In January 2024, a heating pipeline rupture occurred in Tongliao City, Inner Mongolia, releasing a large plume of high-temperature steam that blanketed the area in dense white vapor, drawing public attention. The incident took place near a major downtown road, involving a section of the city’s centralized district heating network. With winter temperatures dropping below minus 20°C, the hot steam instantly condensed upon contact with the cold air, creating a dramatic cloud of mist often mistaken for smoke from a fire or explosion. Local heating authorities responded promptly, shutting off valves and initiating emergency repairs. Fortunately, no injuries were reported. Preliminary investigations suggest the rupture was caused by aging infrastructure and thermal stress from repeated expansion and contraction. In response, Tongliao has launched a citywide safety inspection of its heating pipelines to prevent similar incidents. This event underscores the critical need for regular maintenance and upgrades of urban infrastructure, especially in frigid regions where reliable heating systems are essential for both daily life and public safety.
2024年1月，内蒙古通辽市发生一起供暖管道破裂事故，导致大量高温蒸汽喷涌而出，现场白雾弥漫，引发市民关注。事发地点位于市区主干道附近，破裂管道属于城市集中供热系统的一部分。由于冬季气温低至零下20多摄氏度，高温蒸汽遇冷迅速凝结成水雾，在空中形成浓密‘白烟’，视觉效果震撼，一度被误认为火灾或爆炸。当地供热公司迅速响应，关闭相关阀门并组织抢修，未造成人员伤亡。事故原因初步判断为管道老化及热胀冷缩应力集中所致。通辽市已启动全市供热管网安全排查，以防范类似事件再次发生。此类事件提醒城市基础设施需定期维护更新，尤其在严寒地区，供暖系统的安全运行直接关系到居民生活质量和公共安全。
