Paperback. Condition: New. Print on Demand. This book explores water-gas production practices from 1918, comparing the use of coke and bituminous coal from the central United States as generator fuel for industrial water-gas production. It highlights the predominant use of coal and coke in early 20th century manufacturing and outlines the reasons for substituting bituminous coal for coke. The text uses real-world examples from twenty water-gas plants across the United States that had successfully transitioned from coke to bituminous coal, demonstrating a potential cost-saving benefit. Through operational data and case studies, the author reveals that while bituminous coal reduced production capacity by an average of 25%, the lower cost of coal, coupled with a reduction in necessary oil, resulted in lower overall manufacturing costs. The author concludes that these central district coals were successful substitutes for more expensive coke, providing new opportunities for industries using water-gas as a fuel source.
