NGCC is the abbreviation of natural gas-steam combined cycle power generation technology, which originated in the fifties and has become one of the hot spots in the international power generation field since the seventies.

Compared with traditional coal-fired thermal power generation, NGCC has huge advantages in terms of cost and environmental protection, and industrial groups such as General Motors of the United States, Siemens of the Federal Republic of Germany, Mitsubishi of Japan, Rolls-Royce of the United Kingdom, Alstom of France, and Volvo of Sweden have invested heavily in the field of NGCC.

First of all, from the technical principle, one-third of the power generation of the combined cycle of the gas turbine comes from the steam turbine driven by the waste heat boiler, and the efficiency of the total plant is about 35% higher than that of coal power, which means that the same electric energy consumes about 35% less fuel, and the pollution caused by nature is less.

Secondly, the fuel used for gas turbine power generation is natural gas, the main component is methane (CH4), and the sulfide, soot and carbon dioxide generated by combustion are far less than that of coal turbines, especially LNG power generation after impurity pretreatment, the emission is only a quarter of that of traditional coal-fired power plants, and the pollution such as complex sulfides is almost zero.

Finally, due to the different combustion temperatures and mechanisms, the gas turbine can adopt the progressive dry low-nitrogen burner in nitrogen oxide control, which can effectively control the gas turbine emissions and achieve better gas turbine performance through homogeneous premixing and shortened combustion residence time.

Compared with the gas turbine, the principle of environmental protection of the coal machine is almost equal to washing clothes, and the emission of the coal machine is cleaned through environmental protection equipment, depending on the number of cleaning times to achieve low emission or ultra-low emission, and the pollutants are only suspended in the gaseous state of small particles into a solid or solid-liquid mixed state, which cannot fundamentally solve the environmental protection problem.

This is a report from the University of Hong Kong on gas turbines and steam turbines for combined power generation.

Since there is no similar heavy industry related to gas turbines on Hong Kong Island, and there are no R&D personnel in related fields, this report is a summary of trends made by a professor in the Department of Social and Economic Research of HKU who studies environmental protection.

Lu Zijiao has been staring at the NGCC data on the table for half an hour, and as a first-line reporter of the talented Sing Tao Daily, she has not experienced the feeling of Carvin for a long time.

Two days ago, Lu Zijiao received a "big job" worth 100,000 Hong Kong dollars to write a popular science article from the perspective of the people, scientifically discussing the fatal shortcomings of NGCC power generation compared with coal-fired power generation.

Along with the "big event" came a number of real technical information related to the industry.

Although I don't know what happened, the client of the project is also a non-profit organization called Lights Out Times, which is committed to promoting equality and equality, people's livelihood and civil rights, and environmental protection.

But Lu Zijiao's keen sense of smell still smelled a hint of the simmering tropical storm over the energy field on Hong Kong Island.

Usually, the price of the leading article on the first line of Hong Kong Island is only 10,000 yuan, don't look at the skin but the price is so refreshing, Lu Zijiao thinks that the client who is not bad for money is either Hutchison or Huadian.

But what exactly have these two Hong Kong Island energy giants encountered? They have reached the point where they need to win over public opinion to confront them.

Science and technology are not as good as literary works, relying on a sentence I feel that I love to eat, you may also love to eat, you can do whatever you want to hold something up to the sky or spray it into a dog, although science and technology backward can be packaged as more advanced to a certain extent, but advanced things are said to be backward, hard numbers and data can not deceive people.

took out a slender and slender lady's cigarette from the seven-star cigarette box in his hand, and with a crisp snapping sound, a faint white mist rose from Lu Zijiao's eyes.

Lu Zijiao, who was wantonly letting go of herself because of Kavin, looked at the faint smoke rising in front of her, and saw the mixture of sweat and steam that was blocked in front of her eyes when she was young when she was young when she was collecting firewood early in the morning and cooking breakfast for the whole family with a big stove.

"Lu Zijiao, don't touch my class notes in the future, you can't touch a black mark. ”

"You are talking nonsense, how can you have black hands when cooking, what about your soap, what about your liquefied gas tank. ”

"Whoa, wood-burning black-handed girl. ”

Lu Zijiao has five younger sisters and a younger brother, as the eldest child in the family, he has been used as half an adult since he was seven years old, and he has walked unscrupulously from the poor inland countryside to the prosperous international Hong Kong Island, which can be called sweat and tears all the way.

A cigarette was almost finished, and Lu Zi froze on the spot, the hardships of his childhood were like a lightning bolt slashing through the empty mind, and indescribable chemical changes occurred, and the dry inspiration rose like a tide.

Since the black-handed poor girl who burned firewood back then didn't know what a liquefied gas tank was, those poor ghosts on Hong Kong Island were equipped to use liquefied natural gas to generate electricity?

Technology and Civilization.

It has been more than a year since the Chernobyl nuclear power plant accident was first exposed by the Hong Kong Island media, and in the past year, this campaign initiated by the Hong Kong Island media has spread all over the world, arousing the attention of the global public to nuclear energy and nuclear safety~~ Balabala.

Lu Zijiao used her pen like a fly, and after setting the title of the article, she quickly wrote a series of words on the straw paper.

Although the Chernobyl accident was a big bomb detonated by the chief commentator of "Hong Kong Island Daily" ~ United Photon classmates, and other Hong Kong Island media followed up and reprinted it, and most of the attention was paid to Daya Bay, but the Hong Kong Island media still regarded this incident that affected the global nuclear energy development prospects and reshaped the concept of nuclear safety as the pride of the Hong Kong Island media community.

In addition to the influence of a certain behind-the-scenes mastermind, the media on Hong Kong Island, intentionally or unintentionally, always talk about this environmental protection light that has affected the world, which is also one of the important reasons.

Lu Zijiao started with this matter, and for the citizens of Hong Kong Island, the attention can barely increase by 10 percent.

After the Chernobyl incident, in order to have a deeper understanding of the development and future of the energy industry, our reporter visited Professor Wang Zhongshi of the Department of Social Economy of the University of Hong Kong many times.

Most of the journalists are from the liberal arts, and of course some experts have to be recruited to endorse them in order to ensure persuasiveness, but although the modern discipline is becoming more and more professional, there are more and more intersecting situations, and the power generation thing can be closely linked to at least ten fields, and it is worth thinking about which experts to choose.

The project of a simple power plant can be interpreted from a professional perspective, a technical perspective, a social perspective, an environmental protection perspective, a cost perspective and countless other directions, and the interpretation of each angle will be different.

Lu Zijiao talked about her childhood cooking stove again, but it didn't sell badly, but made the matter of firewood idyll, and then from the perspective of man and nature, it was concluded that firewood is the most harmonious way to use energy, of course, it also shows that firewood is the least costly energy use method in economics, almost no money.

Starting from firewood, which is an energy source, slowly moving on to coal, oil, natural gas, and nuclear energy, the cost is getting higher and higher, and the machines are becoming more and more complex, and the harm is getting bigger and bigger.

For example, firewood and coal only have fire, oil has the danger of explosion in addition to fire, natural gas is a very explosive energy source and combustion is also toxic, not to mention nuclear energy, fire, explosion, plus nuclear radiation.

Through the eloquent text inducement, Lu Zijiao blackened the power generation methods other than coal-fired thermal power, and defined coal-fired power generation as the only way to obtain electricity in the three major fields of price, environmental protection and safety.

Finally, Lu Zijiao also made a qualitative description of natural gas power generation, although natural gas power generation is good, it also represents the future, but the technology is not mature and the cost is too high, which will raise the comprehensive cost of people's life and business development, not to mention that even the United States, which is the most technologically developed at present, has not done this, and the proportion of thermal power generation in North America is as high as more than 80, which is obviously doubtful about the safety of natural gas.

We are not guinea pigs, we are not testing fields, and cosmopolitan Freeport residents choose only safe and proven technologies.

Let's embrace a new way of delivering electricity in the next century.

Lu Zijiao's advertorial ends like this.

"Ahhh ”

The beauty of the young lady of Hanfu in Hucheng directly led to a certain acidity that lasted for a long time, and recently, the two girls always joked about Liang Yuan's sentence about looking at my country and sleeping or something.

Generally, when encountering this situation, Liang Yuan wilted silently, and then put on a disdainful posture of a good man not fighting with a woman.

"Pig head, show you, I'm so angry, this broken article is full of mistakes, how much wine did the editor-in-chief of Sing Tao Daily drink to put this thing on, this mother~~uh~ Color, as soon as the upper lip touches the lower lip, she directly throws our natural gas power generation into the next century, does she think she is the Lafayette who brought disaster to the country and the people?"

Since last week, some popular science and discussions on the energy field have begun to appear in the media circles on Hong Kong Island, although the angles are different, but the final conclusion is without exception, thermal power is the best choice for power generation on Hong Kong Island this century.

"Pig head, show it to you, and then help me blow a wave of natural gas power generation after reading it, so that I can balance my mood. ”

Ning Wanfei threw the new issue of "Sing Tao Daily" on Liang Yuan's desk.

The two girls have been completely distorted by Liang Yuan, some messy hot words are used more frequently than Liang Yuan, if you meet a crossing lurking now, you must treat the two girls as shining protagonists, and Liang Yuan as an ignorant local native.

"Let me take a look at the posture level of Sing Tao Daily. ”

Hearing that Liang Yuan's words and pronunciation were a little different, Ning Wanfei glanced at Liang Yuan, gently brushed her toes, and sat on the armrest of Liang Yuan's boss chair with her small waist twisted.

"Oh, even the gold medal commentator Zi Yu has been dispatched?"

Since the Hong Kong Island Daily's United Photon stabbed the Chernobyl nuclear power plant accident as its chief commentator, other Hong Kong Island newspapers have also learned this way of running gold medal commentators as a team.

The so-called gold medal commentator is a bit similar to the overseas famous column, but it is a team operation, the main characteristics are sharp language, clear views, focus on social explosions, interpretation angles or ass directions are also varied, how to shock, not limited to the traditional left and right three positions.

Liang Yuan used part of the methods of the later forum for spraying and the UC shock department in the operation of the newspaper, and the effect was surprisingly good, and then it was decisively plagiarized by his peers.
