Unlike Cai Weiguo, who is in the energy sector agencies and scientific research institutes, although Cao Jiefang has been clinging to GE's thighs and producing OEM foreign products, the overall situation is more realistic, not to mention that although the Jinling factory cannot get GE The latest products and core technologies, but the Jinling factory can still obtain some of the technical paths and development directions circulated in GE through personnel exchanges and inspections in the United States.
There are some things about coal chemical industry.
Are industrial gas turbine giants such as GE, Rolls-Royce, and Pratt & Whitney really unable to solve the technical problems in the coal chemical industry, as Cai Weiguo and other people in the energy sector say?
There is indeed no introduction in the public information, and there are no similar products in the product lines of several major giants. It seems that they have not made any achievements in the coal chemical industry.
But Cao Jiefang knew that as early as the 1970s, foreign industrial gas turbine giants had already 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 Middle Eastern oil-producing countries to impose an oil embargo on Western countries, the price of oil as a basic raw material soared, causing the United States and other Western countries to fall into an energy crisis.
Against this background, Western countries are hoping to find alternatives to oil to reduce their dependence on Middle East 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 was launched at this time.
However, nearly twenty years have passed, and why are there so few practical applications?
The reason is not difficult to guess. International oil prices have stabilized, especially since the mid-1980s, when prices have continued to fall. Cheap Middle Eastern oil has provided the Western chemical industry with stable and efficient basic materials. In-depth development based on coal has naturally become unavailable. Ask.
There is no way, although coal can be found everywhere and has certain advantages over oil in terms of price. However, if you want to use coal as a basic chemical raw material for deep processing like oil, the cost is at least 30% higher than that of oil.
Even if it is not used for chemical production, if it is simply used as a heat source for power generation, its efficiency is not as high as that of oil or natural gas. After all, the thermal efficiency of the two is there, and coal is naturally 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 need to install professional sulfur removal and slag removal equipment, which will inadvertently push up the cost of coal use.
Especially since the 1970s, with the large-scale application of industrial gas turbines, oil and natural gas have immediately become like a sleepy man meeting a pillow, a strong man meeting a beautiful girl, 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. The extracted oil or natural gas can be simply gasified or liquefied as fuel for industrial gas turbines, thus generating a steady stream of sufficient power.
This is why industrial gas turbines are widely used in fields such as oil exploration, drilling platforms, offshore oil and gas development, and petrochemical smelting.
In contrast, the application of industrial gas turbines in the coal field has been subject to many restrictions. First, the thermal efficiency of coal is insufficient. When the temperature in front of the turbine of an industrial gas turbine is generally around 1100 degrees Celsius, the work done by an industrial gas turbine using coal gas as fuel is only equivalent to that of an ordinary gas turbine. 32% to 36% of thermal power generation must be combined with steam turbines for combined cycle to reach the level of ordinary thermal power stations.
But only 70% of thermal power stations use oil and natural gas as raw materials and industrial gas turbines as the main kinetic energy.
The cost is 30% to 50% higher than ordinary coal thermal power generation or petroleum gas turbine power generation.
That's it. The key is that the service life of industrial gas turbines that use coal gas as the main raw material is surprisingly low, generally no more than 3,000 hours. The reason is also very simple. Coal is a solid fossil fuel. After gasification and separation, even if it is done in Fine, there will also be solid particles in the vapor.
It¡¯s just that the solid particles at this time are only a few microns in size and are difficult to detect with the naked eye.
However, 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 between two high-speed supersonic aircraft. The destructive force cannot be described in words. The working environment of the turbine is inherently It's terrible, and coupled with the torment of vaporized fuel with solid particles, no matter how good the turbine is, it can't bear it.
Because of this, giants such as GE have seen that following the path of coal chemical industry, not only will they spend a lot of money, but even if they are built, no one may buy it.
After all, oil and natural gas are already so cheap, and the supporting industrial gas turbines are so mature, who would bother to use them?Carbon?
In contrast, it is better to stick to the basics and make the cake of industrial gas turbines dedicated to oil and gas better than anything else.
Cao Jiefang thought this way before. This is the mainstream abroad. Domestic technology is far behind foreign technology. Who else can we refer to if we don¡¯t refer to foreign countries? So a few years ago, Li Tong and others came to say that they wanted to build a coal-specific Cao Jiefang, like Cai Weiguo and other people in the energy sector, thinks that industrial gas turbines for oil and natural gas are already good enough, so why bother with such nonsense?
So he politely declined, and he heard nothing after that. Cao Jiefang thought that this matter was just like other whimsical things, and finally let it go.
But it was unbelievable that today, a few years later, the newly released D-40t from Ascendas Group would actually achieve success in this regard.
The temperature in front of the turbine of 1250 degrees Celsius directly increases the hot sales ratio of the D-40t industrial gas turbine to 45%. Together with the steam gas turbine, it is 10% higher than the industrial gas turbine thermal power plant using oil and natural gas as fuel. %~15%.
Of course, what is more important is that the d-40t industrial gas turbine solves the problem of damage to equipment caused by fixed particles, greatly increasing the service life of the d-40t, thereby further reducing the cost of use.
It doesn¡¯t take much, just this one is enough to make the major coal-producing provinces in China flock to it.
What¡¯s more, it is said that Tengfei Group can also use the D-40t industrial gas turbine as the core to use coal to produce synthetic ammonia and other chemical raw materials, which will not only dilute the cost again, but more importantly, give greater enthusiasm to coal-producing provinces.
What is this if not changing the energy landscape?
¡¡
Cao Jiefang, who realized this, was already extremely shocked. But if he were at Mr. Li Tong's house in the capital at this moment, listening to Zhuang Jianye and Li Tong chatting while eating, he probably wouldn't be extremely shocked, but maybe his whole body would be directly shaken. Regarding petrochemicals, there is no way that Cao Jiefang's consciousness is too one-sided. The d-40t industrial gas turbine entered the coal field just to generate electricity and to synthesize ammonia? Changing the energy landscape?
That would be too underestimated the value of the d-40t industrial gas turbine. No, Zhuang Jianye flattered Li Tong by holding a chopstick of bamboo shoot tips while frying bacon, and said a heroic statement: "Next step, we are going to continue to work on the d-40t industrial gas turbine." - Continue research and development based on the 40t industrial gas turbine, and strive to use coal to develop most chemical raw materials and part of aviation fuel within five to ten years, further reduce the cost of deep processing of coal, gradually improve various processes, and formulate solutions that are in line with our own national conditions.
