The roar of Miles in the private room one after another, scared the waiters outside one by one.

As for the Cai Weiguo and others in the private room, they were even more panicked, but no one spoke to stop it. The reason is simple. If it is really like what Miles said, Cao Jiefang is in joy, then Miles should be happy. , And then calmly let Wei Hui's tongue expose Cao Jiefang's lies, thus making the Tengfei Group lose face in front of the people of the whole country.

But now Miles is like a resentful woman whose husband was snatched by a vixen, desperate and hoarse. Obviously Cao Jiefang's remarks in the interview directly hit Miles's weakness and hit GE's vitals, otherwise what? Maybe this is the reaction?

This is indeed the case.

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

However, both the Hentov Power Station and the McKinlish Power Station use natural gas as the fuel for gas turbines, and the compressed air stored in abandoned underground mines is only used as an auxiliary medium for natural gas combustion.

Because of this, not only did the two power stations fail to achieve zero emissions, but the thermal efficiency is similar to the traditional gas turbine-natural gas power generation combination, maintaining between 50% and 55%.

But this does not prevent Germany and the United States from propagating such development models as advanced environmental protection models. The problem is that countries or corporate organizations with a certain perspective can see the essence of the United States and Germany models at a glance.

The reuse of abandoned mines is just a gimmick. Natural gas combined with gas turbine power generation is the essence.

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

The problem is that this kind of tasteless upgrade has no effect except for the high price. Anyway, it is all using natural gas to generate electricity. Why should we spend two or three times more money to repair power stations on abandoned mines? As long as the supply of natural gas is enough to build a cheap ordinary power station, isn't it good for him?

This is also an important reason why after the United States and Germany launched air energy storage power stations, admirers were overwhelmed, but there were few who actually entered the pit. After all, there are not many countries in the world with online IQs, and no one wants to do the United States and German takers.

However, the real realization of zero emissions in the air energy storage power station of Ascendas Group is different. The large amount of heat generated in the process of using compressed air is stored through a heat converter. When power generation is needed, the heat converter is used to heat the air to make it It reaches a high temperature of several hundred or thousands of degrees; then the gas turbine is introduced to drive the turbine to rotate and do work, and finally electricity is generated through the generator.

There is no fossil fuel in the whole composition, and it is a thermodynamic transformation that even junior high school students understand.

The problem is that it is such a simple mutual conversion principle, but it is really difficult to do it.

First of all, the efficiency of the air compressor must be extremely high, otherwise the compressed air with high heat energy cannot be obtained at all, and the effective conversion of heat energy will naturally not be achieved.

The second is that the energy loss of the heat converter must be able to be controlled at a very low level. That is to say, after the heat energy of the compressed air is absorbed by the heat converter, it can maintain a very high temperature for a long time, so that it can be effectively heated. Compressed air used for power generation.

Finally, and most importantly, it is necessary to fully understand the various technologies of gas turbines, especially the combustion chamber, because this type of ultra-high heat source imported from the outside is also called external combustion chamber in the gas turbine field. If relevant production units If you are not precise enough to master all aspects of the gas turbine, the thermal efficiency of the gas turbine will be reduced if such an external combustion chamber is made, which will lead to the unsatisfactory efficiency of the entire generator set.

All in all, this kind of zero-emission air energy storage power station is just like an aero engine. Except for the simple principle, every other node is a super difficult point that can make the engineer's hairline completely disappear.

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

It's not that I don't want to, but the technical requirements are too high and the realization is too difficult. It is really impossible for a concubine to do it.

As a result, the Ascendas Group not only achieved this kind of technology that even the United States and Germany could not achieve, but also had very good thermal efficiency. According to Cao Jiefang's statement, it could reach about 55%, and it could be further increased to 60% in the future.

Even if Myers feels that the values ​​of 55% and 60% are a bit distorted, with the efficiency of a gas turbine, the thermal efficiency of 40% to 45% is still there.

Calculated based on the minimum value of 40%, the attractiveness to certain regions and countries is equally terrifying.

Because this zero-emission air energy storage power station does not require any fossil fuels, only the heat transfer medium that can be sealed into the heat exchanger by compressed air can be used as a large energy storage battery for cities or large enterprises, providing them with a steady stream of electricity .

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

You must know that this is only the cost saved by the pure fuel price. If you want to transport natural gas or oil to the power station, the oil and gas pipeline needs to be constructed. Does the construction cost have to be included?

Does the pipeline need regular maintenance?

Should maintenance costs be included?

In addition to pipelines, natural gas and oil also need to be stored, and the construction and maintenance costs of storage warehouses are another large amount.

Adding bits and pieces together, the life-cycle savings are more than tens of millions of dollars, and hundreds of millions are sprinkled with water.

Such a cost-effective throttling effect is placed here, not to mention the 40% thermal efficiency, even if it is only 30%, certain countries and regions will squeeze their heads.

So the question is, will Ascendas Group swallow this market in one go.

With Miles’ observation of Ascendas Group for so long, let alone the air energy storage power plant market, it is the entire global gas turbine market. Ascendas Group is ready to look forward to it and take a few bites~www.readwn.com~ such a good opportunity Before our eyes, it would be strange if the Ascendas Group did not win.

But in this way, for GE, not only will it fail to contain Ascendas Group, it is even possible that Ascendas Group will take a considerable market share in future competition.

What's more terrible is that in the face of Ascendas Group's zero-emission air energy storage power station, GE has nothing to do, let alone stop it without even competing products.

On the contrary, Ascendas Group can use this to enter the US and European markets, and in turn harvest the leeks in the backyards of GE and Siemens.

And this is why Miles yelled Cao Jiefang so uncharacteristically that Cao Jiefang lied. There is no way, even if it’s not a lie, it’s a lie. Otherwise, the matter will reach the GE headquarters in the United States. He, the vice president who is leading the suppression of Ascendas Group, will even even his opponent. If he doesn't know such an important technical achievement, then he doesn't have to mix in GE, and just leave it all!
