Chongzhen Emperor Zhu Youzhen was a little embarrassed by Xu Guangqi's praise, but he didn't say that Xu Guangqi was a sycophant, this is not a sycophant, this is the praise of the scientists of the Ming Dynasty for the scientists of later generations! In fact, the generator ahead of the Ming Dynasty's scientific and technological level is only two hundred years old, if the Ming Dynasty is not forgotten, was ruled by the barbarians, Chongzhen Emperor Zhu Youzhen absolutely believes that China's speed of inventing these things, will not be behind the West!

As long as there is a court that advocates science, the Chinese are very smart!

Because of technical reasons, Chongzhen Emperor Zhu Youzhen used coal-fired generator sets!

Coal-fired power generation units are mechanical equipment that converts the chemical energy of fossil fuels such as coal into electrical energy. It is the conversion of the heat energy generated by the combustion of coal into electricity through the power plant (power plant boilers, steam turbines, generators and their auxiliary devices, etc.). Coal-fired power generation has a long history and is also one of the more important ones.

Coal-fired generator sets are mainly composed of combustion system (with boiler as the core), steam and water system (mainly composed of various pumps, feed water heaters, condensers, pipelines, water cooling walls, etc.), electrical system (mainly steam turbine generators, main transformers, etc.), control systems, etc. The first two produce high-temperature and high-pressure steam; The electrical system realizes the transformation from thermal energy, mechanical energy to electrical energy; The control system ensures the safe, reasonable and economical operation of each system. As a traditional power generation method, coal-fired power generation also has its drawbacks and shortcomings, such as the continuous growth of acid gases such as SO2 and NOX emitted by direct combustion of coal, which increases the amount of acid rain in China, and dust pollution has a negative impact on people's lives and the growth of plants. Therefore, it is necessary to continuously improve the stroke of coal-fired power generation, use various technologies to improve power generation efficiency, and reduce environmental pollution. For example, the smoke and dust are treated with desulfurization and dust removal or natural gas is burned. The gas turbine was cooled by air instead.

Daming has no shortage of resources. And these resources have not been developed, Chongzhen Emperor Zhu Youzhen took a big advantage, in his computer, the world's resources have been developed, and the resources in use are clearly marked, he doesn't even need to explore, this year, just the Gyeonggi area. Dig into the ground casually, it's all treasures, treasures of nature!

Chongzhen Emperor Zhu Youzhen and Xu Guangqi talked about the generator for a long time, and taught Xu Guangqi some maintenance, the basic knowledge of use, Xu Guangqi's ability to accept is very strong, write them down one by one.

"My goal is to be able to develop Daming's own internal combustion engine within three years! As long as you can develop an internal combustion engine, you will be able to meet the technical standards for the reproduction of these engines. This is called an industrial hen, and you can use the machine to go to life! There are more and more high-tech equipment in Daming. Science and technology are becoming more and more developed, whether it is military or civilian, it will develop rapidly! "Chongzhen Emperor Zhu Youzhen pointed to the gasoline engine he brought back from modern times, but unfortunately he can't make anything with this machine, he wants to make cars, wants to make airplanes, but this gasoline engine is too delicate and too heavy!

On the one hand, he has no technical replication for the time being, and on the other hand, it is not easy to come by, and there are too many things to ship from modern times, and it is impossible to always ship these finished products! In that case, the cost performance is too low!

Xu Guangqi looked at the gasoline engine curiously, "This thing has such a big effect?" ”

Chongzhen Emperor Zhu Youzhen nodded, "The steam engine I taught you to make is amazing, right?" As the smelting technology matures, your steam engine will become more and more powerful! Using the steam engine on the large battleship I mentioned earlier will make the battleship run ten times faster than a normal wooden ship! But with this internal combustion engine, it will be fifty times faster! ”

Xu Guangqi was shocked, Xu Guangqi understands military affairs, and in war, speed is a qiē! Jiannu is powerful, because the iron cavalry is faster than the infantry, and in naval battles, whoever has the fastest ship has already won half of it! You can beat someone, but no one can beat you, there's no way to lose!

Moreover, as far as the current situation of the Ming Dynasty is concerned, the development of the sea frontier is more important than anything else! There are natural disasters everywhere, and then accompanied by man-made disasters, even if the grain of the Ming Dynasty is reused with high-yield crops, the key is that there is no one to plant the land, and there is no land for people to plant, we must strengthen foreign trade, buy food from outside, in order to tide over the difficulties! Turn the current crisis around!

"This thing is called, the internal combustion engine, which is more powerful than the steam engine that the emperor taught the old minister to control before Zuò?" Xu Guangqi touched it with awe.

Chongzhen Emperor Zhu Youzhen nodded, "The principle is similar to the generator I just told you, the gasoline engine drives the generator to operate, converting the energy of gasoline into electricity. In the cylinder of the gasoline engine, the mixture is violently burned, and the volume expands rapidly, pushing the piston down to work. Whether it is a diesel generator or a gasoline generator, each cylinder works in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. The brushless synchronous alternator is coaxially installed with the crankshaft of the power engine, and the rotor of the generator can be driven by the rotation of the power engine, and the generator will output induced electromotive force by using the principle of 'electromagnetic induction', and the current can be generated through the closed load loop. ”

In the mid-19th century, the importance of gasoline was not yet recognized, and kerosene for lighting lamps was used in large quantities. Petroleum refining at that time relied on a simple distillation process to separate the components of the oil with different boiling points. Kerosene has a high boiling point and is safe to use when lit, making it the main product of crude oil refining, while gasoline and other components are often burned as fuel. In the mid-to-late 19th century, the internal combustion engine that used gasoline was created, and in 1886, the gasoline engine was successfully operated as a vehicle power, and the importance of gasoline increased day by day. However, by distillation, only 20% of gasoline can be extracted from crude oil. In 1911, the Standard Oil Company of the United States solved the problem of low gasoline yield and adopted the William Oil. Burton and Robert. Hamfris invented the thermal cracking process, which heats and cracks heavy gas oil into fractions such as light gasoline, thereby improving the overall gasoline yield, and the thermal cracking process was granted a U.S. patent in 1913. The subsequent catalytic cracking process further improved the gasoline yield and achieved a higher octane number than the thermal cracking process.

The steam engine, the internal combustion engine, these are all milestones in scientific progress! Chongzhen Emperor Zhu Youzhen looked at Xu Guangqi in awe at the gasoline engine and smiled slightly. (To be continued......)
