Q: What is the difference between white and black peat: The "black peat" is more dense, but it is not suitable for the production of humic acid and humic acid fertilizer.

Q: How many tons of coal can be produced by 1 tons of coal? What is the proportion of them in general?: The amount of ash in the coal depends on the ash content of the coal. General coal ash from 10% to about 40% or even higher

Q: What is the standard of coal: Characteristics of mineral raw materials(1) physical properties of coalThe physical property of coal is the external manifestation of certain chemical composition and molecular structure of coal. It is determined by the factors such as the original material and its accumulation conditions, the conversion process, the degree of coalification and the degree of wind and oxidation. Including color, gloss, pink, specific gravity and bulk density, hardness, brittleness, fracture and conductivity, etc.. Among them, in addition to the specific gravity and conductivity need to be measured in the laboratory, the other can be determined according to the naked eye observation. The physical properties of coal can be used as the basis for the preliminary evaluation of coal quality, and it is used to study the cause of formation and metamorphism of coal.

Q: Why is coal spontaneous combustion?: The spontaneous combustion of coal, especially those of low-grade bituminous coal, occurs when the heat absorbed from the environment is greater than the amount of heat released into the environment

Q: Is it useful to use bamboo charcoal bags? Bamboo charcoal package is activated carbon? Want to buy one, do not know how to choose?: Bamboo charcoal package is only ordinary bamboo charcoal, its adsorption is very small, very easy to saturate, saturated and released

Q: Does Medicinal Charcoal Tablets have any effect on gout: So gout patients should eat alkaline foods, such as vegetables, potatoes, sweet potatoes, milk, melon and watermelon is not only alkaline food, there is a good diuretic effect, is conducive to the excretion of uric acid.And Medicinal Charcoal Tablets is alkaline food can eat.

Q: Air purification carbon bag useful?: When exposed to toxic and harmful gases and air pores in the surface of the activated carbon, adsorption of poisonous and harmful gases will be generated by these pores adsorbed into the pores in the field, but when the poisonous and harmful gases in the air and the surface of the activated carbon has no chance to contact when activated carbon itself is toxic and harmful gases will not take the initiative to contact with the adsorption the surface of the. That is to say, the use of indoor air in the corner or on the ground spread some of the activated carbon purification method

Q: Coal formation process and time: Coal is millions of years of plant leaves and roots, stacked on the ground with a layer of very thick black humus, due to changes in the earth's crust constantly buried underground, long isolated from the air and under high temperature and pressure, after a series of complex physical and chemical changes and other factors, the formation of black combustible sedimentary rocks, which is the coal forming process.

Q: Please introduce in detail, thank you, and there is no machine production of charcoal: There are two kinds of preparation methods:(1) the kiln, with mud kiln, filled with wood burning from the kiln door or door, the carbonization of wood in the kiln, volatiles escape and residual charcoal;

Q: Coal is used to do?: . Some low ash, low sulfur and high HGI anthracite is also used as raw material for blast furnace injection. Coal: coal soot level top coal, it is characterized by a higher ignition temperature (350 - 360 DEG C), high calorific value, weak bond or not. Coal is mainly used for power generation and power plant boiler fuel. The use of coal, and the other with the use of high volatile coal is also a good way. Lean coal: low volatile, low bond strength, can be used alone to coking. As with other suitable for coking coal blending, lean coal incorporation will make block increase the degree of coke products.
