Coal bunkers, coal drop hoppers and coal conveying pipelines in thermal power plants and coking plants are high-risk areas within the factory. Finely crushed pulverized coal accumulated over a long period tends to generate static electricity during stacking and friction, which may trigger spontaneous combustion — a prominent hidden danger in coal bunker operation and maintenance.

Coal bunker fire prevention cannot be neglected! Flame-Retardant Polyethylene Liner features self-extinguishing performance away from fire, eliminating risks of pulverized coal spontaneous combustion and static sparks. It builds a fundamental safety barrier for industrial and mining coal conveying systems, suitable for renovation and new installation of all types of coal bunker linings.

Conventional coal bunkers are mostly made of ordinary steel plates, which easily trap coal and dust. Continuous friction with materials over time generates persistent static electricity, and the steel itself has no flame retardant properties. Excessive accumulated pulverized coal and excessive static buildup can easily ignite fires. Such incidents disrupt normal equipment operation, create severe safety hazards, increase workload for maintenance staff and raise difficulties in factory safety management.

Optimized and upgraded to adapt to working conditions of coal bunkers, Flame-Retardant Polyethylene Liner boasts core self-extinguishing performance. It quickly extinguishes fire sources when exposed to open flames or high temperatures without sustained combustion and flame spread, fundamentally avoiding pulverized coal spontaneous combustion risks. Its special material barely produces static electricity under friction, effectively eliminating safety threats posed by static sparks during equipment operation.

In addition, Flame-Retardant Polyethylene Liner adapts to harsh coal bunker environments with high humidity and heavy dust. It drastically reduces wet coal adhesion to walls and coal dust accumulation, cutting down manual bunker cleaning frequency. Frequent maintenance and repairs are no longer required. While boosting coal bunker safety, it greatly improves the operational stability of coal conveying systems.
