The energy industry has always been the most important industry involving the national economy and people's livelihood, and being able to control the distribution of energy has always been a kind of jealousy and jealousy, because this is definitely a very lucrative industry.

But! The reason why energy can be called energy is because the technical level at that time can ensure that resources can be extracted and used, and only the kind of energy that can be extracted can be officially called energy.

For example, when petroleum resources are developed, this can be called energy, and when people can't refine oil, who will think that it is energy? It is also after solving the large-scale power generation and long-distance transmission technology that electricity can be called energy.

Correspondingly, other so-called future energy and nuclear fusion clouds, although they are also directly named as energy, but before the stable development and utilization of nuclear fusion energy, this nuclear fusion energy can only be seen from afar, and this has also caused various countries that are interested in this to continue to invest in nuclear fusion energy.

Therefore, the reason why energy is called energy is because there is enough technology to complete its development and use, and the kind of "energy" that is not developed and used by enough technology will definitely not have the possibility of large-scale development and use, and will naturally not cause large-scale competition.

The energy industry is indeed quite important, which is almost one of the important factors for whether a country can ensure long-term peace and stability, and in fact it is more important than the energy industry, that is, the mastery and use of energy exploitation technology, which is extended to the power industry, refers to the development and mastery of large-scale and high-efficiency power generation equipment.

As far as the future of large-scale power generation equipment is concerned, gas turbines are of course the top priority, and the road to large-scale power generation equipment R&D and manufacturing determined by the 420 plant is definitely correct, but the development of large-scale power equipment needs to be supported by sufficient advanced technology.

Or to put it another way: in the R&D and manufacturing industry of energy extraction equipment, all competitiveness lies in the leading position in mining efficiency, and this mining efficiency also means the introduction of various new technologies.

Gas-steam combined cycle, this is the only magic weapon for heavy-duty gas turbine power generation equipment to improve power generation efficiency, and now the technical route proposed by the 420 plant is not not advanced, Yang Hui admits that this is indeed a very far-sighted technical design route, but this guy needs to use gas turbines, steam turbine power generation two technologies, the actual operation is indeed very difficult.

"Gas-steam combined cycle power generation technology is indeed very thoughtful, for example, let's just talk about gas turbine technology, I think your 420 plant itself should be able to complete the relevant technical research, but the development of steam turbines still needs to be considered in many aspects. You can't design the gas turbine of the 420 factory with first-class performance, but the supporting steam turbine is dragging its feet, so in this regard, it is not unreasonable for you to want to merge with the Dongfang Steam Turbine Plant, but it is definitely not enough to want to annex Dongqi for this reason alone. ”

In terms of steam turbine manufacturing technology, Dongfang Steam Turbine Plant is indeed very strong, but their strength is based on coal-fired boiler-steam turbine technology, while the supporting technology used by gas-steam turbine cycle generator sets is: exhaust gas boiler-steam turbine system, there is actually a very big difference between the above.

In order to understand the various ways here, we must first explain the working principle of the gas-steam cycle generator set.

First of all, the use of heavy-duty gas turbines for power generation is the main source of power generation, which mainly relies on the fuel of gas turbines to produce high-temperature gas and then do work to generate electricity, which can convert a part of the thermal energy into high-grade electricity.

However, the power generation efficiency of a single gas turbine is not high, and there is a very large waste, and these wastes are mainly reflected in the fact that most of the energy generated by the fuel is turned into the heat energy of high-temperature gas, and these heat energy is difficult to play a role in the gas turbine, and can only be discharged into the atmosphere in the end.

Now the question is, since the high-temperature gas after the first generation of the gas turbine still contains a lot of energy, is there any way to solve this part of the waste, really cool the high-temperature gas, and also effectively use the remaining heat energy, so as to improve the efficiency of the generator set?

The answer is: Yes!

Since the heavy-duty gas turbine will eventually discharge a high temperature of about 600 degrees Celsius, then make good use of this high temperature, install a boiler on the exhaust gas exhaust channel of the gas turbine, you can use the gas waste heat discharged by the gas turbine, after generating a large amount of steam in the boiler, you can use the high-temperature steam to drive the further power generation of the steam turbine, and at the same time, you can also cool the high-temperature gas emitted by the gas turbine.

Therefore, in the technology required for the gas-steam cycle generator set, the breakthrough is actually only the manufacturing technology of the exhaust gas boiler, so take a step back and say: the steam turbine used in the gas-steam cycle generator set. There is not much technical difference between it and the old coal-fired boiler-steam turbine.

Even if you want to directly use the steam turbine in the coal-fired boiler-steam turbine technology, it can work, and then you can directly use the steam turbine in domestic production, which does not require much technical improvement, and can be put into use directly.

Speaking of which, the steam turbine used in this gas-steam cycle generator set uses a waste pot to produce steam, and this exhaust gas boiler is the most important thing.

Now seeing that General Manager Yang directly denied the efforts of the 420 factory to develop in the direction of steam turbines, Xiang Qiao could only retreat at this time.

"Alright! We can give up the development of steam turbines, and then directly bid for the mature products of the three major domestic steam turbine factories, but we have no foundation for the development of exhaust gas boilers in China, so the most important new technology waste gas boiler in the gas-steam combined cycle generator set can only be developed by our 420 factory itself, and to say that the source of this technology, we have aimed at the Ukrainian side, and now Ukraine's technology in this area is world-class.
