Calcined Anthracite Coal


• Calcined Anthracite Coal Feature:

All of our goods are made in the best quality with high carbon, low ash, low Sulphur, low moisture.



• Calcined Anthracite Coal Application:

Calcined anthracite coal/gas calcined anthracite coal/carbon raiser is mainly used in steelmaking in electrical stove, screening water, shipbuilding sandblast to remove rust. It can reduce the cost of steelmaking effectively by replacing the traditional petroleum coke of carburant. Also, it can improve the carbon content in steel melting and ductile iron foundry.

Q:What is the use of power coal
With the coal category, mainly lignite, long flame coal, non caking coal, lean coal and a small amount of anthracite. From the commodity coal, the main washing mixed coal, washed coal, coal, coal, etc.. The poor quality coal mainly refers to the low ash value (less than 40%) which is unfavorable to the operation of the boiler (less than 15). Bituminous coal of 73 MJ / kg, anthracite with low volatile content (less than 10%), lignite with high moisture content and high sulfur content (more than 2%), etc..
Q:The nature and classification of coal gangue?The classification and properties of coal gangue for writing papers
1, according to the sources classification according to the coal gangue output that can be divided into the source of coal gangue gangue, gangue, coal roadway rock gangue, gangue gangue and stripping hand selected, some of the coal gangue as a source according to the classification of(1) the gangue discharged from the raw coal washing process is called the washing waste. The concentration of the washing waste is concentrated, the grain size is fine, the calorific value is higher, the clay mineral content is high, the content of carbon, sulfur and iron is generally higher than other kinds of gangue(2) coal gangue in the coal mine roadway tunneling process, all along the seam mining, excavation engineering from coal gangue, coal gangue, coal roadway called Xiang Gan is mainly composed of mining coal seam roof and floor rock, interlayer composition, carbon content and calorific value often containing certain, sometimes containing CO with mineral resources.(3) the waste rock roadway in coal mine construction and rock tunnel excavation process, all along the seam tunnelling emissions produced by coal gangue, gangue rock roadway rock roadway. Collectively, gangue containing rock complex types, discharge is more concentrated, its low carbon or carbon, so no calorific value.
Q:Definition and classification of carbon
And white carbon black carbon is usually divided into charcoal and white carbon black carbon, which can be divided into white carbon carbon and carbon black and white phillyraeoides carbon. White carbon, refers to the wood in a kiln at the end of hot carbonization Bachu from the kiln, then put out with wet sand mud, in the burning process, charcoal and air calcination, the external carbon is oxidized to produce white ash attached on charcoal. This carbon to hard, heavy, black, color section with metallic luster, when the sound of metal tapping will have a clear and melodious, burning without smoke, high heat, lasting combustion, little black powder drop, and is very suitable for the use of water purification and bath. Black carbon, obtained by the method of rotary kiln flameout, is contrary to white carbon. The old people in the past carbon brazier burned most of the carbon is burnt black carbonaceous rough. The utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model has the. It is easy to scattered black powder, not suitable for dishes, drinking water and bath, can be used for dehumidification and deodorization.
Q:What is food grade activated carbon
Food with activated carbon has a large surface area, strong adsorption capacity, high wear resistance strength, filtration speed and other characteristics, and is suitable for liquid phase adsorption and gas adsorption, and adsorption, decolorization, purification, filtration, carrier, deodorization, drying, preservation, recovery, purification, smell and other functions.
Q:What is the proportion of raw coal
Coal (water < 5%) is 0.8~1.0 tons / cubic meters, coal (water = 5%) is 0.9~1.1 tons / m3, anthracite (dry and bulk) is 0.8~1.2 tons / m3, anthracite (dry, small) is 0.7~1.0 tons / m3, bituminous coal (dry and bulk) is 0.8~1.1 tons / m3, bituminous coal (dry, small) is 0.8~0.9 tons / m3, lignite (dry and bulk) is 0.8~0.9 tons / m3, lignite (dry, small) is 0.6~0.8 tons / m3.
Q:What industry is washed coal
According to the bond can be divided into 5 or 6 grades, namely GR.I. ranged from 0 to 5, said the bond or weakly caking coal; GR.I. > 5 ~ 20, said weakly caking coal; GR.I. > 20 ~ 50, known as the medium weak caking coal; GR.I. > 50 ~ 65, said medium strong caking coal; GR.I. > 65, said the strong caking coal. In the strong caking coal, 25mm or B if Y > > 150% (> 28% for Vdaf, the coal, coal, b > 220%) is called strong caking coal. See also GB5751-1986. The basic characteristics of various types of coal are as follows:
Q:What is the proportion of dry activated carbon
One is the chemical binding elements, mainly hydrogen and oxygen, these elements are due to incomplete carbonization and the residue in the carbon, or in the process of activation, non carbon and activated carbon surface chemical foreign combination, such as water vapor activation, surface activated carbon is oxidized or water vapor oxidation
Q:Activated carbon rain has been poured into the useful
Look at the size of the smaller carbon particles and air contact area is larger, the specific surface area is larger, the adsorption performance is better, but the smaller the particle crushing loss, the production process is more and more dust, the higher the costs, so many manufacturers to reduce costs, the use of large granular activated carbon of course, the performance is not good, active carbon in about 0.5 mm average particle size so as to achieve the best performance, and make sure it's not powder, no pollution. Recommended to choose the particle diameter between 0.42-0.85 mm of activated carbon products.
Q:Effect of bamboo charcoal in bulk
The specific surface area is the size of the surface area per unit mass. That is the sum of the surface area of 1 grams of carbon and the total pore area. Bamboo charcoal in the firing temperature above 500 DEG C, the specific surface area between 150 square meters to 350 square meters /g /g; activated carbon iodine value can reach 1000-1200 mg / g, the specific surface area can reach 3000m2/g (50g/ packet adsorption area equivalent to 50 football fields), and bamboo charcoal products iodine adsorption value of 500-700 mg / g carving crafts, the iodine adsorption value was only 650 mg / g. Therefore, activated carbon has an absolute advantage in the adsorption performance. The adsorption capacity is 2-3 times of charcoal and charcoal; can accommodate the number of harmful gases and carbon charcoal carving is 10-20 times.
Q:How to burn charcoal barbecue?
Charcoal kindlingIn accordance with the commonly used types of charcoal into fruit charcoal, machine-made charcoal, oak charcoal
