Coal bunker blockage, wall adhesion, and arching are common problems encountered in the daily operation and maintenance of fuel departments in thermal power plants. Wet coal and pulverized coal easily adhere to the bunker walls, causing feeding delays, power outages, and shutdowns, severely impacting the stable operation of the unit. UHMWPE coal bunker liners, with their unique material properties, have become the core solution for solving blockage problems in thermal power plant coal conveying systems, fundamentally improving the operating conditions of the coal bunker.

UHMWPE coal bunker liners possess excellent self-lubricating properties and a low surface friction coefficient, far superior to traditional steel bunker walls. During the transportation and storage of raw coal, the ultra-high molecular weight polyethylene coal bunker liner does not adhere to wet coal powder or sticky coal slurry, allowing coal to slide smoothly and effectively solving the problems of coal seam accumulation, wall adhesion, and caking, eliminating the need for high-frequency impact from air cannons and manual cleaning operations.

Under the long-term continuous production conditions of thermal power plants, UHMWPE coal bunker liners not only consistently achieve anti-blockage and anti-sticking effects but also possess excellent wear resistance and impact resistance. Faced with continuous scouring and impact from coal lumps, the non-stick coal bunker liner exhibits low wear and tear, effectively protecting the bunker's structural integrity, reducing equipment wear and aging, and lowering the frequency of coal conveying system failures and maintenance pressure.

Compared to traditional unblocking and modification methods, the application of UHMWPE coal bunker liners eliminates the need for frequent maintenance, ensuring unobstructed coal flow for extended periods. This avoids the safety hazards of unblocking in confined spaces, guaranteeing continuous, safe, and efficient coal conveying operations in thermal power plants, and effectively addressing a core maintenance pain point in the fuel department.
