Application of Air Concentrating Table for Improvement in the Quality Parameters of the Commercial Product “Jaret®”

Abstract

Dry deshaling of raw coal is a method which allows to limit the amount of rock grains in raw coal. The result of this process is the ability to achieve a significant improvement in the quality parameters (calorific value) of the commercial products. There is also the possibility to limit the total sulfur content and ash content in the produced commercial products obtained from raw coal. This is confirmed by the tests carried out by "Centre of Waste & Environment Management” of the Institute of Mechanized Construction and Rock Mining with applying an air concentrating table – FGX. This chapter presents the results of desulfurization and ash removal from the commercial product JARET®, obtained from the production process of the Coal Company "Janina" being a part of TAURON-Wydobycie S.A. The technological requirements of the dry deshaling process are also presented.
