Chapter 963

The roar of miles in the private room one after another scared the waiters out one by one.

As for Cai Weiguo and others in the private room, they were even more frightened, but no one said anything to stop them. The reason is very simple. If it is true that as miles said, Cao Jiefang is having a good time, miles should be happy. Then he calmly let Wei Hui expose Cao Jiefang's lies, so that Tengfei group will lose face in front of the people of the whole country.

But now Myers is just like a resentful wife whose husband was robbed by Fox spirits. He is angry and hoarse. It's obvious that Cao Jiefang's remarks in the interview directly hit Myers' weakness and hit the key of Ge. Otherwise, how could it be such a reaction?

It's true.

At present, there are only two air storage power stations in the world. One is Hentoff power station which was put into operation in Germany in 1979; the other is McKinley power station which was built in Alabama in 1991.

However, both Hentoff power station and McKinley power station use natural gas as the fuel of gas turbine, and the compressed air stored in underground abandoned mines is only used as the auxiliary medium of natural gas combustion.

Because of this, the two power stations not only failed to achieve zero emission, but also had the same thermal efficiency as the traditional gas turbine natural gas power generation combination, which maintained between 50% and 55%.

However, this does not prevent Germany and the United States from taking this kind of development model as an advanced environmental protection model to publicize. The problem is that countries or business organizations with a certain vision can see through the essence of the United States and Germany model at a glance.

The reuse of abandoned mines is just a gimmick, and the nature of natural gas combined with gas turbine power generation is.

If there is any difference, it is that Germany and the United States will use industrial gas turbines with higher thermal efficiency in air storage power stations.

The problem is that apart from being expensive, this kind of chicken like upgrade has no effect at all. Anyway, natural gas is used to generate electricity. Why should we spend two or three times more money on repairing power stations in abandoned mines? As long as the natural gas supply is up, he's building a cheap ordinary power station, isn't he?

This is also an important reason why after the United States and Germany launched air energy storage power stations, admirers are overwhelmed, but few of them are really trapped. After all, there are not many countries with online intelligence quotient in the world, and no one has any reason to blame the United States and Germany.

However, it is different for Tengfei group to realize zero emission of air energy storage power station. A large amount of heat generated in the process of using compressed air is stored by heat converter. When power generation is needed, the heat converter is used to heat the air to a high temperature of hundreds or thousands of degrees. Then the gas turbine is introduced to drive the turbine to rotate and do work, and finally the generator is used Generate electricity.

There is no fossil fuel in the whole composition, which is the mutual transformation of thermodynamics that even junior high school students understand.

The problem is that such a simple principle of mutual conversion is very difficult to implement.

First of all, the efficiency of the air compressor must be particularly high, otherwise the compressed air with high heat energy can not be converted effectively.

Secondly, the energy loss of the heat converter must be controlled at a very low level, that is to say, the heat energy of the compressed air can maintain a very high temperature for a long time after being absorbed by the heat converter, so as to effectively heat the compressed air used for power generation.

Finally, the most important thing is to have a thorough understanding of various technologies of gas turbine, especially the combustion chamber, because this kind of external combustion chamber is also called external combustion chamber in the field of gas turbine. If the relevant production units do not master all aspects of gas turbine accurately, it is easy to cause gas turbine failure The thermal efficiency decreases, which leads to the unsatisfactory efficiency of the whole generator set.

In a word, this kind of zero emission air storage power station is just like the aeroengine. Except for its simple principle, every other node is a super difficulty that can make the engineers' hairline disappear completely.

If not, don't the United States and Germany want zero emissions?

It's not that I don't want to, it's that the technical requirements are too high and it's too difficult to realize. I really can't do it.

As a result, Tengfei group has not only achieved this kind of technology that even the United States and Germany can not achieve, but also has very good thermal efficiency. According to Cao Jiefang, it can reach about 55%, and it can further increase to 60% in the future.

Even though Myers thinks that the 55% and 60% values are somewhat distorted, there is still 40% to 45% thermal efficiency with the efficiency of gas turbine.

According to the minimum value of 40%, the attraction to some specific regions and countries is also terrible.

Because this kind of zero emission air energy storage power station does not need any fossil fuel, only uses the heat conduction medium which can be sealed into the heat exchanger by compressed air, it can be used as the super large energy storage battery of cities or large enterprises to provide them with continuous power.

This is no longer a simple environmental problem for those specific countries and regions. The whole life cycle fuel cost alone can save tens of millions of dollars.

You know, this is just the cost saved by the simple fuel price. If you want to transport natural gas or oil to the power station, you need to build oil and gas pipelines. Do you have to include the construction cost?Does the pipeline need regular maintenance?

Do you want to include the cost of maintenance?

In addition to pipelines, natural gas and oil also need to be stored, and the cost of warehouse construction and maintenance is a large sum.

Piecemeal add up, life cycle savings are more than tens of millions of dollars, hundreds of millions of dollars are spilled.

Such a cost-effective throttling effect is here. Let alone 40% of the thermal efficiency, even if it is only 30%, specific countries and regions will be scrambling for it.

So the question is, will Tengfei group swallow this market.

Based on miles' observation of Tengfei group for such a long time, not to mention the air storage power station market, but the whole global gas turbine market, Tengfei group is ready to take a few bites.

With such a good opportunity in front of us, it's strange that Tengfei group won't win.

But in this way, for GE, it will not only fail to encircle Tengfei group, but may even be taken a considerable market share by Tengfei group in the future competition.

What's more, in the face of the zero emission air energy storage power station of Tengfei group, GE has nothing to do, let alone stop it.

On the contrary, Tengfei group can break into the U.S. and European markets, and in turn harvest leeks in the backyards of Ge and Siemens.

And that's why miles would cry out that Cao Jiefang lied in such an unusual way. If it wasn't lying, it would be lying. Otherwise, it would be spread to ge headquarters in the United States. He, the vice president of Tengfei group, who is leading the crackdown on Tengfei group, didn't even know his opponent's important technological achievements. Then he would not have to stay in Ge and go straight away ！
