Book excerpt: Excerpt from Specific Gravity Studies of Illinois Coal The Object of this bulletin is to present the results of a study of (1) the effect of moisture upon the specific gravity of coal, and (2) the methods of determining the specific gravity of coal. The commercial aspects of the problem are discussed, and values are given for the specific gravity of coal from many of the mining districts of the State of Illinois. The specific gravity of bright and dull coal is also considered. The investigation was carried on under the direction of Professor H. H. Stock of the University of Illinois, who suggested the problem and whose advice and criticism were of great value. Experiments were conducted in the laboratories of the Department of Mining Engineering of the University of Illinois, and field trips were made to the Vermilion county coal field, where samples of coal were collected from a number of mines. Other samples were obtained from various sources. The author is indebted to Professor E. A. Holbrook of the Department of Mining Engineering of the University of Illinois for assistance in securing sam ples of coal and for valuable suggestions and criticisms during the prog ress of the work; and also to Professor S. W. Parr of the Department of Chemistry of the University of Illinois, and Mr. Fred H. Kay, of the Illinois State Geological Survey, for advice.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Sulfur Reduction of Illinois Coals, Vol. 1: Washability Studies The potential reduction in sulfur (and ash) that can be obtained with a coal can be determined by making float - and sink (washability) tests with the coal in a laboratory. As described in more detail later in this report, this process is essentially one of determining the weight percentages and chemical compositions of the material that is collected from liquid baths of different specific gravities The percentage of coal that floats is commonly called recovery, and the mater ial that sinks is often called reject. A commercial preparation plant cannot provide as precise a separation of float - and sink products as that obtained in the laboratory.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Chemical Study of Illinois Coals In the fifteen years which have intervened since the first study was made of the chemical composition and properties of the coals of the State, notable advancement has been made in methods of procedure in connection with such work. This result has naturally followed our increased knowledge and better understanding of the properties of this complex substance, but especially has it been caused by the marked changes which have occurred in the methods of purchasing coal, especially on the part of large consumers, whose contracts are based on specifications as to quality. This method has led to a care ful scrutiny of all processes yielding factors which enter into the final settlement. Small errors in large consignments may result in serious injustice to one or the other of the parties involved. These studies, therefore, have been especially directed to sampling, the conservation of moisture, and the determination of ash and of heat values.

This book was released on 2018-02-18 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Modification of Illinois Coal by Low Temperature Distillation Concerning the waste of the fuel supply, there are broader reasons for economy than the mere selfish demands of the indi vidual or corporation interested. Notwithstanding the fact that the coal fields of the United States are extensive, the coal supply is not inexhaustible. Campbell1 states that at the present rate of increase, the available coal fields of this country will be used up in ninety years, but if the rate of consumption of 1905 remains constant the fields will last four thousand years. It is hardly possible that the great activity which has so characterized the past twenty-five years, in the building of railroads, steamship lines, and factories will be as marked in the future as it has been in the past. There will be, however, a constant increase in the con sumption of coal unless some new source of power is developed. It does not seem probable that the rate of increase will be materi ally affected for a great many years to come; hence, Campbell estimates that four hundred years will be nearer the truth than four thousand. The sources of loss are mainly two; one is found in wasteful methods used in the mining, and the other in the combustion of coal. Although it is not within the province of this work to dis cuss the present day methods of mining, it might be well to men tion the fact that from 40 to 60 per cent of the coal is left in the mine in the form of walls, pillars, roofs, dust, etc. In the matter of economic combustion, the advancement has been almost entire ly on the mechanical side as illustrated in the modern stokers, improved combustion chambers, the sizing and washing of coal, etc. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Sulfur Reduction of Illinois Coals: Washability Studies; Part 2 Part 1 of this study indicated that the washability characteristics of Illinois coals crushed to a maximum size of 1 inches usually did not vary significantly from the washability characteristics of the same coals when crushed to a maximum size of inch. Because the results with the two size ranges were similar and since the -inch maximum size would allow the use of a smaller quantity of coal for the washability tests, a -inch maximum size was used for all tests described in this report. The minimum size of 28 mesh (tyler screen series) was selected because (1) it was considered the finest size of Illinois coal that could be readily separated by gravity methods, and (2) only a small proportion of the coal would be finer than 28 mesh after crushing and screening in stages to the maximum size of inch. During Part 1 of the investigation, a l-ton sample of raw coal, which generally was sampled in 20 to 30 increments through most of one shift of Oper ation, was obtained from the tipple; a few samples were obtained from the pit. None of the samples was considered representative of a mine's output. A differ ent method of sampling was used for the study described in this report. Instead of obtaining a l-ton sample, an approximately 80-pound sample, which will be referred to subsequently as a column sample, was cut from each of three freshly exposed coal faces at separate working areas of a mine. This procedure pro Vided a total sample of about 240 pounds per mine. Although these samples may not be representative of the output of the mine either, they are considered to be superior to those obtained by the tipple or pit-sampling procedure used in Part 1 of this study. Pace - channel samples, from which mineral bands of more than inch in thickness were excluded in accordance with U. S. Bureau of Mines procedures (holmes, also were cut from the same general locations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Composition of the Ash of Illinois Coals Table 1 is a tabulation of analyses and sample descriptions assembled from the analytical files of the Survey. The table is arranged by the counties from which the coal samples were collected. Where available, analyses of ashes from face samples are shown first, followed by analyses of various prepared products. Since the analyses for each county represent samples of coals of different size, gravity, etc. And since coal preparation influences the ash composition, it is not possible to arrive at reliable county averages.
