Steel Dynasty - Chapter 823

[Chapter 822 Improvement of Steam Engine Efficiency]

Xiao Ming closed the folding book Niu Ben sent, with a heavy smile on his face.

Qian Dafu on the side then laughed, “The emperor is so happy, it must be that the remaining three cities have been captured.

” “You guessed it right, now all Guandong is under the control of the Great Chongqing Kingdom, and now the Great Chongqing Kingdom It is equivalent to gaining three more houses of land, which is really gratifying. “Xiao Ming said.

The three northeastern provinces are well-known grain production bases in modern times. The fertile black soil makes the grain output here very high.

It is a pity that the Central Plains dynasties rarely set their sights here, so that in various dynasties this place has been occupied by foreign races. Occupied.

Now that he has recaptured the entire Guandong, his next step is to establish an industrial zone with Anshan as the core and turn it into a food production base. There will also be a large shipyard in the contemporary Liaoning area where Beisha City is located.

“Such a great achievement .

, The emperor will definitely leave his name in history and be praised forever, and the old slave can also benefit from following the emperor. “Qian Dafu smiled even more happily.

Xiao Ming shook his head helplessly: “I don’t care what historians think, I just hope that the country of Chongqing will no longer suffer foreign bullying and stand on top of the world. “

Having said that, Xiao Ming remembered something and picked up his pen.

Now that Guandong has been stabilized, there is no need for so many troops to be stationed outside. He wants to recall most of the musketeers.

The barbarians have moved westward and are now homeless dogs. They are unable to invade the country of Chongqing anymore. , now he can finally free up his hands to completely unify the Great Yu Kingdom.

After all, King Yong, King Huainan, King Chu, and King Ruyang are still there. Strictly speaking, the Great Yu Kingdom is still in a state of division.

He can only stabilize the country. Only then could he concentrate on using more advanced firearms than the Europeans to end the colonial era in the West.

After writing an edict to recall the army, Xiao Ming asked Qian Dafu to send the eunuchs to Jinzhou

and rest for a while, so that he would have time to clean up. The remaining vassal kings

explained the matter, and Xiao Ming did not sit idle, but went to Qingzhou University under the protection of the guards. Now the daily lectures at the Emperor’s Academy have become almost as big an event as the imperial meeting

. , has the honor of being a disciple of the Emperor, and the learning atmosphere of Qingzhou University is now strong. There

are almost no students wandering around here. Every student you see is walking in a hurry with books, because not only the Emperor Academy, but also Qingzhou University pursues the selection process. The system also puts a lot of pressure on students.

If they don’t study hard and fail the exam, they will be expelled after failing two re-examinations and lose their qualifications as students at Qingzhou University.

This is the case for many poor students .

It was intolerable, because everything at Qingzhou University was free, and they couldn’t find a better place. According to past practice, when Xiao Ming arrived at Qingzhou University,

he

first answered some difficult questions at the Tianzi Academy.

He went to the laboratory where key experiments were currently being conducted.

Different from the past, he was now directly involved in various experiments as a technical consultant, and he formulated a set of scientific technologies to be developed successively to integrate the technologies in the technological crystals. Realize it step by step.

“Your Majesty, this is the latest improved triple-expansion steam engine. Generally speaking, it has completely surpassed the previous single-cylinder reciprocating engine. “

Xiao Ming is now in Lin Wentao’s laboratory. After repeated improvement experiments, Lin Wentao has finally manufactured a triple-expansion steam engine.

In fact, the principle of this steam engine is similar to that of a simple reciprocating engine, except that this steam engine has three cylinders.

This The three cylinders are the middle, middle and low cylinders. The steam engine performs three-stage expansion in the three cylinders, thereby improving the thermal energy efficiency of the steam engine.

Therefore, the real advancement of the triple-expansion steam engine lies in the three-stage utilization of the steam engine, which means that the steam enters the steam engine. After the first cylinder does work, it will go to the second cylinder to do work, and then the third one. In this way, the same amount of steam engine can make the steam engine do more work.

In this way, using equal amounts of coal and water .

, this kind of steam engine can allow steam ships to sail farther on the sea.

To put it simply, this is equivalent to the fuel consumption of modern cars. The fuel utilization rate will determine how far the car can run under the same conditions

. In his era, sea replenishment was already very difficult. Being able to reduce fuel replenishment points would be a huge savings.

Being able to produce a single-cylinder reciprocating steam engine, the accessories of this three-cylinder steam engine are naturally not a problem. After all, it is used. The materials are the same.

The only thing that needs to be worried about is the explosion problem caused by excessive pressure in high-temperature and high-pressure steam engines. There are many examples of this in history.

The reason why it took so long to successfully develop this kind of steam engine is to test it. Material strength, and the use of safety valves in steam engines.

However, Dayu State already has a barometer. After properly discharging the steam pressure with the safety valve, the high-temperature and high-pressure steam engine is now much more stable.

Because of this, Lin Wentao announced the third expansion. The steam engine was successfully developed.

“After all, your hard work has not been in vain, but you can’t be idle now. You must produce this steam engine immediately and deliver it to the shipyard. Zhang Liang is waiting for your steam engine to transform the warship. “Xiao Ming looked at the steam engine in the laboratory with great satisfaction.

This is almost the same as the triple-expansion steam engine in the science and technology library. After possessing basic industrial capabilities, many mechanical manufacturing has become easier. Only qualified accessories are needed, and some machinery can be successfully operated. After it was manufactured, the only thing that needed to be strengthened was the strength and precision of the accessories.

Lin Wentao was relieved when he heard that the three-expansion steam engine was finally qualified. Ever since Xiao Ming stared at the laboratory, everyone was tense because of this. Achieving the goal one day earlier.

Although the pressure was greater than before, Lin Wentao was still very happy. Not everyone could get the honor of studying steam engines with the emperor.

Now every time I meet with officials, they no longer have a slight tone of contempt. On the contrary, they are extremely envious.

“Yes, Your Majesty, I will arrange for craftsmen to make a triple-expansion steam engine when I get back. However, what is the task of the research room below?” Lin Wentao looked forward to it. Those of them who are studying technology can’t be idle.

Xiao Ming hesitated for a moment. In fact, for him, the triple-expansion steam engine was just the beginning. This steam engine was just the simplest multi-expansion steam engine.

Lin Wentao still needs to go a long way in the field of steam engines, and the next step forward for multi-expansion steam engines is steam turbines. However, Xiao Ming does not expect this to be realized within five or six years.

Because this is completely the technology of the contemporary World War I, but although it cannot be realized, advance technical reserves are still necessary.

So he said; “Continue to develop and improve multi-expansion steam engines. If you still have the energy, you can consider steam turbines. This is a revolutionary power machine for both ships and electricity.”

Lin Wentao in the book I have also been exposed to the concept of steam turbines, but this kind of thing is obviously much more complicated than a steam engine, and Qingzhou’s current industrial capacity cannot produce it.

However, thinking that Su Liangcai’s electricity research was making good progress, he had a faint expectation in his heart.
