Chapter 356: Both
"No, no, no, the U.S. Navy has set this technology as a must-have for the next generation of marine gas turbines, but that doesn't mean that it will be difficult for us to develop intercooled and reheated gas turbines, these are two completely different concepts. ”
Since I have made up my mind to come back this time to propose the launch of the intercooling and reheating gas turbine project, of course, it has been fully investigated before, otherwise how can we come up with a reliable plan.
In fact, as early as 1946, Rolls-Royce signed a contract with the British Navy to produce the RM60 gas turbine for marine intercooled reheating and reheating, and the requirement at that time was that the engine had a low fuel consumption rate across the entire power range. ”
I have to admit that sure enough, this Brit still likes to engage in all kinds of black technology, and the development of cold and hot in the development of World War II has just ended, awesome!
But .....
"As early as 1946, I began to study the technology of medium cooling and reheating, and it seems that the British are very far-sighted, but they have not been able to put it into practical use until now, and I am afraid that it will end in failure, right?"
The development of failed products, of course, does not have much reference significance, at most it can be regarded as verifying the theoretical feasibility of the technical route.
"Yes, in a sense, it did fail, because it did not fully meet the requirements of the British Navy. ”
To demonstrate that the intercooling reheating gas turbine power generation technology can be launched at present, Chief Engineer Wu does not mind pressing the intercooling reheating technology first, but in the end, it must be to the point.
However, we should look at these issues dialectically, and in 1954, the RM-60 was tested on the gunboat "Gray Goose", and the results showed that the engine met the design requirements, the fuel consumption rate was effectively controlled, and the thermal efficiency was greatly improved. The reason why it was not successful is that the engine has a high purchase cost and a large volume, and there is gas soot deposition in the heat exchanger, which reduces the efficiency of the heat recovery, but do these problems have an impact on our civil power station?"
Smiling, Mr. Wu looked ahead, he is now very confident in the intercooling and heating technology of civil gas turbines, although it seems very difficult, but it is not difficult to implement.
Wang Zhengguo kept bowing his head and thinking, as Fang Cai said, the problems encountered by Rolls-Royce in the RM-60 engine back then and the practical application of the technology in the civilian field are indeed not a big problem, or even completely acceptable.
"It doesn't hurt to increase the cost of the engine, as long as its fuel consumption rate can be reduced, and the future of large-scale production of engines should gradually reduce the cost. ”
Now that they have figured out the joints, there is no need for Chief Engineer Wu to let Wang Zhengguo continue to guess.
"You're right, the cost can be reduced, and we are a power station built on land, so the size is completely acceptable; as for gas soot deposition, that's a problem only for oil engines, we only produce water and carbon dioxide when we burn natural gas, and there is no soot, and with the current gas turbine technology, even if we burn fuel, there will be no soot. ”
Only after in-depth research on this project can it be possible to come to such a conclusion, so Chief Engineer Wu is really talented!
After a long time, Wang Zhengguo gradually reacted, maybe this time he can really start to launch the intercooling and reheating technology, so as to solve the shortcomings of the combined cycle technology.
As for the benefits of intercooling recuperation technology at this time, it is needless to say that it can be ahead of the United States and Britain and other traditional gas turbine powers of large-scale intercooling recuperation technology, although it is only a civilian technology, but it can bring benefits is difficult to estimate.
As long as there are no major problems in the follow-up, the Republic Navy will be able to have the opportunity to use high-performance intercooled reheating gas turbines ahead of Britain and the United States.
Making so many articles around a Spey engine and making continuous improvements, it will inevitably develop a huge family branch and become a J-7 fighter in the field of aero engines.
"Okay, then we'll get on this medium-cold and hot up, about technical issues, since Rolls-Royce developed a semi-finished product like RM-60 back then, now with the relationship between our two companies, we should be able to buy a full set of design materials for a little money, after all, that thing is not mature in terms of shipbuilding, and we buy it back just for a reference." ”
The Republic has never studied the technology of intercooling and reheating, and now it is necessary to suddenly prepare for the launch of this technology, and to complete the development work in a short time, and to introduce external technology as a reference.
"That's what I mean at the moment, I happened to have preliminary contact with that side before returning home, and as long as 500,000 pounds sterling, they will give us a copy of all the materials, they don't attach too much importance to this thing, and now all their energy is invested in the research and development contract awarded by the US Navy. ”
That is to say, at present, no energy equipment giants have proposed distributed power station plans, and they are still deeply engaged in the field of centralized large-scale power station equipment, and the so-called gas turbine power generation is still based on heavy-duty gas turbines as the main breakthrough direction.
The heavy-duty gas turbine market that was initially formed in the 80s is a typical sunrise industry, which is mainly dominated by the 31-105M E-class gas turbine at this time, the F-class gas turbine that developed to 125-335M in the 90s, and the 400-520M H/J class gas turbine began to appear in the second decade of the new century.
In fact, it is not difficult to see that heavy-duty gas turbines are in full swing at this time, and in terms of power, they are constantly increasing, and who would have thought of doing the opposite and engaging in distributed gas turbine projects?
It is only in the special situation of Sichuan Province, the time, location, people and all of them are all outside the column to point to the demand for distributed gas turbine power generation, so this is destined to Southwest Motor to become a generation of energy power machinery giants, to be able to achieve technological leadership in a field, with enough confidence and then horizontal breakthrough, it will naturally be easier.
When there is time in the 90s, let alone the development of heavy-duty gas turbines, at that time there will be great advantages in technology and capital, so as not to be smeared.
"We will definitely establish a project to develop intercooling and reheating technology, which will indeed have great advantages for some areas where logistics and maintenance are not very convenient or there is a shortage of water, but this is definitely not a reason for us to give up the joint technology of combustion and steaming. ”
For the steaming alliance, Wang Zhengguo must be promoted, and there is no room for negotiation.
"The combination of fuel and steam is not only developed for our current distributed generation technology, it is also an indispensable technology for us to enter the field of heavy-duty gas turbine power generation in the future. Taking another 10,000 steps back, or in the field of distributed power generation, the combined heat and power scheme proposed for the winter urban heating problem in the northern region also needs to be improved on the basis of the distributed combustion and steaming unit, so this cannot be abandoned. ”
All in all, around the field of gas turbine power generation, it is now necessary to maintain sufficient investment in the two programs of "intercooling and reheating" and "combustion and steaming" at the same time, after all, this is also essential to appease the Dongfang Boiler Plant under the complete set of equipment of the Dongfang Power Station.
