科技创新“显身手”实现更绿色、更高效煤炭保供 供暖季供电供暖保障有力

Core Viewpoint - The article highlights the efficient and environmentally friendly coal transportation system in Inner Mongolia, specifically the "light bulb line" at Hohlinhe Station, which plays a crucial role in supplying coal to the northeastern regions of China during the peak heating season. Group 1: Transportation Efficiency - The "light bulb line" is a 5.2-kilometer circular loading line that allows trains to load coal without stopping or turning around, significantly enhancing transportation efficiency [1][4] - The loading process utilizes an automatic weighing system, with a loading time of only 50 seconds per car, enabling a 110-car train to be fully loaded with over 7,500 tons of coal in just two hours [6] - At peak times, the system can load 1,232 cars in a single day, with an annual transportation capacity of up to 17 million tons [6] Group 2: Environmental Considerations - The loading system is fully enclosed and employs dust suppression technology, preventing dust emissions during coal transportation [8] - After loading, a dust suppressant is automatically sprayed on the coal surface, creating a 10-millimeter thick "liquid tarpaulin" that effectively reduces dust and loss during transport [8] Group 3: Operational Support - The railway department has established a "green channel" for coal trains, prioritizing the allocation of empty cars and scheduling [10] - The circular loading lines operate 24/7 to ensure a continuous and rapid supply of coal to power plants [10] - Since 2025, these lines have cumulatively transported over 68 million tons of coal, supporting more than 50 power plants in Liaoning, Jilin, and eastern Inner Mongolia [11]
