Explosion-proof safety specifications for blast furnace bituminous coal injection systems

1 Scope

This document specifies the general measures for preventing and protecting against pulverized coal explosions in blast furnace injection systems and mixed coal injection systems in ironmaking plants. The requirements, including detailed requirements for buildings and structures, process systems and equipment, explosion control measures, and operational safety management, describe the relevant requirements. The corresponding verification method. This document applies to the design of pulverized coal explosion prevention and protection measures in blast furnace injection bituminous coal systems and blast furnace mixed coal injection systems in ironmaking plants. Production, maintenance, repair and management.

3 Terms and Definitions

The terms and definitions defined in GB/T 15604 and the following terms and definitions apply to this document. 3.1 An aggregate of dry, ash-free coal particles with a volatile matter content higher than 10%, capable of being suspended in an airflow. Note. Abbreviated as "pulverized coal". 3.2 The entire production system includes raw coal storage and transportation, drying, pulverized coal preparation, pulverized coal transportation, and pulverized coal injection into the blast furnace after the raw coal enters the pulverized coal injection area of the ironmaking plant. 3.3 The process begins with the raw coal bunker, then moves to the heating furnace and its gas supply system, and finally to the pulverized coal silo, where raw coal is dried, ground into pulverized coal, and then collected and stored. ...
