Chapter 616: The Generator is progressing gratifyingly

In this case, it is a good time for the current development of 998, after all, for a period of time, with the start of new orders to produce, the factory's funds have become more relaxed.

After all, the annual export of alloy will reach more than one million tons, just this piece of alloy, Da Mao can bring almost 10 billion funds to the 998 factory, and the country can get more than 50 billion financial revenue on Da Mao, and the most important thing is that this does not expose too much strength, the metal exported to Da Mao is mainly concentrated in bearing steel, gear steel and other types of steel, plus pressure resistant alloys, but there are only five kinds.

It's just that the alloy exported later, mainly for civilian reasons, earned less, a ton earned 20,000 yuan, that is, about 6,000 rubles per ton, counting the cost, it was only reported 7 or 8 thousand rubles, in general, the other party is very satisfied with this price, after all, there is indeed a relatively large improvement in performance.

I just don't know what Da Mao's idea will be after the real strength of the 998 factory is exposed, after all, there are too many technologies in the factory that have surpassed them, even if it is the basic field of converter steelmaking, it has been at the forefront of the world, but because of more concerns, it has not been hyped up.

However, in Li Zhao's view, they will definitely not notice this situation for a while, without him, it is now November, and this year is almost over, and next year, it will definitely be overwhelming agricultural promotion news, which will definitely attract everyone's attention, after all, this is a promotion activity of hundreds of millions of acres.

A major event involving tens of millions of people, and there is a follow-up promotion plan, in the eyes of outsiders, this is definitely a major event involving the energy of the whole country. But the fact is that out of the 998 factory, a factory that does not need much attention from the state, a lot of good things have been made, and with the increase of time, there will be more and more such good things.

As for now, the work of tanks has come to an end in Li Zhao's place, and he has also begun to be mainly busy with other things, one of which is the generator set, which has now made obvious progress.

Regarding the tank, now Li Zhao often participates in the meetings of the research team, looks at the progress of the research, and then points out the next direction to the research team according to his insights, after all, the future improvement requires the participation of a large number of people, maybe it will not be long before Li Zhao will hand over the information of this tank.

In fact, except for the special majors of special schools, ordinary schools will not have such content, if Li Zhao went to a military factory or something like that, then he can only do miscellaneous work in some weapons projects at most, because in this aspect, he is actually similar to his classmates, and he is not familiar with it at all. If you want to make any progress, you can only learn from scratch little by little, and look forward to being able to take charge of yourself after a few years of study.

He's strong at machinery, not weapons, let's just say an artillery, if you want to really study it thoroughly, it's not something that you can do for a while, it looks like a very simple thing, but you haven't learned it, everything needs to be learned from scratch. The reason why Li Zhao is able to study tanks so unscrupulously now is entirely due to the many mechanical drawings he took out, which allowed him to show his prominence in only a small amount of time and become a master. ….

And if he went to a military factory, he wanted to attract the attention of his superiors, he had to come up with an epoch-making weapon, judging from his situation at the time, it was difficult, after all, just like the drone he was most familiar with, he also needed a lot of electronic talents to cooperate with him to come up with a more scummy one, but even if it was like this, it was not something he could do alone, and at Li Zhao's level, he couldn't handle the drone himself.

And after the 998 factory shows its prominence and becomes a big party, some people will pay attention to what he takes out, not to mention that the first leader in the factory is his father-in-law, the second in command is his elder, and he himself has become the third in command. The other leaders in the factory basically had to revolve around him, so that he could take this step in the tank project, if he was in a military factory, then he might be a researcher now, right?

Li Zhao was able to come to this point, and there was a lot of luck to tell the truth, if it wasn't for luck, he would probably still be rolling now

Upgrading machine tools in steel mills is at most just starting to test new machine tools, after all, those are not simple. Where is like now, directly out of a large group with an output value of tens of billions, machine tools are solving the problem of five axes, after a few years, when the computer can keep up, it is estimated that it will be able to develop more axis machine tools.

Basically, in terms of CNC machine tools, the 998 factory is already in the leading stage, and then there is a decade or twenty years of accumulation, which will become the mainstream of the world in the future competition of precision machine tools, leading the way.

The progress in civilian use is rapid, and Li Zhao has finally taken an important step in military equipment. In the future, he can basically guarantee smooth sailing, after all, compared with the tanks of this era, a tank of nearly sixty tons is too advanced.

At this time, after a period of research, calculation and repeated demonstration, the design details of each part of the generator set were basically perfected, especially the boiler and steam turbine, which need to withstand high pressure and high temperature, so the requirements for pressure-resistant metal are very high. However, this point is exactly what the 998 factory is most proud of, not to mention the research institute in the past two years, Li Zhao himself knows enough.

Li Zhao is not worried about this at all, after all, the best pressure-resistant alloy he took out at that time can be used for the reactor, and it is more than enough for the requirements that are only used in the critical unit now, that is, there are such conditions, so Li Zhao does not feel much pressure on the manufacture of the critical unit.

After all, the pressure required by the critical unit is only a little more than 22 megapascals, which is much higher than the current more than 10 megapascals, but for Li Zhao, it is really not a big problem, and with good materials, many problems that were very difficult in the past will be solved directly. Now it's just because Li Zhao is in contact with such equipment for the first time, so he should be more conservative, otherwise Li Zhao dares to design a higher and directly engage in a supercritical unit.

Of course, even so, the span designed by Li Zhao is very large, and the power of the generator set will reach 300,000 kilowatts, that is, three million megawatts. This unit can be said to be the general size of a thermal unit in the future, and it can be said that as long as it is successful, it will be enough for several decades. Of course, after the design is successful, Li Zhao is bound to lead people to continue to engage in supercritical, even ultra-supercritical, after all, to achieve ultra-supercritical, the efficiency is much higher. ….

The efficiency of the general subcritical generator set is generally only about 30 percent, and the coal consumption of one kilowatt-hour of electricity is basically more than one kilogram, and after exceeding the critical point, the basic efficiency can reach 38 percent, and the coal consumption can be reduced by more than 200 grams per kilowatt-hour of electricity, and the amount of coal used can be reduced by more than 20 percent. This is the money, basically one kilowatt-hour of electricity can save more than 30% of the cost, in this case, of course, it is worth it.

The ultra-supercritical is even more exaggerated, the efficiency of the power plant can be increased to 45 percent, and the coal consumption is nearly 400 grams lower than that of the subcritical unit, a drop of more than 30 percent, in this case, the power plant consumption can be reduced by more than 50 percent, so that the current electricity price of about two cents per kilowatt-hour will be reduced to about nine cents.

In this case, if ultra-supercritical units are used, the cost of the power plant next to it alone will reach more than 1 million yuan per day, and the annual savings will be about 600 million yuan, which is equivalent to 1 percent of the national fiscal revenue in this era, and one-tenth of the military expenditure will be saved.

Of course, it is unrealistic to want to make ultra-supercritical soon, it is estimated that Li Zhao will need to study for a long time, after all, the improvement of efficiency is not only required for the pressure and temperature of steam, but also related to how to boil water and how to design steam turbines. Lonely? At present, Li Zhao is engaged in critical units, and he can still eat some old books, but ultra-supercritical is simply impossible.

After all, now Li Zhao has the advantage of alloys, and the critical unit can be stacked directly with material properties, while the ultra-supercritical is simply impossible, even if you reach the pressure and temperature, but the efficiency of the steam turbine can't get up, then everything is virtual, after all, you need to convert the tangent pressure and temperature into the kinetic energy of the steam turbine, and you can't directly convert this pressure and temperature into electrical energy.

Of course, even if it is critical, it is very meaningful, after all, it can also reduce the cost by more than 30 percent, if they are replaced with critical units, then the power plant next door can also save more than 300 million costs every year, so even if it is a little worse, but it is also a big profit, after all, this saving is the money taken for nothing.
