How to analyze the two? 2. How to analyze the quality of a coal blending ratio? What is included in the analysis of both coal and coke? I’m asking for everyone’s help!!{:1_90:}
The overall coking efficiency is the percentage by mass of dry coke produced in the coking process relative to the mass of dry coal fed into the furnace. The metallurgical coke ratio refers to the percentage of metallurgical coke in relation to the total amount of screened coke. Its calculation formula is: Metallurgical coking ratio (%) = Qualified output of metallurgical coke (on a dry basis) (tons) / Total qualified output of coke (on a dry basis) (tons) × 100%
I believe that the quality of the blend derived from coal and coke analysis depends mainly on the various indicators of the blended coal, as well as the properties of the coke in both cold and hot states. Of course, the strength of coke is also related to temperature control to a certain extent.
