Polu stood on the console and pushed the two joysticks in his hands. They controlled the magic supply and the throttle valve of the boiler respectively. The steam that had maintained pressure after the ship stopped opened the pressure limiting valve and sprayed out continuously.
.So when the predetermined passage is opened, the steam that is ready to move rushes into the cylinder through the opened throttle valve.
Polet, who was squatting in the engine room, used a lever to pry the stationary flywheel and let it rotate slightly. The two-way cylinder started, driving the thick crankshaft to rotate, and this powerful power was transmitted to the main shaft.
, forcing the propeller to stir up water.
The boat gradually accelerated, the river wind picked up slightly, and a white trail was dragged behind the stern of the boat, quickly heading towards the center of the river.
"Forward two!"
Everyone felt that the bow of the ship rose slightly, more steam gushes out of the cylinder, and more energy is input into the boiler. Standing on the deck, they can feel the slight vibration from the engine. Because Bolu's steam engine has not yet
It has developed to the level of triple expansion, so the steam that still has pressure is sprayed out from the iron pipes on both sides. They push open the water-blocking cover and make a chugging sound. They pull out white tails in the air.
cigarette.
Although there is no soot smell and the smoke is white, Bolu is still excited: "It smells like smoke! It smells like smoke!"
In order to increase the thrust-to-weight ratio of the steam engine, he tried every means to improve the efficiency of boiling water. After all, magic power is used to boil water now. Is it unnecessary to use fire to heat water across steel plates?
The first person to participate in the experiment was a heat pipe boiler, but it was quickly eliminated. Because using a heat pipe boiler requires an additional combustion chamber to heat the air, it increases the volume of the entire system.
Until he remembered the fear of being dominated by the scorching ray. Stricken by inspiration, Polu redeveloped the structure of the steam engine.
Steam engines in newly developed areas have lost their iconic black boilers. Today's steam engine boilers are composed of two pressure vessels that look like gas cylinders. It can be said that these two simple-looking gas cylinders represent the local metallurgical industry.
The highest level.
The boiler uses T1 alloy, and a spiral lock is used for ease of maintenance. In this boiler, there is no compartment for flame burning. Even the magic flame cannot burn in water. The mechanical disc controls the glowing ray substrate in the pressure vessel.
Energy supply. The scorching rays emitted in pulse mode are burning a copper rod nested in a hollow steel sleeve. When the copper rod is burned, it will melt first, and then conduct the heat to the steel shell, surrounding it.
The water vaporizes.
In this way, the copper rod is repeatedly melted and cooled, and the unique thermal conductivity can conduct the heat gathered at one point to the outer steel jacket, increasing the heating area. As long as the water in the boiler is not dry, it will not burn through the outer steel jacket.
As for water replenishment, it is completed by a set of steam-driven lever-type high-pressure double-door water pumps.
These steel sleeves look like electrodes that extend into the boiler, constantly evaporating soft water into steam, achieving great steam pressure.
This new boiler is much more efficient at obtaining air pressure than before. There is no need to burn hot water for 20 minutes before departure. Of course, the energy consumption is also extremely high. Two boilers require the supply of 8 energy-concentrating panels. Due to the problem that the energy-concentrating panels cannot be superimposed
, the arrangement of the eight energy-gathering panels troubled Polu a lot, and in the end he could only solve it by laying them flat on the deck.
If you simply rely on stacking energy-concentrating panels, the weight of the energy-concentrating panels will soon begin to reduce efficiency.
It's time to develop new technologies.
The ship has been traveling at high speed for some time. Polu asked from the building: "Everyone, I am going to travel at the highest speed. Are you okay?"
"Can you still speed up? Hurry up and push forward!"
"Okay! Go forward three!"
All the lines were connected, and the violent magic power was input into the ray generating plate. The rays were generated almost twice per second. The propeller rotated at high speed, and the water spray was driven in from under the stern of the ship. After a short distance, it turned into rolling white waves.
emerged from the water.
The wind brought fresh water vapor from the river in. Polu looked down and saw Leah and little Irene, who were wearing casual clothes today, sitting on the bench on the front deck. Their long hair was fluttering in the wind, revealing their beautiful collarbones.
and the beautiful curves of her slender neck, looking quietly ahead.
Leonardo stood on the guardrail of the bow and posed with his arms folded across his chest.
The wind on the small ship building blew Zhu Yiwei's hair, and a faint fragrance penetrated Bolu's nose. He couldn't help but turn his head and looked, but he was surprised to see a little smile on her usually frosty face, as if she had a smile.
Starlight's eyes narrowed slightly, seeming to be enjoying this moment that was not in line with the image of an orthodox mage.
As if seeing the smile of the goddess of magic, Boru relied on his strong heart to steady his trembling hands and did not drive the boat to the shore.
Little Irene suddenly jumped up from the stool. She was bouncing like a child. It seemed that she finally remembered her true age. She smiled and turned around and raised her hand: "Polu! That's the direction of the mine over there."
!Yes, you can enter through this river mouth!" After saying that, she smoothed her bangs that were blown away by the wind.
"Got it! Let's go take a look later!"
"Don't! It's not close after you go in! That place is quite far! Go there next time when you're ready!"
"Okay! Let's go to the royal capital today!"
"What! Do you know how far away the capital is!"
"It can be driven! Trust me!"
The boat cut a white trace on the river, chasing the floating clouds. The still life on both sides of the river slowly moved backwards. Leah and little Irene giggled on the deck, not knowing what they were talking about.
Bolu's ears were filled with the sound of wind, and he couldn't hear clearly what they were saying. Of course, if he could hear it, he would break out in a cold sweat.
"Lea, won't you go up?"
"What are you doing up there? It's not like you can't hear me. These two people haven't spoken to each other until now. Besides, I don't want to be crowded together with the mage. It's awkward."
"Isn't the atmosphere up there very awkward?"
"Isn't that a bad thing to say?"
"You can't hear the mage without casting spells, right? He didn't say anything bad about her at all?"
The two covered their mouths and laughed restrainedly.
Time passed quickly, and the walls of the royal capital appeared on the water.
"Not bad! Such speed!"
This place is different from the places in the south that are full of mining areas and cannot be farmed. There are still merchant ships around the royal capital, but what is surprising is that the ships here are very small, probably similar to the size of Boru's ship.
There are dense ropes tied to the bow of the ship, and they are dragged by the trackers on the shore, and they swim upward with difficulty. One ship after another, after all, there is only one road suitable for trackers to travel. Without independent power, it is difficult to overtake the ship.
Impossible.
Polu slowed down the boat, but even at this speed, it was as easy to overtake those boats towed by human power as a car overtaken a bicycle.
"Little Erin! Where are they going?"
"They're going to go upstream a little bit, then turn into the river that flows to the east, and then head towards Baator!"
"Why are the boats pulled manually? Isn't the speed too low?"
"What if we don't need to pull the boat? They don't have a steam engine!"
Business opportunity! Bolu has found another way to make money. If you collect my taxes, I will make a lot of your money!
Several beautifully crafted and ornately decorated boats suddenly appeared on the water ahead. Polu blew the whistle and turned the rudder to get far away.
"Look! The college's rowing!" Leah jumped up happily. She rushed to the side of the boat and waved to them: "Hey! Little guys! Come on! Let's row!"
"Come on, come on!" one of them responded.
The few people who were swaying and lazily on the boat suddenly sat up straight and started rowing suddenly in a catapult-like attitude.
"Lia? What's going on?" Polu, who was standing on the ship building, shouted down.
"Ah! That's a training event! I'll explain it later, just don't lose!"
Fergie and his teammates were paddling hard: "That's Leah, right? Didn't she go to Red Mountain? Why did she come back again?"
"Do you care if she comes back? Hurry up and plan carefully. Don't be embarrassed if you lose!"
"Her boat is weird. What kind of boat is it?"
Fergie raised his head and said: "Stop talking, row seriously, look at this situation, at least it is a boat built by an alchemist, take out all the fighting spirit!"
Everyone on this boat awakened their fighting spirit. They used their energy and shook the oars in their hands!
The boat suddenly split the waves on the water and moved forward quickly.
"Accelerate! Hurry! Don't lose! You must pass them at the wall pier in front!" Leah waved to Polu on the deck.
"good!"
Although I don’t quite understand what is going on, since it says to speed up, let’s do it.
Kick the accelerator to the bottom and the boiler overload begins!
Bang bang bang!
High-pressure steam was ejected from the exhaust pipe, spraying several smoke rings in the air. The roar of the cylinder gradually became more rapid and tight, and the sound of horse hooves was connected into a line, becoming like a sewing machine.
The bow of the boat suddenly lifted out of the water, revealing its slightly arced bottom, and its wide hull rushed forward at an astonishing speed.
In just ten seconds, Polu was already level with their boat. In the blink of an eye, their figures desperately and helplessly sliding the boat fell behind them. White water waves lined up beside their boat, splashing
The water spray turned them into drowned rats!
"It's over! The racing championship we have maintained for a year is over!"
"Don't, don't be afraid! Alchemy ships are prohibited from participating in racing boats!"
"This! This speed! What kind of ship is this? Such a big body can overtake us in an instant!"
"It's over! I've been fooled! If I treat her to this meal, won't she have to eat dirt next time?"
"Ah! My new clothes! They're wet again!"
Fergie put his paddle across his chest in frustration: "Such a big body! Can you also row a boat!?"
