Coal Calculations | Mining | SGS
The weight percent of the + ⅜” coke equals the CSR. Most blast furnaces will require a coke with a CSR greater than 60 and CRI less than 25.SGS is committed to providing accurate, cost effective blast furnace coke analysis for your operation. SGS is the world leader in coal and coke analysis and testing.
Coal Conversion - an overview | ScienceDirect Topics
Modeling coal conversion processes is a very complex topic. The main conversion steps of pyrolysis and char consumption are characterized by numerous phenomena, which have to be addressed by coal conversion models. Often, these models focus on one conversion step, describing either coal pyrolysis or char consumption.
