1.. IntroductionCalorific value is an important property, indicating the useful energy content of coal and, thereby, its value as fuel. Heating value is a rank parameter, but is also dependant on the maceral and mineral composition (Hower and Eble, 1996).A number of equations have been developed for the prediction of gross calorific value …
GAR adalah Gross Caloric Value (GCV) dalam As Received Basis (ARB). Pada umumnya dalam ADB (dalam kalori GAD), sehingga harus dikonversikan dahulu ke As Received Basis (ARB).

Four different types of coal collected from four different sources were analysed for their proximate analysis, GCV and combustion behaviour analysis by TGA. Further, different combustion performance characteristic parameters were estimated and correlated with the proximate analysis parameters. ... {1/2}) is the corresponding time …
The gross calorific value (GCV), also known as the higher heating value (HHV) of coal is the amount of heat emitted upon complete combus-tion of coal. The GCV of coal is used to estimate various technoeco-nomic parameters such as boiler eficiency, combustion …
ADB - Air-Dried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (dry-basis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB - As-Received Basis. In coal sample analysis, ARB puts all variables into consideration and uses the total ...

What is ADB and ARB in coal? ADB – Air-Dried Basis. In coal sample analysis, ADB neglects the presence of moistures other than inherent moisture while DB (dry-basis) leaves out all moistures, including surface moisture, inherent moisture, and other moistures. ARB – As-Received Basis. It provides a rough estimate of the heating …

– where M is % Moisture, H is % Hydrogen, O is % Oxygen (from ultimate analysis*, also As Received). *Ultimate analysis determines the amount of carbon, hydrogen, oxygen, nitrogen & sulphur. For typical bituminous coal with 10% M and 25% Volatile Matter, the differences between gross and net
Analysis may be determined by X-ray fluorescence (XRF) (Fig. 6.7), or inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption …
Gross calorific value (GCV) is an important characteristic of coal and organic shale; the determination of GCV, however, is difficult, time-consuming, and expensive and is also a destructive analysis.
The ADB analysis is corrected to the field conditions by using the Moisture content in the first sample. The HHV, the proximate analysis and the Ultimate analysis are all …

The result obtained is the GCV of the analysis sample at constant volume with all the water of the combustion products as liquid water, and is usually expressed in J/g (or kJ/g, MJ/kg), cal/g (or kcal/g, kcal/kg). ... ADB to Dry Basis conversion of GCV. DB GCV % = (100/100-IM%)x ADB GCV. Conversions – Units.
Occasionally for gas fuels calorific value is quoted on a volumetric basis (Formula F7.2) having units of either kJ/m 3 or kl/scm. The scm (standard cubic meter) is the amount of gas that would occupy 1 m 3 at the ISO pressure and temperature of 101.325 kPa and 288.15 K respectively. Formula F7.3 shows how the number of scm present in a volume of gas …
