Professional Manufacturer,exporter of Calcined Anthracite Coal;
High quality with best price.

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 are the main equipment of coal chemical industry?
Coal chemical engineering, mainly use the following equipment:Chemical equipment (reactor, gasifier, containers, towers, heat exchangers), coking equipment, crushing and grinding equipment, air separation equipment, and vacuum blower (including centrifugal compressor), compressor and refrigeration equipment, industrial pumps, valves and environmental protection equipment, instrumentation, electrical equipment etc..
Q:Is not all activated carbon can be placed in the refrigerator
And broke into two halves. Can achieve the same effect (steamed bread do not eat!) Or use the burnt briquettes, with a plastic bag wrapped in the refrigerator for a long time can also absorb odor. I wish you good health.
Q:What is coal dry base settlement
According to the different needs of the coal quality test data will have different benchmark conversionThe general has received radical air drying dry skeleton based dry ash free dry mineral base.
Q:Coal can be used to do
5) living coal: the number of living coal is also large, accounting for about 20%. of fuel coal6 metallurgical power coal: Metallurgical power coal is mainly used for sintering and blast furnace coal injection, the use of less than the amount of coal power 1%.
Q:What is the mineral composition of coal?
Hydrogen in coalHydrogen is the second important component of coal. In addition to organic hydrogen, there is also a small amount of inorganic hydrogen in coal minerals. It is mainly present in the crystallization of mineral water, such as kaolin (Al203 / 2Si02, 2H2O), gypsum (CaS04 / 2H20) and other crystalline water. In the whole process of coal metamorphism, with the deepening of coalification degree, the content of hydrogen decreases gradually, and the coal with low coalification degree has high hydrogen content. The general rule is that the hydrogen content decreases with the increase of carbon content. Especially in the anthracite phase is particularly evident. When the carbon content increases from 92% to 98%, the hydrogen content decreases from 2.1% to less than 1%. When the carbon content is between 80 and 86%, the hydrogen content is the highest. In the coal gas and coal, hydrogen content can be as high as 6.5%. When the carbon content is 65 ~ 80%, the content of hydrogen is less than 6%. However, the trend is that the hydrogen content decreases with the increase of carbon content.
Q:There are several categories of coal sampling machine
1: lignite is massive, dark brown, shiny dark, loose texture, containing 40% volatile; burning low, easy to catch fire, burning fast ignition, flame and smoke; carbon content and low heat (due to different coal, calorific value difference), combustion short, frequent coal.2: General bituminous coal is granular, small block, or powder, is black and shiny, delicate texture, containing more than 30% volatile, ignition temperature is not too high, is easy to ignite; carbon content and calorific value of burning high, fast ignition, long flame, there are a lot of black smoke, the burning time is long; most viscous bituminous coal combustion, easy to slag.
Q:Coal chemical production technology is to learn what ah
Employment prospects: coal chemical industry is a national key investment industry, talent demand, development prospects of graduates, 3-5 years of work can become the team or section responsible for workshop supervisor or technician, workshop director or person in charge of the Department.
Q:What is the proportion of dry activated carbon
The other kind of admixture is ash, which is the inorganic part of activated carbon, and ash can easily cause two pollution in activated carbon.
Q:What raw materials to produce charcoal
Charcoal raw materials: mainly to soft broad-leaved fuelwood based. Because of the different species can be divided into: expensive tea, charcoal and bamboo charcoal sticks and other cheap civil charcoal. The tea is mainly produced in carbon carbon, branches of rich forest resources in Northeast China, with oak wood as raw material, firing process and selection of very exquisite. Other cheap civil charcoal is mainly produced in Anhui, Zhejiang, Henan and other places, to elm, willow, wood as raw material. Easy to buy cheap and popular, but because of national environmental policies and industry profits and other reasons, the industry has become less and less.
Q:How is the charcoal burning out
Moisture contentBecause charcoal is a strong absorbent material, so in the process of piling up, it will absorb the moisture in the air, so that their water content increased. Therefore, the size of the moisture content of the water itself has no effect on the quality, but the customer requires the lower the moisture content of the better, in order to enhance its economic value. Generally speaking, just baked charcoal moisture content are less than 3%.Two, volatile fraction (volatile content)The volatile content depends 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%.
