What Is the Proximate Analysis of Coal? Proximate analysis reveals the quality and precise chemical composition of a coal sample. This analysis examines four factors: moisture, volatile compounds, ash content and fixed carbon. Information revealed during proximate analysis impacts coal prices and determines the most efficient use for each shipment.
Proximate analysis is a vital quality control parameter for coal and coke. This analysis covers the estimation of moisture, volatile matter, fixed carbon, and ash. Proximate analysis is extremely crucial from the point of view of buying/selling of coals.
Ultimate analysis tests produce more comprehensive results than the proximate analyses. SGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference).

* GCV of lignite on 'as received basis' is 2500 –3000 Analysis of Coal There are two methods: ultimate analysis and proximate analysis. The ultimate analysis determines all coal component elements, solid or gaseous and the proximate analysis determines only the fixed carbon, volatile matter, moisture and ash percentages.

Chapter 7 COAL If we as a nation are to benefit in the future from our enormous, low-cost coal reserves, a variety of efforts are necessary to (1) develop and demonstrate new "clean coal" technologies; (2) reduce uncertainty over environmental regulation and allow electric power
At Standard Labs, we provide ultimate and proximate coal analysis to determine coal's energy value. Because so much depends on coal's heating ability, ultimate and proximate analysis provide invaluable information about chemical composition. Proximate analysis parameters include sulfur, moisture, volatile matter, ash, and fixed carbon.
In coal utilization: Coal rank …of tests, collectively called the proximate analysis, that determine the moisture content, volatile matter content, ash content, fixed-carbon content, and calorific value of a coal.
The STA8000 Simultaneous Thermal Analyzer (STA) is able to analyze coal and coke to obtain Proximate Analysis data – volatiles, fixed carbon and ash – using 10 to 100 milligram samples. This paper demonstrates this utility using standard coal and coke samples. Introduction Proximate analysis has long been used to determine the rank of coals by
