Excerpt from Drying and Preheating Coals Before Coking: Part 2. Coal Blends Following coking tests on preheated individual coals, described in our Circular 423, similar studies have been made on four coal blends, all of which were dried and preheated over a range of 230 to 450 F before coking. It has been shown that preheating consistently reduces the coking time, thereby increasing the potential coking capacity of a coke-oven battery. This increase in capacity for the blends studied ranged from approximately 25 to 50 percent at the highest preheat temperatures tried. It also has been shown that coke strength is not affected appreciably by preheating blends that are capable of producing strong coke without preheat. Coke sizing is not greatly affected, nor are coke or tar yields. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
