Paperback. Condition: 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 physi…cal 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. 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. Condition: 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. 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.
