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:Activated carbon can really dehumidification
Throw into the water, will be a lot of blisters, like a sponge absorbent
Q:What are the signs of coal and gas outburst?
In the process of underground mining, coal and rock is often a moment from coal and gas spewed out, the phenomenon that the coal and gas outburst, referred to as "outstanding". Coal and gas outburst accident will not only cause the working face and ventilation system damage, while a large number of coal and gas to discharge at high speed that may also be full of roadway, causing suffocation and burning gas explosion, and coal (rock) embedded in the accident.
Q:Well log interpretation
The coal seam has the obvious characteristic in the well logging curve: "four high" characteristic: the resistivity is high, and the change scope is big, the sound wave time difference is big, the transmission speed is slow, the compensation neutron is big, the well diameter enlargement is big
Q:The difference between ginger and roasted ginger ginger charcoal.
Ginger Shizai in "Shen Nong's herbal classic", the processed products of ginger first recorded in Chinese "typhoid fever". The Song Dynasty, "Tai Sheng Hui Fang" contained in the ginger in "gun", and a "carbon gun" ginger charcoal. We can think of ginger charcoal from the Song Dynasty as a product of dried ginger. The Ming Dynasty in the "preparation" law of Miao Xiyong pointed out: "if the ginger postpartum blood deficiency fever and bleeding are fried black, gun powder Hanxie Wenzhong, the management of lung Ziou students". "Pointed out:" in the "compendium of Materia Congyuan ginger ginger black gun that posterity banthine gun is pungent ginger, if processing diminished, too, nature does not exist, that the bitter ginger charcoal, not spicy, the frivolous is not real, and not the function etc.". The "national processing standard of traditional Chinese medicine" specifically to distinguish the two: "gun Jiang Wen in the cold, abdominal pain, vomiting and diarrhea for spleen deficiency. Ginger carbon temperature by bleeding. Attending vomit blood due to Yin deficiency". So that the roasted ginger charcoal should be two kinds of different processed products of Rhizoma zingiberis.
Q:What is the role of ordinary charcoalCharcoal residue of jujube wood
Industrial field1 metallurgical industryThe charcoal smelting pig iron generally has the fine grain structure, the casting is close, does not have the crack the characteristic, uses the charcoal production pig iron to contain the impurity to be few, is suitable for the production high quality steelIn the production of nonferrous metals, charcoal is often used as surface flux, which can not only reduce the spatter loss of molten metal, but also reduce the gas saturation in the meltA large amount of charcoal is also used to produce crystalline silicon, but the production of crystal silicon with charcoal ash should not contain carbon head and too much.
Q:How to test coal
(1) free water and combined water in coalThere are two types of water in coal according to their different forms. Free water is based on the physical adsorption state in coal particles and coal particles attached to the capillary inner surface of the water; combined water is also called crystal water is combined with mineral water in the coal chemical way. Crystalline water, such as calcium sulfate (NaSO4.2H2O) and aged soil (AL2O3.2SiO2.2H2O). Free water in 105 ~ 110C temperature after 1 to 2 hours can be evaporated, and the crystallization of water is usually more than 200C in order to decompose precipitation.In the industrial analysis of coal, only the free water is measured.
Q:What is the bulk density of activated carbon?
Activated carbon, activated carbon. It is a black powder or lump, granular, honeycomb amorphous carbon, also has arranged crystal carbon.
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:What is engineering coal
2 gasification. Gasification refers to the conversion of industrial or civil fuel as well as chemical synthesis of raw materials.3 cryogenic distillation. Low temperature tar and low temperature coke oven gas can be prepared by low temperature carbonization of coal or oil shale at the temperature of 550 DEG C.4 hydrogenation liquefaction. The coal, the catalyst and the heavy oil are mixed together, and the organic matter in the coal is destroyed at high temperature and high pressure, and the hydrogen is converted into low molecular liquid and gaseous products.
