Quality Control in Export Coal
L. P. Fatti and T. J. Stewart Quality Control in Export Coal We shall call,tcv the 'target mean NCV'. Since, however, the mean NCV is not under direct control at the mine, PNcv needs to be further converted into a target mean GCV. This is achieved via a secondorder Taylor expansion of the righthand side of the formula (1), by taking
Quality Control of Coal with Elemental Analyzers
