Print on Demand. This book marries historical findings with an innovative method for studying coal composition to challenge prevailing theories. The author questions the nature of the coal formation process using new techniques to separate inherent components of coal and then studying their properties. The research presented adds valuable insight into coal as it naturally occurs, enhancing our understanding of its formation process, its properties and its behavior in various applications. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

I. Present 'methods of Coal Analysis. - There are two processes in vogue at the present time for the chemical examination of coal; one is the ultimate, and the other is the proximate method of analysis. In the first the organic or' combustible part Of the coal is separated into its elemental constituents, carbon, hydrogen, oxygen, and nitrogen. The mineral or non-combustible portion is separately determined under two items as ash and moisture.
In the proximate method the organic material is separated into two divisions, one being that portion which under high temperature and out Of Contact with the air passes off in the gaseous form, and the other that part which remains behind as the non-volatile or coke-form ing carbon.
Each procedure has doubtless come into use as the result of a specific demand. For example, the engineer needed the data from which he could calculate the total heat of the coal and, in arriving at a heat balance, he must also have at hand any negative factors charge able to the fuel, such as the quantity and character of the gaseous products of combustion. These items, therefore, would call for the data furnished by the ultimate methods of analysis.' The proximate method was developed as a natural accompaniment of the gas and coke industries, since it furnished in either case an index of the yield which might be expected from a given coal. Formerly, also, the quantity of volatile matter was made to serve as an index of the grade or quality of a coal. Thus the data from proximate analyses have been put into the form of fuel ratios or the ratio of the non-volatile to the volatile part of the coal, such ratios supposedly serving as an indication of the general class or type to which the coal belonged.
