Indian Standard IS 1350-1 (1984) - Methods of Test for Coal and Coke - Part 1: Proximate Analysis. This Indian standard specifies a method for determining the proximate analysis of coal and coke, including moisture, ash, volatile matter, and fixed carbon. The GCV can be calculated from the results of the proximate analysis.

Proximate Analysis of Coal and Coke by Macro Thermogravimetric Analysis1 This standard is issued under the fixed designation D7582; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.

 — Summary. The proximate analysis of coal separates the products into four groups: (1) moisture, (2) volatile matter, consisting of gases and vapors driven off during …

 — Fixed carbon is a measure of the amount of non-volatile carbon remaining in a coal sample. It is a calculated value determined from other parameters measured in a proximate analysis, rather than through …

 — 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 analysis of coal is presented as a group of test ...

 — The most common coal analysis is proximate analysis. It is used on coals during exploration, mining, and preparation. Four different parameters are measured from one sample in a proximate analyzer, which is an automated instrument. ... Standard methods for proximate analysis are shown in ASTM D3172-07a (American Society for …

To utilize coal more wisely and effi ciently, accurate estimation of coal parameters in the proximate analysis is essential, which is always the fi rst stage of coal assessment. The …

 — The application of TG for coal analysis dates back almost as far as the techniques themselves, the first attempt to investigate the volatile matter yield of coals was presented in 1930 [14]. The direct comparison of proximate analysis results, obtained using standard and TG approaches, is presented in [15]. The thermogravimetric procedure ...

 — The data set (see Table 1) comprising constituents of the proximate and ultimate analyses as also the corresponding experimentally determined GCVs (kcal/kg) of 79 coal samples obtained from the mines located in the six prominent coal producing regions in India and supplied by the CFRI, Dhanbad, India, has been used for the …

 — India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal. Several methods are available to …

 — If you wish to learn more about Difference between proximate and ultimate analysis of coal,Proximate analysis of coal provides information on the ash, moisture, volatile matter while Ultimate analysis of coal provides information on the elemental composition, ranking of the coal, and heating elements of the coal.

 — Coal commonly originated in two major phases, i.e., organic and inorganic phases that may affect the calorific values of coal during formation (Cheng et al., 2014;Dai ...

 — The coal ranks are wide and the properties vary with the coal rank to a great degree.
