適用範囲

This standard specifies the basic requirements for explosion prevention and protection measures in the pulverized coal system of ironmaking blast furnaces. It applies to the design, construction, acceptance, operation, maintenance, and management of new, expanded, or renovated projects for injecting bituminous coal or mixtures of bituminous and anthracite coal. Anthracite coal injection systems may refer to this standard for implementation. It is primarily targeted at facilities within the metallurgical industry.

技術要求

The standard outlines comprehensive safety protocols to mitigate fire and explosion risks associated with coal dust. It mandates strict control over hazard factors such as spontaneous combustion of raw coal, temperature spikes, and oxygen leakage into inerted equipment. Designated personnel must be fully aware of system functions and explosion risks. For system design, it specifies requirements for inerting systems, requiring the use of inert gases like nitrogen as drying and carrying mediums to maintain oxygen levels below critical thresholds. Equipment such as coal powder bins and injection tanks must be designed with smooth walls and adequate angles to prevent dust accumulation, and all electrical components must follow GB 50058-1992 for hazardous area classifications. The standard also details explosion venting and suppression mechanisms. All coal powder containers and pipelines must be equipped with sufficient venting areas, and emergency nitrogen injection systems must be installed in critical components like coal mills and bag filters. Systems must feature reliable safety interlocks to automatically shut down or switch to inert gas during emergencies. Operational guidelines cover startup, running, and shutdown procedures, emphasizing continuous monitoring of temperature, pressure, and gas concentrations. Emergency protocols are established for scenarios like coal mill fires, power outages, and ruptured explosion discs, prioritizing the use of inert gases over water jets for extinguishing metal dust fires.

試験方法

The standard emphasizes continuous online monitoring rather than standalone laboratory testing. Facilities must install fixed monitoring devices for oxygen content and carbon monoxide concentration in the coal preparation system. Temperature monitoring with alarms is required at mill inlets and outlets, bag filters, and coal powder bins. Regular calibration of pressure, temperature, and gas monitoring instruments is mandatory to ensure system reliability. System commissioning requires sequential testing (single machine, no-load, and load tests) using anthracite coal to verify the sensitivity of interlocks and alarms.

よくある質問

What products or systems are regulated under GB 16543-2008?

GB 16543-2008 regulates the bituminous coal injection systems used in blast furnaces within ironmaking plants. This includes the entire process from raw coal storage and drying to pulverized coal preparation, conveying, and injection.

Is GB 16543-2008 a mandatory standard?

Yes, with the exception of a few specific clauses (such as 4.11, 5.1.1, etc.), the majority of the provisions in GB 16543-2008 are mandatory. Compliance is legally required for relevant facilities operating in China.

What are the key safety measures required for coal powder containers?

The standard requires coal powder containers to have smooth internal walls, sufficient explosion venting areas, and continuous nitrogen inerting systems. They must also be equipped with temperature monitoring and emergency fire suppression systems using inert gases or steam.
