Fire and Explosion: The primary risk associated with coal mills is the potential for fire and explosion. Coal dust, when mixed with air, can become highly combustible. Ignition sources such as sparks, hot surfaces, or electrical malfunctions can trigger fires or explosions.

The main objective is to prevent and mitigate fires in coal storage, handling, and processing areas, ensuring safety, operational continuity, and environmental compliance. Here are some key aspects and measures for coal fire protection: 1. Detection Systems. Thermal Sensors: Detect abnormal temperature rises in coal piles or conveyor systems.

Water fogging and deluge systems are essentially mill internal combustible dust suppression systems and they also suppress or extinguish burning or smoldering coal. The majority of burning or smoldering coal more often occurs under the grinding zone where the hot primary air flow enters the mill.

Constructional explosion protection in coal grinding plants includes: 1. Protection of ducts for effective mitigation of flame front propagation. 2. Protection of dedusting filters through safe pressure relief (according to DIN EN 14491, NFPA 68). 3. Protection of storage silos through safe pressure relief (according to DIN EN 14491, NFPA 68 ...
