On the fourth day of the second month of the ninth year of Tianwu, on the "Holy Day", Zhu Cixuan accepted the congratulations of the ministers in Fengtian Hall and held a banquet in the palace.

Today is the birthday of Emperor Zhu Cilang of the Ming Dynasty. As a minister, everyone naturally has to express their opinions.

Some people gave calligraphy and paintings, some gave treasures, and some gave all kinds of strange things, and said a copy with instructions.

All in all, it all makes sense!

The most surprising thing is that the Royal Academy of Sciences actually sent a train!

After hearing this, Zhu Cilang stopped eating and took the Minister of Civil and Military Affairs to the location of the Royal Academy of Sciences outside the East City.

The steam engine is the research project he attaches most importance to, which is related to the future social development of the Ming Dynasty. Whether it is the development of social economy or the improvement of military strength, it is a qualitative leap!

In recent times, if the steam engine can be used in social production as soon as possible, it will greatly improve the current production efficiency.

In the memorial, Sun Heding, President of the Huangming Academy of Sciences, called the train a steam locomotive. Some officials did not understand and thought that this thing was steaming buns or steaming rice? Need the emperor to come in person?

The Department of Machinery of the Huangming Academy of Sciences, this is a factory with a vast area of ​​land, which houses a large number of tools and semi-finished mechanical equipment, including siphons, crane drinks, light pots, farming, rotation mills, bicycles, etc.

These are mainly used in agricultural production and are basically masterpieces of the old academician Wang Zheng.

Walking in, everyone heard a noise.

Zhu Cilang looked at the sound and saw several steam engines running in the distance. Two people were responsible for shoveling carbon to make a fire, and hot water was placed next to it.

Steam continues to emerge with the up and down movement of the piston, driving the rotor to rotate, making a "squeak" sound from time to time.

On the two small steam engines, two spinning wheels were connected to each of them, and the spinning wheels were rotating "gululu".

The large steam engine is connected to a deep well and is constantly turning around to pump water.

Some steam engines are connected to huge stone mills.

The Royal Academy of Sciences has been working on the steam engine project for nearly ten years since its establishment.

The first steam engine has actually been developed in Tianwu for three years, and Zhu Cixuan also visited to watch and guide him.

However, the size of the first generation steam engine is very small. The larger one is more than one person tall, while the smaller one is only breast-length, and the power is very low, which has no practical value at all.

At that time, looking at the emperor's disappointed eyes, many academicians of the Huangming Academy of Sciences began to increase their horsepower and devote themselves to the steam engine research and development project.

Now six years have passed, and hard work pays off. With the support of strong manpower, material resources and funds, the Huangming Academy of Sciences, which has gathered experts, has continuously improved the steam engine and finally made significant progress!

The power of the first generation of steam engines is about one or two horsepower, which can only drive a weight of more than ten kilograms. It is better to smash them directly if they can pull the train!

Now the steam engine reported by the Royal Academy of Sciences can carry people and be used as a vehicle, you can imagine how big the improvement is.

Soon, everyone walked out of the factory and came to an empty test site. Zhu Ciyang finally saw the world's first train!

Its shape is similar to the original train, and it is described in one word: petite!

Seeing the thing making a thunderous sound and thick white smoke emitting thick rolling white smoke, Xu Sheng hurried to the near the steam engine and watched carefully. Regardless of the heat, he reached out to touch it to see if this guy was in danger.

The officials were also curious, not knowing what magical effect this thing has.

On the other hand, Zhu Cixuan was listening to Sun Heding introducing the development and improvement process of the steam engine.

The world's first steam engine was developed by Wang Zheng, an academician of the Ministry of Machinery of the Royal Academy of Sciences of the Ming Dynasty, in the third year of Tianwu.

Wang Zheng was called "King of Southern Xu and Northern" together with Xu Guangqi, and had a profound scientific attainment.

However, the old academician is obsessed with the research of agricultural machinery, with the purpose of "benefiting people's livelihood and daily use", and is good at using agricultural machinery to help ordinary villagers save time and effort, and is not very interested in the research and development of steam engines.

Whenever farming in spring and summer, the villagers drive the machinery developed by Wang Zheng to benefit from agricultural labor, and are all happy.

People in the village called Wang Zheng "Kong Ming's Rebirth", while some women called him "friend of women and the pillar of family".

Moreover, Wang Zheng was nearly 80 years old at that time and was in poor health, so the improvement of the steam engine was completed by others.

In the fifth year of Tianwu, Wang Zheng took a leave of absence for half a year due to his physical condition, and the research and development of the steam engine was taken over by Bo Jue, an academician of the Ministry of Machinery. (The one who invented the Phoenix brand bicycle and artillery mirror)

When he first developed the first generation of steam engines, Bo Jue participated. He was very familiar with the principles of the structure of the steam engine and discovered two major shortcomings of the steam engine.

The piston movement is not only slow, but also discontinuous. If this happens in sexual intercourse, it can be called upset and stuttering, which can help flirt.

But this is mechanical, so the problem is big!

This disadvantage makes the steam engine less utilizing and wastes raw materials very much.

When the raw material cost is greater than the commodity cost, this production-assisted steam engine will inevitably lose its value and will not be popularized.

After that, Bo Jue began to think about ways to improve it, until he suddenly thought during a walk that since Wang Zheng's steam engine is low in thermal efficiency due to the condensation of steam in the cylinder, why not let the steam condense outside the cylinder?

Since then, Bo Jue has developed the initial idea of ​​using a separation condenser...

In the sixth year of Tianwu, Bo Jue designed a steam engine with a separation condenser. In theory, the thermal efficiency of the new steam engine will be three times that of the first generation steam engine!

However, theory is theory, and it takes a long way to go to turn the steam engine on the drawing into a really usable steam engine.

In the next two years, Bo Jue worked hard to build several steam engines, but the effect was not as good as the first steam engine, because the separator might not easily leak air everywhere and could not be activated.

If it is personal research, the huge capital cost spent during the period will definitely make Bo Jue overwhelmed and may even give up on research.

However, the Royal Academy of Sciences of the Ming Dynasty not only has strong financial support from the royal family, but also has a wide range of materials and craftsmanship configurations, as well as a large number of personnel to be mobilized, but also has many scientific elites to discuss and learn.

Bo Jue was not a fight, and soon, the first steam engine with a condenser was successfully tested!

Compared with the first generation of Wang Zheng steam engine, the second generation of Bojue steam engine has significantly improved thermal efficiency and can meet a large number of mechanical kinetic energy. It is called the first steam engine with practical value.
