Variability and Correlation in Raw and Clean Coal

These sequences are subsequently modified by coal preparation, coal trans- portation, coal blending and sulfur emission control. Moreover, the sequence for one coal data set cannot be assumed to be applicable to other coals. Coal fired utility plants burn raw (unwashed) coal, clean (washed) coal, or a

Coal Preparation and Geostatistics — A Blend of

Recently interest has developed in combining geostatistics and coal preparation plant simulation to predict clean coal qualities (Armstrong et al. 1989). The basic concept is that geostatistics would provide statistically realistic models of recovery, ash content, sulfur content, etc. of the coal deposit for each washing (separation) density.

coal cleaning. The recovery of clean coal or the separation into two or more size fractions can be radically different from mine to mine, even when the same coal bed is mined. The accuracy of cost estimation, but especially the quality of clean coal, is highly dependent on the user's knowledge of the characteristics of the coal to be cleaned.

Preparation and Characterization of the Glycerol

The molasses embedded hybrid coal (Hybrid Coal by Korea Institute of Energy Research; HCK) was previously proposed as an attractive alternative to low-rank coals that tend to show low calorific values and high CO2 emissions. HCK was synthesized by mixing molasses with a low-rank coal to enhance its heating value. Nevertheless, food ethics regarding molasses additives still have impeded its
