How is coal GCV calculated? The results for intrinsic properties and the gross calorific value are given in table 1. GCV= 7115.197 – 123.971*M – 81.3121*A + 20.7421*FC, Where GCV in kcal/kg and moisture, ash, fixed carbon in air dried percentage basis. How do you calculate GCV and LCV?
Washery products with a gross caloric value (GCV) <2200 kcal/kg are washery rejects. • GCV is determined on an air-dried basis and reported on 40°C and 60% RH (relative humidity) in accordance with IS-1350 (Part-II), 1970. • The equivalent ash + moisture percentage for washery rejects may be around 65%.
Pada umumnya, terdapat 2 metode analisa yang digunakan untuk mengetahui kualitas batubara yaitu Air-Dried Based (adb) dan As Received (ar).

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 ...

A calculation is made as if the coal was only composed of volatile matter and fixed carbon (Thomas, 1992). Usually denoted as "daf" or "DAF." Dry, mineral matter-free basis: Data or results are calculated …
(i) For a given sample, ADB method gives the highest GCV value followed by EB method. The TMB method gives the lowest GCV value among the three methods. (ii) GCV on ADB basis gave undue advantage to the supplier since moisture present in coal, i.e., the sample, gets dried in the process for determination of GCV for payment to the

Coal Specifications. We exclusively trade thermal coal of Indonesian origin and offer three main calorific values – GAR 4200 kcal/kg, NAR 4700 kcal/kg and NAR 5500 kcal/kg.
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.
A moist ash free basis is an attempt to calculate the CV in situ with the true Inherent Moisture, which can only be estimated by using the Equilibrium Moisture EQM for ASTM or Moisture Holding Capacity MHC for ISO (see Section 3.4.2.1 starting on page 50 for more details).

In this study, the gross calorific value (GCV) of coal was accurately and rapidly determined using eight artificial intelligence models based on big data of 2583 observations of coal samples in the Mong Duong underground coal mine (Vietnam). Accordingly, the volatile matter, moisture, and ash were considered as the key variables …
Calorific value is the heat energy released per unit mass of fuel burned as shown by Formula F7.1. Gross calorific value, or higher heating value (HHV), is the total heat released making no allowance for the latent heat required to vaporize the liquid water produced by the combustion process.Hence it is a theoretical parameter and is rarely …
