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:Carbon powder color Potassium Permanganate and the same color of manganese dioxide
Physicochemical propertiesPotassium Permanganate (KMnO4) English Potassium permanganate red purple orthorhombic, granular or acicular crystal. Metallic luster. Relative density 2.703. Soluble in aqueous solution of deep purple red, slightly soluble in methanol, acetone and sulfuric acid. Decomposition of ethanol and hydrogen peroxide. Heating up to 240 degrees Celsius or above. Strong oxidizing agent, reduced to Mn2+ in acidic medium, reduced to manganese dioxide in alkaline or neutral medium, and manganese dioxide produced by Mn2+. Contact with concentrated sulfuric acid is prone to explosion, in the case of cooling, with high concentration of sulfuric acid precipitation of high manganese anhydride black green oily liquid. Contact with organic matter, friction, collision, due to the heat emitted oxygen will cause combustion.
Q:Coal quality test, Mt, Mad, Aad, Vad each represents what mean
The first indicator: moistureThe moisture in coal is divided into internal water, external water, crystal water and waterToo much water in the coal, is not conducive to processing, transportation and so on, combustion will affect the thermal stability and thermal conduction, coking will reduce the coke yield and extend the coking cycleNow we often report the moisture index:
Q:What is the structure of activated carbon?
Activated carbon porous, so the surface area is very large, a cubic centimeter of adsorption area of about one thousand square meters.
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:The necessity of power coal washing
In the coal ash, sulfur, phosphorus and other impurities are harmful, so try to get rid of the impurities, it has very important significance to improve the coal use value. Effective method is to get rid of impurities. Coal coking coal washing and processing must pass through this point, people have a more comprehensive understanding. However, with the necessity of coal washing power, is not yet widely known in large numbers.x0d
Q:The main application value of coal and its impact on China's economy and the world
The use of coal is very extensive, according to the purpose of its use for two main purposes: (1) power coal, (2) coking coal.The main use of power coal in china:Steam coal1) coal for power generation: more than 1/3 of coal in China is used to generate electricity, and the average power consumption is 370g/ (kW / h). The power plant uses the calorific value of coal to convert heat energy into electrical energy. 2) steam locomotive coal: accounts for about 2% of the power coal, the average coal consumption of the boiler is 100kg/ (10000 tons / km). 3) coal for building materials: accounts for more than 10% of the power coal, with the largest amount of cement, followed by glass, brick, tile, etc.. 4 general industrial boiler coal: in addition to the thermal power plant and large heating boiler, the general enterprise and the heating of the industrial boiler model, large quantity and scattered, coal accounts for about 30% of the coal. 5) living with coal: the number of living coal is also large, accounting for about 20% of fuel coal. 6 metallurgical power coal: Metallurgical power coal is mainly used for sintering and blast furnace coal injection, the amount of less than 1% of the coal used for power.
Q:Why is coal spontaneous combustion?
Coal heap in contact with air oxidation occurs, and emit heat. Coal oxidation reaction occurs after the coal pile temperature increases. The coal temperature increases, and the speed of coal oxidation was accelerated. In this way, the temperature makes the coal pile increasing. When the temperature exceeds the coal self ignition when will the spontaneous combustion
Q:How to burn charcoal barbecue?
Oak charcoal ignition methodThe high burning value of charcoal, burning time is long, the density of carbon is relatively large, it is not easy to ignite. Refer to the above 2 kinds of methods that can, tussah charcoal burning time is 2 times of fruit charcoal, charcoal and fruit value is between the combustion mechanism charcoal, charcoal smoke should be smaller than.
Q:The difference between activated carbon and charcoal?
Product overview1, the family decoration, inevitably there will be pollution, formaldehyde, toluene, xylene and ammonia is the main culprit, the indoor air pollution in the car, they will bring a serious threat to human health, the removal of various decoration materials released by the Home Furnishing harmful gases to human health, is the main problem facing customers.
Q:Coal water slurry is used for what?
Coal slurry: is a new, efficient and clean coal based fuel, is a new member of the family of fuel, it is a mixture of 65%-70% of different size distribution of coal, 29-34% or 1% of the chemical additives made of water. Through the multi-channel rigorous process, sieve to the combustion of coal and other ingredients can not be burned, only to retain the essence of carbon to become the essence of coal water slurry. It has the same oil mobility, calorific value is equivalent to half of the oil, known as liquid coal products
