Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Unit Coal and the Composition of Coal Ash A number of investigators have worked on various phases of this topic. Lord and Haas, who were no doubt the first in the field, have developed the idea that in any given type of coal, or perhaps, less broadly, in any given deposit of coal, there exists an initial substance, with certain uniformities as to calorific value, which might make it possible to calculate the heat units for any sample whose source as to locality was known.

Book excerpt: Excerpt from Coal: Its Composition, Analysis, Utilization and Valuation The data and descriptive matter given herein, are largely based upon private notes and upon information and material scattered through text-books, technical bulletins, and in original papers in technical and scientific journals. Much of this data is either inaccessible or in such a form as not to be readily applied or interpreted and hence is not likely to be utilized by those who have the most active interest in coal.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Contributions to the Study of Coal: A Proposed Simplification of the Parr Unit Coal Formula, Ash-to-Mineral Matter Correction in Coal Analyses, Unit Coal as a Basis of Coal Standardization as Applied to Illinois Coals When coal is burned, the mineral matter is converted into ash, involving changes in co'mposition and quantity and certain thermal effects. Of these, the loss in quantity due to the release Of water of hydration and to the conversion of pyrites to iron oxide, and the heat effect due to the combustion of the pyrites, are the most important. The heat effect and the quantitative effect due to the change of calcium carbonate to calcium oxide, although appreciable when considered by itself, may be neglected in calculations Of pure coal values,6 except in the infrequent cases of the occurrence of calcite in coal in quantities greater than 1 per cent. Other quantity and heat effects are so small that they may be neglected and yet not affect the calculation to an amount approaching the allowable experimental errors.

Book excerpt: Excerpt from Occurrence and Distribution of Potentially Volatile Trace Elements in Coal: A Final Report The chemical nature of coal ash has been amply summarized in recent review articles (francis, 1961; Ode, 1963; Nicholls, 1968; watt, 1968; and Magee, Hall, and Varga, which deal in part with trace elements. However, research on trace elements in coal ash has not been extensive because until now they have been of little more than academic interest and because they occur in such small amounts that their determination is both costly and difficult.

This book was released on 2018-03-08 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Fusibility of Coal Ash and the Determination of the Softening Temperature Although it is believed that this method will indicate the probable clinkering characteristics of a coal better than any fusion tests hereto fore described, the bureau does not recommend the general use of this method in coal Specifications until it is justified by actual trial in furnace tests of different coals. As no fusibility test of a well-mixed sample of the average ash of a coal takes into account the physical distribution of the impurities in the coal as burned, much additional investigation is needed to establish the exact relation of these labora tory fusibility tests to clinker formation. In order to correlate this proposed test of minimum softening temperature with clinker forma tion, the bureau is now making clinkering tests in a specially designed experimental furnace, in which different coals having ashes that differ in fusibility are burned under similar and known conditions of combustion. The results of this investigation will be published in a subsequent report. In the meantime it is hoped that other investigators will obtain similar correlation data.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Carbonisation of Coal: A Scientific Review of the Formation, Composition and Destructive Distillation of Coal for Gas, Coke and by-Products The Cantor Lectures which I gave in the winter of 1911 at the Royal Society of Arts, on the Carbonisation of Coal, brought me so many letters of inquiry on various points connected with the subject that I thought it might be of interest to some at least of those engaged in carbonising work if I took the lectures as a basis for a short treatise on the subject, and I think the absence of any book dealing at all fully with the scientific side of carbonisation justifies the attempt. During the last forty years I have been interested in many fuel problems, and have had the good fortune during that period to assist at the birth of most of the new departures from the recognised rut of procedure, and also, I regret to say, have been a mourner at the funerals of many.

Book excerpt: Excerpt from Effects of Storage Upon the Properties of Coal It will be seen from this summary that the most serious part of the problem relates to the matter of spontaneous heating, and prob ably the least serious phase relates to deterioration and actual loss of heat values. It is certain that at the present time a better under standing of these difficulties has been reached, and there is reason for believing that this better understanding of the fundamental principles involved will lead to some practicable and safe procedure for the stocking of bituminous coal.
