Technical Specification for Oxygen-Enriched Blast Furnace Coal Injection

This technical specification outlines the requirements and guidelines for the application of oxygen enrichment in blast furnace coal injection processes. It establishes procedures for planning, implementation, and control to optimize fuel consumption and enhance production efficiency in ironmaking operations. The document addresses critical aspects such as oxygen supply stability, coal preparation parameters, and injection system performance metrics. It also defines safety measures to prevent potential hazards associated with high-velocity coal and enriched oxygen environments within the furnace structure. The content includes technical criteria for monitoring and evaluating the combustion efficiency of pulverized coal. By adhering to these provisions, steel manufacturing facilities can achieve more consistent operational stability and reduced energy expenditure. The standard serves as a reference for technical personnel involved in process optimization, equipment maintenance, and operational safety management. It emphasizes the importance of precise control over the mixing ratio and distribution of oxygen and coal to ensure sustainable production. Implementation involves regular assessments of equipment condition and adherence to prescribed operational limits.
