Key Definitions
Proximate Analysis: A standard analytical procedure (ASTM D3172) that determines the moisture, volatile matter, fixed carbon, and ash content of a coal sample. These components are used to characterize the coal's rank and combustion behavior.
Ultimate Analysis: A standard analytical procedure (ASTM D3176) that determines the elemental composition of coal: carbon, hydrogen, nitrogen, sulfur, and oxygen (usually calculated by difference). This analysis is essential for calculating heating value and emission factors.
As-Determined Basis (adb): The condition of a coal sample as received and analyzed, with its inherent moisture content. Results are often converted to other bases (e.g., dry, dry ash-free) for comparison using the practices in ASTM D3180.
Hardgrove Grindability Index (HGI): A measure of coal's resistance to pulverization, determined by ASTM D409. It is an empirical index crucial for designing and operating coal pulverizers in power plants.
