Chapter 724 Choice of Technical Route
It's different now!
Although the statistical results have not yet come out, Yang Dongsheng made a rough calculation. This year, Dongsheng Mining is expected to produce more than 3.5 million tons of coal and nearly 2 million tons of iron ore.

With the collective rise in mineral prices brought about by economic recovery, the profit of the entire Dongsheng Mining Industry this year will be more than 1000 billion.

This number will rise further in the future, which is why Yang Dongsheng dared to fight a bunch of Japanese companies.

After the symposium, Yang Dongsheng arranged a banquet with good wine and good food.

Back in the room, Vice President Zhao sent someone to deliver yogurt.

Yang Dongsheng drank yogurt, took a shower, and the security guards reported that Vice President Zhao had arrived.

"How are they?" Yang Dongsheng asked.

"Drink a little too much, but it's nothing serious. These people probably haven't had a decent banquet for a long time."

Yang Dongsheng thought for a while and said, "Don't let them go back to Jinyang, let them fly back to Shanghai with me the day after tomorrow!"

"Is this over?" Vice President Zhao was taken aback.

"Let them see the house first, so that they will be motivated!" Yang Dongsheng lowered his voice, "Go and find out the attitude of the Northwest Coal Chemical Institute, they can set the price whatever they want, but if they want the company's shares, we will just keep them Down!"

Since their technology is real, Yang Dongsheng can't let them go.

Back in Shanghai, as soon as he got to work, Vice President Wang from Dongsheng Heavy Industry came to him.

Vice President Wang first reported the research and development of small gas turbines below 15 MW.

Then he reported the progress of the Dongsheng-390 gas turbine manufactured for the Guazhou self-owned power plant. The power plant has been approved by the Suzhou government, and Suzhou is very interested in this gas turbine.

After reporting on the work, Vice President Wang said coyly, "President Yang, there is something that we are a little uncertain about!"

"what's up?"

"The company has some disagreements on the technical route of the next generation of gas turbines!"

"What difference?" Yang Dongsheng asked.

"One of the core technologies of a gas turbine is how to cool the blades! In the past, the technologies of various companies were similar to each other. Air was introduced, holes were punched on the blades, and an air film was formed on the surface of the blades. General Electric put forward the concept of closed-cycle steam cooling in 110, using steam instead of air to cool the blades. Steam is more efficient than pure air cooling, and they also recycle the steam for reuse. According to the publicity materials published by General Electric, in Under the condition of the same combustion chamber outlet temperature, closed steam cooling can increase the temperature of the first-stage moving blade by [-] degrees. This is a revolutionary technology. General Electric has come up with various technical indicators that meet the H-level requirements. Use closed-cycle steam-cooled gas turbines to build a demonstration power station!"

"Closed cycle steam cooling, which can be recycled, is indeed a good way!" Yang Dongsheng nodded.

"The problem now is that the people we recruited don't know much about closed-cycle steam cooling technology!" Vice President Wang became a little anxious when he heard what Yang Dongsheng said, "Now we know that closed-cycle steam cooling can be done H-class gas turbines have been produced, but we have too little accumulation of this technology. Even if we try our best to publicize closed-cycle steam cooling, we are not sure to overcome this problem in time; but if we only rely on open air cooling, can we reach the indicators of H-class gas turbines? , and not sure!"

After Vice President Wang finished speaking, he looked at Yang Dongsheng without blinking.

This really made Yang Dongsheng question. He was not an expert in gas turbines in his previous life. How would he know whether the H-class gas turbine should be cooled by closed cycle steam or open air?
Yang Dongsheng thought for a while and asked, "Isn't Siemens also developing H-class gas turbines? What kind of cooling method do they use?"

"Siemens insists on using open air cooling!" Vice President Wang replied immediately.

Yang Dongsheng glanced at him, he already knew the answer in his heart.

I came to see Yang Dongsheng today, but I was worried about choosing the wrong one, and I wanted someone to take the blame for him.

At first I thought he was quite an honest person, but now he is getting more and more slippery.

Yang Dongsheng leaned on the back of the chair, and deliberately emphasized his tone, "Just say it, I said it! Siemens has a deeper technical accumulation in gas turbines than ours. Since they insist on using open air cooling, they must have reached the threshold Yes, we also use open air cooling!"

Yang Dongsheng did not completely listen to Vice President Wang. According to Yang Dongsheng's knowledge, Mitsubishi lagged behind in the development of H-class gas turbines, but Siemens did not.

Vice President Wang hurriedly smiled, "Isn't it because they are fighting too hard? I can't hold back!"

After Vice President Wang left, Vice President Jiang came over again, firstly reported on the integration of oil extraction companies, and then said, "Two days ago, Yihai Group contacted us and wanted to buy out our wheat production for the next ten years! "

"Sure enough, they are looking at wheat again!" Yang Dongsheng said.

Yihai Group is an agricultural product processing enterprise jointly invested by American ADM (ADM), one of the four major grains, and Singapore Fengyi Company.

As early as a few months ago, Yang Dongsheng heard from James Whistler that Aidemo and Cargill would buy out their corn and wheat production for the next five years.

After successfully destroying China's oil-extracting enterprises and getting benefits, their ambitions were further stimulated, and they focused on wheat again.

No matter how high the price of soybeans is, if we don’t drink soy milk, cook vegetables, or eat meat, we won’t starve to death, but wheat is one of our staple foods. If the price of wheat is too high, people will really starve to death.

"First, ignore them; second, increase the proportion of wheat planting in the next few years!"

This time, Yang Dongsheng must not let them succeed.

Both Dongsheng Foods and Alice refused, but Yang Dongsheng wanted to see how they would continue to toss about food prices.

After a busy day, Vice President Zhao finally came over when he was about to leave work.

In the past two days, he ran to contact the leaders of the Northwest Coal Chemical Industry Institute, and took the carbon fiber research group to look at the house, so busy that he didn't touch the ground.

"Are they satisfied with the house? If not, you can take them to Huajing to have a look!" Yang Dongsheng said.

"You don't need to go to Huajing, they are very satisfied with the house! You didn't see it, those people cried when they saw the house!"

"It's not possible!" Yang Dongsheng was taken aback.

"You didn't go to the place where they live now. When the country started the third-line construction, the Northwest Coal Chemical Plant moved into the mountains around Jinyang. In the 80s, Sino-Soviet relations were normalized, and the pressure on the Americans was also reduced. , Coal chemical plants have moved out of the mountains one after another, but those who engage in carbon fiber still have to stay in the mountains, and the laboratories and living places are all adobe houses!"

"It's really better to sell tea eggs than those who engage in atomic bombs!" Yang Dongsheng sighed, "Where is the Northwest Coal Chemical Industry Institute?"
