    Oct 07, 2019 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 direct measurement (ASTM method D3172-07a; American Society for Testing and Materials, 2013, p. 492-493).Fixed carbon is the calculated percentage of material that was lost during …

  • Predictions of Gross Calorific Value of Indian Coals from

    Apr 11, 2019 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 predict GCV using either moisture content and/or ash yield or using entire proximate and ultimate coal analysis data.

    Oct 07, 2019 Total carbon: Total carbon in the ultimate analysis is the measured weight percent of carbon in a coal, including the carbon in volatile matter.It is determined using ASTM method D5373-08 (American Society for Testing and Materials, 2013, p. 628–636). Fixed carbon from the proximate analysis is a different value than total carbon from the ultimate analysis.

  • Prediction of gross calorific value of Indian non caking

    While proximate analysis gives a preliminary insight of the coal, gross calorific value (GCV) is an important parameter which is being routinely used at the power stations for assessing the heat rate, efficiency etc. GCV can be experimentally determined but several correlations have been developed to estimate the GCV from coal quality parameters.
