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: First of all, I would like to ask is: what is the need for steelmaking coal or anthracite coal? How much coal can be made of steel? Understand the answer or add friends do not understand this!! ~: Do you dare to use coal? Play where. There are farmers used, 10% ingot of molten steel and bean curd residue, because more sulfur.

Q: The basic situation of coal occurrence in coal mining area: (1) the origin of the edge coal. The main reasons for the formation of edge coal are as followsThe arrangement mode of the utility model is that the straight groove and the cutting hole are directly connected to form a cutting edge triangle coal,Is the formation of the edge of the coal artificial factors; two is affected by the fault and geological structure, can not ruleIt is a natural factor for the formation of the edge coal to arrange the complex block of the working face. ThreeThe coal pillar and the coal pillar in the mining area have a certain mining value:

Q: Tea and activated carbon which adsorption effect is goodSuch as the title: On the surface of the particles, a layer of equilibrium surface concentration is formed, and then the organic matter impurities are absorbed into the activated carbon particles

Q: Bamboo charcoal package is valid: Personally think that should still haveThe adsorption capacity was related to the particle size, and the adsorption rate of fine carbon was higher than that of the 80 mesh, while the bulk carbon was the slowest.Deodorant bamboo charcoal bag placed in the refrigerator, wardrobe, shoe cabinet, toilet, car and other places, every 2~3 months in the sun exposure once, you can get rid of bamboo charcoal adsorption of moisture and odor, to maintain a good function of bamboo charcoal. Charcoal bag placed more than one or two years, the demolition of the bamboo charcoal particles buried in the soil, used to improve soil activity, prevent the occurrence of pests and diseases, promoting plant growth.

Q: What industry is washed coal: According to the coalification degree of coal, all the coal in our country is divided into three kinds of coal, lignite, bituminous coal and anthracite coal. According to the characteristics of coal gasification and industrial use, the lignite is divided into 2 categories, anthracite is divided into 3 categories. Bituminous coal is more complex, divided into 4 grades according to volatile, that is, Vdaf > ~ ~ ~ 20%, > ~ ~ ~ 20 ~, ~ ~ 28 ~ + 37% and > >, divided into low, medium, medium and high volatile bituminous coal of the four kinds of (37%) ~ ()

Q: What is the use of power coal: Use of power coalFrom a global perspective, the output of power coal accounts for more than 80% of total coal production. The world's 10 largest coal company mainly produces coal, the proportion of the company's total output accounted for about 10 coal 82%; U.S. coal production accounts for more than 90% of its total production; China coal production has accounted for about 80% of the total output of coal.In foreign countries, most of the power coal used to generate electricity, industrial boilers also have some dosage. About 55% of the world's coal is used to generate electricity, and the incremental demand for coal is basically in the electricity sector. The consumption structure of power coal in the Chinese, there are more than 65% for thermal power generation; second is the building materials of coal, coal consumption accounted for about 20% of the cement yongmeiliang maximum power consumption; the rest of the coal distribution in metallurgy, chemical industry and civilian.

Q: The development history of activated carbon: Prior to the invention of activated carbon as a patent in the early twentieth Century, there was a history of documented and many references to the history of charcoal applications.In 3750 BC, it was known to the Egyptians and Sumerians that the earliest use of charcoal.In the 1550 BC, ancient Egypt had charcoal as a medical record.The Greek doctor F Pokela di (Hippocrate) and Pliny (460-359 BC) with charcoal treatment of epilepsy and anthrax.In 450 BC, the Phoenician merchant ship recent research shows that drinking water is stored in wooden barrels burning in. It is the storage method of marine drinking water in history until eighteenth Century.During the same period, Hindu religious documents also mentioned the use of sand and charcoal to filter and purify drinking water.

Q: How to get charcoal: To do the torch, the torch took his hand, right click on the tree, the tree burning, the tree after the burn, take the axe to cut off the withered tree, falling charcoal

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%.
