Take Off My Aviation Era

This idea is not alarmist.

Different from Cai Weiguo’s people in energy departments and scientific research institutes, although Cao Jiefang has always been holding GE’s thighs and producing OEM foreign products, the overall situation is more realistic, not to mention that the Jinling plant can’t get GE. The latest products and core technologies of the company, but the technology path and development direction of GE, Jinling Factory can still obtain some through personnel exchanges and inspections in the United States.

Among them are some things about coal chemical industry.

Industrial gas turbine giants such as GE, Rolls-Royce, and Pratt & Whitney really, like Cai Weiguo and other energy departments, can't solve the technical problems of coal chemical industry?

The public information does not introduce it, and there are no similar products on the product lines of the major giants, which seems to have made no achievements in the coal chemical industry.

But Cao Jiefang knew that as early as the 1970s, foreign industrial gas turbine giants had tried to use coal as the main chemical raw material to gradually replace the widely used oil and natural gas.

Because the Fourth Middle East War caused oil-producing countries in the Middle East to impose an oil embargo on Western countries, the price of oil as a basic raw material soared, which caused the United States and other Western countries to fall into an energy crisis.

In this context, Western countries hope to find alternatives to oil, thereby reducing their dependence on Middle Eastern oil. Coal, as an energy raw material abundant in Western developed countries such as Europe and the United States, has naturally become the preferred alternative.

So in-depth development based on coal has been launched at this time.

However, nearly two decades have passed, why are there few practical applications?

The reason is not difficult to guess. International oil prices have stabilized, especially since the mid-1980s. Prices have continued to fall. Cheap Middle Eastern oil has given the Western chemical industry a stable and efficient basic material. In-depth development based on coal has naturally become unmanned. Ask for interest.

No way, regardless of the fact that coal is everywhere, it has certain advantages over oil in price. However, if you want to use coal as a basic chemical raw material for deep processing, the cost is at least 30% higher than that of oil.

Even if it is not used in chemical production, its efficiency is not as high as that of oil or natural gas when it is simply used as a heat source for power generation. After all, the thermal efficiency of the two is there. Naturally, coal is much lower than stone and natural gas.

That's all, the key is that the use of coal will also produce a lot of pollution. If you want to reduce pollution, you must use professional desulfurization and **** removal devices, which virtually pushes up the cost of coal use.

Especially since the 1970s, with the large-scale application of industrial gas turbines, oil and natural gas are immediately like sleepy meeting pillows, strong men meeting flower girls, and they are a perfect match.

Especially in the deep opening of oil or natural gas, there is no need to do too much processing, and the extracted oil or natural gas can be used as fuel for industrial gas turbines by simple gasification or liquefaction, thereby generating a steady stream of sufficient power.

And this is why industrial gas turbines are used on a large scale in fields such as petroleum exploration, drilling platforms, offshore oil and gas development, and petrochemical smelting.

In contrast, the application of industrial gas turbines in the coal field is subject to many restrictions. First, the thermal efficiency of coal is insufficient. When the temperature in front of industrial gas turbines is generally around 1100 degrees Celsius, industrial gas turbines using coal gas as fuel can only perform work equivalent to ordinary 32%~36% of thermal power generation must be combined with steam turbines for combined cycle to reach the level of ordinary thermal power plants.

But only oil and natural gas are used as raw materials, and industrial gas turbines are used as the main kinetic energy for 70% of thermal power stations.

The cost is 30% to 50% higher than ordinary coal thermal power generation or oil gas turbine power generation.

That's all. The key is that the service life of industrial gas turbines that use coal gas as the main raw material is surprisingly low, generally not exceeding 3000 hours. The reason is simple. Coal is a solid fossil fuel. After gasification and separation, even if it is done in Fine, there will be solid particles in the vapor.

It's just that the solid particles at this time are only a few microns in size, which is difficult to detect with the naked eye.

But these solid particles are a great test for the turbine of a high-speed industrial gas turbine. The process is no less than a head-on collision of two high-speed supersonic aircraft. The destructive power cannot be described in words. The working environment of the turbine is inherent Very bad, coupled with the toss of gasified fuel with solid particles, even the best turbine can't bear it.

Because of this, GE and other giants saw that based on the road along the coal chemical industry, not only did they have to spend a lot of money, even if they were made, they might not be bought.

After all, oil and natural gas are already so cheap, and the supporting industrial gas turbines are so mature, who still bother to use coal?

In contrast, we still stick to the basics and make the cake of industrial gas turbines dedicated to oil and gas better than anything else.

Cao thought the same way before the liberation. This is the case in the mainstream of foreign countries. The domestic technology is far worse than the foreign ones. If you don’t refer to foreign countries, you can refer to whom, so a few years ago, Li Tong and others asked for a coal special. Cao Jiefang, like Cai Weiguo and other people in the energy sector, thinks that the industrial gas turbines in China are whimsical. The industrial gas turbines for oil and natural gas are good enough, so what are they doing?

So he politely declined, and after not hearing anything, Cao Jiefang thought that this matter was the same as other whimsical things, and in the end it was nothing.

It's hard to imagine that today, a few years later, the newly released D-40T of Ascendas Group has achieved success in this regard.

The temperature in front of the turbine of 1250 degrees Celsius directly increases the proportion of D-40T industrial gas turbine power generation sales to 45%. Together with the cooperation of steam and gas turbines, it is 10 higher than that of industrial gas turbine thermal power plants using oil and natural gas as fuel. %~15%.

Of course, the more important thing is that the D-40T industrial gas turbine solves the problem of damage to equipment by fixed particles, which greatly increases the service life of D-40T, thereby further reducing the cost of use.

Needless to say, this one is enough to make the major domestic coal production provinces rush to ~www.readwn.com~ Moreover, it is said that Ascendas Group can also use D-40T industrial gas turbines as the core and use coal to produce synthetic ammonia and other chemical raw materials. The cost of dilution is more important to give the coal province greater enthusiasm.

Isn't this changing the energy landscape?

...

Cao Jiefang, who realized this, was already shocked, but if he was at the home of Mr. Li Tong in the capital, listening to Zhuang Jianye and Li Tong talking while eating, he would not be shocked, but the whole person might be directly. In the petrochemical industry, there is no way that Cao Jiefang's consciousness is too one-sided. The D-40T industrial gas turbine entered the coal field only to generate electricity and to make synthetic ammonia? Change the energy landscape?

That would be too underestimation of the value of the D-40T industrial gas turbine. No, Zhuang Jianye pleased Li Tong with a chopstick's bamboo shoot tip to fry bacon at the same time, and said a proud word: "Next we are going to continue in D —Continue research and development on the basis of 40T industrial gas turbines, and strive to use coal to develop most of the chemical raw materials and some aviation fuels within five to ten years, and further reduce the cost of coal deep processing, gradually improve various processes, and formulate a process that meets our national conditions. Industrial gas turbine standards."
