Paperback. Condition: New. Print on Demand. This book offers a comprehensive overview of mine samples of Illinois coals collected from 1912 to 1921 by the author for a chemical study by the State Geological Survey. The study began in 1912 and was carried out in four parts. The first part dealt with selecting and collecting mine samples, the second part with chemical analysis, the third with heating value and other properties of the coal, and the fourth with proximate and ultimate analyses, calorific value, and the fusibility of ash. The proximate analysis of coal includes the determination of moisture, ash, volatile matter, and fixed carbon. The ultimate analysis includes the determination of sulfur, hydrogen, carbon, nitrogen, and oxygen. The analyses were made on a large number of mine samples. This book presents proximate analyses of 1511 face samples and ultimate analyses of 289 face samples. Arranged by county and then by mine and bed, each entry provides moisture, ash, volatile matter, fixed carbon, sulfur, hydrogen, carbon, nitrogen, oxygen, and calorific value (British thermal units per pound of coal). The detailed analyses presented in this book provide valuable data for understanding the chemical composition of Illinois coals. This information is essential for assessing the quality and suitability of these coals for various applications, such as power generation, industrial processes, and domestic heating. The author's meticulous approach and comprehensive analysis make this book a valuable resource for researchers, coal industry professionals, and anyone interested in the history and composition of Illinois coals.
