In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column. The capacity of the furnace to consume these particles by solution loss is probably one of the limitations to coal injection. It is, therefore, important to understand the physicochemical and aerodynamic behaviour of fines including the change of in-furnace phenomena.The Committee of Pulverized Coal Combustion and In-Furnace Reaction in BF was set up in 1993 as a cooperative research of the Japan Society for the Promotion of Science (JSPS) and the Iron and Steel Institute (ISIJ) to evaluate research initiative into this problem.This book reports on the JSPS/ISIJ Committee's activities and describes the interpretation of findings drawn from combustion experiments and the results of live furnace applications, and furnace performance.

Coke: Quality and Production describes the scientific and technical basis of coke manufacture and provides a detailed account of the physical and chemical mechanisms occurring in coke oven chambers. Emphasis is on the influences of coal quality and production parameters. This book is comprised of 12 chapters and begins with an introduction to technical characteristics displayed by coals or cokes, followed by a discussion on the chemical, physicochemical, and mechanical phenomena that occur during carbonization. The following chapters focus on carbonization in a coke oven chamber and its relationship to coke quality; the criteria used to evaluate coke quality; and industrial and semi-industrial tests carried out at the Marienau Station in France. The formulation of coke oven blends is also considered, along with the production factors that affect the quality of coke; factors that affect the production capacity of a coke oven battery; and heat balances on industrial coking plants. The final chapter looks at the industrial applications of blast-furnace coke and foundry coke. This monograph is intended primarily for technical personnel at coking plants and will also be of interest to consumers concerned with the working properties of coke.

Methods of Working Coal and Metal Mines, Volume 3 discusses the extraction of mineral deposits, which involves the driving of development openings, from the surface or a central shaft, to the “block out” portions of the deposit. This book is divided into three parts. Part A describes the coal mining methods, which include pillar mining systems and long-wall mining. Economics of coal face mechanization is also discussed. In Part B, the classification of stoping systems, which is comprised of pillar-supported stopes, timber and fill supported stopes, and slicing or caving systems, is elaborated. This part also emphasizes the mining bedded metalliferous ores, as well as the costs and other factors affecting the choice of mining systems. Part C deliberates the surface mining methods, which consist of strip mining of coal, open-pit mining, and stability of pit slopes. This publication is intended for mining engineers, but is also useful to students and researchers conducting work on the application of extracting and processing minerals.
