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.

Blast Furnace Ironmaking: Analysis, Control, and Optimization uses a fundamental first principles approach to prepare a blast furnace mass and energy balance in ExcelTM. Robust descriptions of the main equipment and systems, process technologies, and best practices used in a modern blast furnace plant are detailed. Optimization tools are provided to help the reader find the best blast furnace fuel mix and related costs, maximize output, or evaluate other operational strategies using the ExcelTM model that the reader will develop. The first principles blast furnace ExcelTM model allows for more comprehensive process assessments than the 'rules of thumb' currently used by the industry. This book is suitable for undergraduate and postgraduate science and engineering students in the fields of chemical, mechanical, metallurgical and materials engineering. Additionally, steel company engineers, process technologists, and management will find this book useful with its fundamental approach, best practices description, and perspective on the future. - Provides sample problems, answers and assignments for each chapter - Explores how to optimize the blast furnace operation while maintaining required temperatures and gas flowrates - Describes all major blast furnace equipment and best practices - Features blast furnace operating data from five continents

​This book describes the available technologies that can be employed to reduce energy consumption and greenhouse emissions in the steel- and ironmaking industries. Ironmaking and steelmaking are some of the largest emitters of carbon dioxide (over 2Gt per year) and have some of the highest energy demand (25 EJ per year) among all industries; to help mitigate this problem, the book examines how changes can be made in energy efficiency, including energy consumption optimization, online monitoring, and energy audits. Due to negligible regulations and unparalleled growth in these industries during the past 15-20 years, knowledge of best practices and innovative technologies for greenhouse gas remediation is paramount, and something this book addresses. Presents the most recent technological solutions in productivity analyses and dangerous emissions control and reduction in steelmaking plants; Examines the energy saving and emissions abatement efficiency for potential solutions to emission control and reduction in steelmaking plants; Discusses the application of the results of research conducted over the last ten years at universities, research centers, and industrial institutions.

Combustion technology has traditionally been dominated by air/fuel combustion. However, two developments have increased the significance of oxygen-enhanced combustion-new technologies that produce oxygen less expensively and the increased importance of environmental regulations. Advantages of oxygen-enhanced combustion include less pollutant emissi
