Embodiment
Coking coal：Also referred to as metallurgical coal, also known as coking coal.It is the one of medium and low volatile moderate cohesive and strong cohesive property
Bituminous coal is planted, coking coal is, the appellation of coking capacity good bituminous coal higher to degree of coalification in Chinese Coal Classification national standard.Coking coal
It is medium grade metamorphic bituminous.Because caking property is strong, the high-quality coke that intensity is big, lumpiness is big, intensity is high, crackle is few can be produced, is refining
Burnt best raw material.Degree of shrinkage is small during coking coal independent coking, and the bulbs of pressure are big, is difficult to release from coke oven, and fragile
Coke oven, so, to improve operating condition, must improve burnt to appropriate bottle coal, rich coal or lean coal etc. is incorporated in coking coal during coking
Carbonaceous amount, and coal for coking resource can be expanded.
/ 3rd coking coal：/ 3rd coking coal are the transition coals between coking coal, rich coal and bottle coal.Waved with middle height
The heavy caking coal of hair point.During coking independent with this coal, the coke that meltbility is good, intensity is higher can be generated.During coking, three
The amount of allocating of/mono- coking coal can be fluctuated in relative broad range, can obtain the higher coke of intensity, and this coal is also good
Basic coal in coke making and coal blending.
Rich coal：Rich coal is one kind of bituminous coal, and degree of coalification is higher, is the weak caking property of medium volatile matter and middle high volatile
Coal, its volatile matter is in 25%-35% or so.Rich coal is also one kind of coal for coking, and more for coking, coking capacity is good, produces
Char strength is higher, but wears no resistance, easy expansion damage stove when individually with its coking, therefore the mixing of many and other bituminous coal makes
With.Rich coal maximum thick ness of plastic layer y>25 millimeters.With the coal facies ratio of other coal ranks, rich coal typically has higher sulfur content.
Gas rich coal：A kind of volatile matter and gelatinous layer all very high strong cohesive property rich coal classes, what is had is referred to as liquid fertilizer coal.Coking
Substantial amounts of gas and liquid chemical product can be produced during independent coking between rich coal and bottle coal.Gas rich coal is best suited for
High-temperature retorting manufactures coal gas, it can also be used to coke making and coal blending, to increase chemical products yield.Loping District, Northeast Kiangsi and Zhejiang Chang Guang coalfields are
China's gas rich coal Typical Mining.
Lean coal：Lean coal is one kind of bituminous coal, and degree of coalification is higher.Volatile matter is less, and caking property is weak, can individually coking, category
Coking coal.A considerable amount of gels can be produced in process of coking, Y value is typically in 6-10mm or so.Generated with single coal coking
Coke, meltbility is poor, it is easy to which fragmentation, wearability is small, but lumpiness is big.The leaning agent of coal-blending coking is commonly used for, to reduce coke
Crackle, improve coke wearability and lumpiness.Also serve as the raw material of fuel and gasification.
Anthracite：Anthracite, is commonly called as anthracite or anthracite.It is the maximum coal of degree of coalification.Anthracite fixes carbon content height, waves
Hair point low yield, density is big, and hardness is big, and burning-point is high, is not smoldered during burning.Black is hard, there is metallic luster.Will not with fat friction
Stain, fracture into conchoidal, during burning, flame is short and few cigarette.Noncoking.General phosphorus content is more than 90%, and volatile matter is 10%
Below.Without thickness of colloidal matter layer.Calorific value about 6000-6500 kilocalories/kilogram.Sometimes volatile content it is especially big to be referred to as half smokeless
Coal；Special small referred to as high anthracite.
Bottle coal：Bottle coal is a kind of relatively low bituminous coal of degree of coalification, is not bonded or micro- tool caking property.In stratiform coke oven not
Coking.Flame is short during burning, resistance to burn.Completely cut off air heating, a large amount of coal gas can be produced.Some bottle coals can also be used to refine oil and carry
Take industrial chemicals.As the bottle coal that reserves in coking coal are maximum, mostly with low ash, low-sulfur the characteristics of, coal-blending coking can show
The harmful components such as ash, the sulphur of reduction coke are write, while reducing coking pollutant emission, alleviate shadow of the metallurgical production to atmospheric environment
Ring, be the coking coal of most potentiality to be exploited.In coal-blending coking, rich coal is most strong to the containing ability of bottle coal, and bottle coal proportioning should
It is controlled by by radix of rich coal.Significant change occurs for the increase matched with bottle coal, coke items stomatal parameters, and coke is hot
Matter is progressively deteriorated and in the presence of drastically deteriorating a little, bottle coal participates in the influence of coking STRENGTH ON COKE thermal property mainly by changing stomata knot
What structure was realized.
Meager lean coal：High to degree of coalification in Chinese Coal Classification national standard, volatile matter is low, and caking property is (see the bonding of coal
Property) bituminous coal between meager coal and lean coal appellation.Standard regulation, the dry ash free basis volatile matter Vdaf of meager lean coal>10
~20%, adhesive index>5~20.Meager lean coal produces very small amount gel in heating, it is impossible to is individually smelt block coke, is
Transition coal between coking coal and mill coal.It is typically used as industry or domestic fuel, it can also be used to manufacture formcoke from cold briquetting.Work as refining
Adhesion component is sufficient in burnt mixed coal, and during lean coal insufficient supply, can be incorporated a small amount of meager lean coal.
