Quality Control in Export Coal

This paper addresses the quality control problem faced by a coal mine of satisfying a specified minimum net calorific value (NCV) requirement for the coal loaded at an export harbour, by means of a control strategy on the gross calorific value (GCV) at the mine's wash-plant. From the NCV:GCV relationship a formula for the target mean GCV at the wash-plant is derived.

Quality Control of Coal with Elemental Analyzers

A huge amount of the worldwide traded stone coal is mined in China, USA, Russia and India. Compared to the large amount of mined coal the required sample volume for the characterization of coal, varying from a few mg up to 1 gram, seems unbelievably small. The characterization of coal is important for its quality assessment and further use.
