Coal assay - Wikipedia
Ash content may be determined as air dried basis and on oven dried basis. The main difference between the two is that the latter is determined after expelling the moisture content in the sample of coal Fixed carbon. The fixed carbon content of the coal is the carbon found in the material which is left after volatile materials are driven off.
