Q:I was a major in geological engineering, in the practice of mineral petrology, the teacher asked, "the mineral composition of coal?" Is a mineral petrology, coal chemistry is not in, please master, senior students. Thank you: 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:What is coal dry base settlement: Base means that the result of the test is based on what kind of coal samples:

Q:How to use activated carbon to filter liquor: Look at the production of activated carbon dust in the process, must crush the material to remove dust, or dust too much, cleanliness is poor, it will cause pollution to the human body and the goods on the market, in order to reduce the cost of poor quality of activated carbon, no postprocessing, large dust, multi use dark bags, small hands up for carbon the use of dirty, dirty things cause two pollution. Recommend the selection of small carbon bag is a white breathable non-woven bag, feel no dust is not dirty products.

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:Anthracite is what kind of indicators?: Indicators of coal in this range are called anthracite: total water Mt (%) 4-6, dry base ash Ad (%) 10-15, dry ash free volatile Vdaf (%) 7-9,

Q:The standard Meizhi is what mean?: The standard Meizhi is calorific value per kilogram of 29 million 300 thousand coke coal

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 composition of coal: Volatile matter is also the main coal quality index, in determining the processing and utilization of coal processing and process conditions, volatile matter has an important reference. Coal with low coalification degree, more volatile. If the combustion conditions are not appropriate, high volatile coal combustion is easy to produce unburned carbon particles, commonly known as "black smoke" and produce more carbon monoxide, polycyclic aromatic hydrocarbons, aldehydes and other pollutants, thermal efficiency decreased. Therefore, the appropriate combustion conditions and equipment should be selected according to the volatile components of coal. The content of inorganic matter in coal is very little, which mainly includes water and minerals. Minerals are the main impurities in coal, such as sulfides, sulfates, carbonates, etc., most of which are harmful.

Q:There are several types of coal: Coal can be divided into anthracite, bituminous coal and ligniteIn our country, the bituminous coal is divided into three parts according to the indexes of ash, volatile matter, caking index and maximum thickness of the colloidal layer

Q:On behalf of the company to study the coal test, which can help me to explain the online test of coal each indicator of the process, thank you: Copy the following into a DOC file, print, slowly lookIndustrial analysis of coal 1The industrial analysis of coal, also called the technical analysis and practical analysis of coal, is the basic basis for evaluating the quality of coal. In the national standard, the industrial analysis of coal includes the determination of moisture, ash, volatile matter and fixed carbon. Determination of moisture, ash, volatile matter and fixed carbon in coal. Generally, the moisture, ash and volatile matter of coal are measured directly, while the fixed carbon is calculated by subtraction. Broadly speaking, coal industry analysis including coal - Determination of total sulfur content and calorific value of the whole industry, also called coal analysis.
