Exploration of high-volatile gas coal application in coal-blending coking
In order to extend the scope of coking coal resources,rationally and efficiently utilize different types of coal,and develop new coal resources that can be used for coke production,based on the coal blending scheme of Shanxi Coking Co.,Ltd.,the high-volatile gas coal with high caking and fluidity was selected,and its differences in coal property compared with gas coal and medium viscous coal in basic coal blending were analyzed.The influence of high-volatile gas coal on the quality of coal blending coke was investigated through the coking experiment of 40 kg coke oven.The results showed that,by substituting appropriate proportion of high-volatile gas coal for part of gas coal or medium viscous coal in basic coal blending,the coke quality was obviously higher than that of basic coke and the cost of coal blending was also reduced.
