Chapter 898 Historical Moments
The MT-30 gas turbine developed in the UK can also reach a power of 36 megawatts.

But whether it is for the UK's own use, it is installed on their Queen Elizabeth-class aircraft carrier.

It is still exported to the United States and installed on the "Independence-class" littoral combat ship and "Zumwalt-class" destroyer.

The MT-30 gas turbine is a whole bunch of problems.

This gas turbine was improved from Rolls-Royce's "Rida-800", which is a three-rotor aeroengine.

In contrast, the "HLJ" gas turbine was improved from the "Haihe" small bypass ratio aeroengine.

"Haihe" is the same as the F-110 aeroengine, it is a twin-rotor aeroengine.

The LM-110 gas turbine derived from the F-2500 is known for its maturity and reliability.

As for machinery, the simpler the structure, the higher the reliability.

"HLJ" also verified the feasibility of Dongsheng Heavy Industry's 100% hydrogen combustion technology solution.

The biggest problem with clean energy is that it is not stable enough.

Needless to say, wind energy comes and goes.

Solar energy is surplus during the day and completely absent at night.

There are many solutions proposed, but the difficulty of implementation is quite large.

For example, one of the solutions is to use excess solar energy to electrolyze water during the day to produce "green hydrogen"-compared to "grey hydrogen" produced by coal and natural gas.

Store it up and burn hydrogen to generate electricity at night.

Achieving true zero emissions!

The idea is good, but it is difficult to actually implement it.

The combustion temperature of hydrogen is too high - it can even reach more than 3000 degrees.

After the combustion temperature is higher than 1500 degrees, the oxygen and nitrogen in the air will react to produce nitrogen oxides, such as nitric oxide, nitrogen dioxide, nitrous oxide, etc.

And every time the temperature increases by 100 degrees, the content of nitrogen oxides will increase by 6 to 7 times.

Nitrogen oxides are toxic to varying degrees, and can cause bronchitis or emphysema after entering the human body.

It is also one of the reasons for photochemical smog pollution, acid rain and ozone reduction.

At present, the world's mainstream manufacturers of aero engines and gas turbines use lean fuel premixed combustion as the main way to solve nitrogen oxide pollution.

However, premixed combustion technology faces the risks of spontaneous combustion and flashback.

And when the temperature is higher than 1700 degrees, it is difficult for the premixed combustion technology to meet the emission requirements.

At present, countries can only achieve hydrogen-doped combustion on heavy-duty gas turbines, and the maximum can only be about 15%.

Not to mention the small gas turbines used on ships!
Dongsheng Heavy Industry did not take the technical route of premixed combustion, they adopted another solution.

The principle is very simple.

When the temperature is higher than 150 degrees Celsius, nitrogen dioxide begins to decompose.

When it reaches 650 degrees, it will be completely decomposed into nitric oxide and oxygen.

When nitric oxide is heated to 700 degrees, it will decompose into completely harmless nitrogen and oxygen, and it will decompose violently at 1200 degrees.

In other words, as long as the temperature of the gas turbine exhaust is controlled between 1200 and 1500 degrees Celsius.

It can quickly decompose nitrogen oxides, thereby reducing emissions.

The "HLJ" aeroderivative gas turbine verified the feasibility of their idea, and the effect is very good.

The concentration of nitrogen oxide emissions can be reduced to 35 mg per standard cubic meter.

Not only is it lower than the "Marine Engine Exhaust Pollutant Emission Limits", it is even lower than the national standard of 50 mg of nitrogen oxides per cubic meter for gas-fired power plants.

Paved the way for their heavy-duty gas turbine R&D efforts.

Back home, when eating, the little tiger still gobbled it up.

That posture was almost like a fight.

But a little strange, her double chin seems to be gone.

Zhou Ying also felt strange, "A dead girl is a thief, she didn't eat less, but lost weight instead!"

Time entered May, and South Asia, which had been quiet for more than half a year, became lively again.

The local faction of Meng Xing reached a temporary compromise with the central faction of Xin Xing who fled to the past.

The Northern Democratic Alliance in New XX has also regrouped.

The two sides fought again.

This time the war was particularly fierce, and it was backed by major powers.

Although the Northern Democratic Alliance still suffers from the sea and air force, but with a sound air defense system, it will no longer allow others to fly overhead and drop bombs.

Moreover, their coordination and command system have been qualitatively improved.

The South has also received sufficient ammunition, and their army has been retrained by a certain country, and their combat effectiveness has been greatly improved.

The armed forces supported by Yang Dongsheng are also actively buying ammunition.

But the house leak happened to rain overnight, and one of their transport planes crashed in South Asia.

Not only the aircraft and munitions were destroyed, but all the crew members were killed.

The lions on the Russian side opened their mouths. An old Il-76 that has been used for an unknown number of years actually asked them to pay 6000 million U.S. dollars in compensation, and each crew member paid 100 million U.S. dollars in compensation.

Although it's a bit dark, Yang Dongsheng can only recognize it.

Just after losing money here, Dongsheng Foods reported that they had received a big deal—Tibetan Province will buy 100 million tons of grain from them this year and next two years.

"It's lively now!" Yang Dongsheng said.

50 tons of grain is enough to feed 100 million people for a year.

The meaning here couldn't be more clear.

No matter what his considerations were, Yang Dongsheng would not refuse this big deal. After signing the contract, he flew directly to Qing Province to witness this historical event.

……

The formerly desolate Qaidam Basin now looks like a paradise on earth.

As the weather gets warmer, many people travel by car.

From time to time, some people simply park their cars on the side of the road and take pictures with their cameras.

Yang Dongsheng was not in the mood to look at these scenery, and the car came all the way to a small town.

Here stands a huge granary.

After Yang Dongsheng got off the car, he rushed directly to the warehouse.

A young man in his thirties trotted forward after hearing the news, "Mr. Yang!"

"How's it going?" Yang Dongsheng asked.

"20 cars have been loaded!"

The Qinghai-Tibet Plateau has a high altitude, and the engines of these trucks are specially modified.

After the grain was loaded onto the truck, it was directly transported to the train station tens of kilometers away.

The vicinity of the train station has been strictly guarded.

It was only after learning that they were transporting grain to Tibet and showing relevant documents that they were allowed to go.

As soon as the convoy entered the station, a series of trains drove past without stopping.

Although everything on the car was covered with canvas, the general outline under the canvas and the dark muzzle could still be seen.

A railway worker next to him asked his companion, "Which one is this, are you going to fight?"

"Even if we shoot, the shells won't fall on our heads!" said the companion.

Ordinary civilian planes are no longer allowed to fly to Tibet. Yang Dongsheng came to Saskatchewan with the grain truck.

Compared with Qing Province, the atmosphere in Saskatchewan is much more serious.

Not to mention the vehicles passing by on the street, hospitals at all levels have been recruited temporarily, and air defense positions have been set up on several high grounds around Saskatchewan.

After delivering the first batch of grain, Yang Dongsheng went to visit the employees of Dongsheng Mining.

For safety reasons, evacuation orders have been implemented at all mines.
