Breakthroughs in large-scale precision machining capabilities will take time to develop, and steam turbines have already been used.
Before the institute joined the project, a lot of early work had been completed on the steam turbine unit, including the selection of alloy types for each component.
Although steam turbines are low-temperature equipment compared to gas turbines, to achieve higher thermal efficiency, the steam temperature still needs to reach between 500 and 600 degrees. In this temperature range, it must be protected from the strong corrosion effects of steam. Available steel types There are not many, including iron-nickel-manganese alloy, iron-nickel-cobalt alloy, iron-nickel-silicon-carbon cast iron, stainless steel, etc. Nickel or chromium are indispensable anti-corrosion elements. There may be other alloys that can achieve similar effects, but iron It’s useless to say that the factory can’t do it.
All metals have undergone relevant high-temperature steam corrosion experiments.
If the early work is done well, there will be no repetitions later. Not long after the bearing was produced, the heavy industry used a steam turbine-driven workshop power source.
The effects of steam turbines and reciprocating steam engines are completely different. The rotation speed of the turbine is calculated in thousands per minute. The existing workshop bearings have a riveted structure. They cannot withstand this speed and require gear sets for transfer. This is the work of other groups.
Regardless of the troubles in the process, after the steam turbine was connected to the power source of the processing workshop, the difference between shaft transmission and connecting rod transmission was used to achieve a limited improvement in processing accuracy.
The factory directors and workshop directors of the heavy industry were also very stupid. After the test, they replaced the power source of the bearing workshop with this steam turbine, and let the best workers operate it to process higher-precision bearings.
Although there is no way to repeat the nesting of dolls, the bearings made by the shaft drive have indeed improved slightly, and the noise of the whole machine has dropped significantly. This second set of steam turbines that was supposed to be delivered to Fenggu Power Plant was left at home and the prototype was sent. past!
Even if you are asked about it afterwards, you can call it a test.
When the Fenggu Power Plant received the steam turbine, I cried on the spot...not because I discovered something, but because I was happy.
Fenggu Power Plant is purely an unfair enterprise. Because of the high electricity prices caused by low power generation efficiency, it is unable to promote the process of civilian use. Their operations are all dependent on a few large power consumers, especially Fenggu Nonferrous and the current Rainbow Metal. There is no money to be made. I'm still frustrated. If it weren't for the official shares and subsidies, I would have been unwilling to do it.
As soon as the steam turbines were connected to the power grid, the power plant immediately shut down all the old steam engines. The efficiency was too far behind and the power was not the same.
Reciprocating steam engines do not use steam over 500 degrees at all. For them, there is not much difference between steam at 200 degrees and 500 degrees. 10% heat utilization is a super threshold. High steam temperature is a waste of fuel.
The power of the steam turbine ordered this time has reached 50 megawatts, but it is limited by the hot chicken generator from the motor factory. Two of the latest generators connected in series can only produce 22 megawatts of electricity. If it were not for the power axial The stability decreases with the number of series connections, and it must be connected to more than a dozen units.
In order to make good use of the steam turbine whose power limit is too high, after much deliberation, we still have to seek help from heavy industry.
Then another set of gear sets was ordered to complete the one-to-four power generation, with the output reaching 44 MW.
The power generation capacity of this power is just over one million kilowatt-hours per day. Regardless of the existing industrial power consumption, there is still a certain surplus, and Wang Tinglai's instructions can finally be carried out.
There was actually something wrong with Wang Ting's instructions. According to the instructions, Fenggu Electric Power was to merge with the newly built Obsidian Electric Power, and the shares were lost for no reason.
But it doesn't matter if you disagree, because the steam turbine they are using now has a quota for Obsidian Power, and if it is not incorporated, it will be squeezed to death immediately.
It does seem a bit domineering, but if you think about it carefully, Xincheng Heavy Industries, the Research Bureau, and the Manufacturing Bureau all belong to the Phoenix King. He can do whatever he likes, even squeezing out several companies without having to notify him. At least he still has options now, and in the future There is also profit.
After being merged into Obsidian Power, Xincheng Power automatically obtained the nationwide power grid operating license, and Obsidian Power was responsible for infrastructure development and paving.
The power system has a high status in Wang Qi's eyes, so the Obsidian Electric Power Company directly supervises it under his nose and is located on the third level platform of Wang Tingshu.
Wang Tingshu's second-level platform a few years ago has now been upgraded to level four. There are three more opposite-direction platforms between the first and second levels. And this development is not an impromptu initiative. Alfalfa connected the first- and second-level platforms as early as The decision was made when the overpass was decided, that is, before the seeds were planted. After all, the connection between the two platforms does not require the alfalfa type, and two lines can complete the rapid passage.
The alfalfa expressway is the connecting area of each platform. The south direction is the earliest first-level platform and the top-level platform; the north direction is the third-level platform. The current area is equivalent to 0.2 square kilometers when the first-level platform was just opened for civil real estate. Some official The headquarters of operating companies will be moved here, including Phoenix Bank, Obsidian Bank, and Obsidian Power; the east and west directions are at the same height and belong to the secondary platform. In order to maintain the stability of the overall center of gravity of Wangtingshu, these two directions must develop together, speed It is relatively slow, and the development level is currently low, and civil buildings have not yet been opened.
The edge of each platform will eventually fall to the inner side of the city wall. The third-level platform is directly connected to the inner side of the city wall through the root system of aerial roots. The root system of the second-level platform will develop into additional channels connecting the ground, and finally it will show a wide blooming petal. It is orchid-shaped, with the top platform and the Phoenix Palace being the core of the flower, but to reach this level requires a huge amount of nutrients, and it will take at least another five years to develop.
Back to Obsidian Power, the company's headquarters is located in Wangtingshu, which is very inconvenient to transport, and the wooden flame-retardant structure cannot completely eliminate the risk of fire, so the factory building is on the surface and was directly dumped in Nanzhen.
As the demonic activities became more and more rampant in South Town, the danger assessment of the forest area was improved, and some adjustments were made to its positioning. It became a major town similar to the golden red, more military-oriented. The second battalion of the 22nd Regiment, the 102nd Battalion, composed of mixed blood, was stationed in Here, the logging industry gradually moved to Dongshan Road and West Intersection east and west of the junction city. Only the mining industry, the production of new power transmission equipment, and the processing of alumina separated from the iron plant remained in Nanzhen.
Power delivery, perhaps somewhat surprisingly, relies heavily on...oil!
That's right, it's oil, not wire insulation or anything like that.
The north-south transmission mileage of the entire power grid is about 170 kilometers, and the farthest east-west direction is from Dongshan Road to the west intersection, a total of 75 kilometers. The core power generation area is the wind valley with relatively abundant water resources, and a smaller backup power generation area has been established in the new city, so in practice The maximum transmission distance is only 130 kilometers.
At this mileage, the voltage does not need to be particularly high.
Electrical knowledge tells us that current mainly flows through the surface of a conductor. The larger the surface area, the smoother the electric flux. Use one millimeter wire to make a stranded wire, and then twist several strands of stranded wires together to easily adapt to different conditions. High voltage transmission needs, even considering the continued expansion of territory in the future, 50,000 volts will be enough for a few years.
The voltage is limited, so there are many types of wires to choose from. At the same time, the requirements for insulators used in transmission towers are not that high. Generally, ceramics can be used. The outer layer of the cable is covered with paper, oil-impregnated cloth and resin coating. Use it and see.
Since we are starting from scratch, we deliberately avoid some of the pitfalls caused by the conversion from the imperial system to the metric system in the original world. We use a 50 Hz AC frequency, a city voltage of 200 volts, and an industrial power supply of 400 volts. The relationship between the integral multiples will make the line transformation difficult. easy.
The one that has a certain degree of difficulty is the step-up and step-down equipment. The relatively old-school oil-immersed transformer is still used here. The basic application capabilities are insufficient and the knowledge of power-related materials is not advanced. This method is still more reliable.
Oil is now dependent on imports, but considering the population consumption of the oil refining industry, we still have to compromise temporarily and wait and see if the population increase can reach a higher level next year.
The judgment of the increase in population sources comes from the movements of the demons.
