全长110公里！“超级暖气管”全线贯通

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]
