Issues related to the components of raw coal quality analysis
Thread Content
In the quality analysis of raw coal, should the sum of all components on equivalent bases (as received, on air-dry basis, on dry basis, ash-free basis) equal 100%? The main analysis focuses on internal and external water; the sum of ash, volatile matter, and fixed carbon should equal 100%. How are the various components converted under different benchmarks?
Theoretically, the sum of all components should equal 100%; in actual testing, if positive errors are not taken into account, this sum is less than 100%, as it is impossible to analyze everything.
Can the components under that non-cultivation baseline be converted into one another?
Is there a specific formula? Could you share it?
Do you want to convert the actual test data on a received basis? Refer to and search for GB/T 212-2008 \"Methods for Industrial Analysis of Coal\"
