Coal size degradation depends on strata sensing and grindability. Figure 1 shows a diagram of the main stages of a coal sample preparation for the study and providing the initial data for the design of a coal preparation plant. Figure 1. Diagram of data preparation for CPP design.

Improving the Properties of Mined Coal. Kentucky coal is improved by the partial removal of the impurities—sulfur and ash. The cleaning process to remove impurities from the coal is often called beneficiation, coal preparation, or coal washing.. In general, coal cleaning is accomplished by separating and removing inorganic impurities from organic coal particles.

Coal Gasification: It bypasses the conventional coal burning process altogether by converting coal into a gas. With integrated gasification combined cycle (IGCC) systems, steam and hot pressurized air or oxygen combine with coal in a reaction that forces carbon molecules apart. The resulting syngas, a mixture of carbon monoxide, hydrogen, CO 2

Earlier coking coal was only washed as it was used in steel manufacturing with an ash content of 17-18 % but new environment regulations has put restriction on high ashcontent coal in power and other industries which necessitates the priority of washing non coking coal also. Washing is carried out to reduce the ash content, and to lower the ...

Most of the coal presently being consumed is by direct combustion of fi nely pulverised coal in large-scale utility furnaces for the generation of electric power. Currently, the cleaning of the majority of run-of-mine coal is con-ducted by heavy medium separation, jigs and chemical fl otation. ese techniques use water as a separation medium.
