Chapter 900: The Beginning of the Rise
Anyway, Yang Hui only knew that several large oil and gas fields had been discovered in the Tarim Basin at this time, and the hat of a gas-poor country in terms of natural gas in the Republic could finally be thrown off, and the corresponding development and utilization of oil and gas resources must also be taken into account. Pen, fun, and www.biquge.info
However, before the state proposed the West-East Gas Transmission Project in 2002 and started the entire project in 2007, these natural gas resources could only be used in the new project. Xinjiang local digestion and new. As a place where heavy industry is not very developed at this time, the development and utilization of natural gas is mainly based on power generation.
As a relatively concentrated province in the nineties, the new . In terms of electricity consumption in Xinjiang, it is actually the same as in the Central Plains, which is difficult to open up to you, so with the discovery of a large number of local natural gas resources, the construction of natural gas-fueled fuel-steam cycle power plants, this has room for development.
Therefore, at this time, although the government has not fully lifted the ban on oil/gas power generation, it can be said that these equipment are based on foreign markets and will not be sold in China for the time being. Xinjiang needs power generation, and at this time, I am afraid that not many people will think that the 420 factory intends to use this as a breakthrough point.
That is to say, in addition to Xiang Qiao, the director of the 420 factory who has hollowed out his mind to develop the combustion-steam cycle power generation technology, he can't wait to study and sell the steam engine technology as soon as he sees that a large-scale oil and gas reserve area has been discovered in China.
"In recent years, China has explored a large natural gas storage area, and now I have made many contacts with domestic natural gas exploitation units and power units, and they are also very interested in natural gas-fueled fueled fuel-fueled fueling fuel-steaming cycle power generation technology, and even in the southwest hinterland where we are now, several high-quality natural gas reservoirs have also been discovered. We are seeking a tripartite contract to first secure an experimental gas-fired cycle power plant in our Bashu hinterland by the year 2000. ”
Since it has been decided to build a power plant fueled by natural gas, it is necessary to have a thorough understanding of the exploration and exploitation trends of various natural gas resources, and only in this way can we grasp the use of equipment and first-hand information of potential customers at the first time.
It is for this reason, coupled with Xiang Qiao's investigation of power plants in coastal areas where electricity consumption is larger, that she clearly knows that in order to promote the combined fuel-steam generation technology in the Republic in a large number of times, the source of natural gas in the coastal areas is indispensable, and she is also heartbroken for this.
Xiang Qiao's idea can be regarded as tapping the potential of the combined technology: "But then again, the reason why we are interested in the Dawn-machine design complex in Ukraine is not only because their combined cycle technology can be used in our civil power generation field, but even because we are ready to transform and develop this technology accordingly, so that it can continue to exist as a power system on ships." ”
After all, the current 420 factory can also be regarded as a power supply unit for naval ships, since it has finally entered this field, it is even more necessary to grasp this last military power system business, and it must not be relaxed.
Although the technology of the 420 plant to make a fortune in the future is determined to spend time in the civil field, in order to make a complete set of power generation equipment provider, it is not only necessary to have a high-power heavy-duty gas turbine, but also a low-power aeroderivative gas turbine as a power plant peak shaving is also a must-have.
Therefore, the future 420 plant will not, nor can it give up the field of aeroderivative gas turbines, and since it wants to leave the aeroderivative gas turbine business below 50MW, the power system of military ships also needs to continue to pay attention to it.
Therefore, Yang Hui is very recognized for the pursuit of 420 factory in the marine gas turbine market: "This is not wrong, in the foreseeable future, the thermal efficiency of simple cycle gas turbines has developed to the end, but in the future under the continuous pursuit of improving the thermal efficiency of gas turbines, it is necessary to have new technologies invested in scientific research and manufacturing, which will eventually enable it to greatly reduce fuel consumption and costs, but this thing is to be used in warships, we still need more research and research." ”
In Xiang Qiao's view, the combined cycle of combustion and steaming is not that it cannot be used on large surface ships, the only problem is only the parallel problem between the gas turbine and the steamer, and at this time in the mid-90s, the concept of all-electric power system has attracted the attention of all parties, so the future surface ship power system of the 420 factory can continue to go on the route of the combined technology of combustion and steaming, anyway, with the introduction of electric propulsion technology into the warship, the gearbox will be directly canceled. The biggest problem that plagued the power system of the Glorious-class cruisers back then is no longer a problem.
First of all, it must be affirmed that the combined cycle technology of combustion and steam can be put on the warship, it is absolutely possible to achieve the highest thermal efficiency of 60%, you have to add the introduction of electric propulsion technology, the endurance of the ship will get a very large step, the problem of the gas turbine power system oil tiger that has been criticized can be significantly solved, the most conservative estimate, this technology should also be able to increase the range of the warship with the same oil reserves by at least 30%.
It's a pity that the volume of the combined power system is still a little too large, and the coexistence of two power systems of gas turbine and steam turbine will also lead to the power system of the entire warship becoming extremely complex, and the steam turbine also needs to consume a lot of fresh water, which is the weakness of the steam turbine.
Although the combination of combustion and steaming on the ship can be very effective to solve the problem of low thermal efficiency of simple cycle gas turbines, it also brings various inherent problems of steam turbines, so the design of this power system is not a good match for destroyers with every inch of land.
In contrast, in order to achieve higher thermal efficiency in the power system of large surface ships and ultimately achieve the goal of large-scale fuel savings, it is better for the Yankees to choose the intercooling and reheating technology. First of all, this thing is relatively compact and suitable for use on destroyers; The second is that it is still only a single gas turbine doing work, and while improving thermal efficiency, it will not introduce the shortcomings of steam turbines like the combination of combustion and steaming.
Therefore, Yang Hui himself is not very willing to support the use of the combined power system for destroyers and destroyers, and the only advantage of it is probably that it can produce a large amount of high-temperature steam, as long as this technology can be studied, it can be used in the power system of aircraft carriers.
First of all, the aircraft carrier can finally have the advantages of gas turbine rapid start, which even the ability of nuclear-powered aircraft carriers cannot have, and if you want to use gas turbines as power, the entire aircraft carrier fleet can say goodbye to heavy oil, and you can use aviation kerosene to provide fuel support for ships and aircraft, which will greatly simplify the difficulty of logistics support.
The exhaust gas boiler on the aircraft carrier is not used to provide power for the ship's propulsion system, it is specially designed to provide a large amount of high-temperature steam for the steam catapult, or it is intended to be used in the power generation system.
And such a combined fuel-steam power system should be the best power choice for conventional aircraft carriers, but in the end, what should be said, you can't say that this fire-steam combined warship is bad, nor can you say that it hangs everything, but it depends on what type of ship it corresponds to, and this is the most important point.
In the end, only one sentence remained: "This technology can still be studied carefully, although it is not suitable for use on destroyers, but it is combined with the localization of QC-280 gas turbines, and it can also be a good power option for conventionally powered aircraft carriers in the future.
