Problems in coal quality analysis
Thread Content
I noticed that the coal quality analysis reports mention infrared and coulombic methods for determining the sulfur content in coal, but the data obtained from these methods differ significantly! I would like to ask everyone about the differences between these two analysis methods? In actual calculations, which method’s data is used as the basis for the computation?
The Coulomb method should be accurate, while the infrared method is indirect but relatively fast. The Coulomb method involves directly burning sulfur to produce sulfur dioxide and then conducting measurements.
Are the results of the two testing methods significantly different?
