"Mr. Zhang. Zhang Xiaobei was idle in the office, and Bai Xiaobai pushed the door in.

"Sit. Zhang Xiaobei got up.

"Now the matter of your coal washing plant is also handed over to our consulting company to promote. Bai Xiaobai sat down.

"Okay, with you in the field, it is estimated that all kinds of work will be carried out quickly. Zhang Xiaobei was also happy to do this.

"I don't know much about the type of coal and the use of coal. Of course, there are also online, but they are not systematic and comprehensive. ”

"So, with the help of the coal washing plant, I also want to figure this thing out. ”

Bai Xiaobai said with a smile.

"There's no need. "Yes, the coal washing plant, it is mainly a technical problem, and it has a weak relationship with the type of coal and the use.

"It's like I'm learning from you. Bai Xiaobai said.

"Why should I tell you. Although Zhang Xiaobei said this, he had already made a draft in his heart.

"You're idle, what about this reason?" Bai Xiaobai smiled evilly.

"Well, that's a good reason. Zhang Xiaobei said that it was not only Jinsheng who wanted to come to them for consultation, "I am only responsible for speaking, not writing." ”

"It's okay, Lao Zi has a voice recorder. Bai Xiaobai said, and took out the voice recorder and put it on the table.

Zhang Xiaobei shook his head with a smile and began to popularize science.

Originally, as far as the coal varieties in our country are concerned, they can be divided into three categories: lignite, bituminous coal and anthracite according to the degree of coalification and volatile matter.

The difference between anthracite and bituminous coal is based on volatile matter, and more than 10% belongs to bituminous coal, otherwise it is anthracite.

The criterion for distinguishing lignite from bituminous coal is calorific value, which is related to the degree of coalification.

The calorific value is less than 5800 kcal is lignite, and vice versa is bituminous coal.

Among these three major classifications, lignite is divided into two small varieties, namely lignite No. 1 and lignite No. 2. The phosphorus content is mainly different, the phosphorus index of No. 1 is less than 30, and the phosphorus index of No. 2 is between 30 and 50.

There are 12 sub-varieties of bituminous coal, namely lean coal, lean coal, lean coal, coking coal, 1/3 coking coal, fertile coal, gas fertile coal, gas coal, 1/2 medium sticky coal, weak sticky coal, non-sticky coal and long-flame coal.

Anthracite coal according to different volatile content, there are also three sub-varieties, the volatile content is less than 3.5, belongs to the No. 1 anthracite, between 3.5 and 6.5, belongs to the No. 2 anthracite, between 6.5 and 10, belongs to the No. 3 anthracite.

Natural anthracite is mainly a chemical raw material in the first place, especially anthracite lump coal. However, in the past two years, everyone has been using aerospace furnace technology, the scope of use of lump coal is gradually shrinking, and the civilian market is slowly forming.

In addition, the use of anthracite coal is becoming prominent.

Secondly, after washing and processing, according to the softness of the coal quality, it can also be used as sintering coal and injection coal in the steel industry, of course, there are also some power plants to reduce sulfur through coal blending, and secondly, it is civil.

Jinsheng Group is mainly anthracite, and its basic uses are the above.

The coal washing plant can be washed and processed according to the coal standards of the above-mentioned industries.

The twelve sub-varieties of bituminous coal are basically used for power coal, that is, for power generation, coal for coking, that is, coke, and coal for gasification, that is, for gas production.

The uses of lignite are also chemical, gasification, steelmaking, and civil use.

As for the specific use, usage and indicators of each small coal type, you can ask Baidu according to the name of the small coal type provided.

"It's over?" Zhang Xiaobei asked rhetorically after a brief introduction.

"It's over, or how complicated do you think? Zhang Xiaobei chuckled.

"Then what are your medium-term considerations for Jinsheng's existing coal use?" Bai Xiaobai continued.

"That's it, Mr. Bai. At the beginning of the company's integration, the six mines were all producing standard No. 3 anthracite. The coal seam belongs to the No. 3 coal seam, and due to its high hardness, the variety belongs to hard anthracite. ”

"Our coal seams are generally divided into four coal seams: No. 2, No. 3, No. 9 and No. 15. ”

"The two newly acquired coal mines belong to No. 2 anthracite, which is soft anthracite due to its high grindability index. ”

"The original layout of the three special line mines in the six mines in the future is one chemical coal mine and two steel-making coal mines, and the division of the three road transportation mines will also be two chemical coal mines and one steel-making and sintering coal mine. ”

"The two newly acquired coal mines are mainly steelmaking and injection coal. ”

"Of course, after washing and processing, there is no problem for our coal to be used for civilian use. ”

"Thermal coal blending is sold as a piecemeal, because the price of anthracite is high and the use of power plants is not cost-effective, so it is impossible to form bulk sales. ”

"Of course, whether it is a chemical standard or a steelmaking standard, power plant suppliers can use it, anyway, coal blending, it is a cost-effective problem. ”

"My personal meaning is very clear, that is, in the future, coal for sintering, injection and chemical will become the main use of Jinsheng's existing coal mines in the future. ”

"In terms of the intrinsic quality of coal, it has been fully utilized. ”

This is all something formed in the head, of course Zhang Xiaobei said it more fluently.

"Well, in that case, I can go back and prepare the plan. After Mr. Bai Xiaobai finished speaking, he got up and prepared to go back to the office.

As soon as he walked to the door, Teacher Bai Xiaobai turned around: "Mr. Zhang, I'll give you something, I don't know if you like it or not." ”

"Let's hear it!" Zhang Xiaobei also stood up.

Bai Xiaobai wants to send something, it is definitely not cigarettes and wine or anything like that.

If someone is engaged in consultation, they should send you a decent set of materials that are extremely useful.

"About the composition of the national coal transportation network and coal distribution network information, the sales network of 21 large mining bureaus, the throughput and transportation pattern of 64 inland ports, hundreds of coal concentrated arrival railway stations, more than 200 coal-using downstream enterprises giants, including the latest coal logistics information, and so on. Bai Xiaobai turned around and said very awesomely.

"What's this thing called?" Zhang Xiaobei was very interested.

"Coal transportation knowledge database, a total of 340,000 words. Bai Xiaobai said, with a smile on his face.

"Damn, Mr. Bai, you just played me tricked!" Zhang Xiaobei came back, Bai Xiaobai was obviously asking knowingly just now.

What other varieties and uses of coal!

People even have a knowledge base of transportation, so don't they know exactly what coal varieties and uses are?

"You don't take other people's things for nothing, so ah, even if we exchange information this time, it can be regarded as information sharing!" Bai Xiaobai finished speaking, and went out.

After Zhang Xiaobei heard this, he couldn't help but smile bitterly in his heart.

Teacher Bai, disgusting people don't bring such disgusting things, I won't take other people's things for nothing, I, Zhang Xiaobei, like to "take advantage" the most, okay.

You're kidnapping and swearing, aren't you?
