Moisture is also determined in the ADB analysis. (Madb) The ADB analysis is corrected to the field conditions by using the Moisture content in the first sample.

What does ARB stand for in coal specification? ARB stands for "As-Received Basis" in coal specification. This means that the coal sample is analyzed without any alteration, including its moisture content. ARB is often used to evaluate the energy content and other properties of coal as it is actually delivered.

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 …

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 weight as the basis ...
was found that the ultimate analysis of coal is the best predictor. Begum, Chakravarty, and Das (2019) used proximate data and coal's spectral reflectance data to estimate the GCV of coal. The models were created using the MLR approach. Ash, moisture, and volatile matter content are the proximate analysis of coal results.
A 600 MWe coal‑fired power station operating at 38% efficiency and 75% overall availability will consume approximately: – Bituminous coal (CV 6000 kcal/kg NAR*): 1.5 Mt/year – Brown coal (CV 2250 kcal/kg NAR*): 4.0 Mt/year *Net As Received
The objective of ultimate coal analysis of coal is to determine the amount of fixed carbon (FC), volatile matters (VM), moisture, and ash within the coal sample.
