On the last day of October, after several days of adaptation, the employees have adapted to the new office location.

The temperature during the day was still scorching hot, but at night, Li Hao already felt a little cool.

The northern heating season is about to enter, and he is very concerned about the heating of the staff dormitories. The heating of the bamboo building and this area is also solved by the geothermal heating station.

Just when Guo Jianzhuo came to check the usage of the geothermal heating equipment, Li Hao came to the geothermal station with him.

Li Hao and his group came to the geothermal station, which used to be a somewhat remote place, and it was located by a small river. There are almost no people around.

Jiang Long, the manager of the geothermal station, got the news and immediately greeted Li Hao and the others at the door.

After seeing Li Hao get off the car, he quickly ran to Li Hao's side, and said with a flattering smile, "Mr. Li, all the work of our geothermal station has been completed, and it can be operated stably now. Welcome Mr. Li to inspect it."

Li Hao could tell at a glance that he was here to claim credit for himself. The company's talent promotion system has always been fair.

But there are all kinds of people, and some people like to flatter. He knew that this kind of person was extremely good at fighting in the office.

Their characteristic is to love pondering. A small thing can have different meanings.

Li Hao was afraid that he would think too much, so he made the most formulaic smile, and encouraged him: "Manager Jiang, you have done a very good job in completing it within the strict time limit."

After Jiang Long heard Li Hao's praise, he seemed to have taken Shiquan Dabu pills. Feeling a little light all over.

He immediately led the way and led Li Hao to visit the geothermal station. Emphatically introduce the management of geothermal stations,

It is to continuously demonstrate his management ability, intentionally or unintentionally, to claim credit for himself.

They finally came to the core equipment of the geothermal station. This is a big boiler.

Above him is a steam turbine, and below him is a metal rod containing flame metal.

The Yanjin, which has penetrated deep into the ground, uses an extremely efficient method to direct the greatest heat in the ground into the boiler.

Seeing the stable operation of the equipment, Guo Jianzhuo asked Jiang Long, "How is the operation of the equipment, and how has the actual thermal conductivity of Yanjin changed?"

Jiang Long replied immediately: "The equipment is working very well, but we found a problem during use.

The heat transfer efficiency of Yanjin gradually slowed down, and at this time, it was replaced with a Yanjin located elsewhere, and it could provide sufficient heat again. "

"Manager Jiang, you just need to keep replacing the Yanjin rod. The reason for this phenomenon is that the two thermal systems have almost reached thermal equilibrium. When the surrounding hot magma flows to the Yanjin edge in the crust, it will return to normal. .”

While they were discussing, they left the hot place.

Li Hao visited the entire geothermal station, he was a little surprised. He basically didn't participate in the establishment of the geothermal station, so he doesn't know much about the project.

Unexpectedly, the geothermal station is divided into two parts. One part is a geothermal heating station and the other part is a geothermal power station.

When the heating season comes, the geothermal heating system is activated to heat the entire covered area.

In normal times, geothermal energy is mainly responsible for generating electricity.

When Li Hao saw this plan, he was very satisfied. I remember that Shencheng, Liao Province, where he lived since he was a child, has a large part of the heating provided by coal-fired power stations.

That is to say, for the sake of environmental protection, many coal-fired power stations are demolished. A dedicated heating station was established.

These measures have advantages and disadvantages. Correspondingly, the heating cost increases a lot every quarter.

It is because the heating station only works in the winter season. All items that are served according to the season, they have a characteristic. It is not open for a year, but it is open for a year. I want to earn back all the rest of the rest of the time at once.

Now that a geothermal power station is established, the overall equipment can be effectively utilized at all times. Originally, the geothermal station is the construction cost and operating cost.

In this way, the cost shared to each household is very low, so that everyone can enjoy the fruits of technological development.

After the visit, Li Hao said happily: "Manager Jiang, you have done a very good job. Especially the operation of the power station unit is very stable. I think the power output of the steam turbine is very strong."

Jiang Long said confidently: "Of course, it doesn't matter whether it is a thermal power plant, a nuclear power plant, or our geothermal power plant.

As long as heat energy is converted into electric energy, the combination of boiler and steam engine is used as the energy conversion device.

But the efficiency of our current boiler plus steam engine is completely different from the previous boiler plus steam engine. We are a steam engine in a supercritical state.

The efficiency of energy conversion is as high as 67%, which has surpassed the efficiency of steam engines in most countries. "

Li Hao also knows the scientific principle of the supercritical state of the steam engine. This is a high-performance supercritical steam engine developed in recent years.

The supercritical state mainly refers to the operating medium water of the steam engine, and its critical parameters are 22.129MPa and 374.15°C.

At this pressure and temperature, the densities of water and steam are the same, which is called the critical point of water.

By the time this critical state is reached, water and steam have mixed into one substance. When the steam at this pressure begins to hit the steam turbine blades, it will bring great kinetic energy.

When the pressure in the boiler is greater than the critical pressure of water, the boiler in this state is a supercritical boiler.

The steam temperature in the furnace is not lower than 593°C or the steam pressure is not lower than 31 MPa, which is called ultra-supercritical.

Building such a boiler requires extremely high skill. But the results are also very impressive. It can greatly improve the energy conversion ratio of the steam engine. Even beyond the point of internal combustion engines.

Li Hao thought of this in a flash. He didn't expect the company to use supercritical steam engines.

This kind of high-performance steam engine cannot be bought internationally. It must be a product developed by them themselves.

"Manager Jiang, how about the stability of the equipment in our geothermal heating station? Don't there be any accidents that interrupt the heating." Li Hao asked seriously.

Li Hao had just learned about the operation of the geothermal station. Geothermal heating stations are expected to account for a small proportion of profits. They are mainly popular projects developed in cooperation with the government.

If the heating season comes, the equipment will have an accident. This is not a popular project, but a disturbing project.

Just like last year, due to environmental protection requirements, many provinces and cities carried out one-size-fits-all coal-to-gas projects.

You must know that it took Yanjing more than ten years to completely get rid of the reality of using coal for heating.

Some places even wanted to complete it in a short period of time, which directly caused a gas shortage. Especially when most of Huaxia's natural gas resources need to be outsourced.

Except for a few countries such as Russia, due to various concerns, they couldn't bear to abandon this big client. Continue to maintain low supply.

Major natural gas suppliers have taken the opportunity to raise prices, or are waiting to sell, directly cutting off gas supply. In the end, most of the projects were unfinished, and coal-fired heating continued to resume.

Now they use geothermal energy, which is really environmentally friendly energy. It also has stable, efficient and long-lasting characteristics.

Heat is generated inside the earth, and a large part of the heat accumulation is due to the rotation and revolution of the earth, which causes the lavas inside the earth to rub against each other and accumulate energy.

As long as the mass of the earth is not greatly reduced, or the orbit of the earth is shifted. Control the intake of energy, this energy can be said to be almost inexhaustible.

Jiang Long immediately assured: "Mr. Li, don't worry, the equipment construction standards of our geothermal station are all built according to the highest standards. Usually there are engineers to inspect, and there will never be any major accidents."
