Q:What is coal dry base settlement
(1) the ad: of air drying base is based on the coal sample with the air temperature in the equilibrium state;(2) drying base d: the coal sample under the condition of imaginary water as the reference;(3) received the base ar: the coal samples received as the basis;(4) dry ash free DAF: Based on the coal samples under the assumption of no water and no ash;(5) dry mineral free base dmmf.. As the basis of coal sample under the condition of no water and mineral.
Q:The development history of activated carbon
157 years, Claudius medical papers mentioned in the vegetable and animal sources prepared charcoal, for the treatment of various diseases.Chinese Li Shizhen of the Ming Dynasty (A.D. 1518-1593) edited by Compendium of Materia Medica mentioned in charcoal for treatment of diseases.In 1773, Scheler through a large number of experiments found charcoal adsorption capacity and adsorption of various gases.In 1777, the effect of charcoal heating and gas adsorption was reported, which led to the "condensation adsorption theory".In 1785, Scheler studied charcoal adsorption gas, the adsorption capacity of steam from the steam to a series of organic chemicals and a variety of aqueous solutions using charcoal decolorization, especially the production of tartaric acid commercial applications. This seems to be the first systematic consideration of the adsorption of charcoal on the liquid phase.
Q:The standard Meizhi is what mean?
Standard coal, also known as coal equivalent, has a uniform calorific value. China's per kilogram of standard coal calorific value of 7 million cards. The different varieties and different contents of energy are converted into standard coal with a calorific value of 7 million calories per kilogram according to their different heat values.Energy standard coal coefficient = the actual calorific value of some energy (kcal / kg) /7000 (kcal / kg)
Q:What are the uses of coal?
3) coal for building materials: accounting for more than l0% of the power coal, the largest amount of coal used in 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.
Q:Types of coal and how
Types of coalAccording to the classification Chinese coal, coal volatile, all coal is divided into lignite, bituminous coal and anthracite; for lignite and anthracite, respectively according to the characteristics of the degree of coalification and industrial use is divided into 2 and 3 categories; four stages, according to the >10%~20% bituminous coal volatiles >20%~28%, 28%~37 and >37% divided into low, medium, high and high volatile bituminous coal. As for the caking property of bituminous coal, it is distinguished by the bond index G: 0~5 is non caking and slightly caking coal; >5~20 is weakly caking coal; >20~50 is medium weak caking coal; >50~65 is moderately strong caking coal; >65 is strong caking coal. For the strong caking coal, and the plastic layer maximum thickness of Y>25mm or b>150% (for Vdaf>28% AoYa dilatation of bituminous coal, b>220% coal) into strong caking coal. In the name of coal type, taking into account the continuity of the new classification, still retain the gas coal, coking coal, lean coal, lean coal and weakly caking coal, non caking coal and long flame coal 8 coal.
Q:What is the difference between raw coal and standard coal?
1 tons of crude oil = 1.43 tons of standard coal1000 cubic meters of natural gas = 1.33 tons of standard coal1 tons of raw coal = 0.714 tons of standard coal3 of the energy converted to standard coal coefficient = some actual calorific value energy (kcal / kg) /7000 (kcal / kg) before the various energy conversion standard of coal, the actual average calorific value of the first direct estimates of various energy sources, and then converted to standard coal. The average calorific value, also known as the average calorific value, refers to the weighted average value of the measured calorific value of the energy of different species or varieties.
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:What is bituminous coal, coal tar distillation of the product is coke and coal tar
All kinds of coal asphalt according to its consistency can be divided into: soft coal tar and coal tar pitch. Two kinds of soft coal asphalt is coal tar in further processing, only part of naphtha and distillate oil and viscous liquid or semi-solid product. The hard asphalt is coal tar distillate oil, fractionated in oil and heavy oil that most of the oil and anthracene oil brittle solid products. Coal tar pitch can not be directly used for road construction, coal tar pitch available for soft coal tar anthracene oil back.
Q:The necessity of power coal washing
A coal is an important part of the coal industry x0d produced from coal mine or open-pit coal gangue, always contain a certain amount of. Because in the mining process, with the top and bottom rock gangue and crushed coal seam are often mixed with coal; and different thickness of coal seam with the thickness of the layer (clip in), floors, roof and floor rock properties and operation methods are different, the amplitude fluctuation of the gangue, and randomly mixed with coal, lead mine or open-pit coal ash has great fluctuation; especially with the modernization of the coal industry, coal mining, coal unit is difficult to implement rock well, can not be on the working surface of picking, will inevitably lead to decline in the quality of raw coal; in order to make full use of energy, low quality coal mining has gradually expanded. Therefore, wellhead coal is only a semi-finished products. For example, Liaoning Province Pure coal ash several opencast coal mine are low, 10.17.47%, when using a shovel mining, the average rate of coal gangue reached 24.44%, into the factory wellhead raw coal ash up to 27.10~41.9% (see table 6-1-1). In the actual production of open-pit mine, there is a part of the coal (particularly low rate generally less than 20%) of coal gangue, the gangue turned to the dump line, use a number of artificial out part of the coal. If all or most of the Department to the coal washing plant washing, is mine before the election, raw coal ash and gangue rate will far exceed the table 6-1-1 number. So I think. Used excavator bucket of open-pit coal out of coal and gangue is different than by a mixture of product sales do not have certain requirements on the quality of the coal units. So open-pit mine production of raw coal, so how well? The word rather produced from the mine coal containing There are 15~40% of the gangue, although its pure coal ash is 7~25%, but because of a large number of external ash, the original coal ash is about 13~50%.x0d
Q:The coal industry often crushed to the full combustion, its purpose is to
A, the coal industry often crushed, increasing the contact area of coal and oxygen, can make full combustion of coal, reduce coal waste, so the correct option.
