Chapter 8 | Miscellaneous Analysis

The category of miscellaneous analysis encompasses element-related analyses—such as chlorine, forms of sulfur, forms of carbon, carbon dioxide (CO₂), major and minor elements in ash analysis, and trace elements in coal—as well as special tests—such as the determination of the calorific value, fusibility of coal and coke ash, free-swelling index, grindability, and plastic properties of coal. Other tests can be included in this category, but those listed are discussed here.
