Paperback. Condizione: New. Print on Demand. This book explores themes of industrial innovation by examining the effects of coal handling in mid-20th-century metallurgy. The author leans on extensive research and experimentation to demonstrate how coal preheating technologies brought considerable benefits to the steel industry between 1956 and 1968. By analyzing various coal blends, the book illustrates how efficiency gains could be made by drying and preheating coal before coking. The author concludes that preheating coal resulted in faster coking times, increased coke oven capacity, and reduced production costs. The insights provided in this book are highly relevant to professionals in the steel and energy industries today, as they provide a basis for innovations in metallurgy and industrial 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.…
