The pulverized coal bin process analysis system is an important piece of equipment for ensuring industrial production

The pulverized coal bin process analysis system is a key piece of equipment for ensuring industrial production. It can continuously monitor the levels of combustible gases and oxygen in the bin in real time, promptly identify potential risks such as explosions, and significantly reduce the likelihood of accidents through alarm and interlock control mechanisms, protecting both equipment and personnel. The system utilizes advanced sensor technology and multi-parameter detection methods to accurately and stably measure the concentrations of various gas components, providing reliable data support for process control and adjustment. Its automation features include automatic sampling, purging, drainage, and analysis output, effectively reducing manual intervention, improving work efficiency and system reliability, and minimizing human errors. Additionally, by accurately analyzing the gas composition inside the pulverized coal bin, the system can also provide data references for blast furnace process control, helping operators optimize production parameters and achieve better combustion efficiency and energy utilization.

• Strictly control inventory and storage time: Avoid excessive storage of coal powder and minimize the storage time in the bin to reduce the risk of spontaneous combustion.
• Install explosion-proof facilities: Install explosion-proof valves on the coal powder system pipelines and equip equipment such as coal powder bins, separators, and cyclones with explosion-proof doors that meet the volume ratio requirements. The explosion-proof door frames should be strong and airtight enough. In the event of an explosion-proof valve (door) bursting, immediately shut down the equipment, eliminate the source of ignition, and only restart after repairs.
• Add temperature monitors: Install temperature monitoring devices at key locations such as coal powder bins, separators, and cyclones to monitor temperature changes in real time and prevent spontaneous combustion or explosion caused by high temperatures.
• Prevent powder accumulation in pipelines: Avoid horizontal sections in the coal powder system pipelines to reduce powder accumulation.
• Maintain proper interlocks: Mechanical equipment in the coal powder preparation system should be equipped with interlocks and kept in good working condition to automatically shut down in case of an accident and prevent the accident from spreading.
• Electrical equipment explosion-proof requirements: Electrical equipment in the coal powder preparation area must meet explosion-proof standards to prevent explosions caused by electric sparks.
• Regularly calibrate measurement points and alarm devices: Regularly calibrate temperature, pressure, flow rate measurement points and related alarm devices in the pulverization system to ensure their accuracy and effectiveness.
• Reduce horizontal pipe sections: Minimize horizontal pipe sections during system design to ensure tight systems with smooth inner walls and no powder accumulation dead corners.
• Follow design specifications: The design of coal bins, powder bins, pulverization and powder conveying pipelines, system valves, explosion-proof pressure and explosion-proof doors must strictly comply with relevant specifications.
• Equip with fire protection and inerting systems: For coal types with strong explosion characteristics, the pulverization system should be equipped with fire protection and inerting systems, with stable gas (air) sources and hydrophobicity meeting design and operating requirements, and regular maintenance and inspections should be carried out.
• Install loosening devices: Raw coal bins should be equipped with suitable loosening devices to prevent blockages, coal bridging, caking, or local voiding.
• Strengthen explosion-proof door management: Regularly inspect explosion-proof doors to ensure the explosion-proof film has sufficient area and specified strength, and pay attention to the direction and range of the ejected material during operation to avoid harm to personnel and equipment.
• Tight and smooth connections: During system installation, ensure tight connections and smooth inner walls to prevent local powder accumulation.
• Implement "three separations" and debris removal: Strengthen debris removal from the coal entering the furnace to ensure stable operation of the pulverization system.
