Paperback. Condición: New. Print on Demand. This book explores the potential benefits of partially drying coal before it is charged into commercial coke ovens. By analyzing the results of predrying five coal blends, the author investigates how this process can improve oven productivity, decrease coking time, and affect the physical properties of the resulting coke. The findings suggest that predrying coal at temperatures of up to 250°F can reduce coking time by 25 to 35 minutes for each percent of moisture removed, and increase oven productivity by a similar percentage, making this technique a promising method for optimizing coke production.

Paperback. Condición: New. Print on Demand. This book presents research that explores how to predict coke quality. Coke is the crucial component of blast furnaces used to produce materials such as steel. The book details a method developed by the author that uses petrographic analysis of coal to predict coke's quality and stability factor. The author reviews prior methods for assessing coke quality and notes their limitations. They then establish a detailed process to measure reflectance values of the most abundant component in coal and define inert and reactive components. The author also provides mathematical equations and graphs to aid in the calculation of coke stability factors from coal samples. The work is of significance because prior assessments of coke quality were imprecise or required expensive and time-consuming laboratory tests. The author's method offers a rapid alternative that uses easily accessible equipment and provides a reliable assessment of coke stability.

Paperback. Condición: New. Print on Demand. This book is the product of years of dedicated research and collaboration between the Illinois State Geological Survey and the steel and coke industries in the Chicago and St. Louis areas. The book explores the possibility of utilizing all, or a very large percentage, of Illinois mine coal output for coke, rather than the previous practice of using only larger coal sizes, to determine economic advantages for both coal and coke producers. To this end, the author analyzes the effects of using wider size ranges, including 2" x 10 mesh and 3" x 0, from the standpoint of preparation, coking properties in blends, and weathering characteristics. Tests conducted by the author have indicated that coals in these size ranges, from Illinois mines supplying coal to the coke industry, may be prepared to a satisfactory analysis, and that their blends produce cokes with physical properties comparable to those made with only the larger coal sizes. The book concludes that the size range of Illinois coal previously recommended for coke production may be extended to include properly prepared sizes down to 10-mesh or 0 and that these coals may be stockpiled throughout the summer months if they are to be blended subsequently with fluid coals. Thus, the research presented in this book provides valuable insights into expanding the range of Illinois coals that can be used for coke production, potentially leading to economic benefits for both the coal and coke industries.

Paperback. Condición: New. Print on Demand. This book presents an insightful examination of the successful use of medium-volatile coals in metallurgical coke blends. Historically, low-volatile Pocahontas coal has been used for blending, but the author explores the potential of medium-volatile coals as a cost-effective and equally viable alternative. The author provides a thorough analysis of the coking properties of medium-volatile coals from different seams, highlighting their high fluidity and strong coking characteristics. These qualities make them suitable for blending with lower-fluidity Illinois coals, resulting in coke with excellent physical properties. The book delves into the technical aspects of coke production, including coking time, expansion pressure, and coke size distribution. It demonstrates the ability of medium-volatile coals to produce coke with high strength indices, minimal breeze, and optimal size for blast furnace use. The significance of this book lies in its practical implications for the metallurgical coke industry. It offers a valuable understanding of the properties and benefits of medium-volatile coals, enabling coke producers to optimize their blending strategies and improve coke quality. By providing a comprehensive analysis of this innovative approach, the author contributes to the advancement of coke production practices and the efficient utilization of coal resources.
