This document provides formulas for converting between different measurement bases for coal: air dried basis (adb), as received (ar), dry basis (db), and dry ash free (daf). The formulas show how to calculate ar from adb by factoring in total moisture (TM) and inherent moisture (IM). Db is calculated from adb by factoring only IM. Daf is calculated from adb by factoring IM and ash …
The relation between GCV at AD (as received basis) and ADB (air dried basis) and ARB (as received basis) can be calculated using the formula: GCV(ADB) = GCV(AD) - [H2O * latent heat of vaporization]

What is the relation between gcv at ad and adb and arb? The relation between GCV at AD (as received basis) and ADB (air dried basis) and ARB (as received basis) can be calculated using the formula: GCV(ADB) = GCV(AD) - [H2O * latent heat of vaporization] GCV(ARB) = GCV(ADB) / (1 - moisture content)
Coal ARB: ARB or the As-Recieve-Basis denotes the rough estimate of any kind of coal. On the other hand; Coal ADB: Air dried basis neglects the presence of moisture in the coal .
Various parameters of coal can be estimated from the Ultimate Analysis and Calorific Value determinations, using Seyler's formula, and other similar calculations (e.g. Dulong's formula).
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 is the most widely used basis in industrial applications. Ash content - Ash content is the non-combustible ...
