The rise of nanometers

2010, February 28.

Lantern Festival.

Ning District, Weizhou Town in the central region of Wuzhong City.

Close to the provincial highway, there is the Weizhou coal gangue power plant invested by Huaneng Group in 2007. The power plant has recently entered trial operation.

Huaneng's Vice President Wang Shuo arrived at the Weizhou Coal Gangue Power Plant right after the Spring Festival and on the eighth day of the Lunar New Year. He was so anxious and concerned mainly because this power plant was very important and related to Huaneng Group's industrial upgrading strategy.

At his urging, Chang Fuguo was unable to come to Ning District for the time being because he was dealing with major car companies recently, so Du Jinhua could only come here.

Du Jinhua, who brought a large amount of equipment, arrived at Weizhou Coal Gangue Power Plant on the Lantern Festival.

The factory area is clearly divided into two large areas, one is the power plant area and the other is the gas refinery area.

Du Jinhua led the convoy into the gas refinery area.

Wang Shuo, who had been waiting for a long time, saw Du Jinhua get out of the car and immediately came up to say hello: "Mr. Du, long time no see."

Du Jinhua pointed at the fleet and said, "Mr. Wang, I have brought all the equipment. Now we can start installation and debugging."

"It won't be too late. The infrastructure inside the factory is ready, and the workshop has been laid out according to your design drawings."

Enter the factory interior of the factory area.

The engineers and technicians of Snail Industry began to arrange the equipment according to the planning and design plan. The design work here itself involved the participation of Snail Industry, and with the cooperation of the engineering team of Huaneng Group, the installation of the equipment was very fast.

The equipment of Snail Industry itself is of modular design. With complete infrastructure and supporting facilities, the equipment can be installed in less than four days.

The gas refinery has completed the equipment installation and entered the debugging stage.

At the same time, Du Jinhua led some engineers to install thermoelectric power generation modules. The gas turbine generator set of Weizhou Gangue Power Plant used General Electric's gas turbine, which was a helpless choice.

However, several newly renovated power plants have already planned to use Beifeng gas turbines. Now that the performance of Beifeng gas turbines has caught up, the five major power generation groups naturally have to take care of their own sons.

The thermal efficiency of these GE gas turbines is around 58%. After installing a thermoelectric power generation system, the overall thermal efficiency will increase by another 10% to an astonishing 68%.

It took 12 days to finally complete the new energy transformation of Weizhou coal gangue power plant.

Master control room.

Du Jinhua pushed the door open and walked in: "Mr. Wang, all equipment has been re-inspected and trial operation can begin."

"Thank you for your hard work, Mr. Du." Wang Shuo immediately ordered to start the trial run test.

In the two major plants of Weizhou Coal Gangue Power Plant, with the start of the trial operation test, trucks of coal gangue and washed coal were poured into the crusher. After preliminary crushing by the crusher, the gangue and washed coal became into coarse particles.

These finger-sized mixed coarse particles pass through the conveyor belt and enter the gas refining workshop. A large amount of N16 catalyst solution is sprayed into the mixed particles. With the assistance of water temperature and ultraviolet light, the organic matter in the mixed coarse particles is quickly converted into methane in large quantities. , propane gas.

The mixed gas passes through the gas pipeline, reaches the power plant area, and enters the gas turbine. Soon the power output of the power plant skyrockets.

A gas turbine generator set with a rated power of 300 megawatts actually exploded into an output power of 351 megawatts when operating at full power.

Compared with ordinary coal-fired generating units, with the same calorific value, the efficiency of coal-fired generating units is only 40%, while the temperature difference + the thermal efficiency of the gas turbine has exploded to 68%.

The improvement in thermal efficiency allows the same fuel to achieve higher utilization, which not only reduces pollution emissions, but also increases power supply. For power generation companies, the cost of power generation will be further reduced.

After running continuously for about two days, the engineers found out the minor problems of the entire system one by one, and then shut down the system for improvement.

Within the factory area.

The electricity generated during these two days of trial operation was not wasted. Instead, it was all used to refine elements and refine methane and propane. The waste is shameful.

The excess methane and propane are stored in a reserve area 2.3 kilometers away from the factory, specifically for emergency backup in case of shortage of raw materials.

In addition, in the gas refinery area, there is also a new process developed by Suiren Company, carbon dioxide decarbonization technology.

Wang Shuo, Du Jinhua and others, wearing gas helmets, looked at the pure carbon powder compressed into carbon bricks. These pure carbon powders are products produced through carbon dioxide decarbonization technology.

"This technology is good, and your Suiren Company's ideas are really unconventional."

Du Jinhua smiled: "After all, energy will not disappear, it will only be transferred. We just preserve it in the form of fixed carbon."

Huaneng's engineers were impressed. They are industry insiders in the power industry and naturally know many of the problems in the domestic power generation industry.

At this stage, the domestic power industry faces problems including long-distance transmission losses, which account for 6 to 10% of total power generation; another problem is the uneven spatial and temporal distribution of electricity.

In particular, waste power such as wind power and photovoltaic power can be called the killer of the power grid, which greatly increases the difficulty of power regulation.

The emergence of carbon dioxide decarbonization technology is to solve the problem of power regulation and convert the electricity in the surplus period into fixed carbon. When the power demand reaches the peak area, the fixed carbon is added with water, refined into water gas, and sent into the In gas power plants.

In this mode, the energy generated by wind power and photovoltaics can be fixed, stored for a long time, and used anytime and anywhere.

Carbon dioxide decarbonization workshop.

Several engineers are trying to fix a few minor issues.

This technology is another big application of six-cone ball oxygen.

The decarbonization workshop extracts carbon dioxide from the atmosphere, turns it into liquefied carbon dioxide through compression and condensation, and then injects six-cone oxygen for decarbonization. The refined products are pure carbon powder and pure oxygen.

The pure oxygen is not wasted, but is directly sent to the gas power generation system to improve the full combustion rate of the gas, and the excess pure oxygen will be released into the atmosphere.

"Mr. Du, with your technology, there is no need to build energy storage reservoirs and the like, and it reduces carbon dioxide in the atmosphere. The carbon neutrality trap of those foreigners is no longer effective for us." Wang Shuo smiled broadly.

Due to the need for environmental protection and carbon neutrality, the thermal power industry, which accounts for the largest proportion of domestic carbon dioxide emissions, is the first industry to bear the brunt.

Especially after the signing of the Copenhagen Accord in December last year, China's environmental pressure has increased day by day.

This also accelerated the in-depth cooperation between the five major power generation groups and Suiren Company.

Huaneng is the first power generation group to take advantage of the situation.

The model of Weizhou coal gangue power plant is not yet its final form, because the power plant does not yet have supporting photovoltaic fields, wind power plants, etc. These waste-to-energy plants are a huge supplement to the gas refinery.

The next step for Huaneng Group is to introduce composite solar panels from Snail Industry. Ning District is a solar energy-rich area, with the total annual solar radiation exceeding 1,740 kilowatt hours/square meter.

With the successful trial operation of Weizhou coal gangue power plant, the joint report of Snail Industry and Huaneng Group has also reached the hands of the other four power generation group CEOs, and now they are even more eager.
