1254,Triple-expansion steam engine special warship
The group left the restaurant and came to the river.
The Hun River is a major river near Shenyang. The Hun River was called Shenshui in ancient times and was also called the Xiaoliao River.
Historically, it was the largest tributary of the Liao River. This river originates from the Changbai Mountains. It flows through Fushun and Shenyang, and then merges with Panjin and the Taizi River to form the Daliao River. The mouth of the Liao River is the seaport city of Yingkou. However, Yingkou was not built until the late Qing Dynasty. A small fishing village.
This ship is not small and uses the latest small steam engines. It is designed to be a combination of a shallow-water heavy gunship and a sea-going ship. It can sail in both inland rivers and offshore waters.
This steam engine is the first batch of trial-produced triple-expansion steam engines. The so-called triple-expansion steam engine has three cylinders. Because the steam coming out of the first cylinder is still very hot, it is very wasteful to discharge it directly.
If you introduce the hot gas into the second cylinder to continue to do work, and then discharge the hot gas to the third cylinder to continue to do work. In this way, you can see that the steam is used three times. The hot gas is fully utilized. By the time the third cylinder exhausts the gas, the temperature has already Greatly reduced.
During the Sino-Japanese War of 1894, the cruiser Yoshino could reach a speed of 21 knots, far exceeding the warships of the Beiyang Navy. The main reason was that its power system was a triple-expansion steam engine.
This is equivalent to connecting three cylinders in series. The smallest cylinder produces half the force. This greatly improves the thermal efficiency without increasing the boiler.
Because this ship is a special operations ship, it must be able to disguise itself as a merchant ship. It cannot use a bulky steam engine.
Therefore, this ship used a small steam engine that burned heavy oil and was modified using modern old steel pipes and old cylinders. The first mass-produced triple-expansion steam engines were divided into light and heavy types.
The heavy ones are used for warships, and the light ones are used for special ships and small inland river vessels.
On the pier by the river, there are densely packed merchant ships docked.
Many of these merchant ships came from the Ming Dynasty and North Korea. Daikin very much welcomed merchants to do business in Liaodong.
Because their daily necessities are too scarce. They do not lack alluvial gold, furs, silver and various products unique to Liaodong. What they lack is food and daily necessities.
A group of people carried the still unconscious members of the Shenyang Station onto the boat. Then they put them into the bottom warehouse and asked Guo Chengwen to take care of them. Then the boat quietly weighed anchor and used bamboo poles to prop it up silently south along the river. Go to the Hu family shack village ten miles away.
The Hujia Shack Village is located at a bend in the Hun River, in a small mountain depression three miles away.
There are more than a hundred stone houses here, and it is a small mountain village. Because it is surrounded by mountains on three sides, and only the west is a plain, the terrain is relatively hidden. This is a secret stronghold of Li Yangeng.
Hong'er and Zhu Zhu put on stab-proof clothing, inserted steel plates into their clothes, and put on helmets. Then Hong'er's fifteen people, Zhu Zhu's thirty people, and a servant from Xiao Qi also opened the box. , put on the stab-proof clothing that came with the ship.
General Banner Dong Jin used a crowbar to pry open a box.
Revealing revolvers stuck in wooden frames and arranged in rows inside. He said: "You have all used fire guns, right? This is a revolver that uses fixed bullets. It can fire six bullets continuously and has a range of fifty meters."
Dong Jin said, took out one and started to show how to use it.
"There is such a good thing, it's so convenient." Zhu Zhu said with admiration as he held it.
Before, they only had flintlock short-hand guns, which needed to be loaded in advance. It was very troublesome to load the powder. Yang Fan directly made a double-barreled one, so that he could fire two rounds at a time. The double barrels are heavy, and one person can carry two.
Tired. After the fight, reloading takes time. This is the most dangerous time, the enemy may rush over.
The revolver is dark and does not reflect light at night. It is also lightweight.
Dong Jin said: "When firing for the first time, you must use your thumb to lift the hammer. Remember, don't forget."
Although you have to reload after firing six rounds, there is a loader that can load six rounds at a time, which is very convenient.
Seeing that everyone had learned how to do it, Dong Jin gave everyone 240 rounds of ammunition, enough to reload forty times.
Then he pried open a box, which was full of grenades. Four more grenades were given to everyone.
The servants took out six more gunpowder-propelled grenades and carried them on their shoulders. This thing is a launch tube made of thick paper shells. It can be used once and thrown away after being fired. It does not occupy the staff.
"Bring the explosives with you. The village walls and houses are made of stone. They may need to be blasted to open a way." Dong Jin said.
The people at the pillar picked up ten steel crossbows and brought them with them. These things made no sound in the dark, which made them easier to detect hidden whistles.
The servants are regular soldiers, and their fighting abilities are not comparable to those of Zhuzi's men and Hong'er's men. This is why Hong'er dares to attack the Hu family's shack directly. There are solid stone walls in that place, which is easy to defend and difficult to attack.
And I don’t know where and how many people Li Yangeng released.
Because it was midnight, the steam engine could not be started, so everyone had to get on the deck and use bamboo poles to punt the boat away from the dock.
Eton is a small patrol inspector, he is responsible for collecting taxes here.
He got up to urinate in the middle of the night and seemed to see a boat leaving the dock. He was a little confused. What were these people doing moving the boat in the middle of the night?
Immediately, it saw a merchant ship that had arrived ten days ago, seemingly from Tianjin.
Why did you leave in the middle of the night and be stranded in the dark? He thought for a while, this ship had paid taxes. He didn't think much about it. As long as you paid taxes, I don't care what you do. He went back to sleep.
.
After leaving the dock, there was no one around. Autumn in Liaodong is the time of continuous autumn rain. The river is wide and the water volume is large. Both sides of the river are barren fields and the ruins of former villages.
Over the years since the founding of the slaves, things have gotten worse and worse. Even the area around Shenyang is in dilapidated condition. Production is completely abandoned. There are only a small number of nobles who still have a large number of slaves working in the manors, but some people often escape. Moreover, the efficiency is extremely low, and the production
Very little comes out.
The captain is Huang Hao's subordinate, named Li Anshi.
Seeing that he had left the dock, he ordered the chimney to be installed and the steam engine to be lit.
This chapter is not over yet, please click on the next page to continue reading the exciting content! The boat floated quietly along the river while lighting the boiler. The boiler uses a mixture of heavy oil and coal as fuel. This has the same benefit, that is, the temperature rises specially
Quickly. The flames became fierce in an instant.
After half an hour, the steam pressure is enough.
At this time, the boat had reached the river near the Hu family's shack and slowly docked on the edge of the river embankment.
The boiler maintained firepower and the steam maintained pressure. For fear of alarming the enemy, they did not dare to sound the whistle. Instead, they used a pressure relief valve to release excess steam.
"Captain Li, how are the preparations for the steam engine going?" Hong'er asked. "Let's go down now and we'll be back in an hour. There may be pursuers. We'll leave here at full speed as soon as we get on the ship."
"I know that the steam pressure is enough now. We maintain the boiler firepower. Once you get on the ship, we can start the propeller immediately. The triple-expansion steam engine can at least make the ship reach a speed of more than fifteen knots. We are going downstream again.
The water flow is also very fast, the actual speed is estimated to be 20 to 25 knots. They can't catch up with us."
Hong'er nodded and said: "There are Eight Banners military camps along the way, and the cavalry may come to chase us. We also have to pass through Panjin City, where there is a fort for establishing slaves."
Dong Jin said: "We are going very fast, and if we go down the river, we will definitely be able to leave the mouth of the Liaohe River and enter the Bohai Bay before dawn. The fort can't see the river clearly at night, so don't worry. Moreover, we read the intelligence before coming here. Jian Nu
The fort was built during the Hongwu period, and the cannons on it are all general cannons with a range of only 500 meters. They cannot hit us."
Hong'er was completely relieved. As soon as he reached the sea, Jiannu felt helpless.
