Chapter 394: Geothermal heating

On the last day of October, after a few days of adjustment, the employees had adapted to the new office.
The temperature was still hot during the day, but at night Li Hao felt a little cool.
He is about to enter the northern heating season and he pays great attention to the heating of staff quarters. The heating of Zhuzi Building and this area is also solved by geothermal heating stations.
Just when Guo Jianzhen came to check the use of geothermal heating equipment, Li Hao came to the geothermal station with him.
Li Hao and his team came to the geothermal station, which used to be a somewhat remote place on the edge of a small river. There were few people around.
Jiang Long, the manager of the geothermal station, got the news and immediately greeted Li Hao at the door.
After seeing Li Hao getting out of the car, he hurriedly walked to Li Hao and smirked and said, "General Manager Li, all the work of our geothermal station has been completed and can now run stably. General Manager Li is welcome to inspect.
At a glance, Li Hao saw that he had come to invite himself for credit, and the company's talent promotion system had always been fair.
But there are all kinds of people, and some people like to make fun of them. He knew that such people were extremely good at office struggles.
They are characterized by love for thought. A small thing can be thought of differently.
Li Hao was afraid that he would think more and make a most formulaic smile, encouraging: "Mr. Jiang, you can complete it on time in a strict time. You are doing very well."
After Jiang Long heard Li Hao's compliment, he seemed to have taken Shiquan Dabu Wan. I feel a little fluttering all over my body.
He immediately led the way and led Li Hao to visit the geothermal station. Focusing on the management of geothermal stations,
It is to constantly show his management ability, intentionally or unintentionally inviting credit for himself.
They ended up next to the core equipment of the geothermal station. This is a big boiler.
He was followed by a steam turbine, and below it was a metal rod containing flaming gold.
Deep into the ground, Yan Jin, it uses an extremely efficient way to direct the largest amount of heat in the ground to the boiler.
After seeing the equipment running steadily, Guo Jianyu asked Jiang Long with relief, "How is the equipment running and how does the actual thermal conductivity of Yanjin change?"
Jiang Long replied immediately: "The equipment is working very well, but we found a problem in use.
Yan Jin's efficiency of transferring heat gradually slowed down. At this time, Yan Jin, who was located elsewhere, could provide sufficient heat. "
"Mr. Jiang, you only need to replace it continuously, and the Yanjin stick can be used. The reason for this phenomenon is that the two thermal systems have reached thermal equilibrium. When the surrounding hot magma flows to the Yanjin edge in the earth's crust, it will return to normal. . "
While they were discussing, they left the place where the temperature was a bit hot.
Li Hao was surprised when he visited the entire geothermal station. He did not participate in the establishment of the geothermal station, so he did not know much about the project.
Unexpectedly, the geothermal station was divided into two parts. One part is a geothermal heating station, and the other is a geothermal power station.
When the heating season comes, the geothermal heating system is started to heat the entire coverage area.
In normal times, geothermal energy is mainly responsible for power generation.
Seeing this plan, Li Hao was very satisfied. Remembering where he lived in Shencheng, Liaoning, a large part of the heating was provided by coal-fired power stations.
That is, for environmental protection, many coal-fired power stations are being demolished. A dedicated heating station was established.
These measures have both advantages and disadvantages. Correspondingly, heating costs have been raised significantly each quarter.
It is because the heating station only works in the winter quarter. All items that are serviced seasonally have one characteristic. It doesn't open for one year, it opens for one year. You should earn all the money for rest at one time.
Now that a geothermal power station is built, the entire equipment can be effectively used at all times. The original geothermal station is the construction cost and operation cost.
In this way, the cost spread to each household is very low, so that everyone can enjoy the results brought by the development of science and technology.
After the visit, Li Hao said happily, "Mr. Jiang, you are doing very well. In particular, the generating unit operation is very stable. I think the steam turbine power output is strong."
Jiang Long said confidently: "Of course, now whether it is thermal power or nuclear power plants, or our geothermal power stations.
As long as it involves the conversion of thermal energy into electrical energy, a combination of a boiler and a steam engine is used as an energy conversion device.
However, the efficiency of our boiler and steam engine is completely different from the previous boiler and steam engine. We are using a supercritical steam engine.
The efficiency of energy conversion is as high as 67%, which exceeds the efficiency of steam engines in most countries. "
The supercritical state of the steam engine, Li Hao also knows this scientific principle. 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 374.15c.
At this pressure and temperature, the density of water and steam is the same, which is called the critical point of water.
When this critical state is reached, water and steam have been mixed into the same substance. When this pressure of steam begins to impact 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 593c or the steam pressure is not lower than 31mpa.
Building such a boiler requires extremely high technology. But the results are also very impressive. It can greatly improve the energy conversion ratio of the steam engine. Even beyond the point of the internal combustion engine.
Li Hao thought of this in an instant. He did not expect that the company could use a supercritical steam engine.
This kind of high-performance steam engine cannot be bought internationally. It must be a product they developed independently.
"Mr. Jiang, how is the stability of our geothermal heating station equipment? Don't have an accident that interrupts heating at that time." Li Hao asked seriously.
Li Hao has just learned about the operation of the geothermal station. Geothermal heating stations are expected to account for a small percentage of profits. They are mainly cooperating with the government to develop popular projects.
If the heating season comes, the equipment has an accident. This is not a popular project, but a disturbing project.
Just like last year, because of environmental protection requirements, many provinces and cities carried out a one-size-fits-all coal-to-gas project.
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 want to complete it in a short time ~ EbookFREE.me ~ The result is a direct shortage of gas. In particular, most of China's natural gas resources need to be purchased.
Except for a few countries such as Russia, due to various concerns, they could not bear to leave this big customer. Continue to maintain low supply.
The major natural gas suppliers have taken the opportunity to raise prices, or sold them after the price, and directly interrupted gas supply. In the end, most of the projects were ruined, and coal-fired heating was resumed.
Now they use geothermal energy, which is truly environmentally friendly. It also has stable, efficient and long-lasting characteristics.
Heat is generated inside the earth. A large part of the heat accumulation is due to the rotation and revolution of the earth, which causes the lava 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 your energy intake. This energy is almost inexhaustible.
Jiang Long immediately assured: "General Manager Li is assured that the equipment construction standards of our geothermal stations are all constructed in accordance with the highest standards. Usually, engineers will inspect them and there will be no major accidents."
