According to Dulong's formula gross calorific value of a fuel is; GCV = ((35.5 x C + 114.8 x H + 9.5 x S - 14.5 x O) x 1000) / (100 x 4.1868) Each multiple of carbon, hydrogen and sulphur ...

Geological Survey Coal Quality database, [6] are analyzed, shows the regression analysis of proximate and ultimate analysis of coal samples. The R2 value of 0.99 shows that there is an overall good fit of data with 95% confidence level. Hence, the best-correlated multivariable equations, between the various mentioned parameters

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.

Dulong formula, the gross calorific value, moist basis, of the coal. 3. The proximate analysis of coal is: Moisture 2.4%, Volatile Matter 29.4%, Fixed Carbon 58%, Ash 9.7% and Sulphur 0.5%. Its gross calorific value is 7650 Kcal/Kg. Calculate proximate analysis and calorific value on a) Moisture free basis

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 …

models have been proposed to estimate the GCV of coal samples based on proximate analyses and/or ultimate analyses [2, 6, 7, 9–24]. The present study had two main purposes; the first one was to develop prediction models for GCV of coal using as-received basis proximate analysis results and the second one was to reveal the discriminative

In this method the proximate and ultimate analysis of coal is carried out to determine the radicals listed in (a) and (b) and inputs of (b) are used in formula (i) to calculate approximate CV. a. Proximate analysis: moisture %, ash%, volatile matter % and fixed carbon % by difference. Use : Fixed carbon gives a rough estimate of CV of coal. b.

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 ...

determined by carrying out proximate analysis and gross calorific value (GCV) by using bomb calorimetry. The results for intrinsic properties and the gross calorific value are given in table 1. Correlation analysis was carried out to analyze the individual effect of moisture, volatile matter, ash and fixed carbon on the gross calorific value (GCV).

utilities usually get coal from multiple sources and coal is priced essentially on the basis of gross calorific value (GCV). During combustion, GCV contributes only to the maximum possible heat release, though heat release rate is mostly controlled by coal proximate parameters i.e. ash, volatile matter, moisture and fixed carbon (Behera et al.

A new formula for calculating the calorific value of coal from its ultimate analysis has been obtained by regression analysis of a data bank consisting of data on 775 samples of U.S. coals of all ranks. It yielded zero average difference between observed and calculated values and a standard deviation of 129 Btu/lb (300 kJ/kg).

5.1.2 The results of proximate analysis are generally recorded as a percentage of the air-driedmaterial. The ash may be expressed on 'dry' basis. Volatile matter and fixed carbon may be expressed on 'dry'basis,, dry ash-free' basis or 'dry mineral free (drnf)' basis. Such figures are arrived at by calculation from the'air-dried'basis results. 6.
