Application in coking production:
1. Evaluation of pre-purchased coal: judge the real quality of pre-purchased coal from the two aspects of metamorphism degree and coal and rock composition, whether it is a typical coal, etc.Combined with the conventional index can guide the coal purchase scientifically;
2. Check the incoming raw coal: it can quickly and accurately identify the composition of single mixed coal and coal-rock activity-inert ratio, and comprehensively and scientifically evaluate the coal quality;Note: according to incomplete statistics, every year only one item, the domestic enterprises lost a staggering number, as little as one million, more than one hundred million yuan;
3. Guide reasonable stacking in coal yard: make use of the principle of similar vitrinite reflectivity distribution and similar coal quality to reasonably arrange stacking in coal yard to prevent the unknown secondary mixed coal in the factory from causing large fluctuations in production;
4. Monitor the ratio of coal entering the furnace: get the true proportion of "active matter" with different coking characteristics, without being confused by the appearance of "surface coal proportion".Prevent large fluctuations in coke quality and mismatches and missing matches in other production links;, can effectively stabilize coke production
5. Fine coal and rock blending: guide coal blending from the perspective of coal petrology, and conduct coarse refining ratio operation to save huge cost and reduce waste;
6. Detection of pore distribution of coke: reversely deduce the reasons for change in coke quality, verify the rationality of "formulation" of ratio, and compare the influence of different coal blending on coke quality, etc.;
7. Coke optical structure test: predict the coke forming mechanism and the quality of various coal sources, so as to achieve the goal of the most refined and cost-saving coal blending;
