The development of energy is always a topic that is difficult to avoid, and the ability to make the 420 plant full of energy to go to the road of heavy-duty fuel-steam combined cycle generator sets is the best choice for the future of the 420 plant, and it is also the only way to go and can go in the 420 factory, in addition to this, Yang Hui really can't think of other options for the future of the 420 plant. Pen "Fun" Pavilion www.biquge.info

For the time being, let's not talk about the general manager of United Aero Engine Company, first plan the future of the 420 plant, which is the most important thing: "It is indeed very promising to enter the field of large-scale complete power generation equipment manufacturing, and there is a large number of technologies from the head office as the backing support, I believe that with the technology of the 420 plant, coupled with the influence of Academician Wu Zhonghua in the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, there will be no problem to complete the development of heavy-duty gas turbines. The difference is only in which class of heavy-duty gas turbine is being developed, whether to choose the B/C, E/F, or G/H supergiants. ”

With the technical capabilities of the 420 factory, the most common and mainstream technology in the world is the E/F heavy gas turbine, that is, the 100-200MW heavy gas turbine, and at this time, the domestic technology will support the development of the E/F class gas turbine at most, and also in the nineties, the most common and mainstream technology in the world is also the E/F class heavy gas turbine.

In the early 80s to mid-90s, it is the technical development and maturity period of E-class heavy-duty gas turbines, the power of the E-class basic model launched in the early 80s is between 31-105MW, the gas temperature reaches 1100C, and the thermal efficiency is about 30% under single-cycle conditions, until the mid-1990s, the power of the single engine increases to 37-130MW, the gas temperature reaches 1200C, and the efficiency is about 32%. At this time, the E-class heavy-duty gas turbine became the mainstream product in the global heavy-duty gas turbine market.

Compared with the international development of heavy-duty gas turbines from the 80s to the early 90s, domestic counterparts have suffered heavy casualties.

During the period from 1980 to 2000, due to the severe shortage of oil and gas supply across the country, a document was issued directly at the national level requiring that the use of oil/gas as power generation fuel was not allowed.

In addition to retaining a heavy-duty gas turbine manufacturing plant in Jinling Steam Turbine Factory, other manufacturing enterprises have all withdrawn from the industry, personnel and technology have been rapidly lost, the gas turbine major of the university has been changed, personnel training and national R&D investment have basically stopped, and the gap between domestic and international levels has widened rapidly.

In the previous face has to wait until 2002, with the discovery of a large number of natural gas resources in the western region, the increase of west-to-east gas transmission and imported liquefied natural gas (LNG), the domestic and ignited the large-scale demand of the heavy-duty gas turbine market, through the introduction of foreign advanced F/E heavy-duty gas turbine manufacturing technology, successfully realized the localization of manufacturing, to meet the needs of the power industry, by the end of 2013, the national heavy-duty gas turbine power station installed capacity of more than 34,000MW, It accounts for about 3% of the country's total installed power generation capacity.

In the new century, through technology bundling bidding, we took this opportunity to introduce the technology of the three giants into the three domestic units of Shangqi, Harbin Gas and Donggas, and the heavy-duty gas turbine was once again flourishing in the Republic.

But this kind of propaganda mouth, if you really believe it, you will lose, the republic after 2000 is a is about to be pulled out of the hurry to dig a pit, the foreign three of course see the urgent need of the republic, so it is symbolic to put some gas turbine cold end parts manufacturing work in the republic, and claim that the whole set of equipment in the republic to achieve a localization rate of more than 50%, is definitely a conscientious manufacturer.

The three foreign giants still retain the core gas turbine control system, the manufacturing of the core components of the hot end, and what is even more frustrating is that the three giants are the follow-up maintenance of the unit, and the maintenance of the follow-up equipment is an important source of profit for large-scale complete sets of industrial equipment.

It can be said unceremoniously that although the domestic after 2000 claims to have achieved more than 50% of the localization of heavy-duty gas turbines, the localization of 50% is just a coolie worker, and the most core and profitable part will never be in the hands of domestic manufacturers.

If you really want to achieve a lot of profits, you still have to have independent intellectual property rights to work, now the 420 plant still has the opportunity to borrow the international heavy-duty gas turbine is only in the E/F class when the force, it is still possible to catch up, only need to take about ten years to complete the development of the whole set of gas-steaming combined cycle generator sets, almost even if the most difficult first stage of the goal has been completed.

It is indeed a sad fact to say that the country abandoned its martial arts in the 80s and gave up the sustainable development of the heavy-duty gas turbine technology route, after all, the heavy-duty gas turbine industry of the Republic was established in the 50s, and it was not too late to start compared with developed countries, even earlier than the Mitsubishi Heavy Industries gas turbine development business, one of the three giants of international heavy-duty gas turbines.

That is, in the early stage of 1950-1970, China realized the independent design, testing and manufacture of gas turbines on the basis of digesting and absorbing the technology of the former Soviet Union, and developed a variety of types of gas turbines, including on-board gas turbines, locomotive gas turbines and heavy-duty gas turbines, etc., and cultivated the domestic first-generation gas turbine core technology independent research and development, experimental research, product manufacturing and engineering service technical team, and the technical level of the whole industry has made significant progress.

Then it was delayed for ten years during the Great Revolution, and at the end of the Revolution, it was directly cut down by Ziyang Zhenren with tears, which was attributed to the above, and it was also said that it was caused by the lack of domestic oil and gas resources, and it did make some sense to say it, which must be admitted, and it was an afterthought that was separated from the actual domestic environment at that time, this Yang Hui could not do it.

But now that we know that the future heavy-duty gas turbine business will be re-established in the Republic, we must not be able to sit idly by and complete the development of the entire project in about ten years, which is also a relatively normal development cycle for a heavy-duty gas turbine.

At least the last domestic independent development of the R0110 heavy-duty gas turbine took a full 8 years, you want to say how high the technical level of the domestic heavy-duty gas turbine at that time, in fact, it is not necessarily higher than now, and even because of the emergence of the United Aero Engine Company on this plane, the Republic has more experience in the relevant technical fields.

"Just do a good job, although the domestic government still has no policy support for the development of heavy-duty gas turbine equipment, but according to the current speed of domestic economic development, the next ten years will be the time for the return of heavy-duty gas turbines. The government does not give any support, but the head office will give all kinds of support accordingly, technically, humanly, and even financially. (To be continued.) )
