At the beginning of the new semester, the school has prepared the most traditional meal for junior students: course design.
As someone who has experienced it, although Zhou Yan already knew the content of the course design, he was still embarrassed when he saw "Power Plant Boiler Curriculum Design".
Although the school temporarily changed the training direction of the thermal energy major from power plants to automobile engines, the two professional courses "Construction and Principles of Internal Combustion Engines" and "Internal Combustion Engines" are simply not enough to support the students' professional level and professional skills.
The current boiler course design seems to be designed to make up for the lack of engine direction.
The course design tasks for all students were similar: design of a power station boiler with subcritical parameters and an evaporation capacity of 410 tons.
The only difference in the mission statement is the type of fuel: although they are both coal, their composition and calorific value are completely different.
After getting the course design task book and course design reference materials, a group of newbies immersed themselves in calculation and started calculating.
The teacher didn't say it, so the students naturally wouldn't know: among the top ten boiler plants in the country, only four or five can produce boilers above subcritical parameters.
Although Zhou Yan's classmates have all learned about boilers, their impressions of boilers have always been on paper. They only know that the specifications of power plant units are divided into three hundred thousand kilowatts, six hundred thousand kilowatts, and nine hundred thousand kilowatts.
Waiting for the series, more specific things, a black eye...
What a group of students don't even know is that the 410-ton boiler they are designing is suitable for a unit of 125,000 kilowatts. This is a very embarrassing existence: the country is considering phasing out boilers with a capacity of less than 300,000 kilowatts.
Thermal Power.
In his previous life, Zhou Yan worked as an equipment installer, so he was no stranger to boilers ranging from 100 to 500 tons. In order to deal with endless problems from Party A and supervisors, he also specialized in various calculations...
The second day of the new semester is the Lantern Festival.
During the festival of reunion, a group of young people who are alone in a foreign land always hug together to keep warm.
The new semester has just begun, and everyone’s wallets are still bulging. Naturally, they will not consider making their own food during the holidays, or just make a living, and just eat hard food and eat stir-fried vegetables.
A group of people have been together for two and a half years, and they are very familiar with each other. After sitting down, there is no need to be polite, and everyone has a bottle.
"Comrades, the new year has begun again. We will be together for three years soon, and today is the Lantern Festival. We wish ourselves a happy holiday!"
"Happy Lantern Festival!"
Although Zhou Yan had already settled in before going out, the party was about to start, and Zhou Yan's cell phone rang again. Naturally, there was no one else calling...
"Hey, wife, I'm eating out with my classmates..."
When Zhou Yan came back from the phone call, he found that everyone who had eaten was staring at him eagerly.
Zhou Yan was stared at and felt a little scared: "What's wrong?"
"Lao Zhou, have you changed your mobile phone?" This is Lin Junfeng.
"The sun comes out from the west?" It was Zuo Jiyun who said this.
"What's so strange?" Zhou Yan put the phone on the table and handed it to Zhao Ruijie, who stretched out his hand, "Some brand..."
Zhao Ruijie looked at them for a while, and then his phone was snatched away by Zuo Jiyun...
“It’s really a brand name!”
"Let me take a look..."
There was still class the next day, and a group of people didn’t dare to exert force when drinking, so that when the party ended, everyone was still in high spirits.
Although it is the Lantern Festival, a group of people are relatively homebound. They are either going back to their dormitories or their residences. They have no intention of going to Xinghuo Square to watch the fireworks...
After the Lantern Festival, curriculum design continues.
As someone who has experienced it, the thermal calculation of boilers is naturally a piece of cake for Zhou Yan.
Zhou Yan is almost beautiful, but the friends around him are anxious. However, there is no end to the road: Although the professional setting of the 2006 class has been changed, the content of the course design has not been changed. Zhou Yan’s clever little dormitory
Damn, I borrowed previous course designs from previous students.
The instructor of the course design quickly noticed the students' little behavior. After taking a look at the previous curriculum, he returned it.
"This classmate, there are many errors in the calculations here. It is recommended not to copy them..."
The settings of the boiler parameters in the course design are fixed: feed water temperature, steam pressure and temperature.
However, the teacher gave different fuels to all the students. Although many of them received the same type of coal, the specific composition and calorific value were all very different.
The ingredients are different, and the calculation process is naturally different. It can only be used as a reference and cannot be copied.
For Zhou Yan, it is enough to refer to it, and the course design textbook has a complete structural calculation and thermal calculation process.
When he was free at night, Zhou Yan had already made the calculation process into a spreadsheet, and all that was left was to fill in the data and make adjustments.
Zhou Yan, who was already familiar with boiler thermal calculations, completed the final thermal calculations in just two days.
According to the normal progress, the course design tasks assigned by the school include completing the thermal calculations and drawing the boiler general diagram, which is considered completed.
However, for Zhou Yan, who has a bit of obsessive-compulsive disorder and a Versailles tendency, the design of a boiler is not completed just after completing the thermal calculation...
The entire boiler is supported by a steel structure of nearly 100 meters. The foundation needs to be calculated for load, and the steel structure needs to be calculated for strength.
When the boiler is running, the smoke and air resistance needs to be calculated, and the resistance of steam and water needs to be calculated; the safety valve at the steam outlet needs to have a displacement calculation.
The pressure components used on the heating surface of the boiler require strength calculations. The strength and resistance calculations of the boiler are still calculated as a whole, and there are some local calculations that are more troublesome: the steam-water separation point, the highest wall temperature point of the superheater...
After completing the calculation, the designer also needs to provide the user with the boiler general diagram, steam and water flow diagram, thermal expansion system diagram, design instructions, installation instructions, usage instructions...
After Zhou Yan followed the formal design process and submitted all the drawings and materials, he immediately stopped the tutor: "This student, did you do all of this yourself?"
In order to get good results in course design, Zhou Yan could only take out all the reference materials and calculation data...
Zhou Yan completed the one-month course design in just one week. In addition to the strong need to pretend, there was another reason: Saturday was Valentine's Day...
On Friday afternoon, Zhou Yan freshened himself up, rushed to Yunzhong Airport, and took a direct flight to Xinhai.
We took off at around two in the afternoon and arrived at Xinhai. It was already sunset. Hannah, the "Fourth Tool Man" who picked up the plane, saw Zhou Yan and directly extended her sinful little hand: "Boss, this is considered overtime, so you need to pay extra!"
"
"All I know is money," Zhou Yan rolled his eyes, "I saw your ship design plan, and there's nothing wrong with it, but..."
"Just what?"
"We are engaged in shipwreck salvage, don't tell me, the underwater operations are all done manually," Zhou Yan curled his lips, "Hurry up and purchase the underwater robots used for the operations. Who knows one day Batumi will suddenly get crazy and use the underwater robots for the operations.
Robots have been put on the banned list. When the time comes, if you want to cry, there will be no place to cry!"
"That's right..." Hannah frowned, "I'll take care of this right away..."
"And..." Zhou Yan glanced at the Sihuan S8 in front of him, "I have my 28 ready for tomorrow, I want to use it!"
