questions in the barrage.

See the water friends so enthusiastic.

Lu Yu smiled and explained:

"It may sound complicated, but it's actually very simple. Don't worry, it will be clear later."

...

All the way back to camp.

Lu Yu put down the clay.

Go directly to the storage room.

Take a lot of firewood and put it next to the earth kiln.

Then, he chose an open space about the size of the earthen kiln and started planning.

"It's right here."

"The first step in making a kiln is to stack the firewood into a cone."

Talk and do.

It only took less than five minutes.

He initially piled the firewood prepared in advance into a slender pyramid shape.

"Eucalyptus branches are a very good source of charcoal, as long as you do it right, the charcoal will be perfect, hard and durable."

"Of course, it is also possible to use ordinary tree branches, but the effect will definitely be greatly reduced."

After the wood pile has an initial large size.

Next, just follow this shape and add firewood in circles.

this work.

It seems quite simple.

But in fact, it is very important.

Make sure that the firewood retains enough clearance without being too loose.

Because of the stacking of wooden piles.

It will directly affect the success of firing.

If the gap is too large.

The branches are difficult to fully burn, and the yield will be greatly reduced.

And too loose, too full of burning, is not acceptable.

In order not to affect the yield, it took Lu Yu more than half an hour to complete the process of stacking the wooden piles.

The pile of wood is about one meter high.

The area is almost two square meters.

The bottom end is round.

From a distance, it looks a bit like a fire pit.

But it is more exquisite than the ordinary fire.

The branches are next to each other.

Very neat.

"Okay, almost there..."

"With the wooden piles, the next thing to do is to use clay to surround them in circles and make them into a kiln shape."

"It should be noted that the mud layer should not be too thick, about the size of the palm of your hand, and try to keep it in the range of one centimeter to two centimeters."

Clay by the creek.

Humidity is just right.

It can be used directly without secondary processing.

Saved a lot of things.

If the clay is dry, that's a lot of work.

Just the part of the mud is enough to torture people.

After a few more simple chats, Lu Yu got busy again.

Drag the bamboo basket beside him.

Take out the clay.

Along the edge of the pile, build up in circles and circles.

Just like building a kiln.

There's not much to say about the whole process.

After a while, when it was about to seal, Lu Yu spoke again:

"The top of the charcoal kiln needs to leave an opening and cannot be completely sealed."

"The size of the opening depends on the size of the wooden pile. There is no established standard, so you can grasp it yourself."

to here.

The prototype of the entire charcoal kiln is ready.

From a distance, it looks like a small dirt bag.

It is interesting.

However, this is not the end.

A complete charcoal kiln also needs to open vents at the bottom and plan the "door line".

The vent is to facilitate the observation of the burning speed of the charcoal and to block it in time.

And the door line.

It is so that after the charcoal is burned, the kiln wall can be easily lifted and the charcoal can be taken out.

These two details are equally important.

Especially the vents on the chassis, it is absolutely impossible to not have it.

...

At the bottom of the charcoal kiln, after deducting four vents.

Lu Yu took out the stone knife again and drew an arched arc on the outside of the kiln wall.

"Feather God, what is this for?"

"Ghost knows!"

"Fairy magic?"

"Do you recognize this formation?"

Glancing at the barrage, Lu Yu shook his head and explained:

"Brothers, this is the door line."

"After the charcoal is fired, the kiln walls become very hard."

"If you want to not destroy the kiln itself, it is also a technical job to take out the charcoal."

"So, the door line has a place to use it."

"At that time, as long as you gently scrape it with your hands, the kiln wall will collapse along the outline of the door line, which is very convenient. The most important thing is that it will not affect the subsequent use of the earth kiln."

When the audience heard it, they suddenly realized that Lu Yu was a clever little ghost!

"6666!"

"show!"

"Prepare for a rainy day!"

"It makes my scalp tingle!"

...

After the charcoal kiln is complete.

Lu Yu took the kindling from the fire and put it in the opening above.

Wood piles wrapped in charcoal kilns were lit.

Holding the kiln wall.

Lu Yu blew up the flame while holding back the thick smoke, winked and said:

"When the time comes, the fire will burn down through the opening."

"Opposite the direction of the updraft."

"After a period of burning, the firewood in the kiln is converted into charcoal as the fire moves from above to the bottom."

soon.

By the time the fire had fully spread, the fire above the wood pile was getting bigger and bigger.

Seeing this, Lu Yu went on to explain:

"The flame above the wood pile is a volatile gas. CO and H2 are burning. If you can see these gases, it means that the temperature in the kiln is changing. This is a normal phenomenon."

With that said, he controlled the drone again and let it fly to the vent at the bottom of the charcoal kiln.

"There is nothing to pay special attention to in the whole firing process, but one thing to pay attention to is that every once in a while, you must observe the vents. If you can see the flames at the vents, you must use them immediately. The clay blocks all air inlets, including the opening at the top of the kiln, and when the temperature cools down completely, the charcoal is ready to burn."

"666666!"

"Shit, the anchor is so professional!"

"Brother steady!"

"I'm very curious, where did Yushen learn this strange knowledge?"

"interesting!"

"The ash fertilizer will turn black and give it to the anchor aircraft × 1! - It's amazing!"

"Invincible Zhong Er, the Demon King of Ghosts and Animals, gave the anchor an energy drink × 1! ——666, it's too bad!"

...

Thank you all for the gifts.

Lu Yu took a breath and wiped the sweat on his forehead:

"Firing charcoal is very time-consuming, at least five or six hours even if everything goes well."

"We have to make good use of this time. Brothers, let's show you something fun, Come on!"

Nani?

fun stuff?

After listening to Lu Yu's words, the audience instantly became energized and kept posting barrages:

"What's the situation? Fun stuff?"

"Shampoo upside down, or is it a daily five-speed electric fan?"

"The whole job?"

"Anchor, please start your irritating performance!"

...

talking room.

Lu Yu pulled out a eucalyptus tree over one meter long from the firewood in the storage room.

Then go back to the campfire again and sit on the ground.

He put the eucalyptus branch in his hand and looked at it carefully.

then.

He decisively took out the stone knife, peeled off the bark, and fanned it to the bonfire.

"By stirring up the bark, the temperature of the campfire can be raised..."

Before Lu Yu could finish speaking, the audience in the live broadcast room became noisy.

I feel like I've been tricked by Yushen...

"That's it?"

"Anchor, this is not fun at all..."

"To fan the flames?"

"Do something?"

"Brothers, I think things may not be so simple."

...

Lu Yu didn't pay attention to the barrage.

While stirring up the bark, he continued:

"That's the principle of the blower."

"Using this principle, we can instantly increase the temperature of the fire several grades!"

After saying that, Lu Yu cut the bark in two with a stone knife.

It becomes two rectangles about twenty centimeters long and five centimeters wide.

then.

He also cut a 2.5 cm gap in the middle of the rectangular bark and inserted the two gaps together.

At this time.

The bark becomes a cross fan blade!

After showing it a little to the camera.

Lu Yu grabbed a small straight wooden stick.

With a stone knife at the top of the wooden stick, a cross-shaped opening was cut, and the fan blade was fixed on it.

Tighten with rope.

In this way, a cross-shaped simple fan is ready.

Next, he put the fan in front of him.

Hold the stick with both hands.

use it as the axis.

Use the method of drilling wood to make fire by rubbing the stick back and forth.

In contrast, the wind of the fan is much more than the bark.

With the rotation of the fan, the charcoal fire in front of him turned red and then dark.

The temperature has also risen a lot.

At this time, Lu Yu finally opened his mouth:

"This is the original blower."

"The principle is very simple, but it is very practical."

"It is precisely because of this thing that primitive people really learned to 'play with fire' and mastered the technology of smelting metal tools."

The live broadcast was here, and the audience suddenly realized that they finally understood what Lu Yu meant.

It turns out that this guy is going to build a blower!

"Anchor, you're so awesome!"

"thief 6!"

"A powerful character like Yushen, if he travels back to the primitive era, he can be conferred a god in minutes!"

"Fuck, I have to watch and study hard, in case I can use 233333 in case of crossing"

"Brother, just be soft with your sister-in-law, why bother!"

"Hahahahahaha, I laughed so hard that I rolled off the bed!"

"If Feather God has been living here for ten years, even a gun can be made?"

"Be confident and remove the bar!"

...

Set the cross fan blades aside.

Lu Yu took some clay from the bamboo basket and threw it on the stone slab in front of him.

First knead it into a round mud cake.

Then, take the mud and knead it into several mud sticks.

round and round.

Carefully round the edge of the mud cake.

When he finally closed his mouth, he also deliberately left a long "air outlet".

it looks.

Live like a gourd.

The only difference is that the bottom of this thing is flat compared to the scoop.

"This thing that looks similar to a chamber pot is the casing of the blower."

"Of course, this is just a prototype. Next, we need to enrich the details-"

"666, is the night pot okay?"

"This is a tasteful live broadcast!"

"Feather God: Next, I will show you how to use this chamber pot!"

"Yes, it does have that smell!"

"I have a bold idea!"

"A bit like Peppa Pig!"

"What kind of night pot, it's actually a shit button!"

"Fuck, brother, stop talking, I'm eating!"

...

Looking at the strange barrage, Lu Yu said with a wry smile:

"Brothers, can you stop talking about such a tasteful topic... I almost believed it."

Just finished speaking.

In the live broadcast room, there was another burst of laughter.

It took a long time to close this topic.

Subsequently.

Lu Yu used another part of the mud to enrich the outer wall of the fan.

Make it more rounded.

then.

In order to facilitate the entry and exit of the drill pipe, a round hole slightly smaller than the palm of the hand needs to be dug out at the bottom of the mud cake.

The role of the blower is to fan the flames and increase the firepower.

Therefore, the air outlet also needs to pay more attention to concentrate the wind.

So, in the end, Lu Yu made another big announcement.

Extend the spout a few centimeters.

Made into a funnel-shaped cylindrical shape.

"Well...if the conditions allow, it is best to bake it, which will be more durable. If you don't have that condition, you can use it directly, but before using it, it is best to dry it by the fire."

After that, Lu Yu took the fan blade he had made before and put it in the fan casing.

And turn the casing upside down.

At this time, the drill rod on the fan blade can just pass through the round hole at the bottom.

As long as the drill rod is twisted, the wind generated by the fan blades can be blown out along the pot mouth of the fan.

And then to heat up the fireworks!

In order to prove the feasibility of the wind turbine, Lu Yu held the drill pipe tightly and gave a general demonstration to the audience.

"Hoohoo-hoo-!"

result.

Unsurprisingly.

With the rotation of the fan blades in the fan, the flame of the bonfire burns more and more vigorously.

Whoosh!

Very rhythmic!
