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.

Combustion behavior of pulverized coals (PC), gasification and thermal annealing of cokes were investigated under controlled environments. Physical and chemical properties of PCI, coke and carbon residues of blast furnace dust/sludge samples were characterized. The strong influence of carbon structure and minerals on PCI reactivity was demonstrated. A technique to characterize char carryover in off gas emissions was established.

This unique book presents an in-depth analysis of all the emerging ironmaking processes, supplementing the conventional blast furnace method. Various processes for producing solid and liquid iron are discussed, including important features such as process outline, techno-economics, and process fundamentals. The present global status of each process is examined, projections for the future are made, and processes are compared. Beyond the Blast Furnace is valuable reading for process developers, because it gives them a complete picture of various process options. Conventional iron- and steelmakers as well as researchers and practitioners working in the area of alternative processes of ironmaking will also benefit from this ready reference. The book is an ideal text for undergraduate and postgraduate students in metallurgy.

Réalisée dans le but de vérifier les procédés entourant l'injection du charbon dans les hauts fourneaux, cette étude vise à déterminer dans quelle mesure cette technique est applicable aux charbons canadiens. Elle fait état des recherches et des données opérationnelles découlant de plusieurs travaux effectués par des entreprises industrielles. Les éléments qui influent sur l'injection de charbon, en particulier les caractéristiques du charbon, la combustion et les systèmes mécaniques de même que les aspects pratiques et théoriques sont passés en revue. Le rapport présente une étude des critères d'évaluation qui reposent sur la teneur en cendre et en matière volatile du charbon et propose une méthode de rechange basée sur la caractérisation complète des produits résultant de la pyrolyse.

This book focuses on how to keep blast furnaces running stably and smoothly with low consumption and long operating life spans. Assessing and adjusting blast furnace performance are key to operation. The book describes in detail cases of both successful and failed blast furnace operation. It also demonstrates various phenomena and “symptoms” in the smelting process that have rarely been studied before, e.g. abnormal gas distribution, bending loss of tuyere, slag crust fall-off, blast furnace thickening, and hearth accumulation. As such, it will help readers understand internal phenomena in blast furnaces, providing a basis for developing intelligent control and management systems.
