Paperback. Condizione: New. Print on Demand. This book presents an in-depth examination of the equilibration method for determining moisture levels in coal. The method, first proposed in 1932, is a widely used technique in the classification of coal by rank. However, the author's extensive research found that the method can yiel…d unreliable results when applied to high-moisture coals, such as those found in Illinois. The book delves into the history and development of the equilibration method, providing a clear understanding of its theoretical underpinnings. It highlights discrepancies in the results obtained by the author using the equilibration method compared to other established procedures. The author's findings challenge the accuracy of the equilibration method for high-moisture coals, raising concerns about the validity of coal classifications based on this method. The book concludes by emphasizing the need for a reliable method to determine moisture levels in coal, particularly for high-moisture coals. The author's research underscores the importance of accurate moisture determination in the classification of coal by rank, a crucial factor in determining its commercial value and appropriate use.
