Core Points - The "Liaohe into Jinan" project has successfully completed the northern line, marking the longest and largest heat supply pipeline in China, with a total length of 110 kilometers and a diameter of 1.6 meters [1][3] - The project utilizes waste heat from the Xinyuan Power Plant in Liaocheng to provide clean heating to Jinan, significantly reducing coal consumption and carbon emissions during the heating season [3][5] - The southern line of the project is expected to be completed by the end of the year, bringing the total length of the north-south lines to approximately 150 kilometers, capable of heating 1 million square meters [5] Summary by Sections - **Project Overview**: The "Liaohe into Jinan" project aims to convert waste heat from Liaocheng's power plant into a clean heating source for Jinan, addressing the city's increasing heating demand and energy structure adjustment [3][7] - **Environmental Impact**: The project is projected to reduce coal consumption by 1.2989 million tons and cut carbon dioxide emissions by 3.564 million tons each heating season, equivalent to the carbon sequestration of four Saihanba forests in a year [5] - **Construction Challenges**: The project spans three cities and five counties, passing through 140 natural villages, with significant construction challenges, particularly the southern line's tunnel under the Yellow River, which required overcoming high water pressure and complex geological conditions [5][7] - **Future Developments**: By the end of the year, all 54 coal-fired heating boilers in Jinan's main urban area will be shut down, further enhancing the city's environmental sustainability [7]

10月26日上午，随着"聊热入济"工程北线齐河段潘庄引黄干渠顶管处最后一处断点打通，"聊热入济"长距离供热工程北线实现全线贯通，开始全线冷态调 试，将在今冬供暖季投入运行。 "聊热入济"工程是指利用山东聊城的电厂余热"变废为宝"，为济南市区提供"域外热源"的供热工程。本次贯通的北线，在今冬供暖季将把山东聊城信发集团 信源电厂的余热，化作管道中的高温水流，为济南中心城区输送清洁热源。这条长110公里、管径1.6米的"超级暖气管"，是目前我国最长、管径最大、供热 能力最强的长输供热管道。 新聞 8 14.9 . th i . . r ation HD 2006-0 除了北线，"聊热入济"南线也将于年底前贯通。届时，总长约150公里的南北两线可为济南供暖1亿平方米，预计每个供暖季可减少标煤消耗129.89万吨，减 排二氧化碳356.4万吨，相当于4个塞罕坝林场一年的固碳量。 将百公里外的热源"搬运"进城并非易事。"聊热入济"工程横跨3市5县（区），途经140个自然村，重要点位达110处。其中，南线穿黄隧道施工难度最大，供 热管道需在黄河河床下"潜行"4500米，最大埋深达55米。施工方克服高水压、复杂地质、大坡度掘 ...
