Furnace Completion

The top part of the furnace was completed in one day because the height of the furnace was changed to 20 meters and the dwarves did the hardest part, the powdering of the magic stone.

In reality, the furnace would have been completed in half a day, but it took a day because Habel and his team made unusually detailed adjustments.

However, the finished furnace was beautifully finished because of the attention to detail. It was perfectly symmetrical, with smooth curves from the bottom to the top and a perfect circular cross-section inside the furnace.

"...It's perfect!"

"Yes, excellent!"

Habel and the others said this with crossed arms after checking every inch of the furnace. Apparently, they were satisfied with the results.

When they finally seemed satisfied, they immediately started talking about the Wind Pumping box.

"There are eight wind vents in the bottom, four in the middle, and four in the top. We'll open and close them depending on the condition of the furnace."

"You should leave all the lower ones open"

"If we blow too much air, it may cool it down, but the lower part, which is hotter, will be fine. We'll always blow air so that the wind vents don't get blocked."

"How many Wind Pump boxes should we make? Should we make at least four?"

"That's right. If we make four, we can run two of them and four of them at the same time.

The Dwarven furnace is said to have a human-powered air blower to burn the inside of the furnace. In Japan, they would have called it Fuigo.

The Dwarf Wind Pump box is a device that uses the increase or decrease in air volume to blow air through an airtight container with intake and exhaust valves.

The Wind Pump box was well thought out, with two separate rooms in the middle of the box that could be alternately filled with air. The box was also weighted so that one person could continue to blow air as long as he or she was strong enough to do so.

But it was still hard work. Looking at the newly drawn blueprints and listening to Habel's explanation, I wondered if it could be done any better.

The automatic power generation is electric power, wind power, and hydroelectric power. The Seat Village has a constant flow of water from the river. So, I thought, why not use water power?

"...I think I'll modify it a little bit."

I muttered, and Habel and the others raised their eyebrows and tilted their heads.

"hah?"

"What are you talking about?"

Habel and the others were stunned. No, half of them were looking at me like I was a fool.

I had to get serious or I might lose my good name as a lord.

I decided to make a trap using water drawn from the river. I used a waterwheel to move the two Fuigos alternately. Instead of increasing or decreasing the volume of air by stepping on them, the walls are moved from left to right to increase or decrease the volume of air to blow air.

By making the structure similar to the pedals of a foot-powered boat, air can be pumped into the furnace by the force of water.

When we actually built it, Habel and the others rolled their eyes and kept quiet. For now, we left Habel and the others, who were not moving, to build the piping to the wind tunnel. We built a sealed box to collect the wind supplied by the waterwheel, and installed a valve that could be opened and closed manually. Beyond that, there are several pipes coming out and extending around the furnace.

"Where do you want to make a wind tunnel?"

I turned around and asked Habel and the others that, and I saw them cross their arms and look dumbfounded.

"...That's really insane, isn't it?"

"I can't get enough of it."

"I wish I had that magic."

Mumbling, the dwarves said something, but Habel punched himself in the face before calling out.

"Hey! Now we need to build a furnace! Let's figure out where to put the windpipe!"

Habel said, and for some reason the dwarves all punched themselves in the face and crowded toward the furnace.

"The bottom and the top are good on all sides."

"Or we can shift the middle wind vent."

"Yes. That way the wind will get in all the way."

"Hey, put a mark on the wall of the furnace."

The dwarves draw black circles on the walls of the furnace, noisily discussing.

"Okay, that's about right."

Habel said, looking up at the furnace when it was somewhat finished. The dwarves nodded in agreement.

"Yeah, that's not bad."

"This is good."

They were very noisy. I wondered if they meant it was a good job.

Thinking about this, I made something like an iron straw.

"So, do I just install a wind vent like this?"

When I asked the question for confirmation, the color of the dwarves' eyes changed.

"No, no!"

"Don't cut the end of the wind vent at a right angle! It will clog up in no time!"

"It's better to make it narrower in the middle and widen the tip on purpose. It prevents backflow.

"The end will melt and be replaced in six months anyway. The steel and stone will melt too."

Hearing this conversation, I somehow thought it would be a good idea to protect the area around the wind vent, so I modified it.

This time, I made a larger straw and hardened around it the same material as the walls of the furnace.

"Oh? You're doing something interesting. But that's not good enough. If the metal part melts, it will clog the vent."

"I see. Oh, then why don't we make it out of the same material as the furnace walls?"

The dwarves snorted with difficulty when I asked that.

"We tried that, of course, but after a long time of use, it would slowly crumble. If it's metal, it will melt and escape through the outlet, but if part of the furnace wall collapses, it won't melt, so it will get stuck. Then the furnace has to be shut down and the fire extinguished. If that happens, we can't use the furnace for at least two months."

With a sigh, the dwarf replied.

Once the fire is extinguished, the furnace is cooled down, and then we go inside to clean and repair the inside of the furnace. The wind vent will also have to be rebuilt. The fire will take a lot of time.

But it would be a hassle to shut down the furnace and rebuild the wind vent every six months.

"I'm going to have to rebuild the exhaust vents. Then, let's do some experiments on what material to use on the vent, so we don't have to rebuild it."

When I muttered this, Habel and the others immediately responded.

"What?"

"It can't be that easy."

"How many hundreds of years do you think the Dwarves have been studying this?"

Hearing their skeptical glances and words, I smile wryly.

"I can do experiments that even the Dwarf Nation couldn't do, you know."

As I said this, Habel and the others froze for a moment and then gasped.
