Paperback. Condizione: New. Print on Demand. This book provides a straightforward method for accurately determining the combustible content of shale, clay, and carbonate rocks. The presence of combined water and the formation of insoluble materials during analysis can lead to inaccurate results. As a result, the author has devoted considerable space to explaining how to identify and avoid any potential problems during analysis. Despite its technical nature, this book is well-suited to a general audience. The author takes care to explain complex concepts in clear and accessible language, while also providing extensive data that illustrates the need for a precise method for identifying combustible content in silicate and carbonate rocks. 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. print-on-demand item.

Paperback. Condizione: New. Print on Demand. This book provides a method for determining the incombustible matter in coal and rock-dust mixtures in mines. Using a volumeter, the author explains the theory of the apparatus and presents results of its use for synthetic and miscellaneous samples. The data provided demonstrates that the volumeter method is capable of results accurate within 1%, which is greatly advantageous in monitoring the addition of rock dust to coal mines as a protective measure for preventing dust explosions. The volumeter has become widely adopted and continues to have relevance as a monitoring tool to this day.

Paperback. Condizione: New. Print on Demand. This book compiles and presents analyses for a wide array of coal samples collected by the U.S. Bureau of Mines and the U.S. Geological Survey between 1916 and 1919, many of which have been used for testing the heating and industrial value of coal from different locations for government projects. The book contextualizes the development of coal analysis methodologies within the history of fuels research and technology. Via charts and tables, the author presents proximate and ultimate analyses for hundreds of samples, which the author collected from a variety of sources including mines, outcroppings, and prospect holes. These analyses provide insights into the chemical composition, heating value, and other properties of these diverse coal samples. This exhaustive collection of data is a valuable resource for geologists, mining engineers, fuel chemists, and others, serving as a foundation for planning, evaluating, and implementing a variety of coal-based projects.
