经济上行期的蒸汽节能改造系统要如何破局？

日期： 2025-12-15 作者：晟德亿编辑

目前随着经济的不断发展，我国的能源生产和消耗都已经处在世界的前列，但是人均能源占有值却很低，煤炭是世界人均占有的1/4，石油是世界人均占有的1/40。与此同时，我们能源综合利用效率仅仅30％，而日本的能源综合利用效率为52％，也远不及其他发达国家。在许多企业常见到的蒸汽放空，凝结水直排就是最直观的反映，是企业的产品成本高居不下的重要原因，直接影响着企业的生存能力和国际竞争力。

我国是能源消耗大国，以占全球15%左右的GDP消耗了全球23%的能源。截止到2021年，我国对煤炭的依赖程度高达56%，能源转型的任务十分艰巨。在工业生产领域，蒸汽占企业总能耗的30%以上。其中，在化工和石油加工行业蒸汽占到总能耗的50%，在轮胎行业蒸汽占总能耗的70%，在印染行业、制浆造纸行业蒸汽在总能耗的占比高达80%。我国实现绿色低碳可持续发展的核心是提高能源利用效率，据研究，我国蒸汽系统的平均节能潜力可以达到43%以上，潜力巨大。

此外，随着环保要求的不断提高，供热企业均逐步实现了煤改燃，导致蒸汽成本上涨。很多供热企业开始上调蒸汽价格，用汽企业也开始寻求节约蒸汽的方法。因此，无论从节能方面，还是成本控制方面考虑，节约蒸汽都是企业目前面临的必选之路。

蒸汽是化工企业最常见的二次能源之一，它能实现企业生产所需要的换热、伴热、机械驱动力、工艺混合蒸汽以及采暖吹扫等辅助功能。蒸汽产生的凝结水系统也是全厂值得关注的重要热量载体系统。蒸汽系统是化工企业能量流的最大交换平台，因此通过实施对蒸汽动力系统进行节能改造优化，保障蒸汽、凝结水系统的稳定高效运行，对提升企业的市场竞争力具有十分重要的意义。

要真正实现企业蒸汽、凝结水系统的稳定高效运行，必须要改变观念，依靠科技，全局着眼，重点突破。
