Traditional coal-fired power stations also use boilers to burn steam, but people take the centralized power generation scheme, and the logistics and maintenance can be managed in a unified manner, so of course they can accept that these are not problems.

The essence of distributed generation is to distribute smaller generator sets close to the power consumption site to meet the needs of specific users, which can reduce the problem of long-distance power transmission losses caused by the use of centralized power generation schemes.

To put it bluntly, it means that power companies build small power stations close to large electricity consumers, such as gas turbine research institutes, industrial parks, and near urban residential areas.

Distributed power stations can be supplied to the surrounding areas immediately after the direct power generation is completed in these places, effectively reducing transmission losses, and greatly improving the fault tolerance rate of the entire power grid and reducing the possibility of large-scale power outages.

At the dawn of the new century, gas turbines are the only energy sources that can be expected to replace coal-fired power generation on a large scale in the field of traditional thermal power generation.

For example, in the upper plane, until 07, the United States was a major coal-fired power generation, accounting for about 49% of the total power generation in the United States, and the total coal-fired power generation in the United States at that time was no different from the Republic, or even more.

After 07 years, the United States began to vigorously develop natural gas, shale gas as fuel gas turbine power generation technology, before and after less than two or three years, immediately to the United States power generation field to a big change, coal-fired power generation accounted for only about 30% of the total power generation.

Since then, the United States has the courage to start calling out the Republic, which is also a country dominated by coal-fired power generation, to start shouting about various environmental issues and demanding emission reductions.

But to put it practically, even if the cost of desulfurization, denitrification, dust removal and other expenses is added, the cost of coal-fired power generation in China can still be controlled between 0.25-0.45 yuan/kWh, and such a low price is second only to large hydropower stations.

Nuclear power, which has always been favored by many technical people, has an approved electricity price of 0.43 yuan/kWh, and as for the problem of nuclear waste, it seems that it is more difficult than thermal power.

Of course, if the Republic drastically reduces the proportion of coal-fired thermal power, this may reduce pollution a little, but the pollution of large-scale thermal power is actually very small.

As for shutting down thermal power to reduce a lot of carbon emissions (carbon dioxide is not a pollutant, it is a greenhouse gas), it depends first of all on whether you believe that carbon emissions will lead to global climate change, which is a deadly threat.

For example, if you put yourself in the shoes of scientists who study the ice age, a large amount of carbon dioxide is emitted, and it may be a good thing to delay the arrival of the ice age.

Let's get back to distributed gas turbine power generation projects.

In fact, in terms of the natural gas reserves of the Republic, there is absolutely no problem in supporting the gas turbine power generation industry, and the actual power generation cost of a province like Sichuan Province, which is rich in natural gas resources but has very average coal reserves, will certainly not be higher than that of coal-fired power generation.

If you study carefully, you will find that the energy distribution of the entire Sichuan-Shu region is very interesting, coal is concentrated in the Panhua area of southern Sichuan, but the coal there is of high taste, mainly for steelmaking, and high-grade coal itself is also an important chemical raw material, it seems to be a pity to use it for coal-fired power generation.

Then in Sichuan Province, the natural gas resources with the largest reserves in the country, this thing is directly scattered in 12 urban areas of the province, and all of them are gas field gas, not oil field associated gas products, and most of them are shallow gas, which are easy to exploit.

Natural gas is abundant, but distributed throughout the province, and it would be a crime not to develop distributed gas turbine power generation technology fueled by natural gas.

"Nationwide, there is no province that is more suitable for the development of natural gas power generation technology than our Sichuan Province, so no matter which side you stand on, the distributed gas turbine technology that uses natural gas power generation must not be changed. ”

Wang Zhengguo's words are very certain, and the matter is related to whether his larger plan for the future can be implemented, and it must not be changed.

"I fully understand that there will be no change in the gas turbine generation route, I am just against the joint gas-steam project, and in the distributed generation plan, simpler and more reliable maintenance must be required, so I propose to change to an intercooled reheating gas turbine scheme. ”

After all, it has been stationed in Rolls-Royce for several years, and there is still some research on the development direction of gas turbines in recent years.

Regarding the news he inquired about in the UK, Chief Engineer Wu directly told him that this was the fundamental reason why he advocated the introduction of cooling and heating technology.

In October 1985, the U.S. Navy signed two contracts with General Motors and Rolls-Royce of the United Kingdom to develop intercooled reheating gas turbines. ”

Wang Zhengguo has heard a lot of things in the upper plane, the most famous of which is the Type 45 destroyer used by the British Navy for the top ball, using the R-21 gas turbine, which is the top marine gas turbine using intercooling and reheating technology.

Now Chief Engineer Wu Daguan is directly going to get on the horse to cool and heat up, how can this not be surprising, but he clearly knows that the Type 45 is because the R-21 engine is too advanced and the technology is not reliable enough, which eventually leads to a comprehensive nest.

Think of an aging Lafayette in the British Empire, a son who has been waiting to succeed him for many years, a plasterer's nave in the hall, an empire in decline, a declining navy, an Oriental empire clamoring for railroad construction, a group of wolves and tigers, a group of rebels who have been divided all day long......

Today's foreigners are fortunate to be in Windsor, tomorrow are fortunate in London, and when will they be fortunate in New York?

Naizu abandoned America, Nai Weng abandoned Tianzhu, and now abandon Scotland, the sun does not set on the territory of the country, every time there is no longevity!!

The tragedy of the Oriental people is really sad for those who hear it, and tears for those who hear it.

However, my British country has its own national conditions here, and it has always been a country that has been majestic in the world, and it is necessary to subdue people from afar with virtue, destroyers or something......

Therefore, even an old engine giant like Rolls-Royce cannot fully guarantee the reliability of intercooling and heating technology in the new century.

First of all, it is necessary to affirm the sensitivity of Chief Engineer Wu in cutting-edge technology, to be able to see the superiority of intercooling and reheating technology in the eighties, and to advocate the launch of the technical program, as a technical consultant, the ability to set the general direction of scientific research and technology is very accurate.

"Medium cooling and heating? I mean that the US Navy has just begun to carry out pre-research on it and position it as the next generation of marine gas turbine technology, then I am afraid that the difficulty of this technology is not low, and with our current technical level, I am afraid it will be difficult to make a breakthrough in a short period of time, right?"

The inability to make a technological breakthrough in a short period of time means that the project cannot be put into practical use, and compared with the relatively mature combustion and steaming combination of the technology, the development cycle of the two is indeed too different, and it is obviously not suitable to start the cold and heat up now.

At present, Sichuan Province is in urgent need of solving the problem of lack of power generation and meeting the electricity demand of the science and technology industry in the high-tech zone, which is already an urgent matter.
