Chapter 81 Explode a Boiler
A rain, at the end of May, washed away the green leaves in the mountains and forests, and the birds flapped their wings and flew high into the sky in the fresh air.
Under the rainbow, the one-ton boiler temporarily escaped the shackles of gravity with a loud noise.
With a loud "bang", the boiler flew over the hill for more than 200 meters and landed in a mountain stream. The rabbits who were drinking water in the distance were startled and fled in all directions.
On the hilltop one kilometer away, a group of soldiers divided into two groups, one going to the place where the boiler was first fired, and the other to the place where the boiler was dropped.
Frederick frowned and was speechless towards these guys.
He just mentioned that he was worried that the boiler would explode due to excessive pressure, and then the group started destructive tests. Ogilvy also made several special pressure gauges.
These pressure gauges are connected to the boiler through long pipes. The pointer on the dial moves with the pressure, and at the same time, a toothpick drives the pointer on the opposite dial.
When the pressure of the boiler disappears or the boiler is blown up together with the pressure gauge, the pointer on the second dial can stay at the maximum pressure position of the boiler.
The fifth boiler is being blown up now, and it is planned to blow up 5 more boilers to obtain enough data.
The boiler fried this time is a finished product after design and positioning. The design length is 2.5m, the outer diameter is 1.2m, and the wall thickness is 12mm. It uses slightly strengthened elemental steel and weighs about 1.1 tons. After adding an appropriate amount of water, it weighs about 3.3 tons. .
Today the boiler only needs to be equipped with instruments, heating magic array and control system to be used, but the air outlet and safety valve are blocked.
"My heart is bleeding." Frederick sighed and said, "These are all gold coins!"
Omett on the side smiled, it was worth the money anyway. It’s not my own money, but I’m still smiling happily.
Frederick continued: "Well, in the future, a steam engine will cost almost a thousand florins to build. Who can afford it?"
Ogilvy and others estimated the cost of the steam engine, and the price frightened Frederick.
This means that nobles below the baron can no longer expect to buy steam engines.
"It doesn't matter." All Might is knowledgeable. "Others can't use it, so why can't our Lord Paladin use it?"
"Your large glass plate is flat. It's so smooth that even the king sent someone to buy it."
Frederick curled his lips and made a cheap "Holy Book" himself, and donated the maltose formula, which was given by the Light Church. I got a paladin title and an enchanted saber, and then nothing more.
Omet saw his expression and asked curiously: "Are you dissatisfied with the Church of Light?"
Frederick did not deny it.
A strange smile appeared on All Might's face.
"What's the matter?" Frederick was a little surprised to see him smiling like this, "Is there anything I don't know?"
Ogilvy replied with a smile: "Wait until you are an adult. You’ll know.”
Then he changed the subject: "The church is quite rich. How about letting them buy the tractors you mentioned and rent them to farmers?"
"Not very good." Frederick shook his head. Shaking his head, "There are still many farms with strip fields. The tractor plows two families' land at once, and the field ridges in the middle are gone. How to calculate it?"
"The landowners may rent their common land. It’s a big piece, so it’s quite convenient to use.”
“If we really want to promote tractors, the land needs to be redistributed between landlords and tenant farmers, at least so that the land becomes one piece like in my territory. "
"When we arrive, the fields in a village may only be divided into four or five plots according to crop rotation. "
"Others can't afford the steam engine, so we will use it internally."
"How long do you estimate it will take to complete all the work after the boiler experiment is successful?"
Omet made a mental calculation. , said: "It will take another month to produce the first machine."
"If we want to mass-produce it, I think it will be next year."
Frederick thought about it Thinking about it, he asked: "Is the current steel production enough?" Ogilvy is now equivalent to the director of the Industrial Bureau of Wesenland, and is very familiar with this matter. He replied: "The smelter will be able to officially produce next month, and it has been reserved. With sufficient raw materials and fuel, skilled workers are already in place, and apprentice workers are learning while working.”
"The construction workers building the smelting plant are now starting to move to Langnar City in the south to build a cement plant there according to your plan."
Frederick nodded slightly, Then he said: "At present, steam engines are of great use in machine production. Now we can start planning to replace other power sources. In the future, the obsolete magic reciprocators can be sold to the village."
Ogilvy & Mather I was a little depressed, thinking that my magic reciprocator could make more money, but I didn't expect that a more powerful steam engine would appear.
He replied: "The replacement of the two machines is not a big problem. They are essentially reciprocating motions, and there are very few things that need to be changed."
Frederick suddenly said: "The steam engine is ready, we should start to enter the textile industry."
"You arrange for people to find the best weavers in the territory, and in the autumn everyone will discuss how to turn the steam engine into a new one." Used in spinning and weaving.”
Omet immediately agreed.
Frederick took a deep breath of fresh air on the top of the mountain to relax a little.
As the stalls spread out, more and more things happened.
The Edelweiss Library he had told the Grand Duke of Mainz before, the Grand Duke took the initiative to help find a master architect, who is now studying the layout of the Pentagon.
The first phase of the army's recruitment has ended, and now the new recruits are undergoing physical training and traditional pike formation training. He hasn't had to go and see it yet.
Wait.
Frederick and Omet chatted about things in the territory for a long time, and the student team led by Schmidt came over to report after sorting out today's experimental data.
"Principal, Professor Ogilvy," Schmidt said, holding a piece of paper, "the results are out."
Ogilvy was quite satisfied with Schmidt. When he saw someone making money, he didn't ask the principal for advice. Instead, he looked for work on his own. He was discovered by the principal at a paper mill, and finally got a knighthood by using a double-sided printing machine. As promised, the work of the steam engine was handed over to him.
After Frederick nodded, Schmidt looked at the data on the paper and said: "When the boiler exploded today, the internal pressure reached about 25 atmospheres. Judging from the status of the boiler and the scene, it was the screws of the top plate. It couldn't withstand the pressure and collapsed."
"The power of the explosion was huge. The surrounding wooden piles were blown away, chickens and ducks were killed, and the flying roof broke a fox and a tree. "
Frederick nodded and said thoughtfully: "The normal working pressure of this boiler is 12 atmospheres, and the maximum pressure is 15 atmospheres. The safety margin of 10 atmospheres is enough. "
“Remember to take the boiler back and melt it again. I don’t have that much money to make new materials.”
Schmidt had a big smile on his face, as long as he didn't have to pay for it.
Frederick glared at him fiercely, and then asked: "How is the steam engine doing?"
Schmidt's face suddenly darkened, and he cautiously Said: "There is still a gap between the sealing ring on the cylinder and the piston. When doing the water filling test, it was found that water would leak."
Frederick thought that there was nothing that could be done about it, so he said: "It's just a leak." Just let it go and keep it within an acceptable range.”
“Let’s solve the problem first and then solve it.”
Schmidt breathed a sigh of relief and said: "Principal, I have two ideas."
"Can a safety valve be controlled by a spring? If it is the current one, it will be fine if it is flat. If it is tilted, its working pressure will be reduced. "
"The second is the accessories on the boiler. Can their safety strength be set between the working pressure of the safety valve and the boiler's ultimate pressure to act as a second step? The safety valve is also an early warning before the explosion."
Frederick thought for a moment and said, "You can control these yourself. The next step is up to you. I am very optimistic about you."
There is only so much he can take out. The rest is for these scholars to continue research and develop in research.
Schmidt immediately shouted happily: "Thank you, principal, for your cultivation!"
