Proximate analysis

The proximate analysis of coal separates the products into four groups: (1) moisture, (2) volatile matter, consisting of gases and vapors driven off during pyrolysis, (3) fixed carbon, the nonvolatile fraction of coal, and (4) ash, the inorganic residue remaining after combustion the proximate.

Proximate analysis

Coal analyses may be presented in the form of “proximate” and “ultimate” analyses, whose analytical conditions are prescribed by organizations such as the astm a typical proximate analysis includes the moisture, ash, volatile matter, and fixed carbon contents. The proximate analysis gives moisture content, volatile content (when heated to 950 c), the free carbon remaining at that point, the ash (mineral) in the sample and the high heating value (hhv) based on the complete combustion of the sample to.
