Experiment and application of middle and high sulfur lean coal blending coking technology
ZHANG Ligang
Abstract：In order to expand the coking coal resources and reduce the cost of coal blending,taking the middle and high sulfur lean coal as the test sample,which is taken from No. 10 coal seam of western areas of Weibei coalfield in the southern of Erdos Basin.The middle and high sulfur lean coal contains low ash,its bond index and thickness of plastic layer is higher than that of generally lean coal,the inert and alive of petrography is close to 2,and the coking property is well.Through the coking test of middle and high sulfur lean coal,simulated coal blending of coal petrography,industrial coke oven coking test,verify the feasibility and determine the optimizations of middle and high sul-fur lean coal blending coking.The results show that middle and high sulfur lean coal can be used in coal blending for coking,the blending content of middle and high sulfur lean coal should be controlled below 10%,and high content of strong caking index blending coal can en-hance the thermal state index of coke.According to coal blending coking in industrial application of middle and high sulfur lean coal,show that using middle and high sulfur lean coal coking can produce quality qualified coke blending ratio of 3%~7%,expand coking coal re-sources and reduce the cost of blending coal using middle and high sulfur lean coal coking.
