- Q: There are no certain indicators? What is the market price?
- It should belong to the low quality of coal, but not the lowest, the price should be based on its quality. Washing is generally about half of clean coal.
- Q: I would like to ask what is the pit coal?
- Direct delivery of coal from coal mine pit. That is to say, we do not have to go through the delivery of coal that is rightIt is generally said that the fresh directly out of the mouth
- Q: Activated carbon can be reused?
- The price is less than half of the original carbon! You say the effect can be good? If you use activated carbon, I can! I do the activated carbon business here in Henan! So I know the Henan side of the activated carbon is the lowest in the country!
- Q: On behalf of the company to study the coal test, which can help me to explain the online test of coal each indicator of the process, thank you
- 1, the moisture of coalThe water content of coal is an auxiliary index in coal pricing.The moisture of coal directly affects the use, transportation and storage of coal. With the increase of the water content of coal, the useful component in coal is relatively reduced, and the water is changed into steam when it is burnt to absorb heat, thus reducing the calorific value of coal. The increase in the moisture content of the coal, but also increased the invalid transport, and bring difficulties to the unloading. The characteristics of winter cold area, often frozen car, truck production influence, influence effect, wagon turnover, exacerbated by transport stress.The coal moisture is also easy to cause the coal to stick the storehouse and reduces the coal bunker capacity, even has the storehouse accident.With the increase of mining depth, the development of mining mechanization and the strengthening of underground safety production, as well as the implementation of measures such as spraying water, coal seam water injection and comprehensive dust prevention, the water content of raw coal is increasing. To this end, in addition to all aspects of coal mining, coal mining in design and in the process of mining excavation, ventilation and transportation for reducing coal moisture measures, measures should also be taken in the ground processing of coal to reduce the moisture content of coal.
- Q: What is the calorific value of standard coal?
- China's per kilogram of standard coal calorific value of 7 million cards
- Q: Artificial gamma (density) curve: the coal seam has obvious abnormal reflection;Apparent resistivity curve: the coal seam is relatively low amplitude anomaly, and the sandy mudstone is high amplitude reflection;Natural gamma curve: the coal seam is relatively low amplitude, but the sandy mudstone is high amplitude.Graduation picture does not explain the above explanation is a bit simple, trouble to explain a little bit more,Sit back and wait
- As well as the "four low" characteristics: low natural gamma, low compensation density, low cross section, low acoustic impedance, and dark color;
- Q: The coal industry often crushed to the full combustion, its purpose is to reduce the waste of coal (A.) B. to reduce oxygen consumption, reduce carbon dioxide C.The coal industry often crushed to the full combustion, its purpose is to ()A. reduce coal wasteB. reduce oxygen consumptionC. reduces carbon dioxide emissionsD. reduces the formation of acid rain
- C, the industry often put coal after crushing, increasing the contact area of coal and oxygen, can make full combustion of coal, rather than to reduce carbon dioxide emissions, so the wrong option.D, the industry often put coal after crushing, increasing the contact area of coal and oxygen, can make full combustion of coal, rather than reduce the formation of acid rain, so the wrong option.So choose: A.
- Q: How to calculate the investment of coal
- It refers to the investment in the construction of coal mine after the formation of the production capacity of the coal, which is one of the economic indicators of the coal mine construction evaluation of investment results
- Q: Bamboo charcoal bag placed in the room
- If you want to live in as soon as possible, there are several methods to help: 1 to half a catty Black Tea soaked with boiling water, the water drained, Black Tea will put a pot (that is, table container area comparison), placed in the room, or directly on the furniture inside, the surface of tea has strong adsorption capacity, can absorb indoor harmful gas as the size of the room, can get many pots. Place more than 24 hours, there will be significant improvement. More than and 2 some green plants, such as Chlorophytum, Sansevieria, ivy, also have the effect
- Q: How to distinguish the mechanism of charcoal is good or bad?
- 2 volatile matter content, depending on the carbonization temperature. According to different uses, we can burn low, medium temperature carbon, also can burn high temperature carbon. In the high temperature calcination release of CO, CO2, H2, CH4 and other volatile gaseous carbohydrate, its content is generally 12 to 20%. High temperature carbon released by the above volatile less, its content is generally less than 5%.
