Chapter 826: Improved steam engine performance

Xiao Ming closed the bellows sent by Niu Ben, with a thick smile on his face.
Qian Dafu on the side laughed, "The emperor is so happy, presumably the remaining three cities have been conquered.
"You guessed it right, now Guandong is all under the control of Dayu State, and now Dayu State is equal to three more land, which is really gratifying." Xiao Ming said.
The three northeastern provinces are well-known grain production bases in modern times, and the fertile black land allows high grain production here.
It's just a pity that the Central Plains dynasty rarely set its sights on here, so that it has been occupied by foreign races in various dynasties.
Now that he has retaken the entire Guandong, the next step is to build an industrial zone with Anshan as the core, and at the same time turn it into a food production base, and there will be a large shipyard in contemporary Liaoning where Pesha City is located.
"Such a great feat, the emperor will definitely stay in the history, praise it forever, and the old slaves will be able to follow the emperor." Qian Dafu smiled happily.
Xiao Ming shook his head helplessly: "I don't care what historians say. I only hope that the country of Da Yu will no longer be bullied by foreigners and stand on top of the world."
After that, Xiao Ming remembered something and picked up his pen.
Now that Kanto is stable, there is no need for so many troops to be stationed outside. He wants to recall most of the Musketeers.
The barbarian moved westward, and now he is a dog of the mourning family, unable to harass the Great Yu country any more, and now he can finally free up his hands to completely unify the Great Yu country.
After all, King Yong, King Huainan, King Chu, and King Ruyang are still there. Strictly speaking, Great Yu is still in a state of division.
Only when the country is stabilized can he concentrate on using firearms more advanced than Europeans to end the colonial era in the West.
After writing an edict to recall the army, Xiao Ming asked Qian Dafu to send an to Jinzhou.
Once the army returns to the court and rests for a period of time, he will have time to clean up the remaining vassals.
After confessing the matter, Xiao Ming did not sit idle, but went to Qingzhou University under the protection of the guards. Now the daily teaching of the Tianzi Academy has almost become a major event equivalent to the court meeting.
In order to be able to enter the emperor academy and have the honor of being a student of the emperor, the learning atmosphere of Qingzhou University is now strong, and there are almost no students hanging out here.
Every student I saw was walking in a hurry with books, because not only the Tianzi Academy, but the selection system pursued by Qingzhou University also put a lot of pressure on the students.
If you don’t study hard and you fail the exam, you will be dismissed after failing twice in the make-up exam, and you will lose the qualifications of Qingzhou University students.
For many poor students, this kind of thing is intolerable, because Qingzhou University is free, and they cannot find a better place.
According to past practice, Xiao Ming first answered some difficult questions in the Tianzi Academy when he arrived at Qingzhou University.
Then he went to the laboratory that is currently conducting key experiments.
Different from the past, he is now directly involved in various experiments as a technical consultant, and he has formulated a set of science and technology to be developed successively to realize the technology in the technology spar step by step.
"My lord, this is the latest and improved three-expansion steam engine, and overall it has completely surpassed the previous single-cylinder reciprocating engine."
Xiao Ming is now in Lin Wentao's laboratory. After repeated improvements and experiments, Lin Wentao has finally built a three-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.
The three cylinders are respectively high, medium 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-time utilization of the steam engine. In other words, after the steam enters the first cylinder to do work, it will enter the second cylinder to do work, and then the third. In this way, the same amount of steam engine can be used. Let the steam engine do more work.
In this way, using the same amount of coal and water, this steam engine can make the steam ship sail farther at sea.
To put it simply, this is equivalent to the fuel consumption problem of a modern car. The fuel utilization rate will determine how far this car can run under the same conditions.
In his era, maritime replenishment was a very difficult task. It would be a huge saving to reduce fuel replenishment points.
A single-cylinder reciprocating steam engine can be manufactured. The accessories of this three-cylinder steam engine are naturally not a problem. After all, the materials used are the same.
The only thing to worry about is the explosion of high-temperature and high-pressure steam engines due to excessive pressure. There are many such examples in history.
So the reason why it took so long to develop successfully is to experiment with the material strength required by this steam engine and the use of safety valves on the steam engine.
However, Da Yu country already has a barometer. After cooperating with the safety valve to properly discharge the steam pressure, the high temperature and high pressure steam engine is now much more stable.
Because of this, Lin Wentao announced the successful development of the three-expansion steam engine.
"It's not a waste of work for such a long time, but now you can't be idle. You must immediately produce this kind of steam engine and deliver it to the shipyard. Zhang Liang can wait for your steam engine to transform the warship." Xiao Ming looked at the steam engine in the laboratory. satisfaction.
This is almost the same as the three-expansion steam engine in the science and technology library. After having basic industrial capabilities, many machinery manufacturing becomes easier. Only qualified accessories are needed. Some machinery can be successfully manufactured. The only thing that needs to be strengthened is the accessories Strength and precision.
Lin Wentao breathed a sigh of relief when he heard the words. The three-expansion steam engine was finally qualified. Since Xiao Ming stared at the laboratory, everyone has tightened their nerves in order to complete the goal as soon as possible.
Although the pressure is greater than before, Lin Wentao is still very happy, and the honor of studying steam engines with the emperor is not something that everyone can get.
Now every time they meet with officials, they no longer have a slight tone of contempt, on the contrary they are extremely envious.
"Yes, the emperor, the next official will arrange for the craftsman to manufacture the three-expansion steam engine~EbookFREE.me~ But, what is the task of the next research room?" Lin Wentao looked forward to them, and they couldn't take it easy.
Xiao Ming hesitated for a moment. In fact, the three-expansion steam engine was just the beginning for him. This steam engine was just the simplest multi-expansion steam engine.
In the field of steam engines, Lin Wentao still needs to go a lot, and the multi-expansion steam engine is a steam turbine, but Xiao Ming does not expect it to be realized in five or six years.
Because this is completely contemporary technology during World War I, although it cannot be achieved, advance technical reserves are still necessary.
So he said: "Continue to develop and improve the multi-expansion steam engine. If you still have energy, you can consider the steam turbine. This is a revolutionary power machine for both ships and electricity."
Lin Wentao has also touched on the concept of steam turbines in his books, but this kind of thing is obviously much more complicated than steam engines, and Qingzhou’s industrial capacity cannot be produced at present.
However, thinking that Su Liangcai's power research is progressing well, he has a faint expectation in his heart.
