Abstract:

This paper comprehensively analyzes A type coking coal with methods of coal petrography reflectance detection,Gieseler fluidity measurement,coking test with single coal and coal blending coking test etc. The test shows that The G value,Y value and industrial analysis index of A type coal are similar with and even better than other coking coal of the same kind,but its micromaceral is abnormal,and the ratio between reactive and inert components is as high as 19.2,maximum fluidity is only 32ddpm,and the thermal intensity of the produced coke from the single coal is as low as 5.26%.
